Abstract　： [Abstract] It has been proposed that suppression of stress-related emotional responses leads to the simultaneous activation of both sympathetic and parasympathetic divisions of the autonomic nervous system (ANS) and that the expression of these emotional states has a protective effect against ulcerogenesis. In the present study, we investigated whether stress-induced bruxism activity (SBA) has a physiological effect of on the stress-induced changes of the stomach as well as blood leukocytes, cortisol, and adrenaline. This study demonstrated that SBA attenuated stress-induced ulcerogenesis. SBA also attenuated increases of adrenal ine, cortisol, and neutrophils in the blood. In conclusion, expression of aggression through SBA during stress exposure attenuates both stress-induced ANS response and ulcerogenesis.
