the mean ( +/- sem ) value for urinary excretion of dopamine ( 52.4 +/- 8.8 micrograms/day ) in diabetic patients with nephropathy ( group c , n = 12 ) was significantly lower ( p less than 0.01 ) than in the normal subjects ( group a , 179.7 +/- 15.5 micrograms/day ) and in diabetic patients without nephropathy ( group b , n = 9 , 131.5 +/- 16.5 micrograms/day ) .
