Fluorescence polarization of 1,6-diphenyl-1,3,5-hexatriene (DPH) was used to evaluate the effects of dopamine·HCl on the range of the rotatioanl mobility of bulk bilayer structure of the synaptosomal plasma membrane vesicles (SPMV) isolated from whole bovine brain. In a dose-dependent manner, dopamine decreased the anisotropy (γ), limiting anisotropy (γ∞) and order parameter (S) of DPH in the membranes. These indicate that dopamine increased the rotational mobility of the probe in the...

In order to provide a basis for studying the molecular mechanism of pharmacological action of local anesthetics and to develop a fluorescence spectroscopic method which can detect the microviscosity of native and model membranes using intramolecular excimerization of 1,3-di(l-pyrenyl)propane (Py-3-Py), we examined the effect of lidocaine·HCl on the microviscosity of model membranes of phosphatidylcholine fraction extracted from synaptosomal plasma membrane vesicles (SPMVPC). The excimer to...

Using fluorescence polarization of 12-(9-anthroyloxy)stearic acid (12-AS) and 2-(9-anthroyloxy)stearic acid (2-AS), we evaluated the differential effects of local anesthetics on differential rotational rate between the surface (in carbon number 2 and its surroundings including the head group) and the hydrocarbon interior (in carbon number 12 and its surroundings) of the outer monolayer of the total lipid fraction liposome extracted from synaptosomal plasma membrane vesicles. The anisotropy (r)...

This study was undertaken to examine the effect of ethanol on Na⁢-dependent phosphate (Na⁢-Pi) uptake in opossum kidney (OK) cells, an established renal proximal tubular cell line. Ethanol inhibited Na⁢-dependent component of phosphate uptake in a dose-dependent manner with I50 of 8.4%, but it did not affect Na⁢-independent component. Similarly, ethanol inhibited Na⁢-dependent uptakes of glucose and amino acids (AIB, glycine, alanine, and leucine). Microsomal...

medium, but it showed no apparent effect on the Pi-protectable PFA binding. These results indicate that an interaction of renal BBM with free Cd induces a reduction in Na⁢-Pi cotransport activity without altering the carrier density in the membrane. This, in turn, suggest that the suppression of phosphate transport capacity (Vmax) observed in Cd-treated renal BBM is due to a reduction in Na⁢-Pi translocation by existing carriers, possibly by Cd-induced fall in membrane fluidity.

This study was undertaken to examine the effect of ethanol on Na⁢-dependent transport systems (glucose, phosphate, and dicarboxylate) in renal brush-border membrane vesicles (BBMV). Ethanol inhibited Na⁢- dependent uptakes of glucose, phosphate, and succinate in a dose-dependent manner, but not the uptakes of Na⁢-independent. The H⁢/TEA antiport was reduced by 8% ethanol. Kinetic analysis showed that ethanol caused a decrease in Vmax of three transport systems, leaving...

A reversed-phase high-performance liquid chromatogrphy (RP-HPLC) has been developed to analyze the metabolites of arachidonic acid based on the specificities of ultraviolet absorption of these various metabolites and is sensitive to the nanogram level. This procedure makes it possible to extract complex mixtures of eicosanoids efficiently with a single step and to analyze them simultaneously by RP-HPLC from biological samples using octadesylsilyl silica extraction column and PGB2 as an internal...

addition, similar insulation distance (7∼9 Å) of channel mouth from the bilayer surface charge was predicted by a 3-barrier-2-site model of energy profile for the permeation of K⁢ ions. In conclusion, despite the differences in structure and fluidity of phospholipids in bilayers, the activities of maxi K channels in two charged membranes composed of PS or PI were strikingly similar and larger than those in bilayers of PE. These results suggest that the enhancement of conductance and Po o...

목 적： 혈청 콜레스테롤 농도와 자살 등의 공격행동간의 연관성에 관한 여러 연구가 있었으나 일치된 결과를 보이고 있지 못하다. 이에 저자들은 다양한 진단의 정신과 입원 환자들 중 공격행동을 보인 환자의 콜레 스테롤 농도를 정상 한국 성인에서의 혈청 총 콜레스테롤의 성별, 연령별 평균 및 표준편차와 percentile 분포에 맞추어 공격행동 및 자살시도와 혈청 콜레스테롤 농도간의 연관성을 알아보기 위하여 본 연구를 시행하였다. 방 법： 본 연구는 1994년 1월 1일부터 1995년 6월 31일까지 18개월간 가톨릭대학교...

연구목적： 혈청 콜레스테롤 농도가 저하된 경우에 충동성이 증가한다는 많은 연구가 이루어져왔으며, 최근에는 콜레스테 롤 농도와 독립적으로 혈청 중성지방이 충동성 및 적대적 행동, 우울증과 관련된다는 연구결과가 보고되고 있다. 본 연구에서는 충동성이 높은 시기인 청소년을 대상으로 혈청 콜레스테롤과 충동성의 관계, 혈청 중성지방과 충동성의 관계를 조사해보았다. 방 법： 경상남도 한 군지역 내 고등학교 1학년생 전체 518명을 대상으로 2000년 5월에서 6월 사이에 실시하였으며, 이 가운데 혈청 지질에 영향을 줄 수 있는...
