to evaluate the pathophysiologic importance of renal nerves in regulating the renal vasomotor tone , we measured several parameters of renal cortical microcirculation before and after acute renal denervation ( dnx ) in the following three groups of anesthetized munich-wistar rats : ( group 1 ) congestive heart failure after surgically induced myocardial infarction ( n = 10 ) , ( group 2 ) acute extracellular fluid volume depletion after deprivation of drinking water for 48 h ( n = 8 ) , and ( group 3 ) sham or nontreated controls ( n = 6 ) .
