Abstract

We investigated the effects of ecstasy on the expression of heat shock protein 70 (HSP70) and apoptosis in rat kidney. We used 20 adult male Wister rats divided into four groups of five: control, sham, Ecs 5 and Ecs 10; the latter two groups were administered by intraperitoneal (i.p.) injection 5 and 10 mg/kg ecstasy, respectively. At the end of the experiment, the kidneys were removed, fixed, and prepared for immunohistochemistry and TUNEL staining to evaluate the expression of HSP70 and apoptosis, respectively. HSP70 expression and apoptosis cells were significantly increased in most parts of the kidneys, and kidney weight and volume were decreased in rats administrated 10 mg/kg ecstasy compared to the control group. Administration of 5 mg/kg ecstasy significantly increased HSP70 expression in the distal and collecting tubules and the number of TUNEL-positive cells in the proximal, distal convoluted tubules and renal corpuscles compared to the control group. We found that ecstasy increases HSP70 expression and apoptosis in renal tissue.

摇头丸对大鼠肾热休克蛋白表达及细胞凋亡的影响。
研究了摇头丸对大鼠肾组织热休克蛋白70 (HSP70)表达及细胞凋亡的影响。我们将20只成年雄性Wister大鼠分为4组,每组5只:对照组、假手术组、Ecs 5组和Ecs 10组;后两组小鼠分别腹腔注射摇头丸5 mg/kg和10 mg/kg。实验结束后,取肾固定,制备免疫组织化学和TUNEL染色,分别检测HSP70和凋亡的表达。与对照组相比,10 mg/kg摇头丸组大鼠肾脏大部分部位HSP70表达和凋亡细胞显著增加,肾脏重量和体积减小。与对照组相比,给药5 mg/kg摇头丸显著增加大鼠肾小管远端和收集小管中HSP70的表达以及近端、远端曲小管和肾小体中tunel阳性细胞的数量。我们发现摇头丸增加了肾组织中HSP70的表达和凋亡。

期刊介绍: Biotechnic & Histochemistry (formerly Stain technology) is the official publication of the Biological Stain Commission. The journal has been in continuous publication since 1926. Biotechnic & Histochemistry is an interdisciplinary journal that embraces all aspects of techniques for visualizing biological processes and entities in cells, tissues and organisms; papers that describe experimental work that employs such investigative methods are appropriate for publication as well. Papers concerning topics as diverse as applications of histochemistry, immunohistochemistry, in situ hybridization, cytochemical probes, autoradiography, light and electron microscopy, tissue culture, in vivo and in vitro studies, image analysis, cytogenetics, automation or computerization of investigative procedures and other investigative approaches are appropriate for publication regardless of their length. Letters to the Editor and review articles concerning topics of special and current interest also are welcome.
