The operation of injecting blood taken from one person into the veins of another. Trichina Spiralis. A minute species of parasite, or worm, which infests the flesh of the hog: may be introduced into the human system by eating pork not thoroughly cooked. Name given to two projections on the upper extremities of the femur, which give attachment to the rotator muscles of the thigh. Trypsin.
The history of science was making fast, and I was interested in a thousand subjects. Why, there was my theory of the hydrolysis of casein by trypsin, which Professor Walters had been carrying out in his laboratory. Also, Professor Schleimer had similarly been collaborating with me in the detection of phytosterol in mixtures of animal and vegetable fats.
This is accomplished by the trypsin, which is similar to, but more active than, the pepsin. It digests fat. In this work the active agent is the steapsin. The necessity of a milk-curding enzyme, somewhat similar to the rennin of the gastric juice, is not understood. *Digestion of Fat.*—Several theories have been proposed at different times regarding the digestion and absorption of fat.
Nor is this all, for it also acts powerfully upon the proteids not acted upon in the stomach, and changes them into peptones that do not differ materially from those resulting from gastric digestion. The remarkable power which the pancreatic juice possesses of acting on all the food-stuffs appears to be due mainly to the presence of a specific element or ferment, known as trypsin. Experiment 60.
Babbit and Battle report an ingenious method of removing a piece of meat occluding the esophagus the application of trypsin.
For the disease itself, after it has once started, there is, like treason in the body-politic, but one remedy capital punishment. Parleying with the rebels is worse than useless. Pastes, caustics, X-rays, trypsin, radium, all are fatally defective, because they suppress a symptom only and leave the cause untouched.
So far will this resemblance go that a secondary cancer of the pancreas found in the lung will yield on analysis large amounts of trypsin, the digestive ferment of the pancreas. Similarly a cancer of the rectum, invading the liver, will there pile up in the midst of the liver-tissue abortive attempts at building up glands of intestinal mucous membrane.
