[Examination of behavioral reaction in hyperactive children with attention deficit syndrome using software-hardware systems Binatest and SVET].

The problem of instrumental examination of children with socially important psychoneurological disorders (attention deficit syndrome and hyperactivity) is considered.

[Lactate dehydrogenase isoenzymes in the diagnosis of hepatobiliary diseases].

The total activity of lactatedehydrogenase (Merck tests) and its isoenzymes (electrophoretic fractionation by Helm) were studied in the blood sera of 202 patients with various hepato-biliary diseases (viral hepatitis, chronic persisting and chronic active hepatitis, cirrhosis of liver, chronic cholecystitis, benign cholestasis, malignant formations with and without cholestasis, Gilbert's syndrome and hemolytic jaundice). The referent limits are determined in the sera of 43 clinically healthy subjects (22 females and 21 males). The anaerobic fifth fraction of lactatedehydrogenase (LDH) was most increased in viral hepatitis (about 15 times), in the group with malignant formations with cholestasis (about 2 times) and in benign cholestasis (about 5 times).

[Enzymatic changes in chronic pesticide exposure].

Activity of some enzymes (GOT, GPT, OCT, AP, GGTP, HE) was studied in a group of 74 workers, exposed to professional chronic combined pesticide effects. Enzyme changes were followed up depending on exposure. There was a statistically significant increase in GOT, GPT and OCT activities and decrease in HE.

[Place of serum cholinesterase in the diagnosis of chronic liver diseases].

Serum cholinesterase activity (ChE) was studied in 84 patients with chronic liver diseases (cirrhosis, chronic hepatitis, chronic cholecystocholangiohepatitis, hepatolenticular degeneration). Most pronounced alterations were found in cirrhosis. Significant difference is not established between cardiac and "noncardiac" cirrhosis but is well established between decompensated and compensated cirrhosis.
