This is manifested by an increase in the content of endogenous intoxication indicators in blood serum (molecules of medium weight by 84% and 126% (p<0.001) and erythrocyte intoxication index by 86% (p<0.001)). There is a direct correlation of mean strength between the severity of the disease and the level of MSM254 and MSM280 (r=0.496 and r=0.557, p<0.01) and weak strength - with an erythrocyte index of intoxication (r=0.253, p<0.01). COPD in the exacerbation phase is accompanied by the activation of free radical processes, most pronounced in patients with severe broncho-obstruction, manifested by a probable increase in malondialdehyde - by 116% (p<0.001) and a decrease in the activity of superoxide dismutase - by 59% (p<0.01) compared to the control. There is a direct mean strength correlation between severity and malondialdehyde levels (r=0.486, p<0.01) and inverse with serum superoxide dismutase (r=-0.500, p<0.01).
