Effect of the different doses of acrylamide on acetylocholinoesterase activity,thiol groups,malondialdehyde concentrations in hypothalamus and selected muscles of mice

Acrylamide is a chemical compound that typically forms in starchy food products during high-temperature cooking,including frying,baking and roasting. acrylamide is a known lethal neurotoxin. its discovery in some cooked starchy foods in 2002 prompted concerns about the carcinogenicity of those foods. little is known about acrylamide’s influence on the peripheral nerves. in our research we measured acrylamide’s influence on the acetylcholinesterase activity in hypothalamus,heart muscle,skeletal muscles of the thigh and smooth muscle of the small intestine (males,swiss strain) in relation to the thiol groups and malondialdehyde concentration. acrylamide was injected intraperitoneally (20 and 40 mg/kg,i.e. 0.52 and 1.04 mg per animal). the hypothalamus and muscles were taken 24,48,and 192 h after the injection. acetylcholinesterase activity was significantly lower (p < 0.001 to p < 0.05) in all structures. it was accompanied by the statistically significant (p < 0.001 to p < 0.05) increase in malondialdehyde concentrations in most of the studied structures time periods and acr doses. –sh groups concentrations were significantly depleted in selected structures (p < 0.001 to p < 0.05). the ache activity evaluation in mice muscles and hypothalamus was very important because there are many evidences that acrylamide affects directly on the peripheral nerves. thus,it causes structural damages and physiological changes. the results obtained in the present study provide evidence for the occurrence of oxidative stress after intraperitoneal injection of acrylamide to hypothalamus,heart muscle,skeletal muscles of the thigh and smooth muscle of the small intestine. © 2017,polish physiological society. all rights reserved.
