Leucine aminopeptidase distribution was examined in the cells of peripheral blood and hemopioetic organs of different Vertebrate classes using histoenzymatic methods. Various degrees of staining intensity were observed in leukocytes of the distinct Vertebrates: in particular, leukocytes of fresh water Osteichthyes and Mammals looked strongly positive, whereas leukocytes of Amphibians, Reptiles, and Birds were barely reactive without great differences among species. The observations should be related to enzyme molecular structure and to kinetics and substrate specificity.
采用组织酶学方法，研究了不同脊椎动物类群外周血和造血器官细胞中的亮氨酸氨肽酶分布。在不同脊椎动物的白细胞中观察到了不同程度的染色强度：特别是，淡水硬骨鱼和哺乳动物的白细胞呈强阳性，而两栖动物、爬行动物和鸟类的白细胞几乎没有反应，不同物种之间差异不大。这些观察结果应与酶的分子结构、动力学和底物特异性相关。
