To study the protective effects of antioxidants on the radiation damages of the cells, vascular smooth muscle cells (VSMC) from thoracic aorta of Sprague-Dawley rats were cultured and irradiated with gamma-ray. Cell viability was measured by direct cell counting and MTT assay, and flow cytometry was performed to measure fractional distributions of the cells. Gamma-ray irradiation inhibited cell proliferations accompanied with decreased G1 phase and increased S- and G2/M phases, and the maximum...

Adenosine has been reported to provide cytoprotection in the central nervous systems as well as myocardium by activating cell surface adenosine receptors. However, the exact target and mechanism of its action still remain controversial. The present study was performed to examine whether adenosine has a protective effect against Aβ-induced injury in neuroglial cells. The astrocyte-derived human neuroglioma cell line, A172 cells, and Aβ25∼35 were employed to produce an experimental Aβ-induced...

It is imperative to analyse brain injuries directly in real time, so as to find effective therapeutic compounds to protect brain injuries by stress. We established a system which could elucidate the real time Ca2⁢ dynamics in an organotypic cultured hippocampal slice by the insults of artificial stress hormone, dexamethasone. The real time Ca2⁢ dynamics could continuously be detected in cornus ammonis 3 (CA3) of the organotypic hippocampus for 8 hours under confocal microscopy. When...

AM fluorescent dyes, respectively, by Laser Scanning Confocal Microscopy (LSCM). Furthermore, the role of sarcolemmal Na⁢/Ca2⁢ exchange (NCX) in cytosolic Ca2⁢ efflux was studied in KB-R7943 and Na⁢-free normal Tyrode's solution (143 mM LiCl ). When DNP was applied to cells loaded with Fluo-4 AM, Fluo-4 AM fluorescence intensity initially increased by 70⁑10% within 70⁑10 s, and later by 400⁑200% at 850⁑46 s. Fluorescence intensity of both Rhod-2 AM...

To investigate the effect of fluoxetine, one of selective serotonin reuptake inhibitors (SSRIs), on the immune system, human peripheral blood mononuclear cells (PBMC) were treated with fluoxetine (10⁣7 M) for 24 h, and immune-related genes were analyzed by cDNA microarray. Expression of the immune- related genes such as CD107b (LAMP-2), CD47 receptor (thrombospondin receptor), CD5 antigen-like (scavenger receptor cysteine rich family), copine III (CPNE3), interleukin (IL)-18...

Previous studies have suggested that brain stem noradrenergic inputs differentially modulate neurons in the paraventricular nucleus (PVN). Here, we compared the effects of norepinephrine (NE) on spontaneous GABAergic inhibitory postsynaptic currents (sIPSCs) in identified PVN neurons using slice patch technique. In 17 of 18 type I neurons, NE (30∼100μM) reversibly decreased sIPSC frequency to 41⁑7% of the baseline value (4.4⁑0.8 Hz, p＜0.001). This effect was blocked by yohimbine...

of gap junction permeable dyes into an endothelial cell results in a distribution of the dye to surrounding cells including smooth muscle cells. These observations allow the speculation that myoendothelial gap junctions may have a functional significance. Simultaneous measurement of the electrical responses in both endothelial and smooth muscle cells using the double patch clamp method demonstrates that these two cell types are indeed electrically coupled, indicating that they behave as a...

본 실험에서는 PC12 세포를 신경세포 모델로 형광물질인 fura-2 및 bisoxonol을 이용하여 세포내 유리 칼슘이온 농도 및 막전압을 각각 측정하여 화학구조가 서로 다른 몇몇 항우울제가 막전압 의존성 칼슘통로 의 활성화 및 ATP를 통한 수용체 의존성 칼슘통로의 활성화에 미치는 영향을 관찰하여 아래와 같은 결과를 얻었다. 1) 선택적 serotonin 재흡수 억제제의 하나인 sertraline은 60mM KCl 자극 및 100μM ATP 자극에 의 한 [Ca2＋]i 의 증가를 억제하였으며 이때 IC 50 값은 각각 2.5μM과 5.3μM이었다. 2) 막전압 의존성...

In the present study, we observed change in intracellular Ca2+([Ca2+]i) as measured with the fluorescent Ca2+-indicator fura-2 in association with force development of the rat basilar arteries during activation byK+ depolarizing solution and U46619, a thromboxane analogue, in the absence and the presence of calcitonin-gent related peptide (CGRP). CGRP (30 and 100 nM) caused a concentration-dependent inhibition of U46619-induced contraction with decrease in [Ca2+]i, whereas it did not exert any...

가토흉부대동백근에서 MeB와 gentian violet는 용량-의존성 수축반응을 일으켰으나 evans blue와 eosine yellowish는 전혀 수축반응을 일으키지 못하였다. MeB는 돼지 장간막 동맥에서도 용량-의존성 수축반응을 일으켰다. 양표본에서 MeB 10-4 M의 단회투여는 수축반응에 이어 이완반응이 나타나는 양상성 반응을 일으켰으나, tyramine은 지속적인 수축반응을 일으켰다. Tyramine의 수축반응은 반복적이었으나 MeB의 그것은 일차 수축반응 후 3 ~ 5시간 후까지도 반복되지 않았다. Tyramine 10-4 M의 최대 수축반응 상태에서 MeB 10-4...
