Evaluation of nitric oxide (NO) levels in hepatitis C virus (HCV) infection: relationship to schistosomiasis and liver cirrhosis among Egyptian patients.

Nitric oxide (NO), a recently discovered free radical, is overproduced in liver cirrhosis. Hepatitis C virus (HCV) might increase NO levels via increased inducible NO synthase (iNOS). This work was carried out to study the effect of HCV-induced liver cirrhosis on NO levels among Egyptian patients.
