“Inasmuch as this improvement could not have been due to the contained secretin it must have been due to some other principle contained in the extract. Our experience and that of the physicians who have used Secretogen establish the fact that Moore, Edie and Abram made no mistake when they came to the conclusion that what they termed a secretin-bearing extract stimulates the functional activity of the duodenum and improves the digestion.
“When Professor Carlson was investigating Secretogen he must have realized that he was dealing essentially with an extract of the duodenal mucosa. It is, therefore, all the more surprising, considering his extensive researches into the literature, that he should have ignored the testimony of some of his own authorities, particularly Hallion, as to the value of extracts of the duodenal mucosa in duodenal insufficiencies. The meticulous carefulness with which this evidence was avoided is hardly worthy of the best traditions of physiology, a science which has truth for its first and last aim.
“Hallion in his ‘La Pratique de l’Opothérapie’ says that the ‘aims of duodenal opotherapy are: 1, To supply deficient duodenal juice. 2, Above all to stimulate and to relieve this organ—notably to aid the production of secretin[106]—and so profit by the stimulating action which duodenal extract exercises on the duodenal mucosa which action we, Enriquez and myself, believe and have experimentally proved, conforms to the general principles of opotherapy. 3, By means of the production of secretin, to reinforce the biliary, pancreatic and intestinal secretions. 4, To stimulate intestinal peristalsis.
“ ‘Principal indications: Intestinal dyspepsias, intestinal autointoxications, certain forms of constipation and duodenal insufficiency.’
“At the International Congress of Medicine, Madrid, 1903, Hallion said that he felt justified in stating that duodenal opotherapy correctly carried out must be classed under the very best methods of treating dyspepsia.[106] The results had been satisfactory and, in many cases, remarkable. It had been nil in a few cases but it had never been harmful in any degree. He pointed out that Marfan was the first to employ this substance clinically. Marfan had had particularly excellent results in children of 15 months to 4 years suffering with marked malnutrition, anorexia and constipation. Marfan prescribed the duodenal extract given in milk.[106] Hallion further remarks that, as he is not a practitioner, he had had only one opportunity to test duodenal opotherapy clinically. The case was that of a man of 26 years with obstinate intestinal dyspepsia and severe constipation which had persisted from childhood. This patient had been treated by enemas, laxatives, diet, etc. Treatment with duodenal extract resulted in a complete cure.[106] Hallion points out that the most satisfactory aspect of duodenal opotherapy is the permanent effect produced,[106] which bears out his statement that these extracts have the power to aid in the restoration of function and structure of an organ.
“This has been so well established that the principle is now embodied in a law which is frequently referred to as ‘Hallion’s Law’: ‘Extracts of an organ exert on the same organ an exciting influence which lasts for a longer or shorter time. When the organ is insufficient it is conceivable that this influence augments its action and, when it is injured, that it favors its restoration.’
“In ‘La Pratique de l’Opothérapie’ Hallion points out that ‘the opotherapeutic product which corresponds to the affected organ represents in some way the stimulating and elective food for that organ, and if we supply the organ with a food which is more complete than it necessarily needs, the affected organ can exercise its elective action and take up only those substances of which it is in need.’
“Hallion’s observations on this point are beautifully borne out by the classic work of J. W. Draper, as reported in The Journal of the American Medical Association, Sept. 26, 1914. This report gives results in both laboratory and clinical experiments.
“In order to show that fed jejunal and ileac epithelium exercise some special detoxicating power, not yet understood but definitely recognizable, Draper fed a control series of dogs with intestinal obstruction, experimentally produced, on emulsified cells of liver, spleen, pancreas and muscle tissue. These animals lived a few hours longer than not-fed controls, but Draper says that it is evident that these cells had either no detoxicating action, or a very feeble one compared with intestinal epithelium. He used jejunal and ileac epithelium clinically in two instances: 1st, In a female dog which had had ‘chronic stomach trouble’ for six months. When Draper saw her she had had complete intestinal obstruction for five days, with symptoms of tachycardia, extreme nervousness and great weakness in the hind legs. Draper removed a pebble from her intestine but her condition was still grave.
“She was immediately put on small-intestine epithelium derived from two dogs of different breed. Draper says that from a long experience with duodenally obstructed dogs, he should not have expected her to recover, but the symptoms gradually subsided and she lived. The second instance in which he used the epithelium therapeutically was in the case of a man who suffered from an annular cancer of the intestine with definite symptoms of obstruction. After the operation, and realizing that the patient was in a desperate condition, he fed him an emulsion of intestinal epithelium from a dog. The pulse improved and the patient lived.
