Experimental amniocentesis and teratogenesis. 2. Control of teratogenicity.

An attempt was made to ameliorate or eliminate the teratogenicity of experimental amniocentesis a) by reducing the calibre of the needle used to puncture the amniotic membranes, and b) by applying a surgical hemostatic sponge over the puncture site. It was found that although neither attempts altered the deleterious effects of amniocentesis on the fetal parameters of weight, crownrump length, and length-weight ratio, the incidence of fetal mortality decreased as the calibre of the needle was reduced. Evidence regarding the ability of the Gelfoam seal to ameliorate the teratogenicity of amniocentesis was conflicting and inconclusive.

The effects of prostaglandin E2 on pregnancy and embryonic development in mice.

The prostaglandins comprise an important and unique group of naturally occurring biological regulators. These substances are currently being widely used for the induction of labor and termination of pregnancy. The effects of prostaglandin E2 (PGE2) on pregnancy and embryonic development were investigated in Swiss-Webster mice. PGE2 induced a high incidence of abnormal offspring in mice when administered subcutaneously on either day 9, 12 or 15 of gestation. In addition, fetal growth was significantly affected following treatment with the prostaglandin on either the 12th or 15th day of gestation.

Placental transfer of tritium-labelled prostaglandin A1 in the rat.

Pregnant Long Evans rats were treated with 25 muCi 3 H-prostaglandin A1 on either gestational day 15, 18 or 21. The highest concentrations of radioactivity were found in maternal kidneys, lungs and liver. The levels of radioactivity in the gut and also in amniotic fluid markedly increased with time after isotope administration. Significant levels of radioactivity were present in fetal tissues and in the placenta.

Experimental studies on the effects of aluminum on pregnancy and fetal development.

The effects of aluminum on pregnancy and fetal development were investigated. Aluminum in the form of aluminum chloride was administered intraperitoneally to pregnant rats at different dose-levels and at different stages of gestation. A high incidence of maternal death followed treatment with high dose-levels of the substance. Maternal weight gain during the entire gestational period was less in treated animals, compared to controls. In many cases, maternal liver was severely damaged as a result of the treatment. The offspring of mothers treated with aluminum chloride showed significant growth retardation as well as skeletal defects. In addition the incidence of fetal deaths and resorption was significantly increased.
