The present report deals with the histo-enzymological mapping of adenosine triphosphatase and simple esterase in the diencephalon and mesencephalon of Uromastix hardwickii. The enzymatic make-up, in both cases, does not differ markedly in the various nuclei; few variations, of course, occur in some midbrain areas like pretectal nuclei. The latter are intensely positive for ATPase, while these nuclei are moderate to simple esterase. Nevertheless, one of the most interesting results pertaining to simple esterase activity is of a high order in the fiber tracts in comparison to ATPase. The other interesting feature relates to the fact that generally intensely positive nuclei, in ATPase preparations, are those which have extensive efferent fibres. The metabolic significance of high degree of ATPase activity vis-a-vis extensive efferent connections has been exhaustively discussed, besides the possible significance of the general data obtained.
本报告阐述了硬尾蜥双脑和中脑三磷酸腺苷酶及简单酯酶的组织酶学图谱。在这两种情况下，不同核团的酶组成并无显著差异；当然，在一些中脑区域如顶盖前核会出现一些变化。后者对三磷酸腺苷酶呈强阳性反应，而这些核团对简单酯酶呈中度阳性反应。然而，与三磷酸腺苷酶相比，与简单酯酶活性相关的最有趣结果之一是在纤维束中处于较高水平。另一个有趣的特征是，在三磷酸腺苷酶制剂中，通常呈强阳性的核团是那些具有广泛传出纤维的核团。除了所获得的一般数据可能具有的意义外，还详尽讨论了三磷酸腺苷酶高活性与广泛传出连接之间的代谢意义。
