Abstract :
Inroduction & Objective: The importance of histophysiological and histochemical study of the uterus, cervix and vagina in mammals is due to pathological examinations of these organs in infectious and metabolic diseases and infertility treatment. The aim of this study was to investigate the histophysiological and histochemical features of these organs in guineapigs.Materials and Methods: Five female guinea pigs with mean weight were obtained from laboratory animal breeding center and after sampling, Samples were stained by Hematoxin - Eosin, Periodic acid Schiff and alcian blue methods and then histological and histochemical properties of samples were samples were studied by light microscope.Results: The horn and the body of the uterus in general have three layers of endometrium , myometrium and primetrium. The endometrical epithelium in the uterine horn consists of simple cubic cells and it consists of simple cubic cells and simple columnar cells in the body of uterus. The endometrium has many coiled tubular glands. In the body and horn, the myometrium has 2 layers of longi tudinal and circular smooth muscle from outside to inside. The cervical mucosa has simple columnar cells. And has 3 types of folds: primary, Secondary and tertiary folds. Among the columnal cells, a large number of mucus secreting goblet cells are seen. The squomous vaginal epithelium is stratified stratum Corneum. no glands were observed in mucosal layer of the vagina.Conclusion: The results show that the anatomical a tissue structure of Guinea pig uterus, cervix and vagina, despite minor differences, are very similar to other mammals.s.
