Garden egg nutritional values are numerous. However, few nutritional and epidemiological data exist on the impacts of garden egg consumption on diabetes control. In this experimentally-control designed nutritional study, the effects of scarlet garden egg species (Solanum aethiopicum L.) on lipoglycemic profile, weight control and, pancreas histoarchitecture in diabetic male Wistar rats were examined. Twenty-One adult male Wistar rats inducted with diabetes were randomly categorized into three groups (n = 7, each): Diabetic control (DC); Diabetic treated with aqueous extract of garden egg (DEE) and Diabetic fed with garden egg-supplemented diet (DSE). Animals were fed for six weeks according to the experimental design. Glycemic status and body weights were assessed twice weekly while lipid analysis was conducted at the entry and 6th week of the study. Oral glucose tolerance (OGT) test was conducted. Gross analysis and tissue histology of the pancreas were assessed by Hematoxylin and Eosin (H&E) staining technique. Statistical analysis was done using analysis of variance, and the results were expressed as mean ± S.E.M. at P < 0.05. Garden egg reduced mean body weight gain (DSE: 14.53%; DEE: 10.58%; P value = 0.04) and decreased blood glucose concentrations (DEE: 37.33%; DSE: 18.68%; P = 0.03) with corresponding improved lipid profile, glycemic tolerance and control (DEE > DSE) and, preserved pancreas histoarchitecture in diabetic Wistar rats. Solanum aethiopicum (garden egg) consumption (as fresh fruit or supplemented diet) preserves pancreatic tissue histoarchitecture and improves lipoglycemic profile and weight control in diabetic Wistar rats.

This study evaluated the effects of aluminum sulphate exposure on the histology of adrenal gland of Wistar rats. Thirty adult Wistar rats were used for this study. The Wister rats were divided into three groups; group A was the control animals and tagged C, group B animals received 10g of alum dissolved in 1000cm3 of distilled water and were tagged T1, group C animals received 50g of alum dissolved in 1000cm3of distilled water and were tagged T2, via drinking water for duration of four weeks. Twenty-four hours after the last administration, the rats were sacrificed by cervical dislocation. The adrenal gland was excised and preserved in 10 % formosaline after which it was routinely processed for hematoxylin and eosin staining (H&E). Histological observations showed normal cell distribution in the control group but treated group revealed evidences of cellular obliteration& hemorrhagic necrosis. The results obtained from this study suggest that aluminum sulphate has a damaging effect on the structure of the adrenal gland.

Coccidiosis in poultry is caused by protozoan parasites of the Eimeria species, which is responsible for worldwide economic losses. The aim of this study was to evaluated the therapeutic effect of NeemAzal® on Eimeria tenellain broiler Chickens as compared to Amprolium as a standard anticoccidial drug. A total of One Hundred and Sixty (160) broiler chicks were purchased, acclimatized and randomly divided into 4 groups (G1, G2, G3 & G4). G1 non-infected, non-treated (negative control), (G2) infected with 20000 E. tenella oocysts (positive control), (G3) infected and treated with Amprolium (Standard, 7 mg/kg b.w. for 5 days) and (G4) infected and treated with NeemAzal®200 mg/kg b.w. for 5 days). Evaluation was by clinical signs, performance data (weight gain, oocyst shed/gram faeces (OPG) and histopathology of the Caecum, Liver and Kidney. The data showed that birds infected with E. tenellahad an output of 1.3×105±3,333 oocysts per gram faeces on day 5 post inoculation. This output is significantly decreased to 0.37×105±3,111 oocysts in neem-treated birds. Infection with E. tenellainduced marked histopathological alterations in the caecum in the form of inflammation, vacuolation of the epithelium, and destruction of some villi. NeemAzal® decrease body weight loss of infected chickens. Moreover, the number of goblet cells stained with Hematoxylin and Eosin (H&E) within the infected villi was significantly lowered (P≤0.05). The results revealed that chicks of G1 had the best performance data compared to G2, G3& G4. In G3 & G4 there were a remarkable improvement in the data on performance, clinical signs, gross and microscopically caecal lesions compared to G2. Amprolium (G3) was shown to be superior to NeemAzal® (G4) compared to G2. NeemAzal® could be a good alternative for use as a coccidiostat to supplement the expensive anti-coccidiostats in the market.

Relationship Between the Immunodetection of Alpha-Smooth Muscle Actin and the Aggressiveness of Mammary Papillar Tumors in Female Dog

Papillary carcinoma is a mammary neoplasia of women and female dogs characterized by papillary fibrovascular projections lined by epithelial cells. Evaluation on the biology of these tumors can be done by immunohistochemistry through detection of alpha-smooth muscle actin protein in the papillary myoepithelium, which lacks such a molecule during malignant proliferations. Thus, this study aimed at determining the malignancy degree of papillary mammary tumors of female dogs by immunohistochemistry. Twenty samples of mammary neoplastic tissues collected from female dogs treated in the Veterinary Hospital at FCAV were evaluated by Hematoxylin and Eosin staining (H&E) and tumor cells were immunolabelled with monoclonal antibody to alpha-smooth muscle actin (α-SMA). Five out of 20 cases showed positive immunolabeling greater than 10% of the total immunolabeling. The remaining fourteen cases presented immunostaining lesser than 10% showing decrease or absence of α-SMA labeling in the myoepithelium of the papilla tumors. All those cases in which immunostained cell was over 10% of the neoplasm (5 immunostains of 20 total cases) were classified as benign whereas those below 10% of immunostained in the slid were considered as malignant. Therefore, immunohistochemistry played an essential role in differentiating benign and malignant papillary tumors of bitches as already described for female. Tumor classification by conventional methods, such as H&E staining, can lead to erroneous interpretations on the real biological behavior of the papillary mammary tumor.

Introduction: Granulomas in gastric biopsy specimens are extremely rare. The final diagnosis of granulomatous gastritis is based on morphological findings, clinical and laboratory data. The aim of our study is to evaluate the clinical fields and to determine the etiology of gastric granulomatosis in our experience Patients and Methods: Thirty nine patients were reviewed retrospectively in the department of pathology of Habib Thameur between 2000 and 2018. Slides from all cases were stained by hematoxylin and eosin. The clinic-pathologic findings and the associated lesions were analyzed and the final etiology of the gastric granulomatosis was noted. Results: Biopsies from the 39 patients diagnosed as having granulomatous gastritis were reviewed. Mean age was 49 years (24 – 96) and sex ratio was 0,25 (M/F=8/31). Indication of endoscopy was gastric pain in 12 cases, chronic diarrhea in 6 cases, anemia in 2 cases, vomiting in 4 cases. Other symptoms were rare. Upper endoscopy was normal in 8 cases, showed antral gastropathy in 20 cases (erythematous in 6 cases, nodular in 8 cases and ulcerated in 6 cases). In four cases, fundic lesions were observed. Granuloma was unique in 14 cases and multiple in 25 cases. Localisation of granuloma was the antrum in 25 cases, the fundus in 7 cases, and both of them in 7 cases. An associated chronic gastritis was noted in 25 cases. Concerning the etiology, 10 of our patients had Crohn's disease while 6 of them had gastric tuberculosis. In five cases, H Pylori was the retained cause of gastric granulomatosis. In the other patients, the final diagnosis was sarcoidosis (n=3), foreign body reaction (n=1), yersiniosis (n=1). In our series, thirteen cases were unclassifiable. Conclusion: Although many cases remain unclassified, in most cases of granulomatous gastritis, a diagnosis of Crohn's disease or tuberculosis could be established. If this cases are excluded, an association between H. pylori and granulomatous gastritis cannot be ruled out. The others causes are extremely rare.
