Changes in the distribution of the epithelial and inflammatory cells in the external opening of the uterine cervix in river buffaloes at three different occasions during the gestation period were investigated by light microscopic evaluation of mucus smears prepared by wet swab sampling and Giemsa-stained. Forty five pregnant river buffaloes that were in the first (n=15), second (n=15) and third (n=15) approximately equal parts of their gestation period were sampled twice concurrently by individual wet swabs from the external opening of the uterine cervix. Five smears were prepared from each sample. Immediately after mucus sampling, blood samples were obtained from the jugular vein of each animal, centrifuged immediately and stored at -20 oC to assay the plasma levels of estradiol-17β and progesterone. The results showed that changes in the percentage of the vacuolated and non-vacuolated epithelial cells, lymphocytes, eosinophils, and basophils were not statistically significant between the groups, which suggests that as the pregnancy progressed, changes in the blood levels of estradiol-17β and progesterone had little or no effect on the distribution of these cells in the region, but changes in the percentage of neutrophils were statistically significant between the groups. It was also found that changes in the percentage of macrophages between the second and third trimesters of the gestation period were not significant, but the difference between the first and the other trimesters was statistically significant. It was concluded that the percentages of neutrophils and macrophages increase significantly as the plasma concentrations of progesterone decrease during the gestation.

The relationship between a selective increase in circulating immunoreactive (ir)-inhibin and the time of ovulation was investigated in mares. Concentrations of plasma ir-inhibin were measured every 4 h during the periovulatory period. Inhibin pro-αC, a precursor protein of the inhibin α-subunit, was also measured. The changes in ir-inhibin and inhibin pro-αC in circulation were parallel. Concentrations of both ir-inhibin and inhibin pro-αC in the plasma increased at the same time when ovulatory follicles ruptured, and the peak levels of circulating ir-inhibin and inhibin pro-αC were maintained for 4–8 h. There was no selective increase in plasma concentrations of estradiol-17β during the process of ovulation. These results suggest that the selective increase in ir-inhibin and inhibin pro-αC was caused by the absorption of follicular fluid after the rupture of ovulatory follicles. These results also suggest that the measuring of plasma concentrations of ir-inhibin or inhibin pro-αC in mares might be a useful method for detecting the time of ovulation.

The plasma concentrations of luteinizing hormone (LH) and estrogens (E) were determined for 12 sows, from a herd with a history of postweaning anestrus, from the day of weaning to 32 days after weaning (trial I). A linear increase in plasma LH and E was observed in six sows which remained in anestrus (LH, 0.32–0.47 ng/ml; E, 16.1–24.7 pg/ml). These concentrations were similar to those observed in cycling sows during diestrus. In the remaining sows concurrent peaks of LH and E were observed during proestrus and estrus. In a second trial, two groups each of five sows were treated with a single injection of pregnant mare’s serum gonadotropin (PMSG, 1500 IU) or steroids (estradiol-17β, 1 mg plus progesterone, 2 mg) on the day after weaning. The plasma concentrations of LH and E for 10–12 days after weaning were compared with those of five untreated control sows. In the PMSG-treated group, concurrent peaks of LH (4.7 ± 0.5 ng/ml) and E (121 ± 41 pg/ml) were observed at estrus. The control group produced a lower LH peak at estrus (1.5 ± 0.4 ng/ml) which was not accompanied by a rise in plasma E. No consistent secretory pattern for plasma LH and E was observed in the steroid treatment group.
