RESUMO
Inflammatory bowel disease is associated with multiple extraintestinal disorders, including hepato-nephrological disruptions. The aim of this study was to evaluate the hepato-nephroprotective effect of Salvia officinalis leaf decoction extract (SLDE) on acetic acid (AA)-induced colitis accompanied with liver and kidney injuries. Wistar albinos rats were pretreated with SLDE (50, 100, and 200 mg kg-1, b.w., p.o.) during 10 days and intoxicated for 24 h by acute rectal administration of AA (3%, v/v, 5 mL kg-1, b.w.). Our results showed that S. officinalis treatment protected against AA-induced liver and kidney injuries by plasma transaminase activities and preservation of the hepatic and renal tissue structures. The level of high-density lipoprotein-cholesterol was also reverted back to near normalcy by treatment. Lipid peroxidation was decreased significantly by officinal sage supplementation. Treatment with SLDE increased enzymatic (superoxide dismutase, catalase, and glutathione peroxidase) and nonenzymatic (-SH groups and reduced glutathione) antioxidants in liver and kidney tissues. Also, SLDE treatment significantly protected against inflammation markers and reversed all intracellular mediator perturbations. This study suggests that the S. officinalis has a beneficial effect in controlling kidney and liver injuries by reducing lipid peroxidation and increasing antioxidant enzyme activities and nonenzymatic contents, which reduce the risk of developing extraintestinal complications.
