RMI 12,936 and pseudopregnancy in rats

Contraception, 1979
RMI 12,936, when injected subcutaneously at a dose of 2 mg, either on Day 6 of psuedopregnancy (PSP-6) or on PSP-6,7 and 8, shortened the duration of PSP from 12.3 +/- 0.3 (control) to 8.3 +/- 0.1 or 8.7 +/- 0.2 days, respectively. During PSP, plasma progesterone (delta 4P) levels in the peripheral plasma showed a trend of decrease by PSP-9 (52.0 +/- 4.

Bronchogenic Carcinoma Presenting as a Pseudopregnancy

Chest, 1995
A young woman with an occult bronchogenic carcinoma presented with secondary amenorrhea and an elevated beta subunit of human chorionic gonadotropin that was mistakenly attributed to pregnancy. Physicians should be aware that this carcinoma may present solely with an elevated beta human chorionic gonadotropin value, and the potential exists for ...

Prolactin and Delayed Pseudopregnancy in the Rat

Endocrinology, 1976
In (RXU)F1 hybrid rats delayed pseudopregnancy was induced in three different ways: 1) by removal of all recent corporl lutea on day 2 of pseudopregnancy, 2) by removal of the in situ ovaries from ovarian graft-bearing animals on day 0 of pseudopregnancy, 3) by administration of 1 mg of ergocornine hydrogenmaleinate (ECO) on day 1 of pseudopregnancy ...

HORMONAL INDUCTION OF PSEUDOPREGNANCY IN RATS

Reproduction, 1965
Summary. Various hormonal methods are compared of obtaining pseudopregnant rats capable of implanting fertilized ova transferred to them. Injection of 20 μg of oestrone to rats on Day 1 of pregnancy, followed by injection of 1 mg/day of medroxyprogesterone on Days 2 to 4, resulted in a high rate of implantation of fertilized ova ...

Ultrastructure of decidualization in the pseudopregnant rat

American Journal of Anatomy, 1983
AbstractThe ultrastructure of the endometrial stroma in rats bearing deciduomata was examined in detail on day 9 (day of vaginal cornification = day 0) of pseudopregnancy, together with the development of deciduomata from day 4 to day 8. Five major regions were recognizable on day 9.

Glomerular ultrafiltration in the pseudopregnant rat

American Journal of Physiology-Renal Physiology, 1982
Whole kidney and single nephron indices of glomerular ultrafiltration were measured by clearance and micropuncture techniques in anesthetized virgin, 9-day pregnant, and 9-day pseudopregnant Munich-Wistar rats. Whole kidney glomerular filtration rate (GFR) and single nephron glomerular filtration rate (SNGFR) were elevated in pregnant and ...

NORMAL AND DELAYED PSEUDOPREGNANCY IN THE RAT

Acta Endocrinologica, 1965
ABSTRACT In rats bearing a transplanted immature ovary under the kidney capsule, the in situ ovaries were removed at oestrus. In spite of this operation the sequence of vaginal oestrous cycles was uninterrupted. Removal of the in situ ovaries on the morning after copulation was followed by one normal vaginal oestrous cycle.

INDUCTION OF PSEUDOPREGNANCY IN RATS WITH MEDROXYPROGESTERONE

Journal of Endocrinology, 1971
SUMMARY A daily dose of 1 mg medroxyprogesterone acetate (MAP) injected into rats for 2, 4 or 8 consecutive days, beginning on the day of oestrus, resulted in a high implantation rate of transferred 5-day blastocysts and a high survival of foetuses to term. The best results were obtained with daily injections of 1 or 2·5 mg of MAP for 3
