was diagnosed. Routine neurological examination was done on all and no abnormalities noted. Copies of physical examinations are attached as Tab A, Appendix V. In summary, this was a group of twenty-four healthy young miles who presented no complaints at the time of examination or on questioning and who exhibited no detectible significant abnormalities. C. LABORATORY EXAMINATIONS A red blood cell count, white blood cell count, smear (slide method) for white blood cell differential examination, ‘hemoglobin (Sahli method) were done. Intravenous blood was drawn on six individuals (15 ce each) for examination for radioactivity. These bloods were taken from the antecubital fossa veins directly by separate intravenous needles and allowed to drip directly into a 15 cc vial containing oxylate since we did not have available individual syringes of adequate size. The blood vials were mumbered in accordance with the list attached (see Tab C, Appendix V.) The blood smears were fixed in methyl alcohol for two minutes. They were not stained, but each was marked with a pencil number (no labels available) and placed in order 1-24, in correspondingly numbered slots in a slide box. All blood counts and hemoglobin determination were done in order of taking and recorded (see Tab C, Appendix V) as soon as done. Blood vials were refrigerated at the clinic. Twenty~four hour urine samples were collected on seven people, three from the SATUMA and four from the TAKUYO. 44 (See Tab B, Appendix V, for DOEARCHIVIS EGNTIDEIAL ST es oece
