Abstract

Succinic dehydrogenase (SDH) and adenosine triphosphatase (ATPase) activity measured 21 days after 3 intraperitoneal injections of di-2-ethylhexyl phthalate (DEHP) was decreased in heart, lung and kidney while it remained unaltered in brain. Under in vitro conditions, only SDH was sensitive to DEHP, degree of inhibition being concentration-dependent. DEHP solubilized with Tween 80 inhibited the SDH activity significantly at small concentrations of 5 to 25 ppm. ATPase activity was not modified.

摘要

在腹腔注射邻苯二甲酸二(2-乙基己基)酯(DEHP)三次后21天测量,心脏、肺和肾脏中的琥珀酸脱氢酶(SDH)和三磷酸腺苷酶(ATPase)活性降低,而大脑中的活性保持不变。在体外条件下,只有SDH对DEHP敏感,抑制程度呈浓度依赖性。用吐温80增溶的DEHP在5至25 ppm的低浓度下显著抑制SDH活性。ATPase活性未改变。
