Cymbopogon schoenanthus (Ethkher) ameliorates cadmium induced toxicity in swiss albino mice

Cadmium is among the toxic and hazardous metal widely dispersed in the environment in high levels. Current studies have provided new insights into antioxidant properties of bioflavonoid which have emerged as probable therapeutic and nutraceutical agents. The present study is geared to investigate the possible role of Cymbopogon schoenanthus (L.) Spreng. (or Ethkher) on heavy metal cadmium (Cd) induced oxidative stress in mice. Mice were randomly divided into four groups and treated for 15 days as follows: group 1: normal control-treated (saline); group 2: Ethkher leaves extract-treated (100 mg/kg); group 3: cadmium chloride (CdCl₂) treated; group 4: CdCl₂ plus Ethkher leaves extract. The results showed a significant reduction in hemoglobin, RBC and hematocrit in cadmium-treated mice as compared to control. Exposure to Cd caused a significant increase in the number of white blood cells (P < 0.05) indicating the occurrence of systemic inflammation. The results of this study also revealed that the mice intoxicated with Cd showed a significant increase in bilirubin, aspartate aminotransferase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP) and gamma-glutamyl transpeptidase (GGTP) activities. Cd intoxication leads to suppression in humoral immunity. However, pretreatment with Ethkher extract reversed almost all the abnormalities in the blood parameters showing noteworthy protection against cadmium induced toxicity in mice. The outcome of the present study revealed that the Ethkher possessed significant immunomodulatory activity and had a preventive effect on the hematological alterations in Cd intoxicated mice.
