[The clinico-epidemiological characteristics of HIV infection and AIDS in Ukraine].

The summarized results of the observations of 449 hospitalized patients, aged mainly 18-37 years (40 patients with active AIDS, 43 patients with AIDS, other patients were HIV carriers and infected at the stage of lymphadenopathy). In most of the HIV-infected patients the infection process progressed in 3-5 years, which was manifested by associated candidiasis in 74.7% of cases.

[Characteristics of the morphofunctional status of lung macrophages in the phagocytosis of particles of varying cytotoxic action].

The cytotoxic effect of quartz and coal on phagocytizing lung macrophages was studied by transmissive and scanning electron microscopy and histochemically (the detection of acid phosphatase). The level of phagocytic activity, the activity and localization of acid phosphatase, the number and state of organelles, and the type of macrophage surface processes were shown to represent the objective criteria of the morphofunctional state of macrophages and the cytotoxic effect of the particles phagocytized.
