[Influence of recent modification of behavioral relationships of male and female OF1 mice on resistance to nitrogen or carbon monoxide hypoxia].

A decrease of resistance to hypoxia is obtained in OF1 mice, 24 hours after an hyperactivity resulting from a grouping by 13 of male or female mice previously isolated. Besides, this decrease is statistically significant in an acute nitrogen hypoxia but not in an acute carbon monoxide poisoning. In both hypoxias, in mice of same age the males are less resistant than females.
