This study was to investigate the relationship between serum inhibitory factor (SIF) activity and natural infection in 81 patients with acute viral hepatitis followed up for one year. 29 females, 52 males, aged 29 to 86 years. A, B and non-A non-B hepatitis were 10, 58 and 13 cases. 5 × 10 -5 monocytes isolated from the peripheral blood of normal blood donors were treated with phytohemagglutinin (10 μg / ml) for 48 hours by adding 20% of the patient’s serum (detection incubation), and the lymphocytes and blood donors Stock serum as a control. Anti-proliferation of lymphocytes
