nicotine or acetylcholine ( ach ) significantly increased the proportion of norepinephrine in the effluent whereas muscarine did not alter the relative proportions of epinephrine and norepinephrine . d-tubocurarine and hexamethonium ( c6 ) inhibited the response to nicotine completely but scarcely affected the response to ach and significantly potentiated the response to muscarine .
