흰쥐 뇌내(腦內)의 무수카린성 콜린 수용체의 이질성(異質性)
이종화(Jong-Hwa Lee), Esam E. EI-Fakahany 대한약리학회 대한약리학잡지 12 Pages

일정기간 규정사료를 사육하였고, 사용한 Radioactive ligands는 (3H) QNB와 (3H) NMS였으며 그외에 다른 수종의 길항제 또는 효능제와의 치환작용을 brain homogenates와 intact brain cell aggregates에서 관찰하여 다음과 같은 결과를 얻었다. 1. (3H) QNB와 (3H) NMS는 모두 질량작용의 법칙에 비례하여 수용체와의 결합에서 높은 친화력과 포화를 보였으며 또한 높은 결합 능력을 나타내었다. 더욱이 homogenates 제제와 intact cell aggregates제제에서의 결과 사이에는 유사한 점이 많았다. 2. Homogenates제제를 사용한 실험에서,... -
Oxygen/Glucose Deprivation and Reperfusion Cause Modifications of Postsynaptic Morphology and Activity in the CA3 Area of Organotypic Hippocampal Slice Cultures

Brain ischemia leads to overstimulation of N-methyl-D-aspartate (NMDA) receptors, referred as excitotoxicity, which mediates neuronal cell death. However, less attention has been paid to changes in synaptic activity and morphology that could have an important impact on cell function and survival following ischemic insult. In this study, we investigated the effects of reperfusion after oxygen/glucose deprivation (OGD) not only upon neuronal cell death, but also on ultrastructural and biochemical... -
Proton Transport in Human Placental Microvillous Membrane Vesicles
Ri, Ok-Kyung, Jung, Jin-Sup, Kim, Won-Whe, Lee, Sang-Ho 대한생리학회 대한생리학회지 12 Pages

The change of the acridine orange absorbance was used to monitor the formation and/or dissipation of a pH gradient in microvillous membrane vesicles (MVV) isolated from human term placenta. Under Na+ efflux conditions, an acidification of the intravesicular space occured and it was completely inhibited by 0.1 mM amiloride. Under K+ efflux conditions, an acidification of the intravesicular space occured and it was potentiated by valinomycin or FCCP. An inwardly directed chloride gradient also... -
