Extracts of (CA) have been reported to possess medicinal properties ranging from potential hepatoprotective, anti-diabetic, and anti-cardiovascular. In our previous study, gas chromatography mass spectroscopy check of CA extract showed the inclusion of 2,4-bis(1,1-dimethylethyl)-phenol, a phenolic phyto-compound that constitutes about 45 %, carotene and linoleic acid sources, and silicon-rich components. Hence we compare the preventive and ameliorative potentials of CA with ascorbate in dimethyl nitrosamine (DMN)-induced renal toxicity and sperm abnormalities in rats. Renal toxicity was investigated by quantifying the levels and activities of endogenous antioxidant parameters. Renal damage marked by significant reduction in GSH level, as well as significant elevation in MDA concentration, and activities of GPx, GST, CAT, and SOD were restored after the intervention of CA and ascorbate. Also, there was decrease in live sperm, sperm concentration, sperm gross and individual motility, and normal sperm morphology, following DMN administration. Based on the gathered results, it is concluded that ascorbate and CA demonstrate comparable ameliorative and protective effects against DMN-induced renal and testicular toxicities in rats.
(CA)提取物已被报道具有多种药用特性,包括潜在的肝脏保护、抗糖尿病和抗心血管作用。在我们之前的研究中,对CA提取物进行气相色谱 - 质谱分析发现其中含有2,4 - 双(1,1 - 二甲基乙基) - 苯酚,这是一种酚类植物化合物,约占45%,还有胡萝卜素和亚油酸来源以及富含硅的成分。因此,我们比较了CA与抗坏血酸对大鼠二甲基亚硝胺(DMN)诱导的肾毒性和精子异常的预防及改善潜力。通过量化内源性抗氧化参数的水平和活性来研究肾毒性。在CA和抗坏血酸干预后,以谷胱甘肽(GSH)水平显著降低以及丙二醛(MDA)浓度、谷胱甘肽过氧化物酶(GPx)、谷胱甘肽 - S转移酶(GST)、过氧化氢酶(CAT)和超氧化物歧化酶(SOD)活性显著升高为特征的肾损伤得到了恢复。此外,给予DMN后,活精子数量、精子浓度、精子总体和个体活力以及正常精子形态均有所下降。根据收集到的结果得出结论,抗坏血酸和CA对DMN诱导的大鼠肾毒性和睾丸毒性具有相当的改善和保护作用。
