Alterations in vasomotor systems and mechanics of resistance-sized mesenteric arteries from SHR and WKY male rats following in vivo testosterone manipulation

Table 4 Passive mechanical parameters from SHR and WKY treatment groups

Treatment	Strain	CONT	CAST	CAST + T
Wall stress (dyn/cm² × 10³)	SHR	*3.6 ± 0.3 (n = 9)	*4.3 ± 0.4 (n = 12)	*3.9 ± 0.5 (n = 10)
	WKY	6.9 ± 1.0 (n = 8)	6.2 ± 0.8 (n = 8)	5.9 ± 0.7 (n = 12)

CAST, castrate; CAST + T, castrate plus testosterone; CONT, control; NE, norepinephrine; SHR: spontaneously hypertensive rat; T: testosterone; WKY: Wistar Kyoto. Data are means ± SEM. All data were collected at 60 mmHg.*= P < 0.05 SHR CONT vs WKY CONT; * = P < 0.05 SHR CAST vs WKY CAST;*= P < 0.05 SHR CAST + T vs WKY CAST + T.
