Modulation of ATP-Induced Activation of the Muscarinic K+ Channel Activity by Protein Kinase C
Yang-MiKim, Hong-KiPark, Jae-HeeHan, Choon-OkPark, Seong-GeunHong 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 11 Pages

The atrial acetylcholine-activated K (KACh) channel is gated by the pertussis toxin-sensitive inhibitory G (GK) protein. Earlier studies revealed that ATP alone can activate the KACh channel via transphosphorylation mediated by nucleoside-diphosphate kinase (NDPK) in atrial cells of rabbit and guinea pig. This channel can be activated by various agonists and also modulated its function by phosphorylation. ATP-induced KACh channel activation (AIKA) was maintained in the presence of the... -
흰쥐 해마에서 Acetylcholine 유리에 미치는 Adenosine 및 Magnesium의 영향
최봉규(Bong Kyu Choi), 윤영복(Young Bok Yoon) 대한약리학회 대한약리학잡지 8 Pages

흰쥐 해마 (hippocampus)에서 acetylcholine(ACh) 유리에 미치는 adenosine 및 이에 미치는 magnesium의 역할에 관한 지견을 얻고자하여 [3H]-choline으로 평형시킨 해마 slice를 사용하여 [3H]-ACh 유리에 미치는 여러가지 약물들의 영향을 관찰하였다. Adenosine *0.3 ~ 100μM)은 전기자극 (3 Hz, 5 Vcm-1, 2 ms, rectangular pulses)에 의한 [3H]-ACh 유리를 용량 의존적으로 감소시켰다. A1-adenosine 수용체 차단제인 8-cyclopentyl-1, 3-dipropylxanthine (DPCPX, 1-10μM)은 용량 의존적으로 [3H]-ACh 유리를 증가시켰으며,... -
흰쥐 해마에서 Acetylcholine 유리에 미치는 N6-Cyclopentyladenosine 및 Forskolin의 영향

흰쥐 해마(hippocampus)에서 acetylcholine(Ach) 유리에 미치는 A1-adenosine 수용체의 역할과 post-receptor 기전에 있어서 adenylate cyclase 계의 관여여부에 관한 지견을 얻고자 하여 [3H]-choline으로 평형시킨 해마 slice를 사용하여 [3H]-ACh 유리에 미치는 여러가지 약물들의 영향을 관찰하였다. A1-adenosine 수용체 흥분제인 N6-cyclopentyladenosine(CPA, 0.1 ~ 10μM)은 전기자극(3Hz, 5 Vcm-1, 2 ms, rectangular pulses)에 의한 [3H]-ACh 유리를 용량 의존적으로 감소시켰다. A1-adenosine 수용체 차단제인... -
가토 해마에서 Acetylcholine 유리에 미치는 Oxotremorine 및 Forskolin의 영향

가토 해마(hippocampus)에서 acetylcholine(ACh) 유리에 미치는 cAMP의 역할에 관한 지견을 얻고자하여 [3H]-choline으로 평형시킨 해마 slice 및 시냅토솜(synaptosome)을 사용하여 [3H]-ACh 유리에 미치는 여러가지 약물들의 영향을 관찰하였다. Adenylate cyclase 활성화제인 forskolin(0.1 ~ 30μM)은 전기 및 고농도 K+ 자극에 의한 [3H]-ACh 유리를 용량 의존적으로 증가시켰으며, dbcAMP 또한 ACh 유리를 강화시켰다. Muscarine성 흥분제인 oxotremorine(0.1 ~ 30μM)은 전기 및 K+ 자극에 의한 [3H]-ACh 유리 효과를 용량... -
Time-course changes of hippocalcin expression in the mouse hippocampus following pilocarpine-induced status epilepticus
Hee-Soo Choi, Choong-Hyun Lee* 대한수의학회 Journal of Veterinary Science 8 Pages
대한수의학회 Journal of Veterinary Science 2016, 제 17권 제 2호 2 137-144 (8 pages)
Hippocalcin participates in the maintenance of neuronal calcium homeostasis. In the present study, we examined the time-course changes of neuronal degeneration and hippocalcin protein level in the mouse hippocampus following pilocarpine-induced status epilepticus (SE). Marked neuronal degeneration was observed in the hippocampus after SE in a time-dependent manner, although neuronal degeneration differed according to the hippocampal subregions. Almost no hippocalcin immunoreactivity was detected... -
Effects of mosapride on motility of the small intestine and caecum in normal horses after jejunocaecostomy

The purpose of the present study was to evaluate the prokinetic effects of mosapride with non-invasive assessment of myoelectrical activity in the small intestine and caecum of healthy horses after jejunocaecostomy. Six horses underwent celiotomy and jejunocaecostomy, and were treated with mosapride (treated group) at 1.5 mg/kg per osos once daily for 5 days after surgery. The other six horses did not receive treatment and were used as controls (non-treated group). The electrointestinography... -
Mechanism of UV light-induced photorelaxation in isolated rat aorta

Isolated rat thoracic aorta which is pharmacologically precontracted by phenylephrine induces photorelaxation when exposed to long wave length UV-light. The aim of the present study was to characterize the mechanism of UV-light induced by photorelaxation in the rat aorta. 1. UV light relaxed both endothelium-intact and -denuded rat aortic rings contracted by phenylephrine. The magnitude of relaxation on UV light was dependent on the exposure time and slightly greatly in endothelium-denuded rings... -
Tricyclic antidepressant amitriptyline inhibits 5-hydroxytryptamine 3 receptor currents in NCB-20 cells

receptor therapeutic potentials. Using a whole-cell voltage clamp method, we recorded the currents of the 5-HT3 receptor when 5-HT was applied alone or co-applied with amitriptyline in cultured NCB-20 neuroblastoma cells known to express 5-HT3 receptors. To elucidate the mechanism of amitriptyline, we simulated the 5-HT3 receptor currents using Berkeley Madonna？？ software and calculated the rate constants of the agonist binding and receptor transition steps. The 5-HT3 receptor currents were...
