Histochemical Study on the Uterine Development in Fetues and Neonates of Korean Native Goats

한국재래산양의 태아 및 신생아 자궁의 조직 발달에 관한 조직화학적 연구

The present study was performed to investigate the patterns of a, pp.arance of lectin in uterus of fetuses of 90 and 120 days old and neonates of Korean native goat. The carbohydrate markers were used in histochemistry for the determination of the lectin by staining of avidin-biotin-per-oxidase complex(ABC), rincinus communis agglutinin(RCA-I), ulexeuropalus communis agglutinin(UEA) and wheat germ agglutinin(WGA). 1. The effects of this study were as follows; 1. The binding reactions for Con-A were weak on the mucosal epithelium of endometrium in 90 and 120 days old fetuses, and neonates and moderate at the free surface of mucosal epithelia. 2. The binding reactions for DBA was partially moderate on the mucosal epithelium of endometrium and partially strong at the free surface of mucosal epithelia in 120 days old fetuses. In neonates, the reactions were strong on the mucosal epithelium and gland primordium of endometrium, and the secretions at the free surface showed strong reactions for DBA. But, in 90 days old fetuses, the reaction was negative. 3. The binding reactions for RCA-I were moderate on the mucosal epithelium of endometrium and at the free surface of mucosal epithelia in 90 days old fetuses. In 120 days old fetuses, the reactions were weak on the mucosal epithelium of endometrium and moderate at the free surface of mucosal epithelia. In neonates, the reactions were moderate on the mucosal epithelium of endometrium and strong at the free surface of mucosal epithelia and also strong in the uterine gland. 4. The binding reactions for UEA were negative in 90 and 120 days old fetuses and neonates. 5. In 90 days old fetuses, the binding reactions for WGA were generally weak on the mucosal epithelium of endometrium, but several epithelial cells showed moderate reaction for WGA. In 120 days old fetuses and neonates, the reactions were moderate on the mucosal epithelium and blood vessels of endometrium and strong at the free surface of mucosal epithelia.
