    Abstract:
    OBJECTIVE: To investigate nitric oxide (NO) and nitric oxide synthase (NOS) in patients with chronic hepatitis B. METHODS: Nitric oxide and nitric oxide synthase, including inducible NOS (iNOS) and constitutive NOS (cNOS), were measured in patients and control groups, then were statistically analyzed. RESULTS: NO and iNOS were significantly higher in patients with hepatitis B than in the controls (P < 0.05). NO and iNOS were significantly higher in patients with increased ALT than in the controls and in patients with normal ALT (P < 0.05). NO was significantly higher in patients with normal ALT than in the controls (P < 0.05). cNOS were not significant different among these groups. NO and iNOS significantly correlated with ALT in patients with hepatitis B (r=0.367 and r=0.474). No significant relationship was found among NO, NOS and HBV DNA. Among different genotype groups, NO and NOS had no significant difference. CONCLUSION: NO and NOS were higher in patents with chronic hepatitis B. In patients with increased ALT, NO's damage was severe. In patients with normal ALT, there was no significant damage caused by NO. NO should be detected in patients with hepatitis B in addition to HBV markers.
