Abstract

Aim: The aim of this study was to evaluate the protective effect of curcumin-rich turmeric (CRT) extract against isotretinoin (ISO)-induced liver damage through routine biochemical parameters and oxidative stress parameters that indicate liver damage.

Material and method: 42 albino Wistar rats of 200 g were randomly grouped as Group I: Healthy control, Group II: Sunflower oil, Group III: Curcumin 200 mg/kg, Group IV: ISO control groups (7.5 mg/kg), Group V: Curcumin 50 mg/kg + ISO 7.5 mg/kg, Group VI: Curcumin 100 mg/kg + ISO 7.5 mg/kg, Group VII: Curcumin 200 mg/kg + ISO 7.5 mg/kg. At the end, after the rats were killed, their blood and liver tissues were collected. ALT and AST levels in serum; superoxide dismutase activity (SOD), GSH, and MDA levels in liver tissue were determined.

Results: Our results showed that ALT, AST, and MDA levels increased, and SOD and GSH levels decreased in the ISO-administered group compared to the healthy control group. CRT 50, 100, and 200 mg/kg groups were compared to ISO group. A dose-dependent increase in protective effect was observed. A decrease in ALT, AST, and MDA levels, and an increase in SOD and GSH levels were determined. A protective effect was found at all doses. The best protective effect was in the CRT 200 mg/kg group.

Conclusion: CRT extract can be considered a candidate herbal medicine for the elimination of liver damage in individuals using ISO. However, further experimental and clinical validation should be studied.

Keywords: Isotretinoin; curcumin; liver toxicity; oxidative stress; turmeric.
