Abstract

This study examines the activities of alanine aminotransaminase (ALT) and aspartate aminotransferase (AST) in the liver of 30 adult Wistar rats exposed to nutmeg for 30 days. 1 g of nutmeg was administered to group A (n=10), 2 g of nutmeg to group B (n=10) and group C (n=10) was used as the control. Enzyme activities were assayed in both serum and liver (tissue homogenate) spectrophotometrically. Results obtained showed a significant increase (p < 0.05) in level of AST in serum of rats in group A and B (20.2±7.29 and 23.2 ± 3.27 U/L) when compared to the control group (14.8± 1.78 U/L) while serum ALT level was significantly reduced (5.2± 1.78 and 4.2 ± 0.04 U/L) compared to the control group (7.0 ± 2.6 U/L) but the differences based on dosage was statistically insignificant (p≥ 0.05). The enzyme activities in liver tissue homogenate showed a significant increase (p˂ 0.05) in AST levels (13.8 ± 1.14, 14.6 ± 1.78 and 12.8 ± 0.08 U/L) among test groups and between controls but ALT levels though lower in treated groups than control, was statistically insignificant (p≥ 0.05) among test and between control group (4.6 ± 1.34, 4.0 ± 0.08 and 5.8 ± 0.03 U/L). Differences in enzyme activities due to nutmeg administration may lead to hepatocellular injury as well as myocardial infarction. The results suggests that dosage and long-term consumption of nutmeg could have severe health implication as it affects liver function as well as other associated organ of the body.
