trypsin I have also noticed a disagreeable complication, which consists in this, that often the digestive power of the trypsin passed over also to sound tissue, and a disagreeable destruction of this came to pass. Recently Sticker and Falk have improved the trypsin-therapy in that they have united the action of trypsin to charcoal, by which means, after a single injection, this action persists much longer, since this carbenzyme is not so quickly used up as ordinary trypsin.”
Regarding the foregoing, only a few words need be added. It will be noted that Blumenthal also confirms the “ liquefying” action of trypsin on cancer. This has now happened in London, Berlin, New York, and elsewhere. The researchers of the Imperial Cancer Research Fund denied some years ago that trypsin had any action at all upon cancer-cells. Looked at scientifically, either trypsin acts upon living cancer-cells, and
scientific paper. Moreover, as Professor Blumenthal is quite aware, the results of his own experiments with “trypsin “ are in direct contradiction with the verdict pronounced, without the production of any evidences, by officials of this cancer research. It reminds one of the reception accorded to von Siebold’s discovery of two sorts of spermatozoa in a fresh-water dioecious snail, Paludina vivipara, in 1836. Within an easy walk of Würzburg, this snail is readily found in great numbers, and the first time that these two sorts of sperms were seen by me was in 1882, in living material obtained not far from Würzburg. None the less, when von Sicbold published his find, the Professor of Anatomy in the University of Würzburg, the celebrated anatomist and embryologist, Albert von Kölliker, interposed the weight of his authority, and, without taking the trouble to examine the facts for himself in the animal concerned, disposed of von Siebold’s finds . . . simply by denying the correctness of his observations. Since that time an extensive literature has sprung up concerning twofold sperms in Paludina and many other animals, including man, and the well-known cytologist, F. Meves, has published a minute account of the development and histology of these two sperms of this snail, the wormlike and the hairlike forms.
