The present study was attempted to investigate the effect of cilnidipine (FRC-8635), which is a newly synthesized novel dihydropyridine (DHP) type of organic Ca2⁢ channel blockers, on secretion of catecholamines (CA) evoked by acetylcholine (ACh), high K⁢, DMPP and McN-A-343 from the isolated perfused rat adrenal gland. Cilnidipine (1∼10μM) perfused into an adrenal vein for 60 min produced relatively dose- and time-dependent inhibition in CA secretory responses evoked by ACh...

Soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNARE) proteins, composed of two presynaptic membrane proteins [synaptosomal-associated protein of 25 kDa (SNAP-25) and syntaxin] and a presynaptic vesicular protein [vesicle-associated membrane protein (VAMP)], serve as a core of exocytotic fusion machinery, which can be affected by ischemia. Synaptic protein in core region, striatum and cortex has been shown to alter after focal ischemia, however, little is known in...

People in tropics have the ability to tolerate heat by residential permanence in the tropics. Previously, we have shown that African and Thai subjects who lived for whole their lives in only their respective countries sweat less under hot conditions than South Koreans who also lived whole their lives in Korea. The difference in sweating responses was attributed to the dissimilar central and peripheral sweating mechanisms operating in people from both groups. In the present study, acetylcholine...

characteristics of the rostral gustatory nucleus of the tractus solitarius and distribution of NO synthases (NOS). Neuronal NOS (nNOS) immunoreactivity was strongly detected along the solitary tract extending from rostral to caudal medulla. Resting membrane potentials of NTS neurons were ⁣49.2⁑2 mV and action potential amplitudes were 68.5⁑2 mV with a mean duration measured at half amplitude of 1.7⁑0.3 ms. Input resistance, determined from the response to a 150 ms,...

Transient forebrain ischemia results in the delayed neuronal death in the CA1 area of the hippocampus. The present study was performed to determine effects of aminoguanidine, a selective iNOS inhibitor, on the generation of peroxynitrite and delayed neuronal death occurring in the hippocampus following transient forebrain ischemia. Transient forebrain ischemia was produced in the conscious rats by four-vessel occlusion for 10 min. Treatment with aminoguanidine (100 mg/kg or 200 mg/kg, i.p.) or...

Ca2⁢ influx appears to be important for triggering myoblast fusion. It remains, however, unclear how Ca2⁢ influx rises prior to myoblast fusion. Recently, several studies suggested that NMDA receptors may be involved in Ca2⁢ mobilization of muscle, and that Ca2⁢ influx is mediated by NMDA receptors in C2C12 myoblasts. Here, we report that other types of ionotropic glutamate receptors, non-NMDA receptors (AMPA and KA receptors), are also involved in Ca2⁢ influx in...

We previously shown that LES contraction depends on M3 receptors linked to PTX insensitive Gq protein and activation of PLC. This results in production of IP3, which mediates calcium release, and contraction through a CaM dependent pathway. In the esophagus ACh activates M2 receptors linked to PTX sensitive Gi3 protein, resulting in activation of PLD, presumably, production of DAG. We investigated the role of PLC isozymes which can be activated by Gq or Gβ protein on ACh-induced contraction in...

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...

on the NHE activity and counterbalance by dopamine. Our data strongly suggested that chronic dopamine treatment increased intrinsic intracellular buffer capacity, since higher buffer capacity was induced by lower resting pHi and this effect could attenuate pHi changes under extracellular Na⁢-free conditions in chronically dopamine-treated cells. Our study also demonstrated that intracellular acidification induced by chronic dopamine treatments was not mediated by changes in NHE activity.

We have studied mutant forms of Kir2.1 in which an aspartate residue (D172), important for gating by intracellular polyamines, is replaced by one of three basic residues (Arg, Lys or His). Such channels are highly selective for K+, but show inward rectification that is a shallow function of voltage compared with that found in wild type. This inward rectification occurs with a reduced affinity for spermine and persists in the absence of polyamines. Though the unitary current-voltage relation...
