Changes in heart rate (HR). (a) Time course of HR before, during, and after stress loading. HR values from all tested rats were averaged and normalized to baseline (HR recorded for 2.5 min before stress loading) and set as 100%. Stress-induced HR increase was suppressed by prior administration of a representative high dose of arundic acid (200 mg/kg), although the effect of arundic acid on HR responses to stress was not dose-dependent. (b) Average change in HR (ΔHR) during air-jet stress (left) and post-stress (right) periods compared to the pre-stress resting state. There was no significant difference compared to the control in any period. Data are presented as means ± SE, n = 13 per group.
