KoonHeeHan, GapJinCheon, DongSooYeon, SeongChunKwon 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 6 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2009, Vol.13 No.3 8 189-194 (6 pages)
This study was designed to clarify the mechanism of the inhibitory effect of forskolin on contraction, cytosolic Ca2＋ level ([Ca2＋]i), and Ca2＋ sensitivity in guinea pig ileum. Forskolin (0.1 nM∼10ՌM) inhibited high K＋ (25 mM and 40 mM)- or histamine (3ՌM)-evoked contractions in a concentration- dependent manner. Histamine-evoked contractions were more sensitive to forskolin than high K＋- evoked contractions. Spontaneous changes in [Ca2＋]i and contractions were inhibited by... -

SOM in nociception. In the current study, the effects of SOM were investigated using anesthetized cats. Specifically, the responses of rostrally projecting spinal dorsal horn neurons (RPSDH neurons) to different kinds of noxious stimuli (i.e., heat, mechanical and cold stimuli) and to the AՄ-and C-fiber activation of the sciatic nerve were studied. Iontophoretically applied SOM suppressed the responses of RPSDH neurons to noxious heat and mechanical stimuli as well as to C-fiber activation... -
Effects of Arachidonic Acid on the Calcium Channel Current (IBa) and on the Osmotic Stretch-induced Increase of IBa in Guinea-Pig Gastric Myocytes

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 1997, Vol.1 No.4 10 435-443 (9 pages)
We employed the whole-cell patch clamp technique to investigate the effects of arachidonic acid (AA) on barium inward current through the L-type calcium channels (IBa) and on osmotic stretch-induced increase of IBa in guinea-pig antral gastric myocytes. Under isosmotic condition, AA inhibited IBa in a dose-dependent manner to 91.1⁑1.4, 72.0⁑3.2, 46.0⁑1.8, and 20.3⁑2.3% at 1, 5, 10, 30 mM, respectively. The inhibitory effect of AA was not affected by 10 ㄍM... -

본 연구실에는 최근 수년동안 말라리아, 성병등에 민간약으로 사용되어 온 회양목(Buxus microphylla var. koreana Nakai)으로 부터 다수의 물질을 분리하여 그 약리작용을 경색하여왔다. Coumarin의 유도체인 buxuletin은 이뇨 작용이 있음이 인정되었으며, steroid 성 alkaloid인 Cyclobuxine D(C25H42ON2)는 항염증작용, 흰쥐에서 심박동수 감소작용 및 적출 평활근 이완 작용을 나타냈다. 본 연구에서는 회양목에서 Cyclobuxine D의 유도체인 Cyclobuxine E(C24H38ON2)를 분리하여 그 구조를 이화학적인 방법으로 규명하였으며 흰쥐의... -
동맥근 수축에 대학 Oxybutynin의 이완효과에 관한 연구

돼지 우관상동백을 적출하여 항경련제인 oxybutynin의 약리작용을 조사하였다. 1. Acetylcholine (ACh)과 KCl은 관상동맥을 수축시켰고 이 수축효과는 용량의존적이었다. ACh의 수축효과는 내피손상표본 (EC50=0.52μM)에서 내피표본 (EC50=0.52μM)보다 약 2배 강화되있으나 KCl의 수축효과는 양군간에 차이가 없었다. 2. ACh(1.0μM)의 수축효과는 oxybutynin과 atropine에 의 하여 용량의존적으로 억제되었고 두 약물의 (IC50는 각각 11.0 nM과 0.47 nM로 atropine이 약 23배나 더 예민하였다. 그러나 KCl (35 mM)의 수축효과는... -
적출 가토 심장에 있어서 수축빈도-수축력 상관관계에 대한 Higenamine의 강심 효과
장기철(Ki Churl Chang) 대한약리학회 대한약리학잡지 8 Pages
대한약리학회 대한약리학잡지 1983, 제 19권 제 2호 2 9-16 (8 pages)
현재 사용되고 있는 강심제로는 디지탈리스 배당체가 유일한 약물이지란 그 안전역이 대단히 좁아서 보다 안전한 강심제의 개발이 요구되고 있다. 최근 강심작용이 현저할 뿐 아니라 안전역이 비교적 넓을 것으로 인정되는 higenamine이 개발되어 그 작용기전을 밝히려는 시도가 많이 있었다. 본 연구에서는 higenamine의 강심작용 기전을 규명하기 위한 연구의 일환으로 수축빈도-수축력 상관관계(interval-strength relationship)에 있어서 1) Rested-state수축력 2) Positive inotropic effect of activation(PIEA) 3) Negative... -
Effects of Noradrenaline on the Spontaneous Contraction and Ionic Current in the Antral Circular Muscle of Guinea-pig Stomach

There is evidence that noradrenaline enhances spontaneous contractions dose-dependently in guinea-pig antral circular muscle. To investigate the mechanism of this excitatory action, slow waves and membrane currents were recorded using conventional microelectrode techniques in muscle strips and the whole cell patch clamp technique in isolated gastric myocytes. On recording slow waves, noradrenaline (10-5 M) induced the hyperpolarization of the membrane potential, although the shape of the slow... -
Effects of pH, PCO2, and Adenosine on the Contractility of Pig Coronary Artery
Chang, Seok-Jong, Kim, Il-Seon, Jeon, Byeong-Hwa, Kim, Se-Hoon 대한생리학회 대한생리학회지 10 Pages
대한생리학회 대한생리학회지 1992, 제 26권 제 1호 5 45-54 (10 pages)
Effects of pH, PCO2, and adenosine on the vascular contractility were investigated in the pig coronary arteries. The helical strips of isolated coronary arteries were immersed in the HEPES or HCO3-/CO2-buffered Tyrode s solution equilibrated with 100% O2 or 95% O2-5% CO2 at 35℃. The contraction was recorded isometrically using a force transducer. The amplitudes of contraction induced by ACh, high K+, and electrical Held stimulation (EFS) were decreased by elevating extracellular pH (pHo) and... -
Mechanisms of Contraction Induced by Sodium Depletion in the Rabbit Renal Artery
Kim, Se-Hoon, Chang, Seok-Jong, 대한생리학회 대한생리학회지 12 Pages
대한생리학회 대한생리학회지 1991, 제 25권 제 2호 6 159-170 (12 pages)
In the rabbit renal artery, mechanisms of contraction by sodium depletion were investigated. The helical strips of isolated renal artery were immersed in the Tris-buffered salt solution. The contractions were recorded isometrically using a strain-gauge transducer. Na-free solution (Na was substituted by Li, choline or sucrose) produced contractions which were dependent on the nature of the Na substitutes. Na-free solution (choline) produced the contraction in ouabain-pretreated artery (Na loaded... -

membrane resistance was not changed. From the above results following conclusions could be made. 1) Serotonin inhibits spontaneous contractions of the circular muscle layer and it increases those of the longitudinal one, irrespective of the gastric region. 2) In the guinea-pig stomach there exists a serotoninergic facilitatory neuromodulation system which exerts its effect on cholinergically mediated contraction. 3) The excitation-contraction decoupling was observed in the effect of serotonin.
