[Determination of quantitative parameters of Escherichia coli phagocytosis by mouse peritoneal macrophages].

The fluorometric method was used to study guantitative parameters of phagocytosis of fluorescein-labeled Escherichia coli cells by mouse peritoneal macrophages. E. coli cells were conjugated with fluoresceinisothiocyanate (FITC) and then incubated with macrophages.

[Infection syndrome in acute radiation sickness patients subjected to Chernobyl accident].

In spite of intensive antimicrobial prophylaxis and therapy, most patients with acute radiation sickness I-IV severity grade (dose of 0.1-13.7 Gy) developed infections caused by bacteria, fungi and viruses.

[Influence of the indometafen radioprotector on the immune reactivity].

In the experiments on dogs and mice it was shown that indometophene could modify the immune status of the body. Specific and non-specific resistance of mice to E. coli infection increased after indometophene administration.

[Strategic problems in counteracting the spread of HIV infection in the Altai Territory].

The Altai Territory belongs at present to regions with the insignificant level of the spread of HIV infection. By December 1, 1999, the Altai Territory had 31 registered cases of HIV infection, which constituted 1.33 per 10,000 of the population (the corresponding figure for the whole of Russia being 14.

[Radiation damage to the hemopoietic system of mice, carriers of the leukemia virus].

The experiments with AKR mice, that are carriers of the T-cell leukemia virus showed their higher radiosensitivity as compared to (CBA x C57Bl)F1 mice in respect of survival and hemopoietic status. The regular patterns observed are presumed to result from lower ability of AKR mice to repair radiation damage and provide resistance to infections.
