Immunopresence of the progesterone receptors (PR) and proliferative activity in the bitch uterus were studied during different stages of the oestrous cycle. Uterine samples were collected at 4 different stages of the oestrous cycle; prooestrus, oestrus, dioestrus and anoestrus. Immunohistochemistry was used to evaluate the localization and to semiquantitate PR and uterine proliferation by using monoclonal antibodies to the PR and the proliferative marker, Ki-67 respectively. The results showed that PR and Ki-67 levels were highest during prooestrus and oestrus while they were low at other stages. However, a significant difference was observed only in the surface epithelium for Ki-67 …
