Protective Effect of Cranberry Extracts against Oxidative Stress and DNA Damage Induced by Diclofenac Sodium in Kidney of Male Albino Rate
Chinese Medicine (CM)
and vit. C (1 g/kg·b·w
orally) on renal toxicity induced by Diclofenac sodium in male albino rats.
Treated rats with diclofenac sodium with a concentration 150 mg/kg·b·w,
expressed a significant increase in several parameters includes, plasma total
cholesterol, LDL-cholesterol, and triglyceride as well as renal nitric oxide
(NO), tumor necrosis
factor-alfa (TNF-α) and TBARS. In
addition, a significant reduction in renal superoxide dismutase (SOD), GSH,
catalase (CAT) and plasma HDL. The present results explain that, using
cranberry extract and vit. C resulted in increasing the level of GSH, CAT and
SOD as well as gene expression of renal SOD, CAT and IL-22 and reduce the level
of TBARs significantly which led to preventing renal tissue damage. Our results also revealed that cranberry
extract can protect DNA from damage as obtained from comet essay. TM-U was
elevated in DCLF treated group when compared with normal. However cranberry
extract was able to reduce this elevation in dose dependant manner.
Histological features in H&E taken to different groups also mirrors this
findings. DCLF causes many changes in renal tissue include infiltration by
inflammatory cells, attenuated glomeruli, apoptosis in tubular epithelia.
