Abstract:
Objective:To investigate the correlation between arterial baroreceptor reflex (ABR) function and target organ dam age (TOD) in spontaneously hypertensive rats (SHR) .Methods:Twenty- four- hour blood pressure (SBP and DBP ) ,blood pressure variability (BPV ) ,heart rate (HR ) and HR variability (HRV ) were m easured in conscious, unrestrained SHR and Wistar- Kyoto (WKY ) rats.ABR function control of heart period (ABR- HP) and blood pressure (ABR- BP) were determined respectively.Hypertensive TOD was evaluated according to the scoring system.Results:SBP, DBP and their BPV were significantly increased in SHR compared with those of WKY rats.No difference of HR was found between the 2 strains,but HRV was significantly decreased in SHR when com pared with WKY rats.ABR- HP and ABR- BP of SHR were significantly decreased compared with those of WKY rats (P
