3 when platelet homogenates from 20 individual subjects were tested , there were significant correlations between pst activities measured with dopamine and those measured with md , mda and mna ( r = 0.54 , 0.98 and 0.93 , p less than 0.02 , less than 0.001 , and less than 0.001 , respectively ) , but not between activities measured with low concentrations of phenol and those measured with md , mda and mna ( r = 0.021 , 0.045 and 0.046 , respectively ) .
