（20）眼における非特異反応の起原について

Non-specific occular reaction and its origin.

　私共はさきに，作用物質の反復注射や電撃シヨツク，足部電気刺戟，施灸，湿熱などの刺戟によつて，眼底出血及び充血と角膜混濁を主徴とする非特異反応が，ウサギの眼におこることを証明した^1）2）。そこで私共はまず，この反応を直接ひきおこすものは何であるかを追求して2つの因子をみいだした。厳密な証明は別著にゆずることとし，ここでは現在までにえられた成績をとおして，自由な立場でこの反応の起原についてのべてみたいとおもう。

Experimentally in rabbits it has been shown that a state of fundus hemorrhage, hyperemia and corneal opacity may be established when the animals are exposed to various external stimuli such as repeated administration of activating substances by injections, electric shocks, moxibustion or extreme heat with high humidity. The authors believe that there are two basic factors that are contributing to these changes.

The first of these is the action of a crystaline substance that is obtainable as extracts from the liver, kidneys and lungs of the animal that has been exposed to external stimuli to the point where a non-specific eye reaction has been established. This substance when injected into the vitreous humor of a normal will cause a retinal hemorrhage.
