erythrocyte enzyme activity in acute intermittent porphyria mice (7.3 pM uroporphyrin/mg hemoglobin) does not improve with bone marrow graft from porphyria mice (5.2 pM uroporphyrin/mg hemoglobin), increases to 12.4 pM uroporphyrin/mg hemoglobin in mice grafted with bone marrow from wild type, wild type has an activity of 16.9 pM uroporphyrin/mg hemoglobin, erythrocyte enzyme deficiency is not associated with acute porphyria, 37°C, phosphate buffered saline |
