Abstract
The aim of this work is complex estimation of the nitric oxide action on whole blood of healthy people. We tested the reaction of whole human blood (n=14) to the processing of it with cold NO-containing plasma. We performed direct sparging of blood samples by gaseous flow with NO in a special plant. Cold NO-containing plasma was generated by apparatus "Plazon" (Russia). We tested lactate dehydrogenase activity in direct and reverse reactions, aldehyde dehydrogenase and superoxide dismutase activity, total protein and lactate level, acid-base balance and the partial pressure of gases in blood. For integral assessment of energy metabolism changes a number of derivative parameters (coefficients of energy reaction balance and substrate provision) were used. Our experiments showed, that the processing of whole human blood with NO-containing gas flow (NO concentration--800 ppm) results in significant changes of its physical and chemical parameters. This exposure leads to inhibition of erythrocytes energy metabolism, decreasing plasma antioxidant reserves, developing moderate ionic disorders and acid-base disbalance in blood samples in vitro.
