[Specific features of nesting bird populations in forest-meadow-field landscapes of Meshchovsk Opolye reflect the diversity of their biotope connections].

Studies on specific features of nesting bird populations in patchy landscapes were performed in Meshchovsk Opolye, Kaluga Region, from 1981 to 1990. Indices of similarity between the avifaunas of agricultural fields, lowland bogs, and small-leaved forests markedly differed from parameters of their population density in rank and value. In the series of biotopes differing in the relative amount of woodland, from central areas of small-leaved forests to forest margins and then to forest islands gradually decreasing in size, the birds segregated into two distinct groups, one characteristic of forest margins and large forest islands and the other characteristic of small and very small forest islands.

Treatment of syphilis with azithromycin.

The efficacy of oral azithromycin (500 mg daily for 10 days or 500 mg on alternate days for 11 days) in 100 patients with seropositive syphilis was studied. Clinical manifestations regressed more rapidly in azithromycin-treated patients compared with patients who received erythromycin or penicillin, and there was also a more rapid reduction in serum antibody levels. In 90.

[The Extencillin treatment of patients with early forms of syphilis].

Outpatient treatment of syphilis was given to 250 patients. All of them received extencilline (benzathine penicillin G) in intramuscular injections. One injection of the drug (2400000 U) was administered for primary seronegative syphilis (15 cases) and for prevention (65 subjects).
