[Lipid peroxidation and calcium transport in rat liver microsomes after chlorofos poisoning and the effect of atropine and verapamil].
Structural and functional state of rat hepatocytes endoplasmic reticulum membranes intoxicated with chlorofos (0,0-dimethyl-(1-oxy-2,2,21-trichloroethylphosphonate) was studied. It was shown that in case of intoxication a breakage of the membrane Ca(2+)-transport function was accompanied by modification of the membrane phospholipid lipoperoxidation processes and by conformational change of proteins. It is established that prophylactic injection of m-cholinolytic atropine and Ca(2+)-channel antagonist verapamil lead to normalization of processes of ATP-dependent potassium ion transport and lipid peroxidation processes (LPO) in the liver microsomal membranes of intoxicated animals.
