Five healthy adult post-menopausal female volunteers were each given a single dose of 1600 mg of WR-6798-35S containing 100 microcuries of 35S together with a single standard chloroquineprimaquine tablet, with urine, stool, plasma and red blood cell collections made both prior to and over the period of the ensuing 13 days. One subject developed clinical cyanosis with symptoms compatible with anemia and was found to have significant methemeglobinemia 32 of her total hemoglobin was in this form. No treatment was given and she recovered spontaneously over the course of the next several days. No reduction in G-6PD, 6 phosphogluconic dehydrogenase, glutathione reductase nor methemoglobin reductase values could be demonstrated. The results of the radioactivity determinations done elsewhere were not available at the time of the preparation of this report. Author
