The histological and morphometric differences in some parts of the gastrointestinal tracts of rat, bat and pangolin have been well established. This investigation aims at comparatively elucidating any adaptational changes the ileum of the three mammals must have adopted to meet its dietary requirements and also cope with their morphological differences. The investigation was carried out using ten rats, ten bats and ten pangolins of both sexes. The animals were slightly anaesthetized under chloroform inhalation. The intestines were harvested and the ileum excised and fixed in 10% formol saline. The tissues were processed for light microscopic study. The following stains were employed: Haematoxylin and eosin (H &amp;amp; E), Van Gieson and Verhoeff's...

A Comparative Histomorphometric Study of the Stomach of Rat (Rattus norvegicus), Bat (Eidolon helvum) and Pangolin (Manis tricuspis) in Relation to Diet

This study verified the comparative histomorphometric adaptations in the stomach of rat, bat and pangolin in relation to diet. Ten rats, ten bats and ten pangolins of both sexes were used for this investigation. The animals were sacrificed after slight anesthesia under chloroform inhalation. The stomach were excised, fixed in 10% formol saline and processed for light microscopic study. Stained slides were also subjected to morphometric analysis at a magnification of 400x. The results revealed that the cellular diameter/ density of parietal and zymogenic cells are significantly different in the three mammals (p&lt;0.05) with the exception of the diameter of the zymogenic cells in pangolin which was not statistically significant (p&gt;0.05) when compared...

Diabetes mellitus (DM) is a serious metabolic disorder with micro and macro-vascular complications that result in a significant morbidity and mortality. The present study investigated the effects of Momordica charantia (M. charantia) on histological changes of the aorta and pulmonary trunk in streptozotocin-induced diabetic Wistar rats. Forty healthy adult Wistar rats of both sexes were randomly assigned into five groups A, B, C, D and E of eight rats each. Group A were the control (normal rats); B were the experimentally-induced diabetic rats; C were diabetic rats treated with methanolic extracts of M. charantia for two weeks (withdrawal group); D were diabetic rats treated with methanolic extracts of M. charantia for four weeks. E was diabetic rats...

Lumbar vertebral dimensions provide vital clinical information of immense diagnostic benefits to medical experts. The present study provides data for lumbar vertebral dimensions of a cohort of specimens of South African females and males. Measurements were obtained from lumbar vertebrae from the osteological collections in the Discipline of Clinical Anatomy, Nelson Mandela School of Medicine using a digital caliper. The antero-posterior body diameter (APD), interpedicular distance (IPD), midsagittal diameter (MSD) and pedicle length (PL) were measured while ratio of MSD to APD was calculated. Results showed gradual increase from L1 to L5 for mean APD and IPD, and a decrease for mean PL from L1 to L5. Mean MSD was observed to present a "U" curve pattern...

Ultrastructural and Immunohistochemical Effects of Aqueous Leave Extract of Xylopia aethiopica on the Stomach in Streptozotocin-Induced Diabetic Rats
Provedor de dados: 77
Autores: Ofusori,D. A; Komolafe,O. A; Adewole,O. S; Arayombo,B. E; Margolis,D; Naicker,T.
Gastrointestinal pathology in diabetic patients has become a source of concern in recent times. The aim of this study was to investigate the ultrastructural and immunohistochemical effects of aqueous leaf extract of Xylopia aethiopica on the stomach in streptozotocin-induced diabetic rats. This study was conducted using thirty adult Wistar rats. The animals were divided into three groups (n= 10). Group A was the control animals (administered with equivalent volume of citrate buffer), group B was diabetic animals induced by a single intraperitoneal injection of streptozotocin dissolved in citrate buffer (65 mg/kg) and group C was diabetic animals treated with 200 mg/kg body weight of aqueous leave extract of X. aethiopica for twenty five days. At the...

Comparison of Antioxidant Effects of Kolaviron and Vitamin C Interventions on Testicular Structures Following Nevirapine Administration in Sprague-Dawley Rats

Testicular toxicity has been implicated in highly active anti-retroviral therapy (HAART) treatment. Hence there is need to identify an effective antioxidant product that can alleviate testicular necrosis due to HAART administration. Forty eight adult male Sprague-Dawley rats were used in this study. The animals were divided into eight (8) groups: A-H (n= 6). Group A animals received normal saline as the control; Group B was given Nevirapine (Nv); Group C was given Kolaviron (Kv); Group D was given vitamin C; Group E was given Nv and Kv; Group F was given Nv and Vitamin C; Group G was given Nv for 56 d and Kv for 28 d serving as a withdrawal group; Group H was given corn oil. Nv, Kv and Vit. C were given at 1.54, 200 and 250 (mg·kg)/bw respectively while...

Autores: Ofusori,D. A; Caxton-Martins,E. A; Keji,S. T; Oluwayinka,P. O; Abayomi,T. A; Ajayi,S. A.
The microarchitecture of the pangolin's stomach favouring the high chitinous diet has been less waived into, despite extensive morphological investigations. Histological analysis of the microanatomy will provide powerful tools for interpretation to yield reliable insights. We investigated this by fixing the tissues in 10% formol saline for histological analysis. Serial sections at 5 µm thickness were subjected to general staining methods for lightmicroscopic study (Haematoxylin and eosin, Van Gieson's and Verhoeff's). The results revealed basic structural arrangements in their coats, with a modification of the epithelial lining of cardia and fundus into stratified squamous keratinized epithelium. These modifications were also reflected in the distribution...
