There are numerous studies on transepithelial transports in duct cells including Cl⁣ and/or HCO3⁣. However, studies on transepithelial K⁢ transport of normal duct cells in exocrine glands are scarce. In the present study, we examined the characteristics of K⁢ currents in single duct cells isolated from guinea pig pancreas, using a whole-cell patch clamp technique. Both Cl⁣ and K⁢ conductance were found with KCl rich pipette solutions. When the bath solution...

The pelvic ganglia provide autonomic innervations to the various urogenital organs, such as the urinary bladder, prostate, and penis. It is well established that both sympathetic and parasympathetic synaptic transmissions in autonomic ganglia are mediated mainly by acetylcholine (ACh). Until now, however, the properties of ACh-induced currents and its receptors in pelvic ganglia have not clearly been elucidated. In the present study, biophysical characteristics and molecular nature of nicotinic...

We developed a cardiac cell model to explain the phenomenon of mechano-electric feedback (MEF), based on the experimental data with rat atrial myocytes. It incorporated the activity of ion channels, pumps, exchangers, and changes of intracellular ion concentration. Changes in membrane excitability and Ca2⁢ transients could then be calculated. In the model, the major ion channels responsible for the stretch-induced changes in electrical activity were the stretch-activated channels (SACs)....

pA hyperpolarizing current pulse, was 385⁑15 MΩ. Superfusion of SNAP or SNP, NO donors, produced either hyperpolarization (68%), depolarization (5%), or no effect (27%). The hyperpolarization was mostly accompanied by a decrease in input resistance. The hyperpolarization caused by SNAP or SNP increased the time to initiate the first action potential, and decreased the number of action potentials elicited by current injection. SNP or SNAP also markedly decreased the number of firing neural...

It has been demonstrated that an unidentified cytosolic factor(s) reduces KACh channel function. Therefore, this study attempted to elucidate the cytosolic factor. Fresh cytosol isolated from normal heart (FC) depressed the KACh channel activity, but cytosol isolated from the ischemic hearts (IC) did not modulate the channel function. Electrophorectic analysis revealed that a protein of ∼80 kDa was markedly reduced or even lost in IC. By using peptide sequencing analysis and Western blot, this...

Metabotropic glutamate receptors (mGluRs), classified into three groups (group I, II, III), play a critical role in modulation of synaptic transmission at central and peripheral synapses. In the present study, extracellular field potential recording techniques were used to investigate effects of mGluR agonists on excitatory synaptic transmission at thalamic input synapses onto the lateral amygdala. The non-selective mGluR agonist t-ACPD (100μM) produced reversible, short-term depression, but...

chronic dopamine treatments. The initial rate and the amplitude of intracellular acidification by isosmotical Na⁢ removal from the bath medium in chronically dopamine-treated cells were much smaller than those in control. Although it seemed to be attenuated in Na⁢-dependent pH regulation system, Na⁢-dependent pHi recovery by NHE after intracelluar acid loading in the dopamine-treated groups was not significantly different from the control. The result is interpreted to be due to...

The aim of the present study was to examine the effects of platycodin D and D3, which are active components derived from the roots of Platycodon grandiflorum A. DC., on the contractile force of the i3olated rat aorta and blood pressure of the anesthetized rat, and also to elucidate its mechanism of action. Both phenylephrine (an adrenergic α1-receptor agonist) and high potassium (a membrane- depolarizing agent) caused great contractile responses in the isolated aortic strips. Platycodin D at...

The basic mechanism for the excitation of the peripheral vestibular receptors following acute hypotension induced by sodium nitroprusside (SNP) or hemorrhage was investigated in anesthetized rats. Electrical activity of the afferent vestibular nerve was measured after pretreatment with kynurenic acid, an NMDA receptor antagonist. The activity of the vestibular nerve at rest following acute hypotension induced by SNP or simulating hemorrhage was a greater increase than in control animals. The...

Ion channel inhibitors are widely used for pharmacological discrimination between the different channel types as well as for determination of their functional role. In the present study, we tested the hypothesis that 4-aminopyridine (4-AP) could affect the large conductance Ca2⁢-activated K⁢ channel (BKCa) currents using perforated-patch or cell-attached configuration of patch-clamp technique in the rabbit pulmonary arterial smooth muscle. Application of 4-AP reversibly inhibited the...
