[The vaccinal prophylaxis of hepatitis B among children born to mothers with persistent HBs-antigenemia].

In Uzbekistan and Moldova 542 children born of HBsAg carriers were immunized against hepatitis B (with vaccine Engerix B according to the immunization schedule of 4 injections). Anti-HBs antibodies in protective titers were detected by EIA and RIA techniques in 76.7% of children aged 4-5 months after the 3rd injection, in 95.

[Risk of infection with hepatitis B and C viruses of medical workers, patients in the hemodialysis ward, and vaccine prophylaxis of hepatitis B infection in these populations].

Markers of hepatitis B (HBsAg, anti-HBs) and C (anti-HCV) were detected in 1990-1992 by enzyme immunoassay in 1581 medical workers, 230 last-year students of medical schools, 269 patients hospitalized at hemoperfusion wards, and 701 blood donors. Hepatitis B markers were detected in medical workers two times more frequently than in donors (HBsAg in 4.7 and 2.

[Gas-chromatographic analysis of the fungicide azocene in environmental objects and biological specimens].

Sensitive gas chromatography methods have been worked out for evaluation of azocene trace quantities in the air of working and populated area, water, soil, plants and biological material. Chromatographer with thermoionic detector was employed. The lower detection threshold is 2 ng of azocene.

[Gas-chromatographic analysis of dichloropinacoline in the air of the work area and water].

The article narrates on newly developed techniques for the detection of dichlorpinacolin (DCP) in the working zone air. The study was performed on the chromatograph 'Tsvet 164' equipped with a detector of recombination stability (RCS), using Interton-Super as absorbent with phases SE-30.3% (1), OV-17.
