Variations in the capacity of the steroid binding beta globulin (SBbetaG) in plasma from normal young twins.

The capacity of human plasma to bind specifically dihydrotestosterone (DHTBC) has been determined in normal monozygotic and dizygotic twins less than 20 years old. The total variation in DHTBC was analysed by stepwise multiple regression, combined with variance analysis, applied to the pair sums in DHTBC, body height and body weight, as well as to age. A significant part of the variation in DHTBC was explained. Due to the strong interwining between body weight, body height and age in growing children it was impossible to make out which one of the latter variable contributed most to the negative correlation which was observed. Previous studies in adults did, however, show that only body weight and not body height or age correlated negatively with DHTBC. By doing the same calculations for the within-pair differences in DHTBC, body height and body weight it was hoped to delineate the within-family part of the environmental variation in DHTBC. Body weight and body height did, however, not offer any significant explanation as to this part of the variation in DHTBC. The upper limit of heritability (h2) for DHTBC was estimated by comparing intraclass-correlation coefficients in monozygotic and dizygotic twins. According to the method used to calculate the latter intraclass-correlation coefficients h2 estimates for DHTBC of 0.774 and 0.960 were arrived at. However, due to the rather small number of dizygotic twins available the confidence limits of these estimates were rather large.

Prostaglandin F2 alpha for interrupting pregnancy, managing intrauterine death and molar pregnancy and inducing labor.

Serial intramuscular injections of 250 microgram of 15 (S), 15-methyl-prostaglandin F2 alpha were given to 105 women every 1-3 hours in an attempt to induce second-trimester abortion (N = 80) or labor (N = 25), the latter because of late intrauterine death or anencephaly. The treatment was highly successful; the cumulative expulsion rates at 12 and 24 hours were 69% and 95%, respectively. There were no serious complications, and significant alterations in the mother's vital signs were uncommon. Gastrointestinal side effects are tolerable if the woman is properly premedicated and maintained on the antiemetic, antidiarrheic and analgesic treatments.

Copper IUDs.

Clinical and fundamental IUD research has made tremendous progress during the last few decades, but many clinical problems still remain unsolved. After a general review of literature data, Author reports his experience with copper-bearing IUDs and their modified models; these modifications have four main objectives: increase of effectiveness, prolongation of the intrauterine life span, improvement of fit, and implementation of effective insertion at immediate postpartum.

Intravenous infusion of prostaglandin E2 for management of premature rupture of membranes.

In term with premature rupture of the membranes (PROM) and an unripe cervix who have no contraindications for prostaglandin (PG) administration and vaginal delivery, intravenous (I.V.) infusion of titrated PGE2 is highly effective. In healthy gravidas with dito fetus this treatment appeared perinatally safe and was well tolerated by the mother. To enhance its safety margin and procedure must be conducted under toco-cardiographic control.
