Authors: Sk Zakki Uddin, Nirupama Panda, G.V.Anjana, M. K. Kathiravan
Pages: 1 - 12
Abstract: Tuberculosis (TB) is an infectious lung disease. Tiny droplets discharged into the air during cough and sneezes by an individual can transmit the bacteria that cause tuberculosis from one person to another. More than one million people die each year as a result of the communicable disease tuberculosis. Anti-TB allopathic drugs have been administered to treat the disease’s symptoms; however, they can produce negative side effects such as hepatitis, hypersensitivity reactions, nausea, vomiting, etc. As a result of the toxicity and side effects of allopathic medicines, the use of herbal medicine is growing in popularity. Since ancient times, medicinal plants have been used to treat illnesses. Alkaloids, coumarins, flavonoids, polyphenols, terpenoids, quinines, and other secondary metabolites that have antibacterial activity are produced by plants and may be helpful in the treatment of tuberculosis. This review aims to explore the possible uses of medicinal herbs and metal complexes with antitubercular capabilities.

- Chemopreventive Potential of Phytoestrogens on Hormone-Sensitive Cancer -
An Updated Review
Authors: S.Priyadharshini Subramani, Jubie Selvaraj, Jawahar Natarajan
Pages: 23 - 33
Abstract: Hormone-dependent cancers contribute to the majority of cancer deaths in women. Treatment options for hormonal cancer such as breast, endometrial, prostate, and ovarian cancer aim at inhibiting key signalling pathways and hormones responsible for cell proliferation. Hormonal therapies in the long run cause musculoskeletal disorders, Disease reoccurrence, and drug resistance. There is a need for new alternative therapies to prevent and treat hormonal carcinomas. Phytoestrogens, a naturally occurring polyphenol have potent effects on hormonal cancers due to their estrogenic effects. Evidence suggests that phytoestrogens exert their apoptotic potential by interfering with steroidogenesis, gene expressions, and down-regulation of Protein Tyrosine Kinases, Matrix Metalloproteinases. They also act as topo-poisons. This review explains the key mechanisms of phytoestrogens in inhibiting cell proliferation in hormonal cancers by evidence from recent clinical studies, meta-analyses, and cohort study reports. Phytoestrogens have multi-target potential with both preventive and treatment properties on cancer cell lines. Combination therapies with phytoestrogens are more beneficial in controlling cell progression. Hence further research is required to explore their epigenetic properties on tumour suppressor genes which stay an important target in cancer research.

- An Updated Review on Medicinal Plants with Hepato-protective Activity
Authors: Jagdish Labhubhai Kakadiya, Yash Subhash Janve, Mohan maruga raja
Pages: 47 - 55
Abstract: Many precious medicines from traditional medicinal plants can be produced using a phototherapeutic approach to modern drug research. Finding pure phytochemicals that can be used as medicines requires time and money. The treatment of liver problems involves the use of numerous herbs and polyherbal mixtures. However, the treatments are ineffective in the majority of severe instances. Even though many of these plants and mixtures were subjected to experimental evaluations, the research was frequently insufficient and uncompleted. It was found that the therapeutic effects were evaluated in animals with subclinical liver damage brought on by a few substances. Antioxidants included in common foods can offer this kind of defence against liver damage brought on by hazardous substances’ oxidative processes. Therefore, hepato-protective natural products such as Phyllanthus amarus, Silybum marianum, Solanum nigrum, Tephrosia purpurea, Eclipta alba, Cichorium intybus, Phyllanthus Niruri, Centella asiatica, Capparis spinosa, Terminalia arjuna, Cassia occidentalis, Fumaria parviflora, Embelia ribes, Boerhaavia diffusa, Tamarix gallica, Achillea millefolium, Terminalia chebula, Ocimum sanctum, Glycyrrhiza glabra, Foeniculum vulgare, Garcinia mangostana, Acacia Catechu, Pergularia daemia, Annona squamosa, Flacourtia indica. The goal of the current review is to gather information on promising phytochemicals from medicinal plants that have been evaluated in hepatotoxicity models utilising cutting-edge scientific methods.

Authors: Pallavi Satyajit Kulkarni, Narayan Gajanan Gramopaghye, Satyajit Pandurang Kulkarni
Pages: 73 - 78
Abstract: Scorpion stings are very common in India, especially in the Konkan region of Maharashtra state. Scorpion stings show various signs and symptoms. A preclinical study to validate the efficacy of an Ayurvedic preparation called Jeerakadi Lepa was done in Swiss albino mice. A total of 18 Swiss albino mice (n = 18) were divided into 3 groups: the control group (n = 6), the standard group (n = 6) and the experimental group (n = 6). Only Indian red scorpion venom was administered by the SC route in the control group. In contrast, the venom was administered by SC in the standard group, followed by an oral tablet. Prazosin, and in the experimental group, the venom was administered by SC route, followed by local Jeerakadi Lepa. Kruskal-Wallis’s test was applied at a 95% confidence interval to assess various toxicity parameters like lacrimation, salivation, etc. The P-value was 0.04433 in toxicity symptoms (P < 0.05), but it was 0.3366 (P > 0.05) in the number of deaths of Swiss albino mice in the above groups. It was concluded that Jeerakadi Lepa effectively eliminated all the signs and symptoms of toxicity due to scorpion venom in Swiss albino mice. Still, it should not be used independently among humans.

Pages: 79 - 87
Abstract: The valued studies of alternative psoriasis treatment options are in a much higher need among the Scientific Community. This study aimed to evaluate the anti-psoriatic activity of ursolic acid cream in imiquimod-induced psoriasis in BALB/c mice. The creams containing ursolic acid, a pentacyclic triterpenoid at percentages of 0.1 and 0.2% were formulated. The pH, spreadability, physical characteristics and acute dermal irritation of the cream were assessed. Animals were grouped into five each having 6 animals. Clobetasol, a topical corticosteroid, was used as the standard. One group was used as control and four groups were treated with the formulated imiquimod cream while receiving treatment. Parameters such as skin inflammation severity, ear thickness, plasma level of interleukins (IL)-17, histology of the back of the skin and spleen weight were evaluated. Erythema and scales were scored on a daily basis with the 0.1 and 0.2% ursolic acid cream significantly ameliorating psoriatic-like symptoms in a manner comparable to clobetasol. Imiquimod-induced epidermal hyperplasia and inflammation were inhibited by topical application of ursolic acid as shown by the results of histopathology. Spleens of the positive control group were larger in comparison with the rest of the groups. BALB/c mice treated with ursolic acid creams exhibited a decrease in the plasma levels of cytokines IL-17 when compared to the positive control group. The result of this study provided an insight that topical application of ursolic acid can be a potential treatment for psoriasis

Authors: Sanjukta Rajhans, Himanshu Pandya, Sivakumar Prasanth Kumar, Kinjal Bhadresha, Deep Kumari Yadav, Rakesh Rawal, Hafsabanu Ansari, Ridham Dave, Gaurang Sindhav
Pages: 89 - 104
Abstract: Plant latex has been found to occur in more than 40 families and among them, Apocynaceae is one. Two plants of this family i.e., Cascabela thevetia (L.) Lippold and Plumeria alba L. had been chosen for the current experimental work. The aqueous and methanolic latex extracts were evaluated for their phytochemical constituents and cytotoxic activities. To determine the cytotoxic effects of the latex extracts, MTT [3-[4,5-dimethylthiazol-2-yl]-2,5- diphenyltetrazolium bromide] assay was performed by using cell lines A549 Human Lung Cancer and MCF-7 Human Breast Cancer. Further, for confirmation of the cytotoxic effects apoptosis assay was conducted. The richness of the latex extracts was determined by GC-MS and HPTLC methods. The preliminary phytochemical analysis of the latex extracts was conducted using GC-MS methodology. The presence of cardiac glycosides was analyzed using HighPerformance Thin Layer Chromatography. Here, Digoxin was used as the standard. Studies have revealed that Na+ K+-ATPase can serve as a powerful target for developing anticancer drugs and cardiac glycosides have exhibited anticancer effects via inhibition of the Na+ K+-ATPase. Hence, molecular docking studies were conducted in which 6KPX served as the target and the compounds evaluated by the NIST library in GC-MS served as the ligands. Further, Molecular docking studies confirmed the best among the compounds based on their RF score, binding affinity, and as a binder whether these compounds were good or bad. These methodologies altogether helped in evaluating the richness of the plant latex extracts, and the potent cytotoxic molecules present in them.

- Development and Validation of HPLC and UV Spectrophotometric Method for
the Quantification of Cinnamaldehyde in Cinnamon Bark Extract
Authors: Anjali Dhillon, Satish Sardana, Arti R. Thakkar
Pages: 111 - 119
Abstract: Cinnamaldehyde is the prime constituent of cinnamon bark and cassia oil. It is used as a flavoring agent. Numerous methods described the determination of cinnamaldehyde based on volumetric analysis, ultraviolet spectrometry, fluorimetry, thin layer chromatography, liquid chromatography and gas chromatography. The natural absorbance of cinnamaldehyde is at 286 nm which is used as a base for its determination through spectrophotometry or a suitable derivatizing reagent is used for its estimation. Most of these methods were simultaneous estimation methods and if non-simultaneous than not sensitive. Therefore, in the present study, sensitive HPLC and UV Spectrophotometric procedures have been established for the estimation of cinnamaldehyde in Cinnamon extract. The retention time of cinnamaldehyde was 7.21 minutes and absorption maxima come out to be 282 nm. 2.55 ± 0.003 mg/ml quantity of cinnamaldehyde was present in the cinnamon extract which is detected by UV Spectrophotometric method. Accuracy information appeared in the range that gives decent recovery figures for both processes. Sensitivity data furnished LOD 0.062 μg/ml and LOQ 0.19 μg/ml for HPLC and LOD 0.104 μg/ml and LOQ 0.312 μg/ml for UV Spectrophotometric method. The developed methods were found to be rugged and robust. The repeatability, Inter-day,and Intra-day precision of cinnamaldehyde provided RSD below 2% presenting the planned process to be extremely specific. Various factors to validate HPLC and UV Spectrophotometric methods of cinnamaldehyde were estimated and both methods show no significant difference. Developed procedures were statistically checked as per ICH guidelines.

- Microalgae: Nature’s Green System to Recycle Waste to Resource
Authors: Kanagam Nachiappan, Rajasekaran Chandrasekaran
Pages: 121 - 128
Abstract: Dairy wastewater management is a major concern for many milk-producing countries as it is a serious nuisance to the surroundings when disposed of untreated, increasing the organic load and foul smell. Microalgae remediation is an easy and cost-effective treatment to treat the effluent and simultaneously enhance a few agronomic traits. In this research, the phytoremediation technique was validated by treating dairy effluent using microalgal consortium and to study its impact on seed germination assay of Vigna mungo (Black gram). The results exhibited a significant increase in germination index, vigor index, and germination percentage when undiluted effluent was treated with microalgal consortium followed by other dilutions. Seedling growth was found maximum in 100% microalgal treated (TE100) undiluted effluent followed by 75% dilution (TE75), 50% dilution (TE50), 25% dilution (TE25), (TE0) treated effluent and compared with controls: water, effluent, fertilizer. So, we conclude that dairy effluent treated with suitable microalgae can be used directly for irrigation purposes to produce plants with high yield and significant biomass, indirectly making the industry a place of zero-waste discharge.

- Camphora Augments Humoral Mediated Immunity and Decreases Delayed type
Hypersensitivity in BALB/c Mice
Authors: Vara Prasad Saka, Narasimha Kumar G V, Abanti Goswami, Digvijay Verma, Pankaj Gupta
Pages: 157 - 167
Abstract: Background: Immunomodulation encompasses all therapeutic interventions aimed at modifying the immune response. The immune response augments are desirable to prevent infection in immunodeficiency states and fight established diseases. In this context, the present study investigated the effect of the homeopathic medicine, Camphora, in 6CH, 30CH, and 200CH potencies on immunomodulation in experimental animals. The acute oral toxicity study was also carried out in 6CH, 30CH, and 200CH potencies to determine the safe dose volume for the immunomodulatory study. Methodology: Acute oral toxicity studies of Camphora in 6CH, 30CH, and 200CH potencies were carried out as per OECD guideline 423 with slight modifications in Wistar albino rats. Humoral immunity, i.e., primary and secondary humoral responses, was assessed by measuring the hemagglutination titre of sheep red blood cells. Delayed-Type Hypersensitivity (DTH) was evaluated by measuring footpad thickness in BALB/c mice. Results: Camphora in 6CH, 30CH and 200CH potencies at a dose volume of 2000 µl/kg did not cause any mortality in the rats when administered as a single dose. Camphora in 6CH, 30CH and 200CH potencies showed augmented primary and secondary humoral responses against the SRBC antigen in BALB/c mice. However, the values were statistically non-significant except in the case of 6 CH potency (p<0.01), which showed statistically significant primary anti-SRBC antibodies. In the DTH assay, Camphora in 6CH, 30CH and 200CH potencies significantly decreased the paw volume ratio after 24 hrs of SRBC injection in the paw, thus insinuating its role in reducing cell-mediated immunity. Camphora in 6CH, 30CH and 200CH potencies also showed enhanced antibody titres and decreased paw volume compared to vehicle control, i.e. dispensing alcohol, suggesting that the effect was imminent because of Camphora. Conclusion: The study results indicate that Camphora in 6CH, 30CH, and 200 CH potencies is safe up to a dose volume of 2000 µl/kg when administered as a single dose, augments the primary and secondary humoral immunity, and decreases DTH in experimental animals. The current study’s findings suggest that Camphora might be useful as an immunomodulator in treating immune system disorders and infectious diseases and require further investigation to investigate its mechanism of action.

Pages: 169 - 183
Abstract: The fruits of Momordica charantia (Bitter Gourd) are well known for centuries as a natural remedy for the treatment of various ailments. In this study, we aimed to explore the metabolites present in both varieties of small and big bitter gourds and to explore the multitarget mechanism of M. charantia in antiviral infection by utilizing network pharmacology. The study design involves the identification of the compounds in both varieties of the bitter gourd by Agilent QTOFLC-MS/MS system, followed by screening for ADME to analyze the possible mechanism of action, disease association, protein-protein interactions and major pathways involved therein. Several Databases used were IMPAT, BindingDB, Swiss Target Prediction, STRING, DAVID, and KEGG databases, and algorithms were used to gather information. To visualize the network, Cytoscape 3.2.1 was used. As a result, a total of 22 and 27 compounds were detected from small and big bitter gourds respectively. . The molecules from M.charantia provide an antiviral response through the involvement of pathways like toll-like receptor pathway, PI3/AKT pathway, NF-kappa B signalling pathway, and cytokine-cytokine receptor interaction. Moreover, the core target genes termed ‘Hub Genes” were also identified through Cyto-hubba. The main mechanisms of M. charantia were acquired by investigating the enrichment of each cluster through functional association clustering analysis. Our results exposed the mechanism of M. charantia against viral infection by multi-component, multi-target, and multi-pathway study combinations.

Authors: Rupalben Jani, Shrey Patel
Pages: 191 - 204
Abstract: The objective of the current research study was to formulate and evaluate a sustained-release linezolid tablet using the natural antibacterial polymer Aegle marmelos. The natural gum of Aegle marmelos is becoming increasingly used in pharmaceutical formulations as a beneficial medication with excipients. Natural-based plant materials are biocompatible, free of side effects, biodegradable, and economic. Therefore, in order to maintain the drug releases from the matrix system, Aegle marmelos fruit gum as a natural polymer and HPMC grade (K100M) as a synthetic polymer were used in the formulation of the linezolid matrix tablet. The formulation of sustained-release matrix tablets included the wet granulation technique. The formulated matrix tablets were evaluated in terms of weight variation, hardness, diameter, physical appearance, friability, thickness, and in vitro drug release. Each formulation’s matrix tablet passed the required physical assessment tests. The formulation analyses of the tablets’ dissolution showed sustained releases of drugs for up to 10–12 hours. Additionally, several polymer combinations and fillers were used to improve drug release factors using the 32 factorial design approach, drug release kinetics were optimized, and the antibacterial study was evaluated.

- The Electro-Spun Sublingual Film Containing Curcumin Micelles
Authors: Bijal Prajapati, Pankita Rede, Chelsi Patel, Rahul Pujari, Abhay Dharamsi
Pages: 205 - 211
Abstract: Hydrophilic polymers D-tocopheryl polyethylene glycol succinate (TPGS-1000) and Poloxamer-188 were combined for the formulation of a sublingual film that aids in improving the oral bioavailability of the drug curcumin, which is not very soluble. For the formulation of micelles, the thin-film hydration technique was used and then electro-spun into a sublingual film that contained 13 % w/v PVP. Following that, prepared micelles and films were assessed and evaluated (particle size, PDI, zeta potential, %EE, pH studies, disintegration time, and in vitro drug release). According to the findings, the average particle size of the blended micelles was 230.2 nm. The ideal formulation of mixed micelles had a mean zeta potential and PDI of 20.73 mV and 0.258±0.038, respectively. Additionally, an entrapment efficiency of 82% was reached. In an aqueous medium, the film disintegrated in 40±10 seconds. Micelles were incorporated into the film without losing their integrity. Importantly, as compared to a pure drug, the films with micelles put on them showed improved bioavailability, high permeability and rapid absorption of the curcumin. Compared to the pure drug, the bioavailability of the films was increased by around 2.18 times due to the presence of mixed micelles loaded with curcumin. The results also showed that micelles-loaded sublingual films performed well in vitro for bioavailability improvement. In the end, it was found that films containing a mixture of poloxamer-188 and TPGS-1000 micelles would function effectively as carriers to boost curcumin’s bioavailability

- Simultaneous Determination of Tannic Acid and Eugenol in Newly Formulated
Churna of Tulsi and Parijat
Authors: Dr Hiral Dave, Krupali Shukla
Pages: 223 - 230
Abstract: Herbal formulations are widely used to treat a variety of diseases with the use of natural ingredients and have the additional advantage of negligible side effects. Looking towards the wide applicability of herbal formulations, a novel herbal formulation containing Tulsi and Parijat has been formulated and evaluated for different standardisation parameters. Tulsi and Parijat both possess multiple natural effects like antibacterial, antiviral and antipyretic properties along with wide applicability to treat different respiratory problems. Therefore, the combination of these two naturally available herbs can provide good immunomodulatory action for humans. Apart from the various phytoconstituents present in these two herbs, eugenol and tannic acid are found to have versatile effects. They are widely used to treat various common health issues like tonsillitis and various respiratory complaints like cough, cold and sour throat. A successful attempt has been made to develop the HPTLC method for the simultaneous determination of Tannic acid and Eugenol in pure and newly formulated churna containing Tulsi and Parijat as chief herbs. Tannic acid and eugenol mixtures get resolved by toluene:ethyl acetate:formic acid (5:3:2) with Rf of 0.849 ± 0.003 and 0.534 ± 0.009 respectively for tannic acid and eugenol. Linearity is observed within the range of 250–1500 ng/band for both eugenol and tannic acid. According to ICH Q2 R1 advice for analytical method validation, this designed technique has been effectively validated.

- Simultaneous Quantification of Piperine, Vasicine and Eugenol in Kabasura
Kudineer by HPTLC
Authors: M. K. Mohan Maruga Raja, Drashti C. Patel
Pages: 231 - 235
Abstract: Introduction: Kabasura kudineer is a polyherbal decoction of Siddha medical system (an Indian system of medicine), traditionally used to cure fever, colds, coughs, and respiratory ailments. Government of India had recommended kabasura kudineer as one among many preventive/treatment measures for COVID-19. Kabasura kudineer choornam is an admixed coarse powder of 15 herbs and its decoction is kabasura kudineer. The major chemical constituents present in the 15 herbs required to prepare the choornam are known but the chemical composition of the prepared kabasura kudineer (decoction) are unknown. Objective: As a part of the chemical investigation, piperine, vasicine and eugenol were chosen as marker compounds in kabasura kudineer based on their literature for exhibiting potent activity against upper and lower respiratory tract infections. The current work was planned to identify and quantify piperine, vasicine and eugenol simultaneously by TLC in kabasura kudineer. Methods: Silica gel 60F254 TLC plates were used for the study. The optimized mobile phase used was toluene: ethyl acetate: methanol: ammonia (5:9:3:0.5, v/v/v/v) and the densiometric scanning was done at 287 nm. Results: The Rf values of piperine, vasicine and eugenol were found to be 0.70, 0.32 and 0.82 respectively. Linearity range of piperine and vasicine was 500- 3000 ng spot-1 and it was 10- 60 ng spot-1 for eugenol. The amount of piperine, vasicine and eugenol in 100 mL of kabasura kudineer was found to be 0.03, 0.056 and 0.035% w/v respectively. The developed method was validated as per ICH guideline parameters. Conclusion: The current study shows that the developed TLC method is simple, precise, specific, robust and accurate. This method will also be useful to identify or quantity any polyherbal formulation containing piperine, vasicine and eugenol as chemical constituents.

- Structural Elucidation of Anti-Pseudomonas Component from Eucalyptus
Tereticornis
Authors: S. Badrunissa, Vinitha Ramanath Pai
Pages: 237 - 246
Abstract: Eucalyptus species is a well-known medicinal plant from ancient times with diverse biological functions, antimicrobial activity being one of them. This study attempts to isolate a secondary metabolite with antibacterial properties from ethanol extracts of Eucalyptus tereticornis leaf by antibacterial - against Pseudomonas aeruginosa - activity-guided procedure. Ethanol extract of the leaf powder was obtained by soxhlation and subjected to liquid-liquid extraction with organic solvents – ethyl acetate, n-hexane, n-butane, and chloroform. The active n-hexane and chloroform extracts were purified by column chromatography, and the components of the active eluant fraction were separated by Thin-layer chromatography (TLC). The purity of the antibacterial compound was checked by high performance liquid chromatography (HPLC), the molecular weight determined by Liquid chromatography-mass spectroscopy (LC-MS) and the structure elucidated and identified by nuclear magnetic resonance (NMR) and by Fourier transform infrared spectrometer (FTIR). TLC of n-hexane extract of liquid-liquid extraction showed a single spot with antibacterial activity. A single major peak was observed on HPLC, and LC-MS revealed that the compound is a formylated phloroglucinol component (FPC) with a molecular weight of 471.3. The NMR and FTIR analysis identified that the isolated compound is Macrocarpal A. This study reveals that the isolated relatively pure anti-Pseudomonas compound from the leaf extracts of E. tereticornis is Macrocarpal A, a flavanoid from FPC.

- Ayurvedic Management of Polypoidal Choroidal Vasculopathy (PCV) -A Case
Report
Authors: K. Shanti
Pages: 247 - 253
Abstract: Polypoidal Choroidal Vasculopathy (PCV), a subtype of neovascular Age-related Macular Degenerationn (AMD) is a disease characterized by persistent, recurrent serous leakage and hemorrhage in the macular area, mostly seen in the elderly population. While contemporary science offers anti Vasculo Endothelial Growth Factor (VEG-F) monotherapy and combination with Photodynamic Therapy (PDT), the outcomes of these remain doubtful. Repeated anti-VEG-F injections not only cause a financial and mental burden on the patients with no or very little visual outcome. Chronicity paves the way to complete loss of vision due to exudative retinal detachment. Symptoms like Raktavatdristi (to visualize things as if through a column of blood), Pashyatiaasyamanaasikam (unable to recognize the faces of people around) and aaviladarshanam (blurred vision) were suggestive of Raktaja Timira (an eye disease caused by Raktadosa) associated with Kaphadushti), according to Ayurveda. A 77-year-old male patient diagnosed with PCV sought Ayurvedic treatment after being advised to undergo anti-VEG-F therapy for the 3rd time in a row. His treatment comprised internal medicines consisting of Mahatiktakakashaya, Guduchyadikashaya, Chandraprabhavati and Avipathichurna; external treatments like Pratimarshanasya with Anu tailam and Gandusha with Triphalakashaya; Kriyakalpa (eye treatments) like Seka, Vidalaka, Aschotana and Anjana karma. At the end of 3 months of Ayurvedic treatment, his visual acuity in the right eye improved to 6/6, Optical Coherence Tomography (OCT) affirmed complete normalcy of the macula and Fundus examination confirmed the absence of neovascularization. Ayurvedic treatment is effective in reversing the process of neovascularization, thereby bringing about the marked visual outcome in PCV. Such patients should be encouraged to adopt Ayurvedic treatment instead of expensive and invasive treatment procedures like intra-vitreal injections even when the absolute effects of these remain doubtful.

- Evaluation of Memory and Cognition Enhancing Activity of Glycerrhiza
glabra Linn. Formulation Along with Yoga in Teenage (13-16 years)
Students.
Authors: Mrudul Chitrakar, Supriya Bhalerao, Vedvati Bhapkar, Vinay Pawar
Pages: 255 - 262
Abstract: Yashtimadhu (Glycyrrhiza glabra Linn), is one of the important neuro-nutrient herbs (Medhya Rasayana) mentioned in Ayurveda classics. Also, its usefulness on memory and cognition has been shown in many studies. Yoga, a part of rich Indian heritage has also shown promising results in memory enhancement of children & adults. Thus, a study was planned to assess efficacy of their combined schedule in teenage students. Glycyrrhiza glabra Linn. was converted into an herbal formulation ‘Yastimadhu Kalpa’ (YK) as per principles of Ayurveda pharmaceutics.The objective of this study was to evaluate effect of YK & Yoga schedule on memory and cognitive performance of teenage (13-16 years old) students. In this open-labelled, randomized, placebo-controlled study, 100 assenting healthy students between 13-16 years of age were enrolled and randomized into trial and control groups, after obtaining EC approval and parent consent. Those in the trial group received YK and Yoga, control group participants received placebo (Ragi malt) and Yoga. The YK and placebo were to be taken with cow milk in the morning. A 30-minute Yoga schedule was also taught to them. The duration of treatment was of 90 days. Effect on memory & cognition was assessed by cognitive ability and mental ability tests devised by Jnana-Prabodhini’s Institute of Psychology, Pune. These assessments were done on randomization visit (Day 0) and end of study visit (Day 90). Appropriate statistical tests applied to the data to obtain results.Both groups showed significant improvement in cognition and memory after 90 days treatment duration. However, YK group showed more significant improvement in cognition of figural classes and cognition of figural system in cognitive ability and memory of figural transformations, memory of symbolic transformations, total memory and mental ability among memory test parameters when compared to control group. Inclusion of Yoga schedule in both groups was found to be effective on improvement of memory & cognition.YK (formulation of Glycyrrhiza glabra Linn.) along with Yoga can be used in children to enhance their memory and cognition.

- Toxicity Status of Nano Powder of Stem Bark of Bauhinia Variegata Linn. on
Experimental Animals
Authors: Prachi Vishwakarma, Shailesh V. Deshpande, Snigdha Das Mandal
Pages: 263 - 270
Abstract: The assumption that medicinal plants are less toxic or cause fewer adverse effects due to their natural composition is debatable. Hence, this study was conducted to evaluate the safety and toxicity of Nano Kanchanara stem bark powder (NKSP) on liver function. The oral acute toxicity of NKSP was conducted in accordance with OECD Guidelines 423 and was carried out with six (6) female Wistar albino rats, divided into two groups of three rats each. Test rats were orally administered a single dose of 2000 mg/kg of NKSP and were observed for changes in behavior and mortality for the next 14 days, while the Control Group was given feed and water ad libitum. The data obtained from the oral acute toxicity study indicated that there were non-significant (P<1.000) decreases in body weight of rats in the treatment groups of NKSP at 2000 mg/kg. There were no elevations in specific liver function enzymes, whereas there were increases in serum SGOT, SGPT, and albumin levels. Plasma total proteins and globulin, total bilirubin and serum creatinine were within the normal range. Albeit, hydropic changes and steatosis in liver lesions at NKSP 2000 mg/kg. The study suggests that oral administration of NKSP is safer at dose levels less than 2000 mg/kg/day.

- High Dilutions of Homeopathic Drugs Interact with Human Serum Albumin as
Revealed by Electronic Spectroscopy
Authors: Prof. Nirmal Chandra Sukul, Dr. Raj Kumar Singh, Sumit Ghosh, Nivedita Pande, Anirban Sukul
Pages: 271 - 274
Abstract: Homeopathy uses drugs in extreme dilutions that are mostly devoid of the original drug molecules. Drug-induced water structures are thought to be responsible for their therapeutic effect. We have already observed that homeopathic potencies first interact with serum albumin, which is present in the oral mucosa. In this experimental study, we have shown that the homeopathic potencies of three drugs, Bryonia alba (Br), Rhux toxicodendron (Rt), and Thuja occidentalis (Th), initiate their action on Human Serum Albumin (HSA). The potency-HSA complexation has been observed by electronic spectroscopy. The control, HSA plus water, shows only one peak at 216 nm, but the potencies plus HSA show two peaks, one at 205 nm and another around 265 nm. The first peak is due to the peptide bond. The first peak in the control shows a marked red shift. The second peak at higher wavelength is due to the aromatic amino acids. The first peak with the potencies shows a marked blue shift, possibly due to a change induced by the potencies on the peptide bond. Unlike water control the potencies interact with aromatic amino acids. It is evident that the complexes made up of HSA and potency are different from those of the control. This means that homeopathic potencies are not ordinary water. It is concluded that water control interacting with HSA shows a single peak in UV-spectra at lower wavelength, but homeopathic potencies show one additional peak at a higher wavelength besides the peak at the lower wave length. HDs can produce effects on aromatic amino acids. The mother tinctures and their HDs show marked differences from each other in their electronic spectra.

- In vitro Evaluation of Antibiofilm Activity of Methanolic Leaf Extract of
Azadirachta indica on Cariogenic Streptococcus mutans
Authors: Deepesh Dinesh, IMRAN KHALID, Sivakumar Vijayaraghavalu, Saifulla Khan M, Nikesh V V
Pages: 275 - 281
Abstract: Dental caries is a biofilm-dependent disease, and Streptococcus mutans is the primary etiological agent involved in the initiation of the disease. The extensive use of a limited range of antimicrobial drugs in dentistry has led to the development of drug-resistant bacteria. There is an increasing need to find new alternatives against drug-resistant bacteria. Globally, there is a continuous effort towards identifying natural anti-caries agents for the prevention and better management of caries. The objective of the present study was to evaluate the antibiofilm potential of Azadirachta indica leaf methanolic (ALM) extract against S. mutans biofilm. The study employed a standard reference strain of S. mutans MTCC 497, for in vitro standardisation of biofilm by microtiter plate assay. The antibiofilm activity of the ALM extract was evaluated against the S. mutans strain, and the same was confirmed by light and scanning electron microscopy (SEM). The in vitro biofilm standardisation results demonstrated that 50 µl/ml of S. mutans inoculum concentration exhibited a much superior biofilm formation than the other concentrations employed. Light microscopy and SEM images revealed that ALM extract at 100 mg/ml concentration significantly inhibited the S. mutans biofilm. To conclude, the study reports that the A. indica leaf extract is a potential source to inhibit the S. mutans biofilm. Further studies are warranted to identify the phytochemicals responsible for the antibiofilm activity of ALM extract against S. mutans biofilm that aid in the design of natural anti-caries products.
