[The ultrasonic diagnosis of lesions of the hepatobiliary system in protracted forms of viral hepatitis in children].

Ultrasound examination of the hepatobiliary system was carried out in 102 children (3-12 years) with viral hepatitis A and B on the 57-75 days of the disease. Increased liver size and swelling of the parenchyma was revealed in 100% of patients. Thickening of the gallbladder walls was similarly frequent in A and B hepatitis.

[The significance of the content of connective tissue metabolites in the blood serum for the diagnosis of chronic viral hepatitis and liver cirrhosis].

With the purpose of improving early clinico-biochemical diagnosis of viral chronic active hepatitis and liver cirrhosis in children, the authors used indices of connective tissue metabolism--determination of free oxiprolin and neutral lipids in the blood serum. High levels of free oxiprolin and neutral lipids were revealed in patients with chronic active hepatitis and low--in liver cirrhosis. These data characterize different reactions of the connective tissue in the named diseases determined by different morphological maturity grades and secretory activity of fibroblasts.

[The effect of leukocyte interferon on the kinin system indices of the blood in patients with acute intestinal infections].

The authors studied the efficiency of using rectally interferon in acute intestinal infections, the influence of the agent on the kinin system in these patients. 42 children with bacterial intestinal infections were examined. They were given rectally 1000 IU of interferon.
