Figure 9
Effects of endothelial nitric oxide synthase enzyme blockage on changes in (a) MAP, (b) SBP, (c) DBP, and (d) HR by various treatments in WKY rats (). L-NAME: N-ω-nitro-l arginine methyl ester, 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. ***.
