Figure 1.
Pressor effects (a and b) and heart rate (HR) (c and d) changes induced by angiotensin (Ang) II in nonstressed, stressed, stressed with pretreatment with either captopril (Cap) or pentoxifylline (PTX) rats. The enhanced pressor effect in stressed rats was attenuated by either Cap or PTX pretreatment (n = 6/group; *P < 0.05 vs. baseline; #P < 0.05 vs. nonstressed or stressed rats with Cap or PTX pretreatment).
