THE INTERLUDE OF CANCER 139
toms very soon arise, all of which recall the vomiting of pregnancy and eclampsia. Trypsin alone is a very deadly remedy for cancer, the reason being that in killing the cancer albumins this enzyme does not split them up to harmless simple products. What the products of the action of trypsin alone are it is impossible to say, for they may quite conceivably vary with the amount of the injection, its strength, and with the size of the tumour. Anyway, some of them are rank poisons to the organism, and they lead to nausea, vomiting, pain in the back, drowsiness, high arterial tension, albuminuria, oedema, etc., and even to convulsions, lasting several hours. The cause of such symptoms and of the eclampsia of pregnancy did not long puzzle the embryologist, who perceived that it was the absence of the complementary ferment, amylopsin, which induced them. Nature had committed a grave error in omitting amylopsin from foeta1 blood, and in relying solely on trypsin. In normal gestation, if anything went wrong with the maternal pancreas gland, and if the maternal supply of amylopsin became diminished or ceased, then serious symptoms were bound to follow. To my knowledge, at the moment of writing, injections of amylopsin have not yet been given in any case of eclampsia, but they have, whenever used in cases of cancer, removed all the bad symptoms named.
The preparations employed in the enzyme treatment of cancer should be like those first used in America— the Fairchild preparations; that is to say, they must be potent extracts, scientifically prepared from the fresh gland direct. The trypsin injection must be especially rich in trypsin. The injection of amylopsin must have great amylolytic potency, and it is also to be used at all times to meet and remove all bad symptoms, and in the later periods of treatment, when all the cancer albumin
