<abstract xmlns="http://www.w3.org/1999/xhtml">The aim of this paper is to investigate the influence of Thiocetam on morphological changes in the liver of rats and on biochemical changes in their blood after exposure to lead nanoparticles and compounds. The liver is an organ that performs a number of functions, such as the synthesis of enzymes, hormones, plasma components and the neutralization of toxins. It is involved in many metabolic processes in the body.In undertaking this, colloidal solutions of lead sulphide nanoparticles at dosages 10 nm and 30 nm were injected into two groups of rats, PbSnano1 and PbSnano2, respectively, while group Pb(NO3) received subcutaneously a solution of lead nitrate in ion form in a dose of 1.5 mg/kg (0.94 mg/kg lead, in lead equivalent). After 60 administrations (12 weeks) of the studied substances, the exposure was discontinued and the animals were observed for 18 weeks. Subsequently, half of each group received Thiocetam by injection (for 6 weeks at a dose of 250 mg/kg) while the other half did not. We then assessed the mean body weight, absolute and relative liver weight, blood biochemistry values (total protein, albumin, glucose, total lipids, cholesterol, triglycerides levels in blood serum) and morphological changes in hepatocytes (morphological slides, nuclei cross-sectional area and cytoplasm cross-sectional area).The outcome of this work showed that the mean body weight of animals exposed to nanoparticles with Tiocetam did not differ from that of animals exposed to nanoparticles without pharmacological correction, but relative liver weight was statistically significantly higher than the corresponding values in rats without pharmacological correction. The morphological picture in all study group animals was characterized by the normalization of microvessel blood filling, structure of hepatic plates, disappearance of infiltration with lymphocytes and histiocytes. No dystrophic changes in hepatocytes were found. All this indicates the feasibility of preventive measures during exposure to lead nanoparticles, by administering Thiocetam.In both series of animals exposed to lead nanoparticles (PbSnano1 and PbSnano2), the cross-sectional area of the hepatocytes cytoplasm and the cross-sectional area of the hepatocytes nuclei were smaller than just after exposure, but in the series with Thiocetam adminstration, all the values did not differ from those in the control.</abstract>
