✦ Synopsis

The Effect of Ribonucleinase on Succinic Dehydrogenase and Cytochrome Oxidase. --CHARLES A. ZITTLE. Succinic dehydrogenase has been shown by E. Adler, H. yon Euler and B. Skarzynski (Arkiv fiir Kemi, Mineralogi och Geologi, ITA, No. 2, 1943) to be inhibited by yeast adenylic acid and adenosine, an observation which has been confirmed in this laboratory (C. A. Zittle, to be published). This behavior of succinic dehydrogenase suggested that the finding of V. R. Potter and H. G.

Albaum (Journal of General Physiology, 26: 443, 1943) that succinic dehydrogenase and cytochrome oxidase were inhibited by ribonucleinase, although interprepted as indicating a loss of essential structure by the action of the rlbonucleinase, might have resulted from the formation of nucleotides in inhibitory amounts by the action of ribonucleinase on the nucleic acid which is present.

The enzymes for the investigation of the above hypothesis were prepared from pig hearts by the method of D. Keilin and E. F. Hartree

Fink ( '25) studied the respiratory metabolism of the Japanese beetle egg at temperatures between 21" and 24Β°C. He found that at these temperatures, the respiratory rate remained low during the first 6 days and then increased rapidly. He called the first 6 days of the embryonic period the "formative

## Abstract Brain mitochondrial cytochrome oxidase and respiratory activities were compared after __in vivo__ and __in vitro__ exposure to cyanide. For the __in vivo__ studies, mice were exposed to a non‐lethal (4 mg kg^βˆ’1^) or lethal (20 mg kg^βˆ’1^) dose of KCN. From these mice, purified brain mito
