Six healthy students as subjects, saline, hydroxyzine (500μg/kg body weight), mepazine (the same), and acetylcholine (400μg/kg) had no effect on the capillary resistance threshold, but atropine (10μg/kg) and pilocarpine (100μg/kg) showed acute rise and fall in the threshold, respectively. When adrenaline (5μg/kg) and noradrenaline (5μg/kg) were combined with hydroxyzine or mepazine, the initial rise was lost with adrenaline, but not with noradrenaline. On the basis of these findings, the primary role of the autonomic nervous system in modifying the capillary resistance was suggested.
