<b>Background and Objective:</b> Cadmium is a heavy metal that has a wide range of applications in human existence. Cadmium may bind to the protein metallothionein and decrease kidney function once it enters the body. The purpose of this study was to investigate the renal protective activity of TVLE against CdCl<sub>2</sub>-induced renal toxicity in rats. <b>Materials and Methods:</b> TVLE was prepared and characterized using instrumental analysis and spectral data. Furthermore, the IC<sub>50</sub> of TVLE against the Vero renal carcinoma cell line was calculated. Adult albino rats were used to assess the renal protective activity of TVLE (150 and 300 mg kg<sup>1</sup> b.wt.) in CdCl<sub>2</sub>-treated rats. <b>Results:</b> IC<sub>50 </sub>of TVLE against Vero cell line equals 148.25 μg mL<sup>1</sup>. The daily oral administration of TVLE at concentrations of 150 and 300 mg kg<sup>1</sup> b.wt. for 21 days to CdCl<sub>2</sub>-treated rates resulted in a significant improvement in tumour volume and tumour weight, urea, creatinine, uric acid, TNF-α, NOx, TBARs, GSH, CAT, SOD, GPx and VEGF-C gene expression in CdCl<sub>2</sub>-treated rats. Furthermore, TVLE almost normalized these effects in renal histoarchitecture. <b>Conclusion:</b> The biochemical, histological and MRI examinations of the current study suggested that TVLE have renal protective activity against CdCl<sub>2</sub>-induced renal toxicity in rats.
镉是一种重金属,在人类生活中有广泛的应用。镉进入体内后会与蛋白金属硫蛋白结合,从而降低肾脏功能。本研究旨在探讨 TVLE 对氯化镉(CdCl2)诱导的大鼠肾毒性的肾保护活性。
采用仪器分析和光谱数据对 TVLE 进行了制备和表征,并计算了 TVLE 对 Vero 肾癌细胞系的 IC50。采用成年白化大鼠评估 TVLE(150 和 300 mg kg1 b.wt.)在 CdCl2处理大鼠中的肾保护活性。
TVLE 对 Vero 细胞系的 IC50为 148.25 μg mL1。每天口服 TVLE 浓度为 150 和 300 mg kg1 b.wt.,连续 21 天,可显著改善 CdCl2处理大鼠的肿瘤体积和肿瘤重量、尿素、肌酐、尿酸、TNF-α、NOx、TBARs、GSH、CAT、SOD、GPx 和 VEGF-C 基因表达。此外,TVLE 几乎使这些作用在肾脏组织形态学上正常化。
本研究的生化、组织学和 MRI 检查表明,TVLE 对氯化镉(CdCl2)诱导的大鼠肾毒性具有肾保护活性。
