圧発汗反射の臨床的検討

Clinical Study on the "Pressure-Sweating-Reflex"

I　まえがき

　己に1934年久野教授は"The Physiology ofHuman Perspiration"の中に中等度の発汗時に側臥位をとると身体の上半部の発汗は増強し，下半部は発汗の抑制がみられることを指摘している。

　その後緒方教授等はこの発汗現象の動機につき各種の実験をなし，圧迫側の欝血と，対側の貧血に依る反射であろうと推論した。

In this paper, so called "pressure-reflex" was studied in many interest clinical cases.

1. Positive pressure-sweating-reflex was fo-und in the cases of patients subjected to tho-racoplasty or artificial pneumothorax and su-fferred from the exsudative pleurisy or other pathologic changes of the pleura.

It may be infered that various kind of chan-ge of the skin, the fascia, the pleura and so on likewise stimulate the receptors of pressure sensation, following to the pressure-reflex.

2. In the case of patients with diseases of the hypothalmohypophyseal system and normal subjects administered with a drug selectively affecting the hypothalamus, negative pressure-sweating-reflex was found.

3. In the case of a patient with extradural-tumor, the pressure-sweating-reflex showed ne-gative reaction.

This patient has complained of disturbances of protopathic sensation in the corresponding area of the skin, but not epicritic sensation. Following recovery of protopathic sensation by removing tumors, positive pressure-sweat-ing-reflex appeared.

From this fact, the pressure-reflex might have a close relation to the pathway conducting Pro-toparhic sensation.
