Contractile response to KCl and to phenylephrine of the aortic rings with (+) or without (−) perivascular adipose tissue (PVAT) or endothelium (E) from male Wistar rats (300–350 g)

	KCl	Phenylephrine
	(60 mM; g)	Emax (% of KCl)	EC50 (μM)	n
PVAT+E+	1.8±0.1	101±3a	0.28±0.05a	7
PVAT-E+	1.7±0.07	124±2b,a	0.11±0.01b,c	7
PVAT+E-	1.9±0.19	132±2b,a	0.14±0.03	6
PVAT-E-	1.5±0.05	161±3b	0.06±0.01b	6

No statistical difference was found between PVAT+ E− and PVAT− E+ rings (P>0.05).

^aP<0.01 versus PVAT− E− rings.

^bP<0.01 versus PVAT+ E+ rings.

^cP<0.05 versus PVAT− E− rings.
