Background: Recent in vivo experimental evidence suggests that isoflurane-induced cardioprotection may involve KATP channel activation. However, it was demonstrated that isoflurane inhibited KATP channel activities in the inside-out patch mode. To explain this discrepancy, the present investigation tested the hypothesis that a metabolite of isoflurane, trifluoroacetic acid (TFA), contributes to isoflurnae-induced cardioprotection via KATP channel activation during myocardial ischemia and...

the isolated rat ventricular myocytes, stimulation with the voltage protocol roughly mimicked action potential generated a large inward current which was partially blocked by nifedipine or Na⁢ current inhibition. 0 Ca application suppressed the inward current by 39⁑4% while the current was further suppressed after 0 Na-0 Ca application by 53⁑3%. Caffeine increased this inward current by 44⁑3% in spite of 14 mM EGTA. Finally, the Na⁢ current-dependent fraction of the...

Stimulation of muscarinic receptors by carbachol (CCh) in the circular smooth muscle of the guinea pig gastric antrum causes muscle contraction. In the present study, muscarinic receptor subtype controlling the muscle contraction in response to CCh was studied using putative muscarinic receptor antagonists. Isometric force of the isolated circular muscle strips was measured in an organ bath. CCh contracted the muscle in a dose-dependent way, and each of the three muscarinic receptor...

Chronic exposure to cadmium (Cd) results in an inhibition of protein endocytosis in the renal proximal tubule, leading to proteinuria. In order to gain insight into the mechanism by which Cd impairs the protein endocytosis, we investigated the effect of Cd on the acidification of renal cortical endocytotic vesicles (endosomes). The endosomal acidification was assessed by measuring the pH gradient-dependent fluorescence change, using acridine orange or FITC-dextran as a probe. In renal endosomes...

ATP-sensitive potassium channels (KATP channels) play an important role in insulin secretion from pancreatic beta cells. We have investigated the effect of propofol on KATP channels in cultured single pancreatic beta cells of rats. Channel activity was recorded from membrane patches using the patch-clamp technique. In the inside-out configuration bath-applied propofol inhibited the KATP channel activities in a dose-dependent manner. The half-maximal inhibition dose (ED50) was 48.6⁑8.4μM...

of the action potential, its firing threshold and the resting membrane potential. In this study, whole cell configuration of patch clamp technique had been applied to record the blocking effect of capsaicin, a lipophilic alkaloid, on the delayed rectifier K⁢ current in cultured small diameter DRG neurons of adult rat. Capsaicin reduced the amplitude of K⁢ current in dose dependent manner, and the concentration-dependence curve was well described by the Hill equation with KD value of...

The aim of the present study is to investigate the contribution of Ca2⁢-activated K⁢ (KCa) channels and delayed rectifier K⁢ (KV) channels to the resting membrane potential (RMP) in rabbit middle cerebral arterial smooth muscle cells. The RMP and membrane currents were recorded using the whole-cell patch configuration and single KCa channel was recorded using the outside-out patch configuration. Using the pipette solution containing 0.05 mM EGTA, the RMP was...

scavengers did not alter the ethanol effect. A potent antioxidant DPPD and iron chelators did not prevent the inhibition. Pyrazole, an inhibitor of alcohol dehydrogenase, did not attenuate ethanol-induced inhibition of Na⁢-Pi uptake, but it prevented ethanol-induced cell death. These results suggest that ethanol may inhibit Na⁢-Pi uptake through a direct action on the carrier protein, although the transport system is affected by alterations in the lipid environment of the membrane.

Contribution of prostaglandins D2, E2 and I2 (PGD2, PGE2 and PGI2) on the regulation of ATP-sensitive K⁢ channel (KATP channel) was investigated in isolated single rat ventricular cardiac myocytes using the patch clamp technique. PGD2, PGE2 and PGI2 did not affect KATP channel activity in the inside-out patch, but increased channel activity in a dose-dependent manner when the channel activities were attenuated by the administration of 100 μM ATP to the internal solution in the inside-out...

This study was designed to evaluate the efficacy of dynamic parameters, such as correlation dimension D2, by comparing spectral electroencephalographic (EEG) parameters. These parameters are used to estimate the depth of halothane anesthesia as defined by the presence of body movement in response to a tail clamp. Six rats were used and each of them was exposed to halothane sequentially at the concentrations of 0%, 0.5%, 1.0% and 1.5% for 30 min. A tail clamp was applied every five min and the...
