Mitochondrial dysfunction at the early stage of cisplatin-induced acute renal failure in rats     

Xie Li-ping  C. Skrezek  H. Wand  F. Reibe 《浙江大学学报(A卷英文版)》2000,1(1):91-96

The present study was undertaken to clarify the pathogenesis of cisplatin-induced acute renal failure at the early stage. Male Sprague-Dawley rats were given an intravenous administration of 10 mg/kg cisplatin. 0.9% saline was infused into them at a rate of 2 ml/h for 3 h, starting with a 2-ml bolus injection before cisplatin administration. 3 h following cisplatin administration, no evident morphological abnormalities were found by both light and electron microscopy; there were also no significant changes in GFR. Thirty min after cisplatin injection, urine sodium and potassium excretion increased by 56% and 260% those of the control animals, respectively. Apparent renal mitochondrial respiration dysfunction was observed in cisplatintreated rats 3 h later; the state 4 respiration increased by 100% and state 3 respiration, respiratory control ratio and carbonyl cyanide p-trifluoromethoxyphenyl hydrazone-uncoupled respiration decreased by 46%, 74% and 47% of the controls, respectively. The present data suggest that mitochondrial dysfunction may be a very early event in cisplatin-induced acute renal failure in rats.  相似文献   

AMINO ACIDS' PROTECTIVE EFFECTS ON EXPERIMENTAL ACUTE RENAL FAILURE     

Xie Li-ping  C. Skrezek  H. Wand 《浙江大学学报(A卷英文版)》2000,1(2):212-217

This study was carried out to elucidate the nephroprotective effects from a mixture of 8 L-amino acids and the possible mechanism of protection by this amino acid mixture. Acute renal failure model was induced by an intravenous administration of 10 mg/kg cisplatin to male Sprague-Dawley rats. A mixture of 8 L-amino acids or 0.9% saline was infused at a rate of 2 ml/h for 3 h, starting with a 2 ml bolus injection before cisplatin administration. Amino acids showed no acute effect on renal morphology. The infusion of a mixture of 8 L-amino acids increased GFR by 85% in control rats. The abnormalities of urine sodium and potassium excretion caused by cisplatin were markedly attenuated by the administration of the amino acid mixture. With the infusion of this amino acid mixture, cisplatin-induced abnormal state 4 respiration returned to control levels and the depressed state 3 respiration, respiratory control ratio and carbonyl cyanide p-trifluoromethoxyphenyl hydrazone-uncoupled respiration were ameliorated remarkably. A mixture of 8 L-amino acids showed marked nephroprotection against cisplatin-induced acute renal failure in rats and might function through augmentation of the cisplatin-injured renal mitochondrial electron transport-oxidative phosphorylation sequence, probably via stabilizing the membrane (including inner mitochondrial membrane) protein tertiary structure. In addition, this amino acid mixture remarkably increased GFR and decreased urine sodium excretion in rats.  相似文献   

"内化",一个被忽略的关键环节--大学生素质教育问题浅析     

谢斌 《辽宁教育研究》1999,(2):95-97

近年来大学生素质教育开展得轰轰烈烈,然而其效果却并不如人们所预期的那样好,恐怕与大学忽略了素质教育过程中“内化”这一关键环节不无关系。在某种程度上我们甚至可以说,大学教育缺乏促进素质教育要求转化为学生内在身心素质的条件与措施,是大学生素质教育功亏一篑...  相似文献   

对盐类水解反应规律的再思考     

文庆城  谢美珍  邹静 《中小学实验与装备》2006,16(5):16

水解反应规律:有弱才水解,无弱不水解,弱弱双水解,谁强显谁性,都弱具体定.其中"弱弱双水解"是指弱酸根离子与弱碱根离子的水解相互促进,发生双水解反应,那么弱酸根离子与弱碱根离子相遇是否一定发生双水解反应呢?  相似文献
