[Influence of isoniazid complex with A-I apolipoprotein on activity of lysosomal enzymes in mice with tuberculous inflammation model].

It is established that isoniazid (isonicotinic acid hydrazide) can interact with A-I apolipoprotein to form a complex, which can be considered as the transport form of the preparation. The use of this complex for the treatment of mice with BCG-induced tuberculous inflammation led to an increase in the free activities of acid phosphatase and cathepsin D in the liver, which was decreased under the action of mycobacteria and the free form of isoniazid. The isoniazid complex with A-I apolipoprotein exhibited more expressed anti-inflammatory effect (estimated by the activity of chitotriosidase in blood serum) as compared to the free drug.
