To elucidate the Ca2+ release mechanisms in the rabbit coronary artery, arterial preparations were permeabilized with beta-escin and changes in tension were measured under varying experimental conditions. Additionally, we investigated...
It was hypothesized that NaF induces calcium sensitization in Ca2+-controlled solution in permeabilized rat mesenteric arteries. Rat mesenteric arteries were permeabilized with beta-escin and subjected to tension measurement. NaF potentiated...
BACKGROUND: Extracellular and intracellular pH (pHo and pHi), which can be changed in various pathological conditions such as hypoxia, affects vascular contractility. To elucidate the mechanism to alter vascular contractility...
In the present study, it was aimed to further identify the
intracellular action mechanism of cromakalim and levcromakaliin in the
porcine coronary artery. In intact porcine coronary arterial strips
loaded with fura-2/AM, acetylcholine...
Many gastrointestinal muscles show electrical oscillation, so-called "slow wave", originated from interstitial cells of Cajal (ICCs). Thus, a technique to freshly isolate the cells is indispensable to explore the electrophysiological...
