Vascular diseases are significant complications of diabetes mellitus (DM), and the endothelial cells may play a pivotal role in the development of vascular disease in DM. Endothelin-1 (ET-1) released from endothelium is a potent vasoconstrictor peptide and circulating level of ET-1 is increased in a variety of disease states. The purpose of this study was to determine the changes of responsiveness to ET-1 in DM, and we experimented on the changes in the ET-1-induced contraction, levels of... -

To investigate the properties of cromakalim-opened K+ channels in aorta of spontaneously hypertensive rats (SHR), the effect of cromakalim on tension was compared in endothelium-rubbed aortic rings from SHR and normotensive Wistar-Kyoto rats (WKY). 1. Cromakalim relaxed the aortic ring contracted by 10-7 M norepinephrine (NE) dose-dependently, and this relaxant response to cromakalim was blocked by 10-5 M glybenclamide. 2. Cromakalim also relaxed the contraction induced by high K+-solution or... -

식물체에서 수액상승의 원리는 근압설(양압)과 응집력설(음압)으로 설명되고 있다. 그러나 증산에 의 한 물기둥의 상승인 응집력-장력 가설에서 색전 현상을 회복하는 설명이 부족하였다. 오랫동안 단 순한 물리적인 현상으로 모세관 이론에 의해 표면장력과 증산으로 인한 곡면이 충분히 물기둥을 다 시 연결시킬 수 있다고 보았으나 이제는 새로운 관점으로 도관 유조직의 도움을 받아서 당을 분비 함으로 삼투적인 회복이 일어난다고 본다. 따라서 도관은 더 이상 죽은 조직이 아니라 살아 있는 조직으로 체관과의 상호작용을 하여... -

In this essay, the author provides a working definition of philosophy from a cultural point of view, and argues the need for mathematics educators to develop their philosophy of mathematics teaching and learning or, to speak more broadly, their philosophy of education. He then historically situates three scholars?John Dewey, Paulo Freire, and Michel Foucault?who have been instrumental in the formulation of his philosophy of education. Next, he shares how the philosophies of these three scholars...
