The present experiments were carried out to elucidate whether pharmacological nature of
caffeine (1 mM)-induced endothelium-dependent contraction (EDC) is different from that of …

We examined whether or not caffeine caused an endothelium-dependent contraction (EDC)
in canine mesenteric artery and whether the endothelium-dependent contracting factors …

Caffeine (10 (-4)-10 (-3) M) induced concentration-dependent relaxations of phenylephrine-
precontracted rat aortic rings with endothelium. Endothelial denudation significantly, but only …

The purpose of this study was to investigate the effect of atropine on peripheral vasodilation
and the mechanisms involved. The isometric tension of rat mesenteric artery rings was …

Aims Caffeine is a methylxanthine with multiple actions in vascular smooth muscle cells
(VSMCs), including the increase in the intracellular Ca 2+(i Ca 2+) concentration by the …

Effects of tetrandrine (TET), a bisbenzylisoquinoline alkaloid, on the contractile responses of
perfused rat mesenteric arteries to phenylephrine (PE) and caffeine were investigated. TET …

This study was aimed to investigate the vascular activity of caffeic acid phenethylester
(CAPE), one of the major components of honeybee propolis. Experiments were performed …

Characteristics of caffeine-induced contraction were compared with those of high K+-and
norepinephrine-induced contractions in order to evaluate the participation of the Ca++ …

1 Single cell photometry and whole‐cell patch clamp recording were used to study caffeine‐
induced intracellular Ca2+ signals and membrane currents, respectively, in endothelial cells …

Abstract Caffeine (1–60 mM) induced concentration-dependent, endothelium-independent
phasic contractile responses in isolated rabbit renal artery ring preparations. For …
