The ent-15𝛼-Acetoxykaur-16-en-19-oic Acid Relaxes Rat Artery Mesenteric Superior via Endothelium-Dependent and Endothelium-Independent Mechanisms

Table 2

Effect of TEA in the relaxant effect of KA-acetoxy.

Phenylephrine 10 (𝜇M)	𝐸max	pD2
(condition)	(%) relaxation	(value)
Endothelium intact	92.8 ± 3.7	6.0 ± 0.3
Endothelium denuded	95.2 ± 2.8	4.6 ± 0.2
Endothelium intact + TEA (5 mM)	90.7 ± 3.1^a	5.4 ± 0.4^a
Endothelium denuded + TEA (5 mM)	100 ± 0^b	4.4 ± 0.2^b

Values are expressed as means ± SEM of six experiments. The data were analysed by one-way Anova followed by the Bonferroni post-test.
^aCompared to endothelium intact.
^bCompared to endothelium denuded.
