Emax (%) 26±1.8 18±2.0& 27±2.0 11±2.7*#

Data are mean±S.E.M. and “n” values refer to the number of animals from which the data were obtained.

&

Indicates significantly different from the S50 or Emax in control sham MA (MV) (P<0.05).

*

Indicates significantly different from the S50 or Emax in control DOCA-saltMA (MV) (P<0.05).

#

Indicates significantly different from the S50 or Emax in prazosin treated sham MA (P<0.05). Data analyzed using analysis of variance and Student Newman Keuls post hoc test.
