OHMI, T., MUE, S., TAKAHASHI,M., SHIBAHARA,S., YAMAUCHI,K., TAMURA, G., FUJIMOTO, S., CHEN, H.C. and TAKISHIMA,T. Effects of Adrenergic Agonists and Antagonists on Immediate Cutaneous Reactions in Bronchial Asthma. Tohoku J. exp. Med., 1979, 127 (2), 197-198 Asthmatic patients who showed an allergic skin reaction to house-dust antigen (HD) were injected intradermally with a mixture of HD and a various dose of isoproterenol (Isopr) or propranolol (Propr). In some cases Isopr clearly suppressed the formation of the wheal, but in some others Isopr did not much affect the allergic skin reaction. Also Propr increased markedly the skin reaction of some patients, or had little effect on it. The sensitivity of the skin of asthmatic patients to these drugs was closely correlated with the general response of the patients to adrenaline, such as changes in heart rate, diastolic blood pressure, blood glucose level, and blood triglyceride level. adrenergic drugs; skin and systemic response; asthma Imbalance of the autonomic nervous system has been cited as one of the etiological factors in bronchial asthma (Cookson and Reed 1963; Shereff et a]. 1973). The present study was undertaken to see whether such imbalance was corroborated in the skin of asthmatic patients by observing the effects of adrenergic agonists and antagonists on antigen-induced

effect of Propr was doubtful in the remaining 18 patients. The effect of the adrenergic drugs on the allergic skin reactions was so much variable in asthmatic patients that we classified the skin sensitivities to adrenergic drugs into 4 types as follows: I-P (the effects of both Isopr and Propr were positive); I-p (Isopr suppressed the skin reaction but Propr gave a negative effect); i-P (Isopr gave a negative effect on the wheal but Propr increased the skin reaction); i-p (neither Isopr nor Propr was effective).
