Technological development, industrialization and economic development have improved living standards, but also increased toxic metal emissions in the living and working environment. The aim of this study is the monitoring of lipid peroxidation in case of acute intoxication by heavy metal cadmium and the protective role of α-lipoic acid. In this study, we used healthy albino Wistar female rats, two or three months old. Based on the results obtained in this study, we note that cadmium-induced intoxication increases the level of malondialdehyde (MDA) in the pancreatic tissue homogenate. MDA is a direct indication of lipid peroxidation. Alpha-lipoic acid suggests reduction and correction of the toxic effect of cadmium after its exposure.
