[CHARACTERISTICS OF THE RETINA IN CHRONIC STRESS IN LABORATORY RATS OF DIFFERENT AGE GROUPS].

The retina was studied in albino laboratory male rats of two age groups (12 and 24 months), 10 animals in each subjected to chronic combined stress. The stress was caused in animals by simultaneous exposure to pulsed light, loud sound, swinging and restriction of mobility for 7 days, 30 mm daily. The retina of intact rats of the corresponding age groups (n = 20) served as control.

[Synthesis, isomery, and hypotensive activity of thiethane-containing ylidenehydrazides of uracilylacetic acid].

Using reaction of hydrazide 2-[6-methyl-1-(thiethane3-yl)uracil-3-yl]acetic acid with arylaldehydes and acetophenone derivatives were obtained acylhydrazones, which exist in DMSO solution as a mixture of two stereoisomers of a E(C=N)-isomer for due to hindered internal rotation around the hydrazide bond. It was revealed that the synthesized compounds exhibit antihypertensive activity.

[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.

[Studying the neuroprotective effect of the novel glutamic acid derivative neiroglutam on focal cerebral ischemia in rats].

We have studied the neuroprotective effect of the novel glutamic acid derivative neiroglutam on reversible focal cerebral ischemia in rats. The neuroprotective drug action was assessed by the ability to reduce the severity of neurological deficit (1, 2, 3, 5 and 7 days), forelimb fine-motor disorders (in the ladder test), hind limb motor activity (beam-walking test), and volume of the infarct zone upon 7-day pathologic exposure. It was found that the therapeutic administration of neiroglutam (26 mg/kg, i.

[Neuroprotective effect of neuroglutam under conditions of activated free radical oxidation].

The neuroprotective properties of the novel glutamic acid derivative neiroglutam have been studied in vitro and in vivo. Neiroglutam demonstrated the protective action on 6-OH-dopamine neurotoxicity model in vitro, where free radical oxidation is a basic part of pathogenesis. In control rats, focal brain ischemia caused significant increase in thiobarbituric acid reactive species (TBARS) level and decrease in superoxide dismutase (SOD) enzyme activity.
