Frequency-force relationships (FFR) were studied in electrically field stimulated rat left atria (LA) by reducing the stimulation frequency from resting 3 Hz to test frequencies (0.1-1 Hz) for 5 minutes. The twitch amplitudes of LA elicited the typical negative staircases with 3-phased changes: the initial rapid increase, the second decrease and the following plateau at test frequencies. Verapamil (3⁓10⁣5 M) pretreatment elicited frequency-dependent suppression of the twitch...

the lavage fluid obtained from silica-treated rats, indicating silica-induced acute lung injury. Northern blot analysis demonstrated that the steady state levels of iNOS mRNA in broncho-alveolar lavage cells were increased following silica treatment. The productions of nitrite and nitrate in the cultured cells were significantly increased by 2-fold following silica treatment, respectively, which were attenuated by the NOS inhibitor Nω-nitro-L-arginine-methyl ester(L-NAME) and partially reversed...

added to the solution perfusing through the aortic segment. Hypoxia was evoked by switching the solution aerated with 95% O2/5% CO2 mixed gas to one aerated with 95% N2/5% CO2 mixed gas. When the contraction induced by prostaglandin F2α reached a steady state, the solution was exchanged for hypoxic one. And then, hypoxia and reoxygenation were interchanged at intervals of 2 minutes (intermittent hypoxia). The endothelial cells were also exposed to single 10-minute hypoxia (continuous hypoxia)....

ATP-sensitive K+ channels (KATP) were not identified in gastric smooth muscle cells. However， in tension recording of intact gastric circular muscle， lemakalim of KATP channels opener in other tissues suppressed mechanical contractions and this effect was blocked by glibenclamide， a specific inhibitor of KATP channels. The aims of this study were to investigate whether KATP channels exist in gastric smooth muscle of guinea-pig and to know its physiological role. Whole cell K'+ curr‘ents...

Two types of delayed rectifier and three types of transient potassium currents were identified according to their electrophysiological properties. The delayed rectifier currents were named IKe (early inactivating) and IKl (late inactivating). Steady state inactivation of IKe began from -100 mV lasting until ⁣20 mV. IKl could be distinguished from IKe by its inactivation voltage range, from -70 mV to +10 mV. Three transient currents were named IAf (fast inactivation), IAi (intermediate...

The effects of pH on K⁢ currents were investigated in single smooth muscle cells isolated from the thoracic aorta of Wistar-Kyoto rats. Whole-cell K⁢ currents were recorded in the conventional configuration of the voltage-clamp technique. Pinacidil (10uM) activated the whole-cell current and the pinacidil-activated current was completely inhibited by glibenclamide (10uM) , an inhibitor of ATP-sensitive K⁢ channel (KATP channel). Pinacidil-activated current was reversed at near...

Although one of the major physiological functions of taurine(2-aminoethanesulfonic acid) is the inhibitory action on the central nervous system(CNS), the mechanism of taurine in controlling the neuronal excitation in the CNS has been in controversy. Electrically evoked pEPSP and spontaneous activity induced by the perfusion of low Mg⁢⁢-ACSF were recorded in the CA1 pyramidal cell layer of the hippocampal slice. To test the inhibitory effect of taurine on spontaneous responses,...

of AA (1, 5 and 10 ㄍM) (P＞0.05). Unsaturated fatty acids shifted the steady-state inactivation curves of IBa to the left; the extent of shift caused by AA was greater than that caused by LA. The activation curve was not affected by AA or LA. The results suggest that AA and other unsaturated fatty acids directly modulate L-type calcium channels and AA might modulate the hyposmotic stretch- induced increase of L-type calcium channel current in guinea-pig gastric smooth muscle.

In the present study, we characterized the angiotensin II (AII)-induced relaxations in the phenylephrine- precontracted rabbit mesenteric arteries with endothelium. 1) AII-induced relaxation was consistently observed in the rabbit mesenteric arteries with and without endothelium, but not in the aortic segment with endothelium. 2) AII-induced endothelium-dependent relaxation was markedly inhibited by Nw-nitro- L-arginine (L-NNA, 100 ㄍM), methylene blue (10 ㄍM) and LY83583 (10...
