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. 相似文献

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. 相似文献

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.

Functioning of membrane oxygenator "MOCT-122" in pulsed operation of bypass in treadmil tests and during clinical perfusions was investigated. It was established that the inclusion of the oxygenator into the test line lead to a considerable decrease in parasitic pulsations both of rate and pressure. The pulsatory character of the flow was observed though the transconductance of increase and decrease fronts of the rate (as the result of oxygenator "MOCT-122" installation) demonstrated their satisfactory functioning. 相似文献
