Clinico-epidemiological analysis of the cases of HIV infection in the north-western region of Russia]

The paper provides an epidemiological characterization of HIV infection spread in a Russia's large region with more than 10 million people. The epidemiological findings show that the significant onset of HIV infection occurred among the population in this region in mid 1988. Homosexuals and bisexuals are prevalent among the HIV-infected, sexual contact is the main mode of HIV transmission. In addition to delivery of HIV infection from foreign countries, there are cases of local transmission. The clinical evidence indicates that most HIV-infected people are asymptomatic. Herpes viruses, Mycobacteria tuberculosis, Toxoplasma and fungi are common among causative agents of AIDS-related infections.     

Tissue reactions in children treated with hemodynamic dextran and detoxication polyvinylpyrrolidone plasma substitutes]

By means of light and electron microscopy tissue reactions produced by repeated use of polyvinylpyrrolidone (PVP) and dextran plasma substitutes are studied on the material of 20 autopsies and 4 biopsies as well as in 65 experimental cases. Delayed type of PVP accumulation in tissues after the hemodes administration is determined as well as its dependence on the dose, time, kidney function and the presence of inflammatory foci. The differences in tissue reactions after administration of dextran and PVP substitutes are established. The results indicate that medicinal thesaurismosis may develop only after repeated infusions of PVP substitutes, while dextran accumulation is of a transitory type and results in characteristic morphological changes in the renal epithelium only.     

Effect of oxygen aeroions on platelet aggregation and lipid peroxidation in health and peritonitis

In patients with peritonitis, the biological effects of oxygen aeroions reflect the interplay between molecular and cellular effects manifesting themselves in the inhibition of lipid peroxidation, increased antioxidizing potential of blood plasma, and decreased aggregating activity of platelets.
