[Relation of changes in plasma cAMP, cGMP and the clinical conditions, pathology and the type of traditional Chinese medicine in 50 cases of chronic severe icteric hepatitis].

Plasma of cAMP and cGMP in 30 cases of chronic active hepatitis (group of cholestatic patients) as well as in 20 cases of chronic hepatitis with submassive or massive necrosis (group of chronic severe hepatitis patients) were studied with 125I-marked radioimmunoassay. 50 cases with their serum bilirubin levels higher than 171 mumol/L were selected as subjects for this study. Among them, 42 were diagnosed as hepatitis B, 6 as coinfection of hepatitis A and B. According to differentiation of symptoms and signs of TCM, 24 were diagnosed as simple hepatitis due to blood stasis and blood heat, 17 as hepatitis due to blood stasis and blood heat accompanying symptoms of Yang deficiency of the Spleen and Kidney. 20 healthy persons were selected as controls. The results were as follows: cAMP was 56.82 +/- 25.54 ng/L and 80.32 +/- 20.73 ng/L, and cGMP was 9.07 +/- 6.56 ng/L and 19.49 +/- 9.34 ng/L in the group of cholestatic patients and in the group of chronic severe hepatitis patients respectively. Both were higher than those in the control group whose cAMP was 14.12 +/- 3.25 ng/L and cGMP was 5.87 +/- 1.44 ng/L (P less than 0.01). Increase in cGMP and decrease in the ratio of cAMP and cGMP in the cases accompanying symptoms of Yang deficiency of the Spleen and Kidney were much higher than those in the other two types of hepatitis patients (P less than 0.01 and 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
