EFFECT OF FATTY OIL EXTRACT FROM SEEDS OF NIGELLA DAMASCENA L. ON LIPID SPECTRUM IN RATS WITH SIMULATED DYSLIPIDEMIA

The aim of the study is to determine a lipid spectrum of blood plasma and liver in rats in with simulated dyslipidemia against the background of the administration of the fatty oil extract from the seeds of Nigella damascena L. Materials and methods. Laboratory animals – Wistar male rats – were used in the work. To study the hypolipidemic activity, such models as acute Tween, subchronic vitamin-D2 models and a model of chronic heart failure were used. The identifiable parameters were the concentration of cholesterol and triglycerides in the blood serum and liver, as well as the concentration of atherogenic and non-atherogenic lipoproteins in the blood serum, and the atherogenic coefficient. Results. As a result of the study, it was found out that a course administration of the fatty oil extract from the seeds of Nigella damascena L. against the background of simulated chronic heart failure (CHF) by the right ventricular type, normalizes the lipid spectrum of the experimental animals’ blood serum, causing an increase in the concentration of high-density (non-atherogenic) lipoproteins, and reduces the concentration of low-density (atherogenic) lipoproteins. A single administration of the fatty oil extract from the seeds of Nigella damascena L. promotes the correction of lipid metabolism disorders under the conditions of acute Tween lipidopathy, while the direction of the object being studied reduces the concentration of cholesterol and triglycerides in the liver and blood serum under the conditions of subchronic dyslipidemia. At the same time, the effect of the use of the fatty oil extract from the seeds of Nigella damascena L. was not inferior to “Omaсor”, the reference drug. Conclusion. The possibility of using a fatty oil extract from the seeds of Nigella damascena L. for preventive and therapeutic aims in cardiovascular diseases has been established.
