  • EPHROPROTECTIVE EFFECTS OF ETHANOLIC EXTRACT OF Solanum Melongena AGAINST
           CARBONTETRACHLORIDE (CCL4) INDUCED TOXICITY IN RATS

    • Authors: John Adanu Joshua, Jibrin Noah Akoji, Irozuoke Clare Chinenye
      Abstract: Nephroprotective effects of ethanolic extract of solanum melongena against carbontetrachloride (ccl4) induced toxicity in rats was studied. Serum urea, Na+K, chloride, Bicarbonaate were determined using Diacetyl monoxime method, Flame photometery method, Shales and Scale method and Trimetric method. The result for changes in body weight following oral administration of the extract (Solanum melongena) for induced toxicity on rats ranged; 157-127mg, 0.39 – 10.28mg, 5.59-5.08mg, 3.44-13.64mg, 0.85-3.90mg and 6.40-1.65mg for the initial, 3days, 6days, 9days, 12days and 15 days respectively. Effects of oral administration of Solanum melongena on Indices of renal function and relative organ weight in CCl4 induced toxicity in rats indicates that creatinine(µmol/l) has the highest value of 143.50±13.86 in group5 and the lowest value of 36.80±4.59 in group1. Urea (mmol/l) has the highest value of 8.34±0.86 and the lowest value of 6.38±0.68. Sodium (mmol/l), Potassium (mmol/l), chloride (mmol/l), Bicarbonate (mmol/l) and Relative kidney have the highest values of 125.50±0.77, 5.46±71.00, 102.20±3.74, 21.00±0.44 and 0.91±0.07 respectively.  Administration of carbon tetrachloride has lead to a slight but insignificant increase in the serum level of creatinine, sodium, potassium, chloride and bicarbonate. This indicates that the carbon tetrachloride might not have caused significant damage to the kidneys. Oral administration of ethanolic extract of Solanum melongena for fourteen days increased significantly the serum creatinine levels. Oral administration of the extract alone also led to similar increase in the creatinine level suggesting possible nephrotoxicity of the extract. Keywords: key words, nephrotoxicity, ethanolic, toxicity, carbontetrachloride

  • Investigation of Laboratory and Chemical Safety in Wolaita Sodo
           University, Ethiopia

    • Authors: Mathewos Anza
      Abstract: The present work aims at investigating laboratory and chemical safety in the case of Wolaita Sodo University. It provides the information to policy makers’ insights to establish laboratory and chemical safety in the developing countries, similarly in Ethiopia. The sample for the study comprised 39 respondents; 30 instructors and 9 laboratory technical assistances from chemistry and biology departments of Wolaita Sodo University. Data were collected using structured questionnaires and observation checklist. The collected data were analyzed using qualitative and quantitative analysis. The results revealed that the need for corrective action to establish functional and safe chemical laboratories in the institution; and the majority of respondents agree with the statements, share the skills that students and other workers need if they are to handle chemicals safely, and hazard warning labels are properly used (94.9% ); care you and environments from hazard chemical misuses(92.3%); follow all of the safety protocols for the protection of themselves as well as others and reporting to the concerning bodies happened accidents immediately (89.7%); make clean and hygiene workplaces(82.1%); properly use personal protective equipment, appropriately sort chemicals in their compatibility, and take care waste management’s (76.9%) are their responsibility and accountability. Furthermore, the  major factors that influence establishment of safe and functional chemical laboratory is Unplanned / low quality order and purchase of chemicals and instruments; lack of trained personnel; the cost or limited availability of safety equipment; lack of companies to discard dangerous wastes from laboratories; limitation of budgets; lack of proper drainage system in the buildings where the lab rooms are situated; absence of continuous water flow in the labs; less attention of top managements to laboratory and chemical safety; large size of students in practical classes in the labs; and inappropriate infrastructure to laboratory rooms. From this result it was concluded that a successful chemical safety program requires a daily commitment from everyone in the institution; and finally recommendations were forwarded based on the major finding in order to improve functional and safe chemical laboratory in the institutions. Keywords: Laboratory and Chemical Safety, Waste Management, Chemical Labeling

  • Study on the Bioaccumulation of Heavy Metals in Fish Samples and
           Physico-Chemical Analysis of Water from Lake Hawassa, Ethiopia

    • Authors: Ermias Haile
      Abstract: Samples were collected from Lake Hawassa, from six selected sampling sites. The measured physico-chemical parameters in lake water ranged pH(7.70-8.69), TDS(437-495 mg/L), EC(0.729-0.825 mS/cm), DO(6.2-14.6 mg/L), Temp.(20.7-23.4 0C), Turb.(6.3-26.7 NTU), SO42-(25-16), Cl-(42-23), F-(17.4-5.36), NO3-N (2.38-11.79), PO43-(0.81-1.55), COD(219-1216), and BOD5(104-590) mg/L. The concentration of detected metals in water samples were in the range Cu(0.226-0.117), Mn(0.166-0.068), Zn(0.253-0.145), Mg(35.91–14.27), Ca(57.11-35.23), Na(87.49-87.49) and K(73.02-34.26) in mg/L. According to stream and potable waters standard recommendation, the maximum value of BOD5, COD, PO43- and F- were above the acceptable range. The detectable metal concentration in water samples analyzed were Na>Ca>K>Mg>Zn>Cu>Mn. The concentration of Mn in the present study was above USEPA but below WHO guideline. The dendrogram figure shows that metal parameter of water samples at S1 the pollution level is higher than the other sites. All the transfer factors of water were greater than 1 in fish muscle. Keywords: Hierarchical cluster analysis, metal, physico-chemical, transfer factor.

  • Ions Traces Substitution in Stoichiometric Calcium-Hydroxyapatite:
           Structural Analysis by Rietveld Refinement

    • Authors: M. Elassfouri, B. El ouatli, F. Abida, M. Jamil, A. Kheribech, Z. Hatim
      Abstract: Impact of trace ions as Mg2+, Na+, Sr2+, SO42-, and CO32- on stoichiometric hydroxyapatite (Ca10(PO4)6(OH)2) crystal structure is investigated. The first four ions are brought by the raw material while the carbonate group is due to contamination by air. The powders were prepared, under industrial conditions, at 22°C from aqueous solutions by reaction between the calcium hydroxide and orthophosphoric acid at pH from 7 to 7.5. Two samples of hydroxyapatite powder, which differ by the content of ions trace, calcined at 1100°C have been investigated by X-ray powder patterns fitting methods. Results showed that in the absence of ion traces, the partial replacement of PO43- by CO32- groups leads to the - relaxation of the lattice by creation of vacant calcium (Ca1 and Ca2) sites, - reduction of the cell parameters, and new lattice rearrangement with lower PO4 distortion index, (Dind = 0.488) compared to the calculated theoretical value (Dind=3.079). For trace ions incorporated hydroxyapatite sample, the presence of traces cation favors the incorporation of carbonate ions. Coupled substitution on Ca2 and P position affect neither theoretical structure nor thermal stability of the hydroxyapatite but causes vacancies creation in calcium (Ca1) and oxygen (O1 and O3) sites. This structural change leads to a slight lattice distortion (Dind=3.204). Composition and microstructure of analyzed materials appear very promising for biological applications. Keywords: Biomaterials, Calcium-hydroxyapatite, Traces ions, Crystalline structure.
