Study of the effect of lipopolysaccharide (LPS) of Y. pseudotuberculosis on the culture of peritoneal macrophages of guinea pigs has established that in concentrations of 1-10 micrograms/ml LPS stimulated the absorption and digestive activity of the macrophages. In concentrations of 50-100 micrograms/ml it had a cytotoxic effect on the cell elements and inhibited their phagocytic function.

The activity of superoxide dismutase and glutathione peroxidase drastically reduced 2-15 minutes after ligation of the coronary artery and remained at the decreased level during the observation period (14 days). The activity of glutathione-S-transferase in the infarcted zone of the myocardium significantly decreased only by day 3 of the experiment.

Hypercholesterinemia was found in 43% of the cases, lowered cholesterol, high density lipoproteins or hypoalphacholesterolemia in 75%. Thus hypoalphacholesterolemia correlates with CHD more frequently than hypercholesterolemia.
