Comparison of the Protective Effect of Salvia officinalis and Rosmarinus officinalis Infusions Against Hepatic Damage Induced by Hypotermic-Ischemia in Wistar Rats.

We aimed to evaluate, in this study, the effect of Rosmarinus officinalis L. and Salvia officinalis L. in the amelioration of liver hypothermic conservation in male wistar rats. Livers from each rat were collected and preserved for 24 h at 4 degrees C in a Krebs solution with or without increasing doses of sage or rosemary infusions (25, 50, and 100 mg/mL). Liver hypothermic conservation induced a decrease in the activity of superoxide dismutase, catalase, and glutathione peroxidase and a significant increase in lipid peroxidation. S. officinalis L. infusion at 25 mg/mL normalized this oxidative disturbance but appears toxic at 50 and 100 mg/mL due to the presence of large amount of pyrogallol which contribute to the cytoplasmic alteration of hepatocytes. The addition of different doses of R. officinalis L. infusion induced an increase in catalase and glutathione peroxidase activities and a decrease in lipid peroxidation with an amelioration of cellular architecture. In conclusion, increasing doses of R. officinalis L. infusion protect against hepatic hypotermic-ischemia while S. officinalis L. infusion could have an hepatoprotective role when administrated at lower dose.
