Tissue concentrations of eosinophilia in the bovine oviduct and uterus of different stages of the oestrous cycle.
Numbers of eosinophils in the bovine oviduct and uterus were determined during the oestrous cycle. The eosinophil numbers in the oviduct (ampulla and isthmus) and horn of the uterus during oestrus were significantly higher than during dioestrus. The number of eosinophils in the uterine cervix was lower than in the uterine horn for all stages of the oestrous cycle. In the oviduct, eosinophils accumulated in the lamina propria of the tunica mucosa, in the tunica muscularis and in the connective tissue of the tunica serosa. In the uterus, they were concentrated mainly in the upper parts of the stroma in the endometrium. Degranulation of eosinophils was observed during oestrus when they increased in number in the oviduct and uterus.
