A cytochemical study of mitochondria of Hymenolepis diminuta indicates the presence of a mitochondrial peroxidase. Utilizing a 3,3'-diaminobenzidine (DAB) medium at pH 9.7, the reaction product is localized in the intracristal space, and between the inner and outer membranes of the mitochondria. No inhibitory effects are exerted on the peroxidase reaction by cyanide, azide, or aminotriazole. In addition, the mitochondria appear to have an enzyme which is cytochemically similar to vertebrate cytochrome c-oxidase. The possible physiological significance of the peroxidase is discussed.
微小膜壳绦虫线粒体的细胞化学研究表明存在一种线粒体过氧化物酶。在pH 9.7的3,3'-二氨基联苯胺（DAB）培养基中，反应产物定位于线粒体内嵴间隙以及线粒体内外膜之间。氰化物、叠氮化物或氨基三唑对过氧化物酶反应无抑制作用。此外，线粒体似乎有一种在细胞化学性质上与脊椎动物细胞色素c氧化酶相似的酶。文中讨论了过氧化物酶可能的生理意义。
