The effect of HIH treatment on acute hypoxia-induced depressor and sympathoexciatory effect in anesthetized rats.

<p>A: Original recordings showing the responses of ABP and RSNA to acute hypoxia (O₂∶10%; N₂∶90% for 2 min) in one control and one HIH rat. B, C, and D: Summary data showing the acute hypoxia-induced alteration of ABP (B), RSNA (C) and HR (D) in control and HIH-treated rats. The summary measurements were derived from the peak responses of ABP, HR, and RSNA, respectively. AH, acute hypoxia; ABP: artery blood pressure; HR: heart rate; RSNA: renal sympathetic nerve activity. All data expressed as mean ± SEM, n = 7 for each group, *P<0.05 v.s. control group.
