  • Morphological Characteristics of the Oropharyngeal Cavity (Tongue, Palate
           and Laryngeal Entrance) in the Eurasian Coot (Fulica atra, Linnaeus, 1758)
           
    • Authors: M. M. A. Abumandour; N. E. R. El-Bakary
      Abstract: The present study represents the first definitive anatomical description of the oropharyngeal cavity of the coot Fulica atra. For this purpose, the organs of six birds were prepared to examine grossly and by SEM and stereomicroscope. The oval lingual apex had multiple overlapping branched acicular processes on its anterior and lateral border. The lingual apex and body had multiple caudally directed filiform-like papillae. By stereomicroscopy, the lingual root had a characteristic appearance and consisted of four parts. The openings of the anterior glands were present on the dorsal lingual surface of the body, while the projected papillae with wide openings of the posterior glands were present on the dorsal surface of lingual root. There was a row of caudally directed pharyngeal papillae at the caudal border of the laryngeal mound. Grossly, the pharyngeal papillae arrangement took a W-shape, while by stereomicroscopy was observed to be heart shape. The palate was divided into two regions: a small rostral non-papillary and a large caudal papillary region, but the rostral region was characterized by the presence of three longitudinal ridges. The papillary crest had two paramedian longitudinal papillary rows, which continued caudally until the beginning of the third median row. The freely distributed papillae took a caudolateral direction, while the papillae encircling the rostral part of choanal cleft took a caudomedial direction. There was a transverse papillary row between the two parts of choanal cleft. There was a transverse papillary row between the caudal border of the infundibular cleft and oesophagus.

  • Testicular Structure and Seminal Pathway in the Yellowtail Tetra Astyanax
           altiparanae (Characiforms: Characidae)
    • Authors: D. H. Siqueira-Silva; A. P. Dos Santos-Silva, C. Bashiyo-Silva, M. S. Rodrigues, C. A. Vicentini, A. Ninhaus-Silveira, R. Veríssimo-Silveira
      Abstract: This study aimed to describe testicular and its main ducts structure in the yellowtail tetra Astyanax altiparanae, contributing to the knowledge of the region in which semen is produced, storage and released, focusing mainly on the dynamic of germinal epithelium and Sertoli cells during germ cell maturation. Ten sexually mature male A. altiparanae had their testes processed according to the routine protocols to optical microscopy. Moreover, spermatic ducts and tubular compartment of the testes of three specimens were perfused with vinyl resin for gross anatomy and scanning electron microscopy. Astyanax altiparanae testes are paired organs, separated for most of their extension, joining posteriorly in a spermatic duct formed by a squamous simple epithelium. Seminiferous compartment presents anastomosing tubular type organisation, and spermatogonia spread along its extent. Spermatogenesis is of cystic type, and there is no main testicular duct. Spermatogenesis develops in ‘waves’, from posterior to anterior part of the gonad. Thus, while sperm is storage posteriorly, spermatogenesis keeps maturing germ cells anteriorly, making the germinal epithelium very dynamic, holding Sertoli cells that change their function as a cystic envelope to produce secretions of the seminal fluid and store sperm. Such kind of development is thought to be responsible by the high prolificacy of this species.

  • Histological Characteristics of the Tracheobronchial Tree of the Least
           Shrew (Cryptotis Parva)
    • Authors: F. Arodaki; W. Khamas, N. Darmani, M. Al-Tikriti
      Abstract: The least shrew (Cryptotis parva) is a small vomit-competent insectivorous species which has recently been introduced as an emesis animal model in the laboratory. In this study, the respiratory system of the least shrew was examined and compared with the well-established larger species routinely used in the laboratory. Five least shrews (4–5 g body weight, 45–60 days old) were used. Standard histological procedures were followed for light microscopic examination. The lining epithelium of the trachea was found to be pseudostratified ciliated columnar (PSCC). Three types of cells were easily identified, basal and ciliated as well as few goblet cells interspersed among the ciliated cells and they were not clearly recognizable. A few tracheal seromucous glands were located at the free end of the C-shaped cartilaginous rings. The cartilaginous rings are replaced by smooth muscle cells before the bronchi enter into the lung. The lining epithelium of tracheobronchial tree gradually changes into simple cuboidal epithelium that lacks goblet cells. However, the division of the tracheobronchial tree is similar to other mammalian species. On the other hand, the principal bronchus lacks cartilaginous plaques as it becomes intrapulmonary bronchus. The wall of the bronchi is supported by thick layers of spirally arranged smooth muscles. Two types of cells were readily recognizable: basal and ciliated cells, with rarely observed goblet cells. In addition, the PSCC epithelium changes into simple cuboidal much earlier in the bronchial division relative to other species.

  • Leptin Immunohistochemical Staining in the Porcine Ovary
    • Authors: D. Phoophitphong; S. Srisuwatanasagul, P. Tummaruk
      Abstract: This study aimed to investigate leptin immuno-staining of the porcine ovary in different reproductive stages. Ovaries from 21 gilts were collected from slaughterhouses. The ovarian tissue sections were incubated with a polyclonal anti-leptin as a primary antibody. The immuno-staining in ovarian tissue compartments was calculated using imaging software. Leptin immuno-staining was found in primordial, primary, preantral and antral follicles. Leptin immuno-staining was expressed in the oocyte and granulosa and theca interna layers in both preantral and antral follicles. In the corpora lutea, leptin immuno-staining was found in the cytoplasm of the luteal cells. The leptin immuno-staining in the granulosa cell layer of preantral follicles did not differ compared to antral follicles (90.7 and 91.3%, respectively, P > 0.05). However, the leptin immuno-staining in the theca interna layer of preantral follicles was lower than antral follicles (49.4 and 74.3%, respectively, P  0.05). However, the leptin immuno-staining in the theca interna layer of follicular phase was greater than that in the luteal phase (72.7 and 51.0%, respectively, P

  • Presence of ganglia and telocytes in proximity to myocardial sleeve tissue
           in the porcine pulmonary veins wall
    • Authors: T. Vandecasteele; P. Cornillie, K. Vandevelde, A. Logothetidou, L. Couck, G. Loon, W. Van den Broeck
      Abstract: Ganglia and telocytes were identified inside the porcine pulmonary veins wall near myocardial sleeve tissue at the atriopulmonary junction. These structures are reported to play a role in the initiation of pulses from outside the heart, which potentially can cause cardiac conduction disorders such as atrial fibrillation. In-depth knowledge on the fine structure of the pulmonary vein wall is a pre-requisite to better understand the underlying pathophysiology of atrial fibrillation and the origin and conduction of ectopic pulses. The importance of pulmonary vein myocardial sleeves as triggering foci for atrial fibrillation has been shown in human patients. In this context, the fine structure of the pulmonary vein wall was investigated qualitatively by light and transmission electron microscopy in the pig, which is a frequently used animal model for development of new treatment strategies. Additionally, intra and extramural ganglia, containing telocytes that create a network near the neurone cell bodies, were identified in pigs. Detailed illustration of the distribution and organization of tissues and cell types, potentially involved in the origin and propagation of ectopic stimuli originating from the pulmonary veins, might lead to a better insight on the actual composition of the tissues affected by ablation as studied in pigs.

  • New Insights into the Neural Differentiation Potential of Canine Adipose
           Tissue-Derived Mesenchymal Stem Cells
    • Authors: D. Blecker; M. I. Elashry, M. Heimann, S. Wenisch, S. Arnhold
      Abstract: Adipose tissue-derived stem cells (ASCs) can be obtained from different adipose tissue sources within the body. It is an abundant cell pool, easily accessible, suitable for cultivation and expansion in vitro and preparation for therapeutic approaches. Amongst these therapeutic approaches are tissue engineering and nervous system disorders such as spinal cord injuries. For such treatment, ASCs have to be reliably differentiated in to the neuronal direction. Therefore, we investigated the neural differentiation potential of ASCs using protocols with neurogenic inductors such as valproic acid and forskolin, while dog brain tissue served as control. Morphological changes could already be noticed 1 h after neuronal induction. Gene expression analysis revealed that the neuronal markers nestin and βIII-tubulin as well as MAP2 were expressed after induction of neuronal differentiation. Additionally, the expression of the neurotrophic factors NGF, BDNF and GDNF was determined. Some of the neuronal markers and neurotrophic factors were already expressed in undifferentiated cells. Our findings point out that ASCs can reliably be differentiated into the neuronal lineage; therefore, these cells are a suitable cell source for cell transplantation in disorders of the central nervous system. Follow-up studies would show the clinical benefit of these cells after transplantation.

    • Authors: T. Pitakarnnop; K. Buddhachat, T. Euppayo, W. Kriangwanich, K. Nganvongpanit
      Abstract: This study demonstrates sexual dimorphism of feline bones, based on a morphometric analysis of 38 dried feline skulls and pelvic bones (20 males, 18 females). A total of 44 parameters (skull = 12, mandible = 10, pelvis = 22) were measured using a digital vernier calliper. In morphological observation of these bones, there were three hallmarks indicating a remarkable difference between sexes: the coronoid process of the mandible (accuracy rate = 88.2%); and the os coxae – caudal ventral iliac spine (accuracy rate = 94.4%), and the angle of the ischiatic arch (accuracy rate = 74.3%). In addition, based on morphometric characteristics, six parameters were found to be significantly different (P

  • Gross Measurements of the Digestive Tract and Visceral Organs of Addax
           Antelope (Addax nasomaculatus) Following a Concentrate or Forage Feeding
           Regime
    • Authors: S. A. Tahas; O. Martin Jurado, S. Hammer, A. Arif, S. Reese, J.-M. Hatt, M. Clauss
      Abstract: Differences in macroscopic measurements of the gastrointestinal tract have been hypothesized to correlate with the browser–grazer continuum in the natural diet of ruminants. However, to what extent these characteristics represent species-specific traits, or respond to the actually ingested diet, remains to be investigated. Twelve surplus addax antelope (Addax nasomaculatus) were divided into two groups and fed, for 3 months, either their usual diet, consisting of a concentrate feed with a limited amount of hay, or a diet of unlimited hay only. After culling, macroscopic measurements were compared between groups. The macroscopic anatomy of the addax showed many characteristics considered typical for grazing or ‘cattle-type’ ruminants. While both diet groups had mesenteric, pericardial and perirenal adipose tissue, these depots were subjectively more pronounced in concentrate-fed animals. Hay-fed animals had significantly heavier filled forestomach compartments, with corresponding significantly longer linear measurements. Masseter muscles and the surface of first-order omasal leaves were significantly more prominent in hay-fed animals, reflecting possible adaptations to overcome resistance of grass forage and to reabsorb fluid from increased rumination, but differences were not as distinct as reported between ‘cattle-type’ and ‘moose-type’ ruminants. Some measurements such as reticular crests and empty foregut mass remained stable between groups, indicating possibly genetically pre-defined characteristics less prone to change in adult life. The results emphasize the adaptability of ruminant digestive tract anatomy in adult animals even after a short period of time, but also suggest limits to this adaptability that reveals a species-specific anatomy regardless of the diet actually consumed.

  • A Morphological and Stereological Study on Cervical Segment of Spinal Cord
           of Quails
    • Authors: G. Cakmak; Z. Soyguder, M. C. Ragbetli
      Abstract: In this study, volume densities of white and grey matters of cervical segments of spinal cords of quail were investigated stereologically. In both sexes, mature, six quails were used as material of this study. All animals were fixed by perfusing in 10% buffered formalin. Tissue specimens were obtained from cervical spinal cords. These tissue specimens were cut every fiftieth section at 5 μm thickness by a microtome. And mean six or seven sections were examined from every block by this method at microscope. After that, these sections were stained by haematoxylin eosin and photographed. Densities of volumes of all tissues of cervical segments of whole spinal cords and white and grey matters were calculated with principle of Cavalieri. As a result, total volume of spinal cord, volumes of white and grey matters of cervical segment and volume rates of white and grey matters were calculated.

  • Ultrastructure of Cell Organelles in Pre-implantation Embryos from Cows
           with Different Body Condition Score
    • Authors: L. Olexiková; J. Pivko, A. V. Makarevich, E. Kubovičová, A. Ostró, J. Živčák, P. Chrenek
      Abstract: Morphology of important cell organelles (mitochondria, lipid droplets, vacuoles, inclusion bodies and apoptotic bodies) in embryos derived from cows with different body condition score (BCS) was analysed by transmission electron microscopy (TEM). Embryos were recovered on 7th day after the insemination by a standard non-surgical flushing of the uterine horns from superovulated Holstein Friesian cows with BCS 2, 3, 4 and 5. Thereafter, the good quality blastocysts were processed for TEM. The electronograms were evaluated by stereological analysis. The relative volume of lipid droplets in BCS4 and BCS5 embryos increased significantly (18.53 and 22.40%) when compared to BCS3 embryos (5.46%). In the embryos from the BCS4 or BCS5 cows, we observed different morphological patterns of mitochondria, as well as the mitochondria containing vacuoles. BCS4 and BCS5 embryo cell nuclei showed the structure typical for low transcription activity (none or very few reticular nucleoli); also dilated inter-cellular spaces were often observed in these embryos. In conclusion, differences in the ultrastructural morphology of embryos from over-conditioned cows (BCS4 and BCS5), particularly the higher lipid content in the cytoplasm, can be a marker of their low quality, and this fact can be a contributing factor to subfertility in over-conditioned cows.

      Abstract: The objective of this study was to examine the influence of the size, age and sex of the horse on the size of the pituitary gland and determine the possibility of using the pituitary gland height-to-brain area ratio (P:B ratio) to allow comparison of different sized and aged horses. Thirty-two horses without pituitary pars inter-media dysfunction that underwent a contrast-enhanced computed tomographic (CT) examination were included in a cross-sectional study. On the CT images, the pituitary gland height was measured and the P:B ratio was calculated. These measurements were correlated to the size, age and sex of the horses. The pituitary gland height was significantly associated with the size (P

  • Structure and Innervation of the Equine Supraspinous and Interspinous
           Ligaments
    • Authors: A. Ehrle; L. Ressel, E. Ricci, E. R. Singer
      Abstract: Pain related to the osseous thoracolumbar spine is common in the equine athlete, with minimal information available regarding soft tissue pathology. The aims of this study were to describe the anatomy of the equine SSL and ISL (supraspinous and interspinous ligaments) in detail and to assess the innervation of the ligaments and their myofascial attachments including the thoracolumbar fascia. Ten equine thoracolumbar spines (T15-L1) were dissected to define structure and anatomy of the SSL, ISL and adjacent myofascial attachments. Morphological evaluation included histology, electron microscopy and immunohistochemistry (S100 and Substance P) of the SSL, ISL, adjacent fascial attachments, connective tissue and musculature. The anatomical study demonstrated that the SSL and ISL tissues merge with the adjacent myofascia. The ISL has a crossing fibre arrangement consisting of four ligamentous layers with adipose tissue axially. A high proportion of single nerve fibres were detected in the SSL (mean = 2.08 fibres/mm2) and ISL (mean = 0.75 fibres/mm2), with the larger nerves located between the ligamentous and muscular tissue. The oblique crossing arrangement of the fibres of the ISL likely functions to resist distractive and rotational forces, therefore stabilizing the equine thoracolumbar spine. The dense sensory innervation within the SSL and ISL could explain the severe pain experienced by some horses with impinging dorsal spinous processes. Documentation of the nervous supply of the soft tissues associated with the dorsal spinous processes is a key step towards improving our understanding of equine back pain.

  • Morphological Study of the Persian Leopard (Panthera pardus saxicolor)
           Tongue
    • Authors: J. Sadeghinezhad; M. T. Sheibani, I. Memarian, R. Chiocchetti
      Abstract: This study described the morphological features of the Persian leopard (Panthera pardus saxicolor) tongue using light and scanning electron microscopy techniques. The keratinized filiform papillae were distributed all over the entire dorsal surface of the tongue and contained small processes. They were changed into a cylindrical shape in the body and conical shape in the root. The fungiform papillae were found on the apex and margin of the tongue. Few taste pores were observed on the dorsal surface of each papilla. The foliate papillae on the margins of the tongue were composed of several laminae and epithelial fissures. Taste buds were not seen within the non-keratinized epithelium. The vallate papillae were six in total and arranged in a “V” shape just rostral to the root. Each papilla was surrounded by a groove and pad. Taste buds were seen within their lateral walls. Lyssa was visible on the ventral surface of the tongue tip and was found as cartilaginous tissue surrounded by thin connective tissue fibres. The core of the tongue was composed of lingual glands, skeletal muscle and connective tissue. These glands were confined to the posterior portion of the tongue and were composed of many serous cells and a few mucous cells. The results of this study contributed to the knowledge of the morphological characteristics of the tongue of wild mammals and provided data for the comparison with other mammals.

  • A Macro-Anatomical Investigation of the Some Skull Bones of Nehring's
           Blind Mole Rats (Spalacidae: Nannospalax nehringi)
    • Authors: Ş. Ketani; M. Kilinç, S. Erdoğan, A. Kaya, Y. Coşkun
      Abstract: This study was aimed to demonstrate the specific anatomical features of the skull bones of Nehring's blind mole rats. Eight skulls, belonging to animals of both sexes, were used. The occipital squama contributed to the formation of the caudal portion of the skull roof. The foramen magnum was quite large. The external occipital crest was present only in the males. The parietal bones formed the middle portion of the skull roof together with the well-developed inter-parietal bones. The zygomatic process of the temporal bone formed the zygomatic arch by extending to the temporal process of the zygomatic bone. The zygomatic process of the frontal bone and the frontal process of the zygomatic bone laterally bordered the orbit. There was a single septal process of the nasal bone. Each ramus of the mandibula had four processes. The mandibular ramus had an angular process on its caudal rim, which extended dorsolaterally. The dorsal free end of the mandibular ramus possessed a coronoid process. In the back, there were two other processes, situated medially and laterally. The medially situated process was referred to as a condylar process, and the laterally situated process was referred to as an alveolar process. The alveolar process detected on the mandibular ramus has not been reported in any rodent species, other than those of the family Spalacidae. Blind mole rats can be a real eye-opener for evolutionary science. The burrowing rodents are key to answering a controversial question about how new species arise.

  • Morphometric Changes in Polish Konik Mares After Nearly a Hundred Years of
           the Breed's Existence
    • Authors: E. Pasicka; K. Tarnawski, A. Chrószcz, H. Geringer de Oedenberg
      Abstract: The study was carried out on 126 mares of the Polish Konik horse breed. Mares were bred under a stable system housing and they came from five leading conservation breeding centres. The mares were divided into three age groups: 3–5 years old, 6–9 years old and over 10 years old. Each animal was characterized using 40 morphometric measurements. Discriminant analysis proved the exterior differences of mares in terms of the analysed metric values. It was concluded that the morphotype of modern Polish Konik mares is statistically significantly influenced by the following traits: neck ventral length, forearm circumference, distance between the vascular notch (incisura vasorum facialium) and the oral angle (angulus oris), distance between the margo coronalis ungulae and the margo solearis ungulae of the thoracic limb, thorax circumference and pelvis width. Conformation traits of the studied Polish Konik mares show multidirectional changes, prevailingly an upward trend in the mean values. However, shoulder height turned out to be definitely the least modified trait. Results obtained in the research presented herein may be a confirmation of progressing exterior transformations, which have been identified in the new generation, namely in the youngest group of mares of this breed.
