PAN occurs when the specific gravity of the membrane space of the semicircular canals in the ear differs from the specific gravity of the fluid in the canals because of the presence of alcohol. == PAN I == When a person consumes alcohol, the alcohol is carried by the bloodstream and diffused into the water compartments of the body. Normally, the specific gravity of a canal membrane is the same as the specific gravity of the surrounding fluid. Because of this, even though the Earth's gravity is a constant force of acceleration, the semicircular canals do not respond to it. Alcohol has a lighter specific gravity than water. When alcohol enters the canal membrane via capillaries, the specific gravity of the membrane is lower than that of the surrounding fluid. The alcohol does diffuse from the membrane to the fluid, but it does so very slowly. While the specific gravity of the membrane is lower than the specific gravity of the extracellular fluid, the hair cells on the membrane become responsive to the Earth's gravity. This is the condition of PAN I. PAN I is characterized by a nystagmus to the right when the right side of the head is down. It is typically present during a rising and peak Blood Alcohol Concentration (BAC), and becomes noticeable at around 400 mg/dL (.40% BAC). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Positional alcohol nystagmus」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
