Methods: Experiments were carried out on outbred albino male rats (n = 150, 230-250 g). For modeling dislipoproteinemia (DLP) we used 3 models: single intraperitoneal injection of the detergent triton WR-1339; administration of ethanol; maintenance on a special hypercholesterolaemic diet (HD) during 21 days. Animals were divided into four groups: normal control, model group, gemfibrozil (Gfb) group, benzohexonium (Benz) group. Rats received per os benzohexonium (20mg/kg), reference drug gemfibrozil (50 mg/kg). We determined content of total cholesterol (TCh), triglycerides (TG) in samples of blood serum and liver, TCh in aorta. TCh, TG and Ch-HDL were analyzed spectrophotometrically using of standardized methods. Results: Compared with model group the contents of TCh, TG in serum and liver were significantly decreased in model + Benz group, whereas Ch-HDL was raised in rats fed special HD (P<0.05). Calculated index of atherogenity (TCh - Ch-HDL) / (Ch-HDL) showed the positive effect. Conclusion: The results obtained were shown the hypolipidemic activity of N-cholinergic antagonist Benzohexonium (20 mg/kg) lowered the content of lipids in blood, liver, and aorta.

The results obtained on the model of starvation shows that nutritional dropsy led to the significant decrease of glucose, total cholesterol (TCh) and triglycerides (TC), as well as increase of non-estherified fatty acids (NEFA) in blood serum. In the rats with nutritional dropsy after treatment fed with standard diet enriched with soybean protein body weight returned to normal values as well as levels of Glucose, TCh and TC. However, concentration of NEFA remained increased. In the experimental group received additionally taurepar or taurhythman the level of NEFA decreased up to the normal one. It is necessary to mention that taurine derivatives did not change the biochemical parameters in blood of normal non-starved rats. We suppose that these new substances promote reduction of intensity of hyperlipidemic processes. It is known, that during starvation incomplete oxidation of fatty acids leads to acidosis with following destruction of mitochondria membraine. Finding property of taurine derivatives to decrease the concentration of non-estherified fatty acids points at their ability for restoration of tricarboxilic acid's cycle and prevention of accumulation of suboxidized molecules of NEFA and acidosis development.

Therapeutic properties of a novel taurin N-phenylakyl derivative (TAU-15) in a dose 25 mg/kg were studied in male rats on models of chronic toxic hepatitis and partial hepatectomy. A hepatoprotective action of TAU-15 was established which is due to antioxidative action of TAU-15 and its ability to normalize protein-synthetizing activity of hepatocytes.

The influence of a new N-phenylalkyl derivative of taurine in combination with a diet enriched with soybean proteins was studied in rats with nutritional dystrophia induced by 3/4 reduced standard diet. It is shown biochemically and morphologically that usage of the drug simultaneously with the diet stimulated protein synthesis, reduced lipid peroxidation, normalized spermatogenesis and compensatory adaptation of different functions.
