摘要

以出生後一至十七天未斷奶之小白鼠作爲實驗動物，將其放入灌以純氧之加壓室中，以每分鐘10 psig之壓力逐漸增加該室內之壓力，藉此觀察其有否呈現高氧壓痙攣（簡稱氧痙攣）。實驗之結果，知出生後一至十二天之小白鼠均不能引起氧痙攣；出生後十三天、十四天、十五天及十六天之小白鼠呈現氧痙攣之百分率順序爲10％、30％、80％及100％。由此顯示出生後一至十二天之小白鼠，其氧痙攣機構尙未成熟，故不能引起氧痙攣。出生後十二至十六天，該機構逐漸成熟，故逐漸增加呈現氧痙攣之百分率。氧壓增高之際，尙可引起肺損傷。小白鼠呈現肺損傷之百分率，亦隨出生後日數之增加而逐漸增高。有些小白鼠雖呈現肺損傷，但未引起氧痙攣，故兩者似不相關。

Chen,C.F.and H.S.Fang:High oxygen pressure-inducedconvulsions in suckling mice.Chinese J.Physiol.,22(1):1-5,1975,—Two hundred suckling mice from 20 litters were used fordetermining their functional development of the hyperoxic convulsionmechanism.It was found that 1 to 12-day-old mice did not developconvulsion when they were subjected to oxygen under high pressure.The hyperoxic convulsion was observed in 1 of 10 13-day-old(10%),3 of 10 14-day-old(30%),16 of 20 15-day-old(80%)and all of16-day-old mice(100%).This finding indicates that the hyperoxicconvulsion mechanism of the young mice takes 13-16 days for functionalmaturation.Besides,it was shown that hyperoxia couldcause pulmonary damage,the incidence of which also increased withage of suckling mice.
