gap junctions. Although cadmium (Cd) is known to induce apoptosis in organs and tissues, the mechanisms that underlie gap junction activity in Cd-induced apoptosis in BRL 3A rat liver cells has yet to be established. In this study, we showed that Cd treatment decreased the cell index (a measure of cellular electrical impedance) in BRL 3A cells. Mechanistically, we found that Cd exposure decreased expression of connexin 43 (Cx43), increased expression of p-Cx43 and elevated intracellular free Ca... -
Gap Junction Contributions to the Goldfish Electroretinogram at the Photopic Illumination Level

photopic illumination level. Several agents were used to affect gap junctions, such as dopamine D1 and D2 receptor agonists and antagonists, a nitric oxide (NO) donor, a nitric oxide synthase (NOS) inhibitor, the gap junction blocker meclofenamic acid (MFA), and mixtures of these agents. The ERG b-waves, which were enhanced by MFA, sodium nitroprusside (SNP), SKF 38393, and sulpiride, remained following application of a further injection of a mixture with MFA. The ERG b-waves decreased following... -

악안면 영역에 동통이 가하여지면 회피반사의 일종인 개구반사가 유발되며, 개구반사의 크기는 뇌간의 중추에 전달된 동통의 크기에 비례한다. 따라서 동통의 정도를 악이복근의 근전도를 이용하여 정량화 할 수 있고 동통의 지표로 이용할 수 있다. 본 실험은 악안면동통에 의하여 유발된 개구반사의 크기가 침점(족삼리) 전기자극으로 감소되는지와 이러한 전기침의 효과가 나타나는데 opioid 물질이 관여하는지에 대하여 연구하고자 하였다. 8주 이상, 150g이상의 Sprague-Dawley계 쥐 34 마리를 암수 구별없이 이용하여 실험하였다.... -

In this paper, a practical curriculum for using cloud software (SW) is proposed that can be applied as a subject for strengthening the untact education capability of field teachers. For untact education, teachers require content creation and online collaboration skills. Content creation forms are divided into real-time and video contents. Cloud-based SW can be used for online collaboration education. Currently, cloud-based Google and Chrome SW can be used to create real-time and video contents.... -

Here, percutaneous spinal cord injury (SCI) methods using a balloon catheter in adult rats are described. A balloon catheter was inserted into the epidural space through the lumbosacral junction and then inflated between T9-T10 for 10min under fluoroscopic guidance. Animals were divided into three groups with respect to inflation volume: 20 μL (n = 18), 50 μL (n = 18) and control (Fogarty catheter inserted but not inflated; n = 10). Neurological assessments were then made based on BBB score,... -

To investigate the effects of gossypol acetic acid (GA) on proliferation and apoptosis of the macrophage cell line RAW264.7 and further understand the possible underlying mechanism responsible for GA-induced cell apoptosis, RAW264.7 cells were treated with GA (25∼35 μmol/L) for 24 h and the cytotoxicity was determined by MTT assay, while apoptotic cells were identified by TUNEL assay, acridine orange/ethidium bromide staining and flow cytometry. Moreover, mitochondrial membrane potential... -

Three-dimensional finite element model was made from adult skull to find desirable direction of retraction force to treat skeletal class II malocclusion. The retraction force of 400g was applied to the first molar. The direction of the force application was 23° downward, parallel, 23° upward and 45` upward to the occlusal plane. The stress distribution and the displacement within the maxilla were analyzed by three-dimensional finite element method. The findings obtained were as follows: 1.... -

The aging process induces a plethora of changes in the body including alterations in hormonal regulation and metabolism in various organs including the heart. Aging is associated with marked increase in the vulnerability of the heart to ischemia-reperfusion injury. Furthermore, it significantly hampers the development of adaptive response to various forms of conditioning stimuli (pre/post/remote conditioning). Aging significantly impairs the activation of signaling pathways that mediate... -

Remote ischemic preconditioning (RIPC) is an intrinsic phenomenon whereby 3~4 consecutive ischemia-reperfusion cycles to a remote tissue (noncardiac) increases the tolerance of the myocardium to sustained ischemiareperfusion induced injury. Remote ischemic preconditioning induces the local release of chemical mediators which activate the sensory nerve endings to convey signals to the brain. The latter consequently stimulates the efferent nerve endings innervating the myocardium to induce... -

Myometrial relaxation of mouse via expression of two‐pore domain acid sensitive (TASK) channels was studied. In our previous report, we suggested that two‐pore domain acid‐sensing K+ channels (TASK-2) might be one of the candidates for the regulation of uterine circular smooth muscles in mice. In this study, we tried to show the mechanisms of relaxation via TASK-2 channels in marine myometrium. Isometric contraction measurements and patch clamp technique were used to verify... -

Connexins (Cx) are membrane proteins and monomers for forming gap junction (GJ) channels. Cx46 and Cx50 are also known to function as conductive hemichannels. As part of an ongoing effort to find GJ-specific blocker(s), endocrine disruptors were used to examine their effect on Cx46 hemichannels expressed in Xenopus oocytes. Voltage-dependent gating of Cx46 hemichannels was characterized by slowly activating outward currents and relatively fast inward tail currents. Bisphenol A (BPA, 10 nM)... -

Lubiprostone is a chloride (Cl−) channel activator derived from prostaglandin E1 and used for managing constipation. In addition, lubiprostone affects the activity of gastrointestinal smooth muscles. Interstitial cells of Cajal (ICCs) are pacemaker cells that generate slow-wave activity in smooth muscles. We studied the effects of lubiprostone on the pacemaker potentials of colonic ICCs. We used the whole-cell patch-clamp technique to determine the pacemaker activity in cultured colonic... -
Role of T-type Ca2＋ Channels in the Spontaneous Phasic Contraction of Pregnant Rat Uterine Smooth Muscle

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2009, Vol.13 No.3 15 241-249 (9 pages)
Although extracellular Ca2＋ entry through the voltage-dependent Ca2＋ channels plays an important role in the spontaneous phasic contractions of the pregnant rat myometrium, the role of the T-type Ca2＋ channels has yet to be fully identified. The aim of this study was to investigate the role of the T-type Ca2＋ channel in the spontaneous phasic contractions of the rat myometrium. Spontaneous phasic contractions and [Ca2＋]i were measured simultaneously in the longitudinal strips of female...
