background: due to scarcity of human reports, we took advantage of the heaviest infection of m. moniliformis in rats, to describe histopathological and microanatomical valuable useful keys while confronting human occurrences. methods:   samples were obtained from captured rats in tehran, capital of ira, during two dec­ades.  tissue sections were performed through hematoxylin and eosin staining ...

laboratory animals, including rats, play an important role in biomedical research and advances. the human care and management of these animals is an ongoing concern. since, trichosomoides infections in rat colonies can interfere with research protocols it is important to know rate of infection and pathology of the infection in the animals used in experimental studies. 275 rats were eviscerated ...

conclusions the findings suggest that estrogen supplementation increases damage in testicular tissue due to eccentric exercise. results conventional light microscopic results revealed that testes tissues of the eccentric exercise administered group and the estrogen supplemented group exhibited slight impairment. in groups that were both eccentrically exercised and estrogen supplemented, more de...
