An important property of the intestine is the ability to secrete fluid. The intestinal secretion is regulated by a number of substances including vasoactive intestinal peptide (VIP), ATP and different inflammatory mediators. One of the most important secretagogues is adenosine during inflammation. However, the controversy concerning the underlying mechanism of adenosine-stimulated Cl⁣ secretion in intestinal epithelial cells still continues. To investigate the effect of adenosine on...

The spontaneous contractions of gastric smooth muscles are regulated by slow waves, which are modulated by both nervous system and humoral agents. This study was designed to examine the effects of prostaglandin E2 (PGE2) on the contractile and electrical activities of antral smooth muscles in guinea-pig stomach, using an intracellular recording technique. To elucidate the underlying mechanism for its effect on contractility, ionic currents were also measured using a whole-cell patch clamp...

In gastrointestinal smooth muscle, muscarinic stimulation by carbachol (CCh) activates nonselective cation channel current (ICCh) which is facilitated by intracellular [Ca2⁢] increase. Caffeine is widely used in experiments to mobilize Ca2⁢ from intracellular stores. This study shows a strong inhibitory effect of caffeine on ICCh in guinea-pig gastric myocyte. In this study, the underlying mechanism of the inhibitory effect of caffeine was investigated. ICCh was completely...

To investigate the possible involvement of outward potassium (K+) currents in nitric oxide-induced relaxation in intestinal smooth muscle, we used whole-cell patch clamp technique in freshly dispersed guinea-pig ileum longitudinal smooth muscle cells. When cells were held at ⁣60 mV and depolarized from ⁣40 mV to ⁢50 mV in 10 mV increments, sustained outward K+ currents were evoked. The outward K+ currents were markedly increased by the addition of 10 ㄍM sodium...

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...

In the present study, we have investigated the effect of metabolic inhibition on the inward rectifier K current (IK1). Using whole cell patch clamp technique we applied voltage ramp from ⁢80 mV to ⁣140 mV at a holding potential of ⁣30 mV and recorded the whole cell current in single ventricular myocytes isolated from the rabbit heart. The current-voltage relationship showed N-shape (a large inward current and little outward current with a negative slope) which is a...

Loss of synaptic transmission and accumulation of extracellular K⁢([K⁢]O) are the key features in ischemic brain damage. Here, we examined the effects of several K⁢channel modulators on the early ischemic changes in population spike (PS) and [K⁢]o in the CA1 pyramidal layer of the rat hippocampal slice using electrophysiological techniques. After onset of anoxic aglycemia (AA), orthodromic field potentials decreased and disappeared in 3.3⁑0.22 min (mean⁑SEM,...

Intracellular recordings of oscillatory firing (bursting activity) were obtained from Purkinje cells (PCs) in rat cerebellar slices. Apamin inhibited post-burst hyperpolarizations (PBHs) progressively and finally terminated oscillatory firing activity of PCs. Apamin did not affect the amplitude or duration of the after-hyperpolarization (AHP) between spikes within the burst. In the voltage clamp mode, apamin shifted the whole-cell, quasi-steady state I/V relationship in an inward direction and...

Unilateral labyrinthectomy (ULX) causes autonomic symptoms, ocular and postural asymmetries, which disappear over time in the process of equilibrium recovery known as vestibular compensation. In the present study, in order to elucidate mechanisms responsible for the effects of electrical stimulation on vestibular compensation and investigate the relationship between vestibular compensation and c-Fos expression in the medial vestibular nuclei following ULX, we measured spontaneous nystagmus, eye...
