We therefore tested the blood pressure responses to these two drugs in patients with schizophrenia, endogenous depression, and mixed neuroses.

Method and Subjects  This method has been previously reported.5 All subjects were given epinephrine and methacholine (Mecholyl) on separate days.The 21 schizophrenics ranged in age from 16 to 49 years, with a mean of 35.1 years. The 22 patients with endogenous depression ranged in age from 26 to 56 years, with a mean of 47.9 years. The 25 patients
