摘要(Abstract)：

为了探讨体内亚硫酸氧化酶的分布特点及随年龄的变化规律,以Wistar大鼠为实验材料,研究了不同月龄大鼠脏器中的亚硫酸氧化酶活性.以细胞色素C为电子受体,应用分光光度法测定了不同月龄(1、4、10个月)大鼠肝、肾、肺、脾、脑、胃及胸主动脉中亚硫酸氧化酶的活性.结果表明:1)亚硫酸氧化酶在大鼠全身主要脏器中普遍存在,且在不同脏器中该酶的活性不同,从强到弱的顺序基本表现为:肝、肾>胃>脑>胸主动脉血管>肺>脾;2)肝、肾、血管组织中亚硫酸氧化酶活性与大鼠年龄相关,肝脏亚硫酸氧化酶活性随年龄的增加而增加(Spearman,r=0.674,p<0.001),而肾脏和胸主动脉血管该酶活性随年龄的增加而减小(Spearman,r=-0.756,p<0.001;r=-0.629;p<0.05),其余脏器未见明显变化;3)亚硫酸氧化酶活性降低可能是一种机体衰老的生化标志物.
