Our previous studies have demonstrated that naturally occurring peptide, Nisin possess antibacterial activity and did not interfere with rabbit vaginal mucosa. In this study, the reproductive toxicity of the Nisin in male rats was evaluated. Rats were fed orally with Nisin (10, 25, and 50 mg/kg/day) for 13 weeks. No treatment related mortality was observed. The body weight gain, food consumptio...

Adenomatoid odontogenic tumor (AOT) is a relatively rare, benign, hamartomatous, and cystic odontogenic neoplasm that was first described more than a century ago. The lesion still continues to intrigue experts with its varied histomorphology and controversies regarding its development. The present article describes a case of cystic AOT with an unusual histomorphology associated with an impacted...

the purpose of this study was to gain more information on the structure of different layers of renal arteryand comparing these structures in post-natal male and female sheep. to do so, right and left renal arteries of6 adult and 6 newborn animals were dissected; the middle parts of arteries were only collected. after tissueprocessing using paraffin embedding method, 5–6-μm sections were cut and...

morphological and histochemical study of the abomasal epithelium in camel (camelus dromedarius) wascarried out by light and scanning electron microscopes. the lining of the abomasum was divided into fourregions, i.e. cardiac, pseudocardiac, fundic and pyloric. our investigation revealed that the cardiac andpseudocardiac regions occupy a wide part of the abomasum in camel and it reaches approxim...

Small ruminants pancreas is a major accessory organ and has an important role in digestion. Endocrine part of pancreas is Islets of Langerhans which are highly vascularized, consisting of several endocrine cell types that function together to maintain glucose homeostasis. There has been limited scientific work done on the histomorphological study of pancreas in Deccani sheep Bidri goat. The pre...
