Figure 5
Effects of autonomic ganglion receptors’ blockages on changes in (a) MAP, (b) SBP, (c) DBP, and (d) heart rate by various treatments in WKY rats (). Hexa: 10 mg/kg hexamethonium bromide, ΔMAP/SBP/DBP/HR: changes of MAP/SBP/DBP/HR from baseline (expressed as mean percentage ± SD), AESP: aqueous extract of S. polyanthum leaves, met-AESP: residual methanolic extract of S. polyanthum leaves, WKY: Wistar-Kyoto rats, SHR: spontaneously hypertensive rats. * and **.
