Abstract

The activities of rhodanese and beta-mercaptopyruvate sulfurtransferase (MST) in different organs of sheep and cattle were measured. 2. Liver, kidney, omasum, and rumen were the richest sources of both enzymes. The activities of both enzymes in other organs of the sheep and the cattle decreased in the order of lung, brain, heart, abomasum, lymph node, urinary bladder, spleen, and the skeletal muscle. 3. The activities of both enzymes in most organs of the sheep were higher than the cattle. 4. Both enzymes showed higher activities in the epithelial layers than the muscular layers of rumen, omasum and reticulum. 5. In most of the tissues of both species the level of rhodanese activity was greater than MST.

摘要

测定了绵羊和牛不同器官中硫氰酸酶和β-巯基丙酮酸硫转移酶（MST）的活性。2. 肝脏、肾脏、重瓣胃和瘤胃是这两种酶最丰富的来源。绵羊和牛其他器官中这两种酶的活性按肺、脑、心脏、皱胃、淋巴结、膀胱、脾脏和骨骼肌的顺序降低。3. 绵羊大多数器官中这两种酶的活性高于牛。4. 在瘤胃、重瓣胃和网胃的上皮层中，这两种酶的活性均高于肌肉层。5. 在这两个物种的大多数组织中，硫氰酸酶的活性水平高于MST。
