Medical Plans Discussed by APHA Opposition to compulsory national health insurance and encouragement and expansion of voluntary health insurance programs was the stand taken b y the American Pharmaceutical Association as it met in Jacksonville, Fla., t h e week of April 2 4 for its ninety-sixth annual con vention. T h e week was also observed throughout the nation as National Pharmacy Week. A much more responsible position for the pharmacist as a member of the health team was the goal of a six-year curriculum proposed b y the associa tion's committee on curriculum for pharmacists. J. Lester Hyman, of the West Virginia College of Pharmacy and president of the American Association of Colleges of Pharmacy, in commenting oa the proposal stated that if the pharm acist were to be a truly professional man and understand t h e scientific basis of his work, and in addition be compet ent t o advise physicians about drugs, a six-year curriculum must be estab lished. More than 60 papers were presented before the scientific section, highlight of which was a symposium on blood and blood products under the leadership of Edwin Cohn of Harvard University Medical School. Awards made during the meeting in cluded the presentation of the 1948 Iodine Educational Bureau Research Award to William T . Salter of Yale University for his work on the study of iodine in nutrition and metabolism. The Ebert Prize for outstanding re
