The amygdala is known as a site for inducing analgesia, but its action on the trigeminal nucleus has not been known well. Little information is available on the effect of dynorphin on NMDA receptor-mediated electrophysiological events in the trigeminal nucleus. The purpose of this study was to investigate the changes in the single neuron spikes at the trigeminal nucleus caused by the amygdala and the action of dynorphin on the trigeminal nucleus. In the present study, extracellular single unit...

This study was undertaken to investigate an involvement of nitroxergic innervation in gastric smooth muscle of rat. Isometric tension study, the measurement of single cell length, NADPH diaphorase stain of smooth muscle layers and neuronal nitric oxide synthase (nNOS) western blotting were performed. Sodium nitroprusside (SNP), a nitric oxide donor, relaxed the muscle strips precontracted by acetylcholine (ACh) in a concentration-dependent manner. Pretreatment of L-arginine decreased the...

To investigate interaction of angiotensin converting enzyme (ACE) inhibitor with local tissue renin- angiotensin system (RAS), changes in gene expression of the RAS components in various tissues in response to chronic administration of an ACE inhibitor, enalapril, were examined in Sprague-Dawley male rats. Enalapril was administered in their drinking water (3∼4 mg/day) over 8 wk. Plasma and renal ACE activity increased significantly after 4 and 8 wk of enalapril treatment. Renin levels of the...

Cromakalim (BRL 34915), known as an airway smooth muscle relaxant, inhibited the releases of mediators in the antigen-induced mast cell activation. It has been suggested that cromakalim, in part, inhibited mediator releases by inhibiting the initial increase of 1,2-diacylglycerol (DAG) produced by the activation of the other phospholipase system which is different from phosphatidylcholine-phospholipase D pathway. The aim of this study is to further examine the inhibitory mechanism of cromakalim...

We previously reported that some components of ginsenosides decreased mediator releases evoked by the activation of mast cells with specific antigen-antibody reactions. This study aimed to assess the effects of ginsenosides (Rb2, Re) on the mechanism of histamine release in the mast cell activation. We partially purified guinea pig lung mast cells by using enzyme digestion, the rough and the discontinuous percoll density gradient method. Mast cells were sensitized with IgG1 and challenged with...

플라즈마 리플로우 솔더링에서 솔더볼의 접합성을 향상시키기 위해 UBM(Under Bump Metallization)을 Ar-10vol%$H_2$플라즈마로 클리닝하는 방법을 연구하였다. UBM층은 Si 웨이퍼 위에 Au(두께; 20 nm)/ Cu(4 $mu extrm{m}$)/ Ni(4 $mu extrm{m}$)/ Al(0.4 $mu extrm{m}$)을 웨이퍼 측으로 차례대로 증착하였다. 무연 솔더로는Sn-3.5wt%Ag, Sn-3.5wt%Ag-0.7wt%Cu를 사용하였고 Sn-37wt%Pb를 비교 솔더로 사용하였다. 지름이500 $mu extrm{m}$인 솔더 볼을 플라즈마 클리닝 처리를 한 UBM과 처리하지 않은 UBM위에 놓고,...

SnAg, SnAgCu, SnCu 무연솔더합금을 주조 상태에서 냉간압연한 후 열적으로 안정화한 시편 (TS)과, 실제 솔더 범프와 유사한 미세구조의 수냉에 급속 냉각(WQ)된 시편 두가지를 $100^{circ}C$에서 크리프 실험을 행하였다. 급속냉각한 시편의 냉각속도는 140-150 K/sec로 primary $eta-Sn$ 크기가 TS 시편보다 5∼10배 정도 작았으며, 기지내 primary $eta-Sn$이 차지하는 분율은 증가하였다. 반면에 공정상 내의 $Ag_3Sn$상의 크기는 더 작아졌다. 크리프 실험 결과 WQ 시편의 최소크리프 변형율 속도(${beta}_{min}$)가 TS 보다 약...

The element carbon has been used as a source of energy for the past few hundred years, and now in this era of technology, carbon has played a significant and very prominent role in almost all fields of science and technology. So as an honour to this marvellous element, we humans should know about its various forms of existence. In this review article, we shed light on all possible carbon-allotropes; similarities in their synthesis techniques and the starting materials; their wide range of...

Materials with appropriate surface roughness and low surface energy can form superhydrophobic surfaces, displaying water contact angles greater than 150°. Superhydrophobic carbon-based materials are particularly interesting due to their exceptional physicochemical properties. This review discusses the various techniques used to produce superhydrophobic carbon-based materials such as carbon fibers, carbon nanotubes, graphene, amorphous carbons, etc. Recent advances in emerging fields such as...
