Outline of Final Research Achievements |
The intermittent hypoxic exposure of the awake (under conscious) experimental animals has been analyzed as experimental animal models of obstructive sleep apnea syndrome. However rapid respiratory failure due to tongue root depression is occurred in actual cases of obstructive sleep apnea syndrome. Therefore, it is expected that it is different condition from obstructive sleep apnea syndrome. In this study, it became clear that intermittent obstructive respiratory failure and intermittent hypoxic exposure under anesthesia (unconsciousness) are different pathologies. In addition, we clarified that the occlusion time, not the number of occlusions, is related to the deterioration of the pathological condition.

Academic Significance and Societal Importance of the Research Achievements |
閉塞型睡眠時無呼吸症候群は、舌根沈下などにより睡眠時の呼吸が停止することを繰り返すことで、良好な睡眠の妨げ、日中傾眠を誘発する。その結果、交通事故・災害事故・社会生活や家族問題を引き起こすなど、社会的問題になっている。本研究にて、新たに、閉塞型睡眠時無呼吸症候群の臨床病態を反映した実験動物モデルを確立したことにより、今後、診断、治療への応用研究が加速すると予想される。
