Quercetin mainly exists in the skin of colored fruits and vegetables as one of flavonoids. Recent studies show that quercetin, like other flavonoids, has diverse pharmacological actions. However, relatively little is known about quercetin effects in the regulations of ligand-gated ion channels. In the previous reports, we have shown that quercetin regulates subsets of homomeric ligand-gated ion channels such as glycine, 5-HT3A and Ձ7 nicotinic acetylcholine receptors. In the present study,... -

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2009, Vol.13 No.1 7 39-48 (10 pages)
Gaegurin 4 (GGN4), an antimicrobial peptide isolated from a Korean frog, is five times more potent against Gram-positive than Gram-negative bacteria, but has little hemolytic activity. To understand the mechanism of such cell selectivity, we examined GGN4-induced K＋ efflux from target cells, and membrane conductances in planar lipid bilayers. The K＋ efflux from Gram-positive M. luteus (2.5</SUP>Ռg/ml) was faster and larger than that from Gram-negative E. coli (75Ռg/ml), while... -

종전에는 철탑을 올려서 문제점을 해소키 위하여 기존철탑을 완전히 해체하여 시공하는 방법을 택하여 왔으나 근래의 외국서적을 참조하면 기존탑을 완전히 해체하지 않고 기존탑에다 소요높이의 결구를 삽입함으로써 그 목적을 달성하고 있으며 어떤경우는 송전을 지속하는 상태에서 탑고을 올리고 있다. 본문에서는 이 공법도 겸하여 소개하고져 한다. 그리고 초고압철탑은 탑고가 높고 그 중량도 무거워져 종능전과 같은 본주의 gin pole을 이용한 철탑조립방식은 율이 올라가지 않고 또 위험성이 내포하고 있다. 따라서 본문은 또... -

정류방정식에서 정류주기중의 전류의 시간적변화와 정류주기종단에서 전류의 시간적 변화율의 값에 의하여 spark 발생여부를 판별하여 정류량부를 판별하였다. 본 논문은 상기한 방법과는 달리 정류의 기본방정식에서 정류곡선의 일반식을 구하고 정류곡선을 해석하여 정류양부를 판별하는 것이며, 정류주기중에 있는 단종선론의 coil저항과 연접한 극(pole)아래의 Brush에 의한 단각전류의 상호유도작용까지도 고려하였을때의 정류곡선의 일반식을 구하고 이를 해석하여 Langsdorf에 의하여 연구된 정류판별의 결과를 비교하여 정류판별에... -
