BackgroundMorphine is commonly used to treat severe pain. This substance is significantly metabolized in the liver and causes disturbing effects. Genistein is an isoflavone and has antioxidant properties. The aim of this study was to evaluate the effects of genistein against morphine damages on mouse liver.MethodsBetween May 2017 and March 2018, 48 male mice were divided into six groups (n = 8 in each group). Various doses of genistein (25 and 50 mg/kg) and morphine plus genistein (25 and 50 mg/kg) were administered intraperitoneally to 48 male mice for 20 consequent days. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), serum nitric oxide (NO) levels, liver weight, and the diameter of hepatocytes and central hepatic vein were studied and compared using one-way analysis of variance.ResultsMorphine administration significantly increased the mean diameter of the central hepatic vein (22.76 ± 1.9 μm vs. 15.04 ± 0.60 μm, χ2 = 21.814, P = 0.001) and hepatocytes (3.03 ± 0.10 μm vs. 1.10 ± 0.05 μm, χ2 = 9.873, P = 0.001) respectively, blood serum NO level (38.00% ± 2.09% vs. 18.72% ± 4.40%, χ2 = 20.404, P < 0.001), liver enzyme level (AST: 111.80 ± 5.10 ng/ml vs. 81.93 ± 2.20 ng/ml, χ2 = 32.201, P < 0.0001; ALT: 45.14 ± 4.10 ng/ml vs. 35.49 ± 2.50 ng/ml, χ2 = 18.203, P < 0.0001; and ALP: 3.28 ± 0.20 ng/ml vs. 2.14 ± 0.10, χ2 = 5.04, P < 0.0001, respectively), and decreased liver weight (18.50 ± 0.90 g vs. 27.15 ± 0.50 g, χ2 = 22.415, P = 0.001) compared to saline group (0.535-0.750, P < 0.0001). However, administration of genistein plus morphine significantly enhanced liver weight (25 mg/kg: 21.15 ± 2.13 g vs. 18.50 ± 0.90 g, χ2 = 19.251, P < 0.0001; 50 mg/kg: 21.20 ± 1.00 g vs. 18.5 ± 0.9 g, χ2 = 19.502, P < 0.0001, respectively) and reduced the mean diameter of hepatocyte (25 mg/kg: 2.17 ± 0.30 μm vs. 3.03 ± 0.10 μm, χ2 = 22.780, P = 0.001; 50 mg/kg: 2.01 ± 0.20 μm vs. 3.03 ± 0.10 μm χ2 = 7.120, P = 0.001, respectively), central hepatic vein (25 mg/kg: 19.53 ± 1.00 μm vs. 22.76 ± 1.90 μm, χ2 = 20.681, P = 0.001; 50 mg/kg: 19.44 ± 1.20 μm vs. 22.76 ± 1.90 μm, χ2 = 18.451, P = 0.001, respectively), AST (25 mg/kg: 95.40 ± 5.20 ng/ml vs. 111.80 ± 5.010 ng/ml, P < 0.0001; 50 mg/kg: 90.78 ± 6.00 ng/ml vs. 111.80 ± 5.10 ng/ml, χ2 = 17.112, P < 0.0001, respectively), ALT (25 mg/kg: 35.78 ± 5.01 ng/ml vs. 45.14 ± 4.10 ng/ml, χ2 = 15.320, P < 0.0001; 50 mg/kg: 33.78 ± 2.60 ng/ml vs. 45.14 ± 4.10 ng/ml, χ2 = 14.023, P < 0.0001, respectively), ALP (25 mg/kg: 2.35 ± 0.30 ng/ml vs. 3.28 ± 0.20 ng/ml, χ2 = 4.101, P < 0.0001; 50 mg/kg: 2.34 ± 0.10 ng/ml vs. 3.28 ± 0.20 ng/ml, χ2 = 2.033, P < 0.0001, respectively), and NO levels (25 mg/kg: 25.92% ± 2.30% vs. 38% ± 2.09%, χ2 = 17.103, P < 0.0001; 50 mg/kg: 24.74% ± 4.10% vs. 38% ± 2.09%, χ2 = 25.050, P = 0.001, respectively) compared to morphine group.ConclusionIt seems that genistein administration might improve liver damages induced by morphine in mice.
