Abstract
Full functioning of the leucocytes’ energy supply system is one of the essential factors for the immune surveillance system effective work. The pivotal enzymes of the leucocytes’ energy biotransformation system are NADH-ubiquitin reductase, a marker of the Complex I of respiratory chain activity, and succinate dehydrogenase, key enzyme of the Complex II of respiratory chain. The aim of research – to study the NADH-ubiquitin reductase and succinate dehydrogenase activity of the blood leucocytes’ mitochondria under the conditions of toxic hepatitis induced against the background alimentary deprivation of protein. It is shown, that under the conditions of acetaminophen-induced hepatitis a reduction of the NADH-ubiquitin reductase enzymatic activity is observed on the background activation of the succinate-dependent way of the mitochondrial oxidation. Conclusion was made that alimentary deprivation or protein is a factor, aggravating the misbalance of the energy biotransformation system in the leucocytes of rats with toxic hepatitis. Established activity changes of the leucocytes’ mitochondria respiratory chain key enzymes may be considered as one of the mechanisms, directed on the maintenance of leucocytes energy supply on a level, sufficient for their functioning. Research results may be used for the biochemical rationale of the therapeutic approaches to the elimination and correction of the leucocytes’ energy metabolism disturbances consequences under the conditions of acetaminophen-induced hepatitis, aggravated by the alimentary protein deprivation.
