[Biochemical characterization of viral hepatitis in humans, using and not using narcotics].

Aim: To compare biochemical changes in viral hepatitis (VH) in drug abusers (DA) and non-abusers (NA).

Material And Methods: Hepatic function was examined in 1125 patients with parenteral hepatitis, 540 of them were DA. Transaminases tests and protein precipitation tests were made at the disease height and in convalescence.

[Microcirculation in patients with viral hepatitis B taking ephedrone].

Circulation in ocular conjunctival vessels was studied in patients with viral hepatites B and B + C. Intravascular, vascular (mainly venular), and capillary changes were observed during the acute period of disease. The most common disorders were erythrocyte aggregation, venous congestion, and reduction of capillary network.

[The immune response of viral hepatitis patients who use narcotic preparations].

The characteristics of cell-mediated and humoral immunity were studied in 611 patients with different etiological forms of acute virus hepatitides (HB, HC, HB + C, HC + HBsAg). As the result of the systematic abuse of psychoactive preparations, introduced by intravenous injection, in 166 patients (27.2%) drug addiction developed, ehile 445 (72.

[The prevalence of hepatitis B and C markers among narcotic users].

611 patients with acute parenteral virus hepatitis (VH) were studied with a view to find out markers indicating the presence of hepatitis B and hepatitis C virus infection (HB, HC, HB + C, HC + HBsAg). Of these, 166 patients (27.2%) systematically used narcotic drugs intravenously.

[The dynamics of the basic factors of nonspecific resistance in North Asian tick-borne typhus].

At the acute period of tick-borne typhus an increase in the activities of the main nonspecific resistance factors of the body, and particularly lysozyme, betalysins, complement and properdin, is observed. During convalescence the concentration of lysozyme normalizes and the content of betalysins remains sufficiently high, this indicating that, even in the absence of clinical sings of the disease, the disturbances in homeostasis persist. A decrease in the levels of complement and properdin during convalescence is seemingly linked with their consumption for the formation of immune complexes, eliminated from the body.
