The Metabolism of Retina

SIGNIFICANT differences of the normal metabolism of tissues either in Ringer bicarbonate or in phosphate solution have so far not been reported1,2. On the other hand, the contradictory results obtained by Dixon and Elliot3 and Alt4 respectively concerning the hydrogen cyanide stable residue of the respiration of liver slices have been explained by the use of different media. Nearly complete inhibition occurs in Ringer bicarbonate while a considerable residue remains in phosphate solution or in Ringer without bicarbonate.
