Effect of thermal irritation on gastric function Friedrich (Zeit. f. d. ges. physik. Therapie, 1924, Bd. 28)

In practice, very often cold and heat are used for diseases of the stomach, and until now it was unclear what the effect of thermal irritation is based on here; apparently, in addition to the known effect of contrast temperatures on the vessels and body temperature, there is also an indirect effect of thermal stimuli on the body through the sympathetic system. Recently, Weitzn Sterkel observed that when X-ray of the stomach the latter gives a different picture if the X-ray occurs in a cold room than when it is done at ordinary room temperature, namely, in a cold room the stomach is hypertonic, which Friedrich (Zeit.fd ges. physik. Therapie, 1924, Bd. 28) considers not as a result of the direct action of cold, but as a reflex phenomenon, due to irritation of the parasympathetic nerve plexus.
