Gentamicin Induced Damage in Nephrotoxicity and Hepatotoxicity in Male Rabbits: The Protective Effect of Cinnamon

Abstract

One common aminoglycoside antibiotic that is well-known for its ability to treat gram-negative bacterial infections is gentamicin. Its nephrotoxic and hepatotoxic side effects, which are mostly brought about by the production of free radicals that harm kidney and liver cells, frequently restrict its therapeutic application. On the other hand, strong antioxidants found in cinnamon, a popular spice and therapeutic plant, have been demonstrated to have protective properties against oxidative stress. In order to assess the protective role of cinnamon, the current study examines how cinnamon affects gentamicin-induced changes in biochemical markers, liver enzymes in male rabbits. Treatment groups included a control group, a gentamicin-only (GIN) group, a cinnamon-only (CIN) group, and a combined cinnamon-gentamicin (CIN+GIN) group. The results showed that GIN group elevated liver enzymes, specifically aspartate transaminase (AST) and alanine transaminase (ALT), suggesting possible hepatotoxicity. The dose of cinnamon decreased these enzyme levels, while the combination therapy kept the AST levels close to control. Biochemical examination revealed that cinnamon reduced these alterations, particularly in the combination therapy group, while gentamicin increased total protein, urea, and creatinine levels, indicating renal and hepatic stress. The study concludes by highlighting the potential of cinnamon in reducing gentamicin-induced toxicity, specifically through its effects on lipid profiles, liver enzyme activities, body weight, blood profiles, and biochemical markers. This suggests that cinnamon could be used as an adjuvant therapy to reduce the negative effects of gentamicin".
