Members of prostaglandin (PG) E-series elicit cellular effects mainly through adenylyl cyclase-cAMP signaling. The role of PGE2-induced increase in cAMP has been shown to be compartmentalized in the cardiac myocytes: PGE2-induced increase of cAMP is not involved in the control of cardiomyocytic contraction. The purpose of the present study was to define the effect of PGE1 on the cGMP levels and the role of PGE1 in the atrial secretory function. Experiments were performed in perfused beating...

neonatal rat brain stem slices with the whole cell voltage clamp technique. In Mg2⁢ free condition, tetanus (10 stimuli at 10 Hz for 2 min) in the current clamp mode induced a robust LTD of isolated D, L-APV-sensitive postsynaptic currents (PSCs) for more than 30 min (n=6, 2.4⁑0.4% of the control), while isolated CNQX-sensitive PSCs were not suppressed (n=6, 95.3⁑1.6%). Tetanus also elicited similar LTD in the isolated GABAergic/glycinergic PSCs (n=5, 3.6⁑0.5%) and mixed...

McN-A-343 and cyclopiazonic acid was CNP＞NIF＞CTX. Also, the rank orders for high K⁢ and for DMPP were NIF＞CTX＞CNP and NIF＞CNP＞CTX, respectively. Taken together, these results demonstrate that all voltage-dependent Ca2⁢ channels (VDCCs) blockers of cilnidipine, nifedipine, and ω-conotoxin GVIA inhibit greatly the CA release evoked by stimulation of cholinergic (both nicotinic and muscarinic) receptors and the membrane depolarization without affecting the basal release from the...

mechanical threshold, and an increase in spontaneous flinchings and paw thickness, which are characteristics similar to those induced by whole bee venom. Melittin-induced nociception has been known to be modulated by the changes in the activity of excitatory amino acid receptors, voltage-dependent calcium channels, cyclooxygenase and serotonin receptors. The present study was undertaken to investigate the role of calcium chelators (TMB-8 & Quin 2) in melittin-induced nociceptive responses....

in the voltage range (⁣20 mV∼0 mV) for channel opening, suggesting an open channel interaction. Genistein (20μM) produced use-dependent block of Kv3.1 at a stimulation frequency of 1 Hz. The voltage dependence of steady-state inactivation of Kv3.1 was not changed by 20μM genistein. Our results indicate that genistein blocks directly Kv3.1 currents in concentration-, voltage-, time-dependent manners and the action of genistein on Kv3.1 is independent of tyrosine kinase inhibition.

Fluoxetine, widely used for the treatment of depression, is known to be a selective serotonin reuptake inhibitor (SSRI), however, there are also reports that fluoxetine has direct effects on several receptors. Employing whole-cell patch clamp techniques in rat brain slice, we studied the effects of fluoxetine on corticostriatal synaptic transmission by measuring the change in spontaneous excitatory postsynaptic currents (sEPSC). Acute treatment of rat brain slice with fluoxetine (10μM)...

voltage -dependent anion channel (VDAC)1, a cytochrome c releasing channel in mitochondria, were increased in SNP-treated cells, whereas were attenuated by EGCG. The enhancement of caspase-9, preceding mitochondria-dependent pathway, caspase-8 and death receptor-dependent pathway, as well as caspase-3 activities were suppressed by EGCG. SNP upragulated Fas and Fas-L, which are death receptor assembly, whereas EGCG ameliorated the expression of Fas enhanced by SNP. These results demonstrated that...

mechanical threshold and flinching behaviors were measured after the injection of WBV (0.04 mg or 0.1 mg/paw) and melittin (0.02 mg or 0.05 mg/paw) into the mid-plantar area of a rat hindpaw. MK-801 and CNQX (6-cyano-7-nitroquinoxaline-2,3-dione disodium) were administered intrathecally (i.t. 10μg) or i.pl.(15μg) 15 min before or i.t. 60 min after i.pl. WBV and melittin injection. Intrathecal pre- and post- administration of MK-801 and CNQX significantly attenuated the ability of high dose WBV...

Serotonin (5-hydroxytroptamine, 5-HT) has been shown to affect the induction of long-term potentiation (LTP) in the cortex such as the hippocampus, the visual cortex and the prefrontal cortex. Fluoxetine, as a selective serotonin reuptake inhibitor, is used in the management of a wide variety of psychological diseases. To study the effect of fluoxetine on the induction of LTP, we recorded the field potential in layer II/III of the frontal cortex from 3-wk-old. LTP was induced in horizontal input...

the basal release. However, at lower dose, cilnidipine did not affect CA release by membrane depolarization while at larger dose inhibited that. It seems likely that this inhibitory effect of cilnidipine is exerted by blocking both L- and N-type voltage-dependent Ca2⁢ channels (VDCCs) on the rat adrenomedullary chromaffin cells, which is relevant to inhibition of both the Ca2⁢ influx into the adrenal chromaffin cells and intracellular Ca2⁢ release from the cytoplasmic store. It...
