無カタラーゼ血液症患者の赤血球代謝に関する実験的研究 第2編 無カタラーゼ血液症患者及び健康人の赤血球酸素消費に及ぼす数種物質の影響

By examining the influences of protoporphyrin and of four kinds of metal ions, namely, those of iron, zinc, magnesium, and manganese, and the influences of glucose, lactate, glycerophosphate, acetate, pyruvate, glutamate, succinate, fumarate, malate, and aspartate, methylene blue and DPN, on the oxygen consumption of erythrocytes both in acatalasemia patients and the normal, and by further spectroscopic studies on the changes of the hemoglobin accompanying the respiration of erythrocytes when malate and aspartate of these had been used as substrates, the author reached the following conclusions: namely, in the respiration of erythrocytes of these patients as compared with the normal, no marked difference other than a comparatively weaker enzymatic action of malic dehydrogenase and the enzymes concerning aspartic acid oxidation can be recognized; and as for the disposal of small amounts of H(2)O(2) supposedly to be liberated during respiration of erythrocytes, the compensation by peroxidase, hemoglobin, or other hemin proteins may be thought to be sufficient.
