THE CHANGE OF LIPID PEROXIDATION PRODUCTS AND SUBSTRATE COMPONENTS IN THE LIVER TISSUE AGAINST THE COLD EXPOSURE UNDER THE INTRODUCTION OF INDIRECT MUSCARIN-SENSITIVE AND NIKOTINE-SENSITIVE CHOLINOMIMETICS

Abstract

The aim of the research is to study the influence of indirect cholinomimetic substances (proserin, phosphocol) on the content of products and substrate components of the lipid peroxidation at short exposure to cold. 60 rats were the object of the research; cooling of the animals was done daily during 3 hours in the climate camera with the temperature -12ºС. There was revealed the content of methyl ether of monocarbonic fatty acids in liver common lipids, and of molecular oxygen; the ability of liver homogenate to produce active forms of oxygen and products of lipid peroxidation (free-radical) at introduction of indirect muscarin- and nicotine-sensitive cholinomimetics (proserin in the dose of 0.2 mg/kg, phosphocol in the dose of 0.02 mg/kg) was also determined. It was found out that short cold exposure contributed to the increase of diene conjugates; at the same time there was the decrease of hydroperoxides in the common liver lipids, and of malonic dialdehyde in the liver homogenate; there were also changes in the content of the methyl ethers of monocarbonic fatty acids in common liver lipids, the growth of molecular oxygen in the liver tissue. The introduction of proserin and phosphocol against cold exposure (cold oxidative stress) increases the content of malonic dialdehyde in the homogenate of the liver mostly decreasing the level of primary peroxidation products – diene conjugates and hydroperoxides in the common lipids of the liver.
