This study is an attempt to evaluate the tissue protective efficacy of isolated flavonoid and hydro-ethanolic extract of Euphorbia neriifolia (HEEN) leaves against N-nitrosodiethylamine (DENA) induced renal carcinoma.
Carcinogenicity was induced in Albino mice by oral administration of DENA (50 mg/kg body weight). The HEEN (150 and 400 mg/kg body weight), Butylated hydroxyanisole (BHA; 0.5 and 1%), and Euphorbia neriifolia flavonoid (ENF; 50 mg/kg body weight) were evaluated for their possible tissue carcinogenesis protective potential.
DENA treated animals showed alterations in normal renal histo-architecture, which comprised of necrosis (N) and vacuolization of the cells. On the other hand, the mice treated with Euphorbia neriifolia lower (ENL) and higher (ENH) dose and ENF before intoxicated with DENA showed that the renal cells were normal (Day 31). Whereas, BHA higher (BHAH) and lower (BHAL) dose failed to diminish the abnormalities caused by DENA.
The findings of the present study Suggested that ENH and ENF showed highest renal-protective activity among all the pretreatments. The results could also be expressed in the order of ENH > ENF > ENL > BHAH > BHAL.
本研究旨在评估大戟叶分离黄酮和乙醇提取物(HEEN)对N-亚硝基二乙胺(DENA)诱导的肾癌的组织保护功效。
通过口服给予DENA(50毫克/千克体重)诱导白化小鼠致癌。评估了HEEN(150和400毫克/千克体重)、丁基羟基茴香醚(BHA;0.5%和1%)以及大戟叶黄酮(ENF;50毫克/千克体重)对组织致癌保护的潜在作用。
DENA处理的动物肾脏正常组织结构出现改变,包括细胞坏死(N)和空泡化。另一方面,在DENA中毒前用大戟叶低剂量(ENL)和高剂量(ENH)以及ENF处理的小鼠,其肾细胞在第31天显示正常。而BHA高剂量(BHAH)和低剂量(BHAL)未能减轻DENA引起的异常。
本研究结果表明,在所有预处理中,ENH和ENF显示出最高的肾脏保护活性。结果也可按ENH > ENF > ENL > BHAH > BHAL的顺序表示。
