Abstract

Vulnerability to sudden death was produced in laboratory rats by manipulating their developmental history. Rats who were reared in isolation died suddenly when placed in a stressful swimming situation. Handling of these singly-housed rats from 25 to 100 days of age potentiated the phenomenon. However, animals who were group housed did not die even when they had been previously handled.

摘要

通过操纵实验大鼠的发育史，使其产生了猝死易感性。单独饲养的大鼠在置于应激性游泳环境中时会突然死亡。在25至100日龄期间对这些单独饲养的大鼠进行处理会增强这种现象。然而，群居饲养的动物即使之前接受过处理也不会死亡。
