Adenosine deaminase (ADA) activity was determined in peripheral lymphocytes of 6 patients with HBsAg positive acute viral hepatitis (AVH), 8 patients with HBsAg negative AVH and 12 normal controls. The average of ADA activity in these three groups was 25, 25 and 21 nmoles/min/mg prot. respectively without significance for statistical analysis. However high ADA values (40, 32 and 39) were observed in the peripheral lymphocytes of three patients with AVH.
