Cortical malformation-associated epileptic seizures are resistant to conventional anticonvulsant drugs. Relatively little research has been conducted on the effects of antiepileptic drugs (AEDs) on seizure activity in a rat model of dysplasia. We have used rats exposed to methylazoxymethanol acetate (MAM) in utero, an animal model featuring nodular heterotopia, to investigate the effects of ethosuximide (ETX) in the dysplastic brain. Pilocarpine was used to induce acute seizure in MAM-exposed...

In the present study, we developed a simple method to predict the neuronal cell death in the mouse hippocampus and striatum following transient global forebrain ischemia by evaluating both cerebral blood flow and the plasticity of the posterior communicating artery (PcomA). Male C57BL/6 mice were anesthetized with halothane and subjected to bilateral occlusion of the common carotid artery (BCCAO) for 30 min. The regional cerebral blood flow (rCBF) was measured by laser Doppler flowmetry. The...

can close. Genistein-induced block was voltage-dependent, increasing 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...

slightly decreased both mIPSC frequency and amplitude at 300μM concentration. Facilitatory effect of Zn2⁢ on GABAergic mIPSC frequency was occluded either in Ca2⁢-free external solution or in the presence of 100μM 4-aminopyridine, a non-selective K⁢ channel blocker. The results suggest that Zn2⁢ at lower concentrations depolarizes GABAergic nerve terminals by blocking K⁢ channels and increases the probability of spontaneous GABA release. This Zn2⁢-mediated...

Type I diabetes (T1D) is an organ-specific autoimmune disease caused by the T cell-mediated destruction of the insulin-producing β cells in the pancreatic islets. The onset of T1D is the consequence of a progressive destruction of islet β cells mediated by an imbalance between effector CD4⁢ T helper (Th)1 and regulatory CD4⁢ Th2 cell function. Since interferon-alpha (IFN-α) has been known to modulate immune function and autoimmunity, we investigated whether administration of...

an increase of [Ca2+]i in Ca2+-free/2 mM EGTA solution. Ratio-differences before and after the application of DTBNP after pretreatment with ATP or thapsigargin were 0.42⁑0.15 and 0.49⁑0.07, respectively (n=7), which are significantly reduced, compared to the control value of 0.72⁑0.07 in a Ca2+-free/2 mM EGTA solution. After the protonophore CCCP (10μM) challenge to release mitochondrial Ca2+, the similar result was obtained. Ratio-difference before and after the application...

In addition, short-term depression, recognized by paired-pulse ratio of excitatory postsynaptic currents, is significantly increased, indicating the increase of glutamate release probability at primary afferent terminals. The peripheral nerve injury also increases the amplitude, but not the frequency, of spontaneous inhibitory postsynaptic currents. These data support the hypothesis that peripheral nerve injury modifies spinal pain conduction and modulation systems to develop neuropathic pain.

difference in activation and inactivation kinetics of IBa by SS. Inhibitory effect of SS on IBa was significantly reduced by either dialysis of intracellular solution with GDPβS, a non-hydrolysableG protein inhibitor, or pretreatment with pertussis toxin (PTX). SS also decreased contraction of guinea-pig gastric antral smooth muscle. In conclusion, SS decreases voltage-dependent L-type calcium channel current (VDCCL) via PTX- sensitive signaling pathways in guinea-pig antral circular myocytes.

To prove the buffering contribution of mitochondria to the increase of intracellular Ca2+ level ([Ca2+]i) via background nonselective cation channel (background NSCC), we examined whether inhibition of mitochondria by protonophore carbonylcyanide m-chlorophenylhydrazone (CCCP) affects endothelial Ca2+ entry and Ca2+ buffering in freshly isolated rabbit aortic endothelial cells (RAECs). The ratio of fluorescence by fura-2 AM (R340/380) was measured in RAECs. Biological state was checked by...

We examined whether the abnormal EEG state by NMDA receptor blocker MK-801 can be reversed by typical and atypical antipsychotics differentially by comparing their spectral profiles after drug treatment in rats. The spectral profiles produced by typical antipsychotics chlorpromazine (5 mg/kg, i.p.) and haloperidol (0.5 mg/kg, i.p.) were differ from that by atypical antipsychotic clozapine (5 mg/kg, i.p.) in the rats treated with or without MK-801 treatment (0.2 mg/kg, i.p.) which produce...
