Variable	Angiotensinogen (ng/mL)	Angiotensin-II (pg/mL)	Renin (pg/mL)
NG	18.3±1.7a	5.8±1.5a	153.6±23.7a
NCG	28.1±2.3c	13.4±1.0c	204.8±15.5d
PCG	21.6±1.9ab	8.4±1.9b	175.2±12.0b
LTG	24.6±3.8bc	10.0±0.7b	194.7±18.0cd
MTG	23.9±3.3bc	9.1±1.7b	180.4±11.5bc
HTG	21.7±1.7ab	8.7±1.7b	177.5±11.4b

All values are the mean±SD (n=8).
In the same column are significantly different (p<0.05).
NG, normal group (WKY) with distilled water; NCG, negative control group (SHR) with distilled water; PCG, positive control group (SHR) with Enalapril; LTG, low treatment group (SHR); MTG, medium treatment group (SHR); HTG, high treatment group (SHR); WKY, Wistar-Kyoto rats; SHR, spontaneously hypertensive rats.
