[The microcirculatory function in the chronic HBs-antigen carrier state].

The authors discuss the problem of widely spread chronic carrier state of HBs-antigen by healthy persons. The majority of antigen carriers show both moderate clinico-biochemical and ultrasonic signs of chronic liver involvement, and different disorders of the microcirculation which are formed in conditions of prolonged persistence of the virus of B hepatitis in the body. Early diagnosis of generalized disorders of the terminal blood circulation in antigen carriers may be useful in the determination of pathogenetically substantiated treatment tactics and prognostication of unfavourable outcomes of chronic HBs-antigen carrier state in preclinical period of the disease.

[Unresolved questions on the diagnosis of hepatitis in donors].

Clinico-laboratory characteristics of liver lesions occurring in 64 immune donors of blood plasma of 0(1) group are presented. The diseases ran as subclinical, latent, anicteric forms of hepatitis, and only in 5 persons as acute icteric hepatitis. In 50% of the patients there were signs of the disease becoming chronic: long-term increase in the blood serum of the activity of alanine aminotransferase, alkaline phosphatase, variations in bilirubin levels.

[Role of carriers of the hepatitis B surface antigen as possible sources of infection in children's collectives].

The complex clinico-epidemiological and laboratory surveys of the children and the staff in 71 institutions for children of preschool age were made at the period of increased viral hepatitis morbidity in these institutions, and the dynamic observations of 11 children's institutions having children with prolonged HBs-antigenemia were carried out. In the foci of viral hepatitis the level of antigenemia in the children and the staff exceeded (p less than 0.01) that in the control group.
