Abstract

³H-imipramine binding was studied in the blood platelets of 80 normal controls and 50 depressed (psychotic and nonpsychotic) patients. Protein concentration in the incubation mixture, and K_d and B_max values were correlated in normal controls and depressed patients. A small but significant correlation between protein in the incubation mixture and B_max was observed in normal controls and depressed patients. There was also a significant correlation between protein and K_d of imipramine binding in the blood platelets of unipolar psychotic depressed patients. However, analysis of covariance to remove the effect of protein on K_d and B_max did not change the basic finding of decreased B_max in the blood platelets of psychotic depressed patients.
