Figure 3: Effects of losartan, apocynin, and tempol on the arterial baroreflex sensitivity in STZ-induced diabetic rats.A, reflex ΔMAP and ΔHR in response to different frequencies of ADN stimulation in sham and diabetic rats. B, reflex ΔMAP and ΔHR in response to ADN stimulation (100 Hz) in each group (chemicals were microinjected into the nodoseganglion). Data are mean SE, n=6 rats in each group. *P<0.05 vs. sham rats; #p<0.05 vs. diabetic rats.
