한국종교교육학회 종교교육학연구 2004, 제 18권 3 59-78 (20 pages)
John Dewey s lifelong attention to religious themes found expression in his 1934 book A Common Faith. Among the pragmatic themes he developed there are that: a) human experience left to develop without outside interference is capable of generating ideals and values, and b) beliefs that are true, including religious beliefs, are so only when they have been tested in the laboratory of experience. Rather than choose among the world s religions, Dewey emphasized the religious quality that... -

Adhesion events of monocytes represent an important step in inflammatory responses induced by chemokines. The β1-integrin CD29 is a major adhesion molecule regulating leukocyte migration and extravasation. Although several adhesion molecules have been known as regulators of CD29, the molecular interactions between CD29 and its regulatory adhesion molecules (such as CD98 and CD147) have not been fully elucidated. Therefore, in this study, we examined whether these molecules are functionally,... -
A Novel Nicotinamide Adenine Dinucleotide Correction Method for Mitochondrial Ca2+ Measurement with FURA-2-FF in Single Permeabilized Ventricular Myocytes of Rat
JeongHoonLee, JeongMiHa, ChaeHunLeem 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 10 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2015, Vol.19 No.4 10 373-382 (10 pages)
Fura-2 analogs are ratiometric fluoroprobes that are widely used for the quantitative measurement of [Ca2+]. However, the dye usage is intrinsically limited, as the dyes require ultraviolet (UV) excitation, which can also generate great interference, mainly from nicotinamide adenine dinucleotide (NADH) autofluorescence. Specifically, this limitation causes serious problems for the quantitative measurement of mitochondrial [Ca2+], as no available ratiometric dyes are excited in the visible range.... -

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2012, Vol.16 No.3 3 167-174 (8 pages)
Natural killer (NK) cells provide one of the initial barriers of cellular host defense against pathogens, in particular intracellular pathogens. Because bone marrow-derived hematopoietic stem cells (HSCs), lymphoid protenitors, can give rise to NK cells, NK ontogeny has been considered to be exclusively lymphoid. Here, we show that porcine c-kit＋ bone marrow cells (c-kit＋ BM cells) develop into NK cells in vitro in the presence of various cytokines [interleukin (IL)-2, IL-7, IL-15, IL-21, stem... -
Requirement of Pretone by Thromboxane A2 for Hypoxic Pulmonary Vasoconstriction in Precision-cut Lung Slices of Rat
SuJungPark, HaeYoungYoo, HyeJinKim, , , JinKyoungKim, Yin-HuaZhang, SungJoonKim, 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 6 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2012, Vol.16 No.1 9 59-64 (6 pages)
Hypoxic pulmonary vasoconstriction (HPV) is physiologically important response for preventing mismatching between ventilation and perfusion in lungs. The HPV of isolated pulmonary arteries (HPV-PA) usually require a partial pretone by thromboxane agonist (U46619). Because the HPV of ventilated/perfused lungs (HPV-lung) can be triggered without pretone conditioning, we suspected that a putative tissue factor might be responsible for the pretone of HPV. Here we investigated whether HPV can be also... -

from 0 to 11.8 and 28.2 mV, respectively. The relative permeability of the cytolysin pores to anions measured at 40 mV was Cl = NO2 ≥ Br = I ＞ SCN ＞ acetate ＞ isethionate ＞ ascorbic acid ＞ EDTA2, in descending order. The cytolysin-induced pore current was blocked by Cl channel blockers or nucleotides. These results indicate that V. vulnificus cytolysin forms anion-selective pores in CPAE cells. -
Intrinsic Gating in Inward Rectifier Potassium Channels (Kir2.1) with Low Polyamine Affinity Generated by Site Directed Mutagenesis
ISo, , IAshmole, HSoh, CSPark, PJSpencer, MLeyl, PRStanfield, 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 12 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2003, Vol.7 No.3 3 131-142 (12 pages)
We have studied mutant forms of Kir2.1 in which an aspartate residue (D172), important for gating by intracellular polyamines, is replaced by one of three basic residues (Arg, Lys or His). Such channels are highly selective for K+, but show inward rectification that is a shallow function of voltage compared with that found in wild type. This inward rectification occurs with a reduced affinity for spermine and persists in the absence of polyamines. Though the unitary current-voltage relation... -

According to the traditional receptor model, competitive antagonists share with agonists the ability to bind to a common site on receptors, but they are different from agonist in that they cannot trigger the biological response-i.e., they lack intrinsic efficacy. Recent findings extend the model by indicating that not all antagonists display an intrinsic efficacy of zero but that some display inverse agonism . In the present study we studied the inverse agonism at A1 adenosine receptors in... -

K+통로는 기도 평활근 세포에 존재하며 이들 통로가 활성화되면 평활근의 과분극의 결과 이완작용이 나타난다. K+통로의 이런 효과는 과민반응과 천식 치료에 응용될 수 있으므로 우리는 K+통로 개방제인 cromakalim (BRL34915, CK)이 IgG1 항체로 감작시킨 기도 및 폐조직으로 부터 유리되는 매개체 유리에 미치는 영향을 조사하였다. 피동적으로 감작된 두 조직은 2 × 10-6 M의 CK로 30분동안 superfusion시킨 후 CK와 항원 (Ox-HSA) 0.1 mg/ml로 자극하였다. 또한 비만세포를 이용하여 CK의 효과를 조사하였다. 해명 폐조직... -

사람의 혈액으로부터 Elastase를 분리하는 새로운 방법을 개발하여 순도 높은 효소를 얻고 이 효소에 의하여 발생되어지는 질병의 예방과 치료에 응용하기 위하여 이 효소의 근본적인 성질규명을 시도하였다. 정제 방법으로는 Sephodex G-75를 이용한 1회의 액체 크로마토그라피와 HPLC을 이용한 2회의 코마토그라피를 거치는 2단계 방법을 사용하였다. 이때 얻어진 효소는 분자량이 26,000 ~ 29,700 사이에 있는 3개의 다른 분자량을 가진 물질로 확인되었으며, 항체 반응에서 사람의 결구내 Elastase의 특성을 나타내었다. 함유하고... -

국소마취제의 약리학적 작용기전을 탐구키 위하여 소의 신선한 대뇌피질로부터 synaptosomal plasma membrane vesicles(SPMV)를 분리한 후 그 소수성 중심부의 microviscosity에 미치는 국소마취제의 영향을 pyrene 형광 probe법으로 측정한 결과 lidocaine HCI과 procaine HCI이 microviscosity를 낮춘다는 것을 알았고 그 정도는 procaine HCI에 비하여 tidocaine.HCI이 더욱 컸다. 또 국소마취 제 가 dimyristoylphosphatidylcholine (DMPC) multilamellar liposomes의 상전 이온도를 낮추며 cooperative unit크기를 감소시킨다는 것도... -
Calcium Current in the Unfertilized Egg of the Hamster

iCa2+ in the unfertilized hamster eggs remains unclear. Analysis from steady-state inactivation activation curves reveals that only a small amount of this current will pass in the voltage range (-70 ~ -30 mV) which partially overlaps with the resting membrane potential. This current has the property that it can be easily activated by a weak depolarization, thus it may trigger a certain kind of a intracellular event following fertilization which may cause oscillations in the membrane potential.
