Background. Lipid metabolism disorders in the organism affected by environmental pollutants, including poisoning with cadmium and lead salts are of topical matter nowadays.

Objective. The study was aimed to examine biochemical features of lipid metabolism in rats subjected to toxic damage by lead and cadmium salts and treated with carnitine chloride and Algigel.

Methods. Experiments were carried out on white mature outbred male rats weighing 180-200 g. To cause the toxic damage the animals were administered with aqueous solution of cadmium chloride and lead acetate daily for the period of 30 days using intra-gastric lavage. The indices of lipid metabolism were detected by biochemical methods.

Results. In animals treated with cadmium chloride and lead acetate the following changes were observed: HDL-cholesterol concentrations significantly decreased, resulting in 87% of the levels in the intact animals on the third day, 84% on the fifth and 80% on the seventh day. Conversely, concentrations of HDL-cholesterol and VLDL-cholesterol significantly increased during the experiment. Respectively, the ratios for HDL-cholesterol are 240%, 352%, and 388%; and for VLDL-cholesterol 108%, 116%, and 132%.

Conclusions. Lipids profile of the rats displayed changes in the levels of cholesterol, triglycerides and lipoproteins of low, high and very low density.



blood lipid profile; heavy metal toxicity.
