[Gravidaprotective action of phenibut in experimental pre-eclampsia].

It was established that the replacement of drinking water by 1.8% NaCl solution in female rats during pregnancy causes experimental pre-eclampsia (EP), as evidenced by an increase in the blood pressure, proteinuria, and edema in the control group as compared to pregnant female rats with normal drinking regime. Animals with EP exhibited disturbance of vasodilating endothelial function, microcirculation disorder, and increased coagulation and thrombogenic potential of blood.

Effect of GABA derivatives on the rate of thrombus formation, platelet aggregation, and plasma coagulation capacity in rats with experimental gestosis.

Experimental gestosis induced by replacement of drinking water with 1.8% NaCl promoted hypercoagulation, increased the rate and degree of platelet aggregation, and reduced clotting time in pregnant females. GABA derivatives, compounds RGPU-151, RGPU-152, and phenibut normalized parameters of hemostasis and platelet aggregation and the rate of thrombus formation in the animals.

[Effect of GABA derivative--RSMU-151 on the development of oxidative stress in rats with experimental gestosis].

Experimental gestosis induced in rats by drinking 1.8% sodium chloride solution instead of water during the entire period of pregnancy leads to activation of lipid peroxidation (LPO) process, as manifested by increased concentration of diene conjugates and malonic dialdehyde, decreased concentration of antioxidant enzymes (superoxide dismutase and glutathione peroxidase) in homogenates of rat brain, liver, uterus, and placenta. The GABA derivatives--RSMU-151 limits the damaging effect of gestosis, which is manifested by a decrease in the concentration of LPO products and by activation of the antioxidant system enzymes in all organs studied.

[Effect of new phenibut salts on psychic and physical development of posterity in rats with experimental gestosis].

Phenibut salts with citric and salicylic acids--compounds RSPU-147 and RSPU-189, respectively--positively influence the psychic (increase in the locomotor and position-finding activity in the open field test and retention of memorable track in the CROA test) and physical (in the revolution, negative geo-taxis, avoidance, and muscular force tests) development of posterity, born from females with gestosis caused by the replacement of drinking water by 1.8% NaCl solution during the period of gestation.
