Morphological changes in the liver parenchyma in rats under subacute acrylamide intoxication and the possibility of their preventive treatment

Abstract

Introduction. Acrylamide, used in industry, is also formed in foods during high temperature processing. Acrylamide has a toxic effect on the nervous, reproductive, and other systems of the body, due to carcinogenic and genotoxic properties. Considering sufficiently serious threat of acrylamide to human health, it is relevant to carry out further fundamental research to study the mechanism of its impact on the body and the possibility of treatment of lesions caused by it. The aims of this study is to assess morphological changes in the liver of experimental animals under acute acrylamide intoxication and study the possibility of their preventive treatment with complex compounds based on oxymethyluracil. Materials and methods. Experimental studies on the subacute effects of acrylamide at a dose of 20 mg/kg on the histological structure of the liver were carried out on outbred female rats. The efficiency of preventive administration of complex compounds of oxymethyluracil with ascorbic acid, with sodium succinate and acetylcysteine ​​was also studied. Results. Exposure to acrylamide for 28 days at a dose of 20 mg/kg of body weight in experimental rats, has been established to cause minor morphological changes in the structure of the liver: only focal cellular infiltrates were found in the centrilobular zones. In groups of rats that received preventive treatment with complex compounds based on oxymethyluracil, no formation of infiltrates and other pathological changes was observed. Limitations. Limitations of the study are related to implementation of experimental studies of the pathomorphological changes in the liver of experimental animals using only one dose of acrylamide - 20 mg per kg of body weight during one limited period (28 days). Conclusion. Exposure to acrylamide for 28 days at a dose of 20 mg/kg of body weight causes minor morphological changes in the structure of the liver in experimental rats. For the first time, the effectiveness of prophylactic correction of the toxic effect of acrylamide with complex compounds of oxymethyluracil with ascorbic acid, sodium succinate and acetylcysteine, which showed a certain protective effect on the liver, was studied.
