Nephroprotective effect of ethanol extract Abelmoschus manihot l. Leaves in gentamicin-induced mice

Nephrotoxicity is the most common side effect of gentamicin, an aminoglycoside antibiotic group. It was mediated by oxidative stress mechanisms. Abelmoschus manihot L. leaves (AML) have antioxidant activity flavonoids. This study aims to determine the nephroprotective effect of AML in gentamicin-induced nephrotoxicity using mice models. It conducted an experimental design study in a pharmacology laboratory using mice models. It was conducted experimentally in 7 groups. There are normal, solvent, negative control, and four test groups (given an ethanolic extract of AML at doses of 50, 100, 200, and 400 mg/kgBW) which were administered orally for 7 days. Gentamicin 112 mg/kgBW was induced intraperitoneally on the 8th day. All mice were anesthetized on the 11th day to collect blood serum and renal organs for further examination. The data were analyzed using SPSS version 26 for One Way ANOVA test and followed by Duncan's post-hoc analysis test. The difference is considered significant if the p-value <0.05. Gentamicin successfully induced renal damage based on increasing creatinine and blood urea nitrogen (BUN) levels. This was by histopathology analysis which showed renal necrosis in the negative control group. Ethanolic extract of AML prevents nephrotoxicity due to gentamicin in a dose-dependent manner in creatinine level but not in BUN and histopathology. However, taken together all results showed that ethanol extract of AML has a nephroprotective effect in gentamicin-induced nephrotoxicity.
