Intramuscular administration of metachlopromide (2.5, 10, and 25 mg) induced increase in serum prolactin levels. Following 10 and 25 mg dose levels, prolactin levels were elevated at least for 8 hr. Single administration of metachlopromide failed to affect the nocturnal rise in circulating levels of testosterone. Daily treatment of metachlopromide (10 mg)(More)
Uterine strips were collected from cows during the follicular and the luteal phases as well as from cows with ovarian cysts. The strips were mounted in organ baths and the motility was recorded by a polygraph. After the spontaneous motility of the strips had reached a steady state the test substances PGF2 alpha and oxytocin were added to the bath at three(More)
The antiprogestin ZK 98.299 (onapristone) was injected subcutaneously (25 mg/day) for 4 consecutive days during early pregnancy to 8 bonnet monkeys. Retrospective analysis of the data showed that the treatment was initiated between 20 to 30 days after the mid-cycle peak in estradiol levels. In 7 animals, vaginal bleeding was induced within 3.6 +/- 2.7 days(More)
Studies were undertaken in adult bonnet monkeys to investigate whether treatment with an antiprogestin ZK 98.734 at weekly intervals, starting from day one of menstrual cycle, could arrest ovulation and also to determine if ZK 98.734 induced blockade of ovulation could be reversed with gonadotropins. Adult animals have ovulatory menstrual cycles of normal(More)
Blood is most essential constituent in human body. Blood centers collect, process and transport blood to hospitals and other health care centers. Sometimes blood is collected directly from blood donors rather than taking it from blood bank. Nowadays donor safety is major issue as blood is collected from different donors. Small amount of donors face(More)
ZK 98.299 is a potent progesterone antagonist. Its effects on folliculogenesis, bioactive LH, ovulation and menstrual cycle (m.c.) length were studied in adult bonnet monkeys. ZK 98.299 (20 mg/day) was administered s.c., once daily on days 5 to 15 of m.c., to ten animals. The pretreatment m.c. was of 26.5 days (25 to 28 days, mean with 95% confidence(More)
The effects of a progesterone antagonist ZK 98.734 (lilopristone) on implantation, early pregnancy, and midpregnancy were studied in the common marmoset, Callithrix jacchus jacchus. Treatment (5 mg/da intramuscularly for 3 consecutive days) on day (n = 8) after the midcycle peak in estradiol levels in mated animals induced a premature drop in plasma(More)
