Abstract: In order to determine the change characteristics of vaginal cells in the estrus cycle and the duration of the estrus cycle, vaginal smears and HE staining methods were used to observe and count the types, morphological changes, and proportions of vaginal cells in plateau zokor (Eospalax baileyi). The hormone secretion dynamics of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) in the serum of plateau zokor in the estrus cycle were determined by ELISA. The results showed that the main vaginal cells of plateau zokor were leukocytes, nuclear epithelial cells, incompletely cornified epithelial cells, and complete cornified epithelial cells. The proportion of nuclear epithelial cells in the proestrus was significantly higher than that during the other three periods (48. 4 ±3. 09)% (n=12, P < 0. 05). The proportion of complete cornified epithelial cells in the oestrus was the highest and significantly higher than that in the other three periods (59. 73 ±7. 59)% (n=15, P < 0. 05). The proportion of leukocytes in the metestrus and dioestrum was significantly higher than that in the proestrus and oestrus (P < 0. 05). The expression level of LH was the highest in the metestrus (4. 709 5 ±1. 094 0) ng/mL (n=6, P < 0. 05), which showed an increasing trend in proestrus and oestrus, and a decreasing trend in the metestrus and dioestrum. There was no significant difference in the expression level of FSH among the four periods (P > 0. 05); the estrus cycle duration of plateau zokor was 16 to 19 d, the characteristics of vaginal cell types in different stages of the estrus cycle were obvious, and the relative number was statistically significant. The study provided a basis for vaginal smear identification in the estrous cycle and reproductive physiology study of plateau zokor.
