BUN, blood urea nitrogen; AST, aspartate aminotransferase; ALT, alanine aminotransferase; INR, international normalized ratio; PTT, partial thromboplastin time. Results are expressed as mean ± standard deviation and ^{a, b, c}, p<0.05 is considered significant in Student’s t-test. I, II, III and IV represents group category.
