Enzymatic diagnosis of infarction.

WE ARE IMPRESSED with the evident sincerity of the effort of the Food and Drug Administration (FDA) to establish genuine two-way communication with practicing physicians. Commissioner Donald Kennedy's article elsewhere in this issue bears witness to this. And the fact that high officials of the FDA will be present and respond to physicians' questions and comments at a "Tell It to the FDA" session at the Annual Meeting of the California Medical Association on March 18, 1978 is further evidence of this sincerity. In recent years the FDA has become more aggressive in carrying out its legal mandate and indeed its hand has repeatedly been strengthened by the Congress. But all has not been well with the agency. There have been internal difficulties-inadequate staffing and mounds of paperworkas well as external criticism. For reasons, some but not all of which
