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 (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 (CdCl) treated; group 4: CdCl 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 ( < 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.
镉是广泛散布于环境中的有毒有害金属之一,其含量很高。目前的研究为生物类黄酮的抗氧化特性提供了新的见解,生物类黄酮已成为可能的治疗和营养保健剂。本研究旨在探讨(L.)Spreng(或Ethkher)对重金属镉(Cd)诱导的小鼠氧化应激的可能作用。将小鼠随机分为四组,并按以下方式处理15天:第1组:正常对照组(生理盐水处理);第2组:Ethkher叶提取物处理组(100毫克/千克);第3组:氯化镉(CdCl)处理组;第4组:CdCl加Ethkher叶提取物处理组。结果显示,与对照组相比,镉处理小鼠的血红蛋白、红细胞和血细胞比容显著降低。接触镉导致白细胞数量显著增加(<0.05),表明发生了全身炎症。本研究结果还显示,镉中毒的小鼠胆红素、天冬氨酸转氨酶(AST)、丙氨酸转氨酶(ALT)、碱性磷酸酶(ALP)和γ-谷氨酰转肽酶(GGTP)活性显著增加。镉中毒导致体液免疫受到抑制。然而,用Ethkher提取物预处理几乎逆转了血液参数中的所有异常,显示出对小鼠镉诱导毒性的显著保护作用。本研究结果表明,Ethkher具有显著的免疫调节活性,对镉中毒小鼠的血液学改变具有预防作用。
