Research Abstract

A new method for measuring method of stress indicator, which is measurable in a slightamount of blood andshort time, had been developed at the beginning. Mild restrain stress induded a alight decrease of leucocyte number and shortening fibrin clotting time , but variability was quite-variable and whole volume of blood was necessary in mice, which is suitable for behavioral analysis. Spontaneous chewing behavior was induced during mild restrain stress and enhanced learning effect in the morris water maze test.
