TREATMENT OF HUMAN HOOK WORM INFECTION WITH CARBON TETRACHLORIDE

Cutrve lype 5 (Fig. 5). This is the "climbing " curve or curve of tardive hyperacidity (Hawk), due presumably to deficient relaxation or spasm of the pylorus of a non-continuous type; this picture has also be'en seen ji what can only be called idiopathic hyperchlorhydria, sinice no s,asm or cause for spasmcould be recognized. A'great mEjority of these curves were, in my own series, associated withl either mnall pyloric ulcers (leading presumably to spasm), or with subpyloric conditions, such as appendicitis, whereperhaps pyloric spasm was a reflex event similar to that observed in the experimental intestinal injuries.-of Ca'nnon and Murphy. Removal of the subpyloric condition, which wvas postulated as -a cause of the "reflex hyperchlorhydria " expressed by this type of curve, has, in'my own series, been followed by an alteration approximating to Type 1. Curves of this type were obtained in six cases which came to operatio,' anid which exhibited lesions varying from a small pyloric ulcer to an inflamed appendix.
