Abstract
Three mares suffering from chronic endometritis during the last 34 years were treated with uterine curettage. The clinical, histological and endoscopical observations of the endometrium were carried out before and after uterine curettage in these animals.
The results obtained were as follows:
1. Small follicles developed within 10 days and ovulation occured within 20 days after the treatment. These findings were checked by rectal palpation.
2. Acute inflammatory changes occured in the endometrium on the 4th day after uterine curretage, and then disappeared on the 10th day after the treatment.
3. Histochemically, alkaline phosphatase activities and PAS-positive granules in the uterine and glandular epithefium were evident remarkably on the 4th and 10th day after uterine curettage, respectively.
