Protective effects of ginger toward cadmium-induced testes and kidney lipid peroxidation and hematological impairment in albino rats

Abstract

This study was carried out to investigate the effect of oral dietary supplementation with ginger on cadmium-induced toxic effects on biochemical, hematological, and pathophysiological indices of albino rats. The effect of cadmium and cadmium/ginger treatment on lipid peroxidation was measured by malondialdehyde (MDA) levels in testes and kidney; serum activities of alkaline phosphatase (ALP), acid phosphatase (ACP), and prostatic acid phosphatase (PAP) enzyme were investigated alongside hematological indices. The results showed that cadmium induces a significant increase in both testicular and kidney MDA, whereas cadmium/ginger treatment produced a significant reversal of the effect of lipid peroxidation (P=.004). Cadmium treatment induced 75%, 78%, and 22% increases in activities of ACP, PAP, and ALP, respectively, whereas the cadmium/ginger-treated group reversed these values for enzyme activities (P=.001). Results of organ weight and hematological indices analysis in the cadmium-treated rats showed a decrease in organ weight and distortion of the hemopoietic features, whereas the cadmium/ginger-treated rats showed an improvement in organ weight and hematological indices (P=.04 and .001, respectively). The reversal of the toxic effects of cadmium in the cadmium/ginger-treated albino rats heralds the antioxidant potency of ginger toward cadmium toxicity-associated oxidative stress.
