Noradrenergic Modulation of Spontaneous Inhibitory Postsynaptic Currents in the Hypothalamic Paraventricular Nucleus
LongHwaLee, WoneeChong, KihoLee, JinBongPark, PanDongRyu 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 10 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2002, Vol.6 No.2 2 71-80 (10 pages)
Previous studies have suggested that brain stem noradrenergic inputs differentially modulate neurons in the paraventricular nucleus (PVN). Here, we compared the effects of norepinephrine (NE) on spontaneous GABAergic inhibitory postsynaptic currents (sIPSCs) in identified PVN neurons using slice patch technique. In 17 of 18 type I neurons, NE (30∼100μM) reversibly decreased sIPSC frequency to 41⁑7% of the baseline value (4.4⁑0.8 Hz, p＜0.001). This effect was blocked by yohimbine... -
Nimodipine as a Potential Pharmacological Tool for Characterizing R-Type Calcium Currents
SeogBaeOh 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 9 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2001, Vol.5 No.6 8 511-519 (9 pages)
Nimopidine, one of dihydropyridine derivatives, has been widely used to pharmacologically identify L-type Ca currents. In this study, it was tested if nimodipine is a selective blocker for L-type Ca currents in sensory neurons and heterologous system. In mouse dorsal root ganglion neurons (DRG), low concentrations of nimodipine (＜10μM), mainly targeting L-type Ca currents, blocked high-voltage-activated calcium channel currents by ∼38%. Interestingly, high concentrations of nimodipine... -
Modulation of L-type Ca2+ Channel Currents by Various Protein Kinase Activators and Inhibitors in Rat Clonal Pituitary GH3 Cell Line
YoungMinBae, Hye-JungBaek, HanaCho, YungEEarm, Won-KyungHo 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 8 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2001, Vol.5 No.2 4 139-146 (8 pages)
L-type Ca2 channels play an important role in regulating cytosolic Ca2 and thereby regulating hormone secretions in neuroendocrine cells. Since hormone secretions are also regulated by various kinds of protein kinases, we investigated the role of some kinase activators and inhibitors in the regulation of the L-type Ca2 channel currents in rat pituitary GH3 cells using the patch-clamp technique. Phorbol 12,13-dibutyrate (PDBu), a protein kinase C (PKC) activator, and... -
The Role of K+ Channels on Spontaneous Action Potential in Rat Clonal Pituitary GH3 Cell Line
HyewhonRhim, Hye-JungBaek, Won-KyungHo, YungEEarm 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 10 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2000, Vol.4 No.2 1 81-90 (10 pages)
The types of K channel which determine the pattern of spontaneous action potential (SAP) were investigated using whole-cell variation of patch clamp techniques under current- and voltage-clamp recording conditions in rat clonal pituitary GH3 cells. Heterogeneous pattern of SAP activities was changed into more regular mode with elongation of activity duration and afterhyperpolarization by treatment of TEA (10 mM). Under this condition, exposure of the class III antiarrhythmic agent E-4031... -
Effect of Propofol, an Intravenous Anesthetic Agent, on KATP Channels of Pancreatic β-cells in Rats
EunJeePark, Dae-KyuSong, JaeKyuCheun, JungInBae, Won-KyungHo, YungEEarm 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 7 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2000, Vol.4 No.1 4 25-31 (7 pages)
ATP-sensitive potassium channels (KATP channels) play an important role in insulin secretion from pancreatic beta cells. We have investigated the effect of propofol on KATP channels in cultured single pancreatic beta cells of rats. Channel activity was recorded from membrane patches using the patch-clamp technique. In the inside-out configuration bath-applied propofol inhibited the KATP channel activities in a dose-dependent manner. The half-maximal inhibition dose (ED50) was 48.6⁑8.4μM... -
The Effects of Sera from Amyotrophic Lateral Sclerosis Patients on Neuromuscular Transmission and Calcium Channels in Mice
HaiDunYan, JimokKim, SungJunJung, JunKim 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 17 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 1999, Vol.3 No.1 13 101-117 (17 pages)
Amyotrophic lateral sclerosis (ALS) is a degenerative neuromuscular disease of unknown etiology in which the upper and lower motor neurons are progressively destroyed. Recent evidences support the role of autoimmune mechanisms in the pathogenesis of ALS. This study investigated the effects of sera from ALS patients on neuromuscular transmission in phrenic nerve-hemidiaphragm preparations and on calcium currents of single isolated dorsal root ganglion (DRG) cells in mice. Mice were injected with... -

Two Types of Voltage-dependent Outward Potassium Currents in Smooth Muscle Cells of Rabbit Basilar Atery
TongMookKang, InsukSo, DaeYongUhm, KiWhanKim 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 15 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 1997, Vol.1 No.2 7 169-183 (15 pages)
We have investigated the two types of voltage-dependent outward potassium (K) currents, i.e. delayed rectifier K current (IK(V)) and 'A-like' transient outward K current (Ito) with patch-clamp technique in single smooth muscle cells (SMCs) isolated from rabbit basilar artery, and investigated the characteristics of them. The time-courses of activation were well fitted by exponential function raised to second power (n2) in IK(v) and fourth power (n4) in Ito. The activation, inactivation and... -
Electroencephalogram Power Spectra in Thioacetamide-induced Hepatic Encephalopathy
김지희(Chi Hui Kim), 최원진(Won Jin Choi), 박정숙(Jung Sook Park), 이향이(Hyang Yi Lee), 하정희(Jeoung Hee Ha), 이만기(Maan Gee Lee) 대한약리학회 대한약리학잡지 8 Pages

During the development of hepatic encephalopathy after thioacetamide (TAA) injection to rat, EEG was recorded at two different states: without or with tactile stimulation of tail at regular intervals. Calculations based on the spectral and band analysis were used. The changes in the power spectra and bands were examined in 3 different behavioral stages: normal, mild ataxia and severe ataxia. In normal rats, the stimulation produced the increase in the power of the theta (3.5 ~ 8 Hz) and the... -

급성 신성 고혈압쥐 (2-kidney, 1-ligation type)의 전신성 동맥계와 폐 동맥계에 대한 내피 의존적 혈관반응성을 규명하기 위하여, 적출 혈관 및 마취상태의 흰쥐에 대한 acetylcholine (ACh)의 혈관이완작용 및 혈압강하 작용을 측정하였다. 혈장 renin 활성(PRA)은 신동맥 결찰전 7.31 ± 0.63 ng/ml/hr A I에 비해 결찰 6 ~ 8일후에는 19 ~ 22 ng/ml/hr A I으로 유의성있게 증가하였으며, 이는 수축기혈압의 상승과 (154 ± 1.83{\rightarrow}190 ~ 215 mmHg) 일정한 상관성을 유지하였다. 신성 고혈압쥐 및 정상 혈압쥐의 흉곽...
