The present study was designed to prove whether the activation of the sarcolemmal Na+/K+-
ATPase in the rabbit aorta could explain the decreased contraction caused in this tissue by …

We investigated effects of three kinds of putative protein kinase C (PKC) inhibitors,
calphostin C, 1-(5-isoquinolinesulfonyl)-2-methylpiperazine (H-7), and stauro-sporine, on …

The present study examined the effects of various agents on high calcium–induced
relaxation of the rabbit thoracic aorta precontracted by phenylephrine (0.1 μM) or KCl (30 …

In the rat and guinea-pig aorta, we observed that the contraction to hypertonically-added K+,
unlike the isotonic K (+)-induced contraction, was only partially sensitive to nicardipine (0.1 …

To evaluate the relationship between the vasocontractile effect of thiopental and the extra
and intracellular sources of Ca2+, we analyzed both the contractile effect of the barbiturate …

The ionophore A23187 initiated contractions in both dog coronary artery and rabbit aortic
strips in a dose-dependent manner whereas X537A contracted rabbit aortic strips and …

We compared the contractile responses to vasoconstrictors in aortas from 20-to 22-week old
cardiomyopathic hamsters, BIO 53.58 strain, and age-matched F1b strain controls. Aortas …

Intracellular calcium concentration ([Ca2+] i) was measured with aequorin in ferret and rat
aortic strips contracted with phorbol esters. In ferret aorta, 12-deoxyphorbol 13-isobutyrate …

Effects of sodium nitroprusside (SNP) and forskolin on the contractile responses of aortic
strips to phorbol 12-myristate 13-acetate (PMA) were investigated in the present study. PMA …
