Abstract
  1. After allyl formate (AF) was administered to the rats, the existence of semicarbazide-sensitive amine oxidase (SSAO) in rat identified. 2. When the heart homogenate and plasma of AF-administered rat were pretreated with 10(-3) M clorgyline and deprenyl, the Km value for benzylamine of rat heart was same as the value of plasma. 3. The existence of SSAO in plasma of AF-administered rats were identified by IEF-gel electrophoresis. The pI values of SSAO in heart and plasma were a single peak of 5.0. 4. SSAO released from the rat heart in response to AF, although the other origins of this enzyme are unknown.
摘要
  1. 将甲酸烯丙酯(AF)给予大鼠后,在大鼠体内鉴定出了氨基脲敏感胺氧化酶(SSAO)的存在。2. 当用10⁻³ M的氯吉兰和司来吉兰预处理给予AF的大鼠的心脏匀浆和血浆时,大鼠心脏中苄胺的Km值与血浆中的值相同。3. 通过IEF-凝胶电泳鉴定了给予AF的大鼠血浆中SSAO的存在。心脏和血浆中SSAO的pI值为单一峰值5.0。4. 尽管该酶的其他来源尚不清楚,但AF会使大鼠心脏释放出SSAO。
