摘要

在婴儿猝死综合征患者中，苯乙醇胺- n -甲基转移酶活性在后歧义核、Kolliker-Fuse核和延髓c2区被发现降低，而多巴胺- β -羟化酶活性仅在c2区被发现降低。这些结果表明，在婴儿猝死综合征的呼吸和心脏中心肾上腺素能神经元活性降低。

[Activities of enzymes synthesizing catecholamines in areas of the brain stem in sudden infant death].

In victims of Sudden Infant Death Syndrome, the activity of phenylethanolamine-N-methyltransferase was found to decrease in the nucleus retroambigu, the Kolliker-Fuse nucleus and the C 2 area of medulla, whereas a decrease in the dopamine-beta-hydroxylase activity was found only in the C 2 area. These results suggest a hypoactivity of adrenergic neurons in respiratory and cardiac centres in the Sudden Infant Death Syndrome.
