박세훈,지대림,성언기,김희선,송인환,박희영,김준수,이덕희,박대팔 대한마취과학회 2002 Korean Journal of Anesthesiology Vol.43 No.4

Background: Propofol has an antioxidant capacity and can be used for ischemia-reperfusion injury of the liver. However, the effects of propofol on the Kupffer cells have not been establisked. Methods: Kupffer cells were isolated and cultured from male Sprague-Dawley rats. The effects of propofol on the Kupffer cells were evaluated by a phagocytosis assay, TNF-α gene expression, and superoxide anion release after administering propofol in different concentrations on the cultured Kuprrer cells. Results: The latex bead phagocytosis by the Kupffer cells was suppressed when the Kupffer cells were exposed to propofol irrespective of concentrations. Higher propofol concentrations decreased the loss of Kupffer cells after latex bead phagocytosis. Propofol induced TNF-α mRNA expression in the Kupffer cells, but the mRNA expression level after 50㎍/ml of propofol decreased. The pattern of TNF-α mRNA expression induced by propofol was different to that induced by LPS: TNF-α mRNA was expressed continuously in the propofol-treated cells until 16 hours after exposure to propofol, whereas the level of TNF-α mRNA expression induced by LPS was evident after 2 hours and was not found thereafter. TNF-α production after propofol treatment was not higher than that of the control. Formazan presipitation did not show any qualitative differences between cells untreated or treated with propofol concentrations of 0.5, 5.0, and 50 ㎍/ml. Conclusions: These results showed that propofol might inhibit Kupffer cells. This suggests that propofol and be used for patients with ischemia-reperfusion injury of the liver.

Object : Schedule-induced polydipsia is considered as an animal model of obsessive-compulsive disorder inrats. The authors evaluated the chronic effects of fluoxetine and clomipramine as serotonergic antidepressants and haloperidol as dopaminergic antagonist on the schedule-induced polydipsia in rat.Methods : Spraque-Dawley rats weighing 200-250gm were individually housed, maintained and allowed free access to water for 1 week. And then the rats were placed on a restricted diet. To induce polydipsia, rats were placed in automatic cage where a pellet dispenser automatically dispensed 90mg pellets on a fixed-time 60 seconds(FT 60s) feeding schedule over 150-minute test session for a day. Water was available at all times during the feeding schedule in automatic cage. After 4 weeks of daily exposure to the FT 60s feeding schedule, experimental rats met a predetermined criterion for polydipsic behavior(greater than 3 times of water per session on average). 4 groups of rats were administered fluoxetine(5mg/kg/i.p.), clomipramine(5mg/kg/i.p.), haloperidol(0.1mg/kg/i.p.), vehicle(1cc/kg/i.p.) for 3 weeks. Rats were tested once a week to access schedule induced polydipsic behavior. The chronic effects of experimental drugs on schedule induced polydipsic behavior were analyzed with repeated analysis of variance and Scheffe test as a post-hoc comparison.In order to measure water consumption in non-polydipsic food-deprived rats, a separate group of rats(N=8) were individually housed and given a single bolus(14.5 gm) of food per day which maintained them at their average body weight.Results and Conclusion : The results were as follows ;1) After 4 weeks of daily feeding procedure with fixed time schedule for 60 seconds per day, the experimental group showed significant differences than the control in the amount of water consumption as compared with their baseline water intakes. At the same periods, there were no differences between the experimental group and the control in body weight. 2) The clomipramine treated group and the fluoxetine treated group showed significant decrease in the amount of water intake as compared with their baseline of polydipsic water intakes for 3 weeks of treatment. However, the haloperidol treated group and the vehicle control group showed no changes of amounts of water intake for 3 weeks of treatment as compared with their baseline of polydipsic water intakes. 3) At 2 weeks of drug treatment, clmipramine treated group(16.88±6.51ml) and the fluoxetine treated group(22.50±10.35ml) showed significantly lower amounts of water intake than the haloperidol treated group (41.25±7.06ml) or vehicle control group(37.50±12.54ml). And also the clomipramine treated group(13.75±5.18ml) and the fluoxetine treated group(18.75±3.54ml) showed significantly lower amounts of water intake than the haloperidol group(35.00±11.65ml) and the vehicle control(34.38±6.78ml) at 3 weeks of drug treatment. Above findings suggest that the fixed time feeding procedure for schedule-induced polydipsia as an animal model of obsessive compulsive disorder was effective to the evaluation of pharmacological challenge study. The author confirmed that schedule-induced polydipsia was successfully decreased for 3 weeks of administration of clomipramine and fluoxetine but there was no response to haloperidol.

2次元-表層密度流場의 解析에 있어서 境界層近似 適合性 檢討 : K-ε모델의 경우 with k-ε Model

金基興,咸契運,朴浚一 慶尙大學校生産技術硏究所 1995 生産技術硏究所論文集 Vol.11 No.-

Solving buoyant surface jet, the most important problem is the expression of turbulent transport. In this study, the compatibility of boundary layer approximation of k-ε model which has been applying to predict the turbulent transport in buoyant surface jet are considered. The results which has been comparing the computations of boundary layer approximation equations and full equation with experiments showed. As the result of this study, the hypothesis of boundary layer approximation does not express the transport by mean buoyancy in buoyant surface jet exactly, the hypothesis of boundary layer approximation is not valid for simulation of buoyant surface jet with k-ε model.

This research has been performed to evaluate the stoichiometric relationship between removed COD and nitrogen or phosphorus. A modified A²/O process, which was equipped with an external nitrification tank and a switching reactor, was operated with a capacity of 50㎥/d. From the results, it has been concluded that the stoichiometric values were varied by temperature condition or input COD loads. In case of denitirfication, the requirement g COD for removed nitrate nitrogen ranged 0.13 to 10.5g, and the compensation coefficient of temperature was evaluated as 1.028. For phosphorus removal, the required COD was about 7.5gCOD_(consumed)/gP_(released) and 0.54gPHACOD_(storage)/gP_(uptake). During rainy season, as it appeared a lower organic substrate loads, the PHA(Poly Hydroxy Alkanoate) contents of biomass was reduced. From the relationship between influent BOD, and the sum of removed TN and TP, the ratio for rainy and winter season was about 4.8 and 5.8g BOD/g (TN+TP) each others. Therefor, the substrat ratios for nitrogen and phosphorus removal appeared to be affected by temperature and influent organic substrate loads.

The effect of dehydrating agent in DMC(dimethyl carbonate) synthesis from methanol and carbon dioxide over Ce_(0.8)Zr_(0.2)O₂ catalyst was studied in this work. Ce_(0.8)Zr_(0.2)O₂ catalyst having the best activity among Ce_(1-x)Zr_(x)O₂ catalysts was selected. We could supposed that the addition of dehydrating agents improved the DMC yield by H₂O elimination. When the dehydrating agents such as Na_(2)SO₄ or K₂SO₄ was added into the synthesis of DMC, the formation amount of DMC increased to about 0.8∼0.9 mmol through the elimination of formed H₂O as by-product.
