Injection of rabbits with a sublethal dose (0.2mglkg) of Naja haje venom induced an increase in serum cortisol, free cholesterol, glucose and potassium ions. A decrease in total cholesterol and sodium ions was observed while the progesterone level was not changed. These results suggest that the cobra venom has induced a stimulatory effect on the glucocorticoid activity paralleled with a depress...

PROBLEM The therapeutic value of progestogens in threatened abortion is still under debate. In the presence of sufficient progesterone levels during pregnancy, lymphocytes synthesize a mediator [progesterone-induced blocking factor (PIBF)] that is anti-abortive in mice. The aim of this study was to evaluate the effect of dydrogesterone on pregnancy outcome of threatened aborters. METHOD OF ST...

Serum progesterone measurement has been advocated as a diagnostic tool in the non-invasive diagnosis of ectopic pregnancy. To assess the accuracy of a single serum progesterone measurement in the diagnosis of ectopic pregnancy, a meta-analysis was performed incorporating 26 studies evaluating the performance of single serum progesterone measurement in the diagnosis of ectopic pregnancy. A disti...
