P. Ladányi - C. Leray: Cytochrome oxidase preparations

oxidase activity (see figure) was found to be 50 to 100 times lower than that of the rat tissues. The degree of cytochrome oxidase activity seems to be in connection with the oxygen supply of the tissues, i.e. with their circulatory conditions. Reference is made to the finding that in the tissues of lower animals containing low cytochrome oxidase activity, a high mucopolysaccharide content was demonstrated (Krompecher et al. 1906).
