Phenylene Diamine

By synthesizing an analogue of N,N-dimethyl-p-phenylene diamine, a new reagent for the Nadi reaction was found which provided a useful histochemical method for either cytochrome oxidase (G-Nadi) or peroxidase (M-Nadi). The new agent is 4-amino-1-N,N-dimethylnaphthylamine and yields with α-naphthol, an indonaphthol purple pigment which is more stable and more satisfactorily distributed in tissue than the indophenol blue of the Nadi reaction. Thin sections may be used, some permanence of color is obtained and the granules are fine and anatomically distributed. The localization of cytochrome oxidase activity in heart, stomach, spleen, and cerebellum of the rat is described.

Plant Respiration

Spadix tissue of a number of aroid species has been shown to be an outstanding exception to the general pattern of plant respiration. In the work reported here the respiration of whole tissue and mitochondria from the spadix of another aroid species Zantedeschia aethiopica Spreng. was studied. The respiration of both whole tissue and mitochondria was found to be strongly inhibited by the metal-complexing agents cyanide and azide. Cytochrome oxidase and cytochromes band c were spectroscopically indentified in mitochondrial suspensions and cytochrome oxidase activity was demonstrated in extracts. The results indicate that the respiratory characteristics of the Zantedeschia spadix tissue are similar to those of most other plant tissues. Such characteristics are, however, in marked contrast to the respiratory pattern reported for other aroid spadices.
