Administration of ginger and/or thyme has ameliorative effects on liver and kidney functions of V-line rabbits. - GreenMedInfo Summary

This study was conducted to evaluate the effect of Zingiber officinale and Thymus vulgaris aqueous extracts as a natural antioxidant on liver and kidney functions and antioxidant status of growing rabbits. A total of 24 V-line male rabbits, 3 months old, 1.465 ± 0.12 kg average body weight (BW) were used in a complete randomized design. The rabbits were weighed individually and assigned randomly to four groups (6 animals/each). The first group (G1) was taken fresh water and served as control, rabbits of the second group (G2) weretaken 100 mg/kg BW in drinking water of the Z. officinale aqueous extract daily. The third group (G3) was taken 50 mg/kg BW in drinking water of the T. vulgaris aqueous extract daily and the fourth group (G4) was taken 100 mg/kg BW of the Z. officinale aqueous extract plus 50 mg/kg BW of theT. vulgaris aqueous extract in drinking water daily. The oral administration of ginger and/or thyme aqueous extracts increased (p < .001) serum protein profile compared with control group. Moreover, results of group 2 showed significant (p < .001) decrease in cholesterol, triglyceride and very low-density lipoprotein cholesterol compared with group 3 and 4. Serum urea, uric acid and creatinine levels were significantly (p < .001) decreased in treated groups compared with control group. Oral administration of ginger and/or thyme aqueous extracts to growing rabbits increased (p < .001) total antioxidant capacity and glutathione content and the activity of superoxide dismutase, catalase and glutathione-S-transferase compared with the control group. In conclusion, the current study showed that oral administration of ginger and thyme aqueous extracts to growing rabbits showedno adverse effects on liver and kidney function parameters, histological structures and improved antioxidant status.
