[The effect of PMSG on the trypsin inhibitory activity of the blood and cervical mucus and on the reproductive organs in sheep during anestrus].
The effect of the doses of 750, 1000, and 1500 I. U. PMSG (Antex Leo) on changes in the trypsin-inhibition activities (TIA) of the blood plasma and cervical mucus of ewes was found to vary: a) in the times (from PMSG administration) of recording the minimum values of total TIA (72, 48, 24 hours); b) in the values of the average total TIA on individual days of the trial (40.3-141.4% of the control values); c) in the fractions of low-molecular TIA after administration of 750 and 1500 I. U. PMSG, the fractions exhibited minimum values after 24 hours, and of 1000 I. U. after 72 hours (53.0 and 60.4, and 69.7% of the control values, respectively); d) in the highest values of the fractions of low-molecular TIA recorded after 96 hours (96.1-183.7% of the control values); e) in the average values for 96 hours of the trial, which ranged from 64.1% (1500 I. U.) to 77.1% (750 I. U.) for total TIA and from 89.6% (750 and 1000 I. U.) to 122.8% (1500 I. U.) for low-molecular TIA; f) in the ratio of atretic and non-atretic (A/N) tertiary follicles, which grew with increasing PMSG doses; this was indirectly correlated with the average values for total TIA; g) in the weights of uteri and ovaria which increased from 176.8 to 322.3% of the control values after the stimulation; h) in the epithelium thickness of cervix and cervical glands increasing from 118% to 316% of the control values; i) in the average TIA values of cervical mucus ranging from 53.3 to 125% of the control values.
