3. The presence of secretin or prosecretin cannot be demonstrated in the commercial preparations “Secretogen,” “Elixir Secretogen” and “Duodenin” even when the therapeutic dose of the preparations is given intravenously. In the case of “Secretogen,” intravenous injection of 100 times the therapeutic dose reveals occasionally an insignificant trace of secretin. DISCUSSION OF RESULTS It is, of course, objectionable that preparations containing no secretin should be advertised to the medical profession as containing this substance. The more important blunder, however, consists in the attempt to offer such preparations for oral administration, because even chemically pure secretin would be equally ineffective when taken by mouth. There is as yet no reliable evidence that lack of secretin is a primary or important factor in any disease. Even should this be established, secretin therapy, to be effective, must be intravenous. Secretin has not yet been prepared in sufficiently pure state to render possible intravenous injection in man without injurious effects. And even when this has been attained, the very fleeting action of secretin will in all probability render secretin therapy as futile in all the diseases in which it is theoretically indicated as epinephrin therapy is in Addison’s disease. But there remains the alleged favorable effect from secretin therapy by mouth in various diseases in man. It is, perhaps, impertinent for laboratory men to comment on these clinical results. The ordinary “testimonials” need not be considered, but we should like to ask the serious worker who thinks he has actually obtained good results from secretin therapy how certain he is of the causal relation between the giving of secretin or alleged secretin and the abatement of the disease. When a therapeutic measure not only lacks a positive basis in physiology and pathology but runs contrary to all the well-established experimental facts in these fundamental medical sciences, is it too much to ask that positive clinical findings be subjected to more than usual critical analysis before acceptance? “_Clinical tests_,” it is said, “covering a period of several years have proved that neither the condition in the stomach during digestion nor those in the intestine prevent the secretin from entering intact into the circulation.” When we meet claims such as this, should we not scrutinize the “tests” as well as the men who make them? We are indebted to Dr. J. H. Moorehead for assistance in part of the surgical work.--(_From The Journal A. M. A., Jan. 15, 1916._) ARTICLES REFUSED RECOGNITION Report of the Council on Pharmacy and Chemistry Below appear abstracts of the Council’s action on articles refused recognition which were not deemed of sufficient importance to require lengthy reports: Radio-Rem
