MMP2 and animal viral hepatitis: Additionally, serum MMP2 showed significantly decreased activity not only in viral hepatitis (313.17 ± 90.39 ng/mL, p = 0.0002) and viral cirrhosis (332.01 ± 47.4 ng/mL, p = 0.0004) but also in alcoholic hepatitis (306.41 ± 49.45 ng/mL, p < 0.0001) and alcoholic cirrhosis (326.43 ± 54.87 ng/mL, p = 0.0004) when compared to normals.
