          김희철,김정호,김영일,Kim, Hee-Chul,Kim, Jeong-Ho,Kim, Young-Il 대한침구의학회 2008 대한침구의학회지 Vol.25 No.4

          Objectives : The aim of this study is comparing the improvement of Bell's palsy and Ramsay hunt syndrome according to treatment duration. Methods : The 11cases diagnosed as Ramsay hunt syndrome and 30cases of Bell's palsy who visited Cheong-ju Oriental Medical hospital from February 2006 to June 2008 were evaluated. We used Yanagihara's unweighted Grading System to confirm the improvement. Results : In the analysis of cause, except the "none", the most common cause was "Overwork" in both two group. After 5-day treatment the score was getting worse but after 10-day treatment score was improved in both group. The improvement of Bell's palsy group was better than that of Ramsay hunt syndrome group after 5-day and 10-day treatment, but there was no significance. Conclusions : In comparison of Yanagihara's unweighted grading score checked before treatment, after 5-day, 10-day and 15-day treatment between Bell's palsy and Ramsay hunt sundrome, there was no statistical significant difference.

        • 몬테카를로 시뮬레이션을 이용한 다면 공간의 조도계산

          김희철,김훈,지철근,Kim, Hee-Chul,Chee, Chul-Kon,Kim, Hoon 한국조명전기설비학회 1993 조명.전기설비 Vol.7 No.6

          In order to improve complicated construction and complex control which are didvantage of optimal PWM technique aimed at harmonic elimination method, this paper presented MRA(Mode1 Reference Adaptive) PWM technique that gating signal of inverter is generated by comparing the reference signal with the induced feedback signal at the reference model of load. Design of controller is composed of microprocessor and analog circuit. MRA PWM technique used in the paper is able to compensate the degradation of voltage efficiency to be generated by the ratio of the output voltage to the DC supply voltage being low for using conventional sinusoidal PWM technique. When the trapezoidal signal is employed as the reference signal. the low order harmonics of line current can be reduced and the switching pattern is made by on-line computation using comparatively simple numerical analysis. 본 논문에서는 몬테카를로 시뮬레이션을 이용하여 복잡한 다면 실내공간에서 조도분포를 예측하는 방법을 제안하였다. 광원으로부터 방사하는 빛을 배광분포에 따른 가중치를 가지고 진행하는 입자로 가정하였으며 광원에서 방출된 빛의 경로를 추적하여 반사면과의 교점을 구한다. 그리고 반사면의 반사율을 고려하여 이자가 반사 또는 흡수될 것인가를 판단하고 그 입자가 흡수될 때까지 입자의 진행을 반복한다. 무수히 많은 입자에 대해 위와 같은 과정을 반복하면 실내면의 조도분포를 얻을 수 있다. 보다 세밀한 측정을 위하여 각 실내면은 매우 작은 미소면적으로 분할하였다. 그리고, 실제공간에서도 응용될 수 있도록 실제의 공간과 유사한 다면 실내공간에 대해서 시뮬레이션을 하였으며, 조도분포에 따라 이차원의 등조도 곡선과 삼차원의 조도분포곡선을 그렸다. 실제로 모델공간을 제작하여 조도를 측정해 본 결과, 실험치와 계산치의 오차가 평균 2.3% 이내로 되었다.

          It has been reported that Bopheyangyoungjeon(BYJ) has an effect on deficiency asthma(喘虛) clinically. The aim of this study was to determine an appropriate dosage of BYJ to treat asthma. In order to study the effects of orally administered BYJ on allergic asthma, mice were pretreated with three oral doses of the herbal solution of BYJ before antigen sensitization. 2 days later Mice were actively sensitized with a subcutaneous injection of ovalbumin and 13 day later ovalbumin aerosols were used to provoke asthmatic reaction. Serum level of IgE, IL-4, WBC, RBC, HGB, cell numbers in bronchoalveolar lavage fluid(BALF), and in vitro isometric contractile responses of the isolated tracheal smooth muscle(TSM) to acetylcholine(ACh, 0.1-1000uM), KCl were measured. The results were as follows ; 1. Contractile responses of TSM to ACh significantly increased in C group at Ach 0.3, 1, 3, 10, 30, 100, 300, 1000uM(P<0.05, P<0.01) and increased in D at 0.1, 0.3, 3, 30, 30, 100, 300, 1000uM. 2. The sensitivity of TSM to Ach increased more in A, B group, but it was not significant. 3. The maximal contractile response of TSM to ACh decreased more significantly in C group(P<0.01) and D group(P<0.05) the control group. 4. The maximal contractile response of TSM to KCI decreased more significantly in B group and C group(P<0.001) than in the control group. 5. The counts of lymphocytes in BALF decreased more significantly in B group and D group(P<0.05) than in the control group. 6. The counts of macrophages in BALF decreased more significantly in B group, C(P<0.05) than in the control group. 8. Serum IgE level increased more significantly in B group and C group(P<0.05) than the control group. 9. The counts of WBC, RBC, HGB in blood increased more significantly in A group than the control group.

          생지황음자가미(生地黃飮子加味)가 Streptozotocin으로 유발된 당뇨생쥐에 미치는 영향(影響)

          김희철,최창원,Kim, Hee-Chul,Choi, Chang-Won 대한한방내과학회 2005 大韓韓方內科學會誌 Vol.26 No.1

          First, mice were dosed with 50mg/kg of streptozotocin(STZ) twice every 24 hours to cause high blood-sugar. Then, after three days, mice were injected with 100mg/kg of STZ again. Two different dosages of Saengjihwangeumja-gami were given to the experiment groups: SA group, 15mg/kg/day, and SB group, 90mg/kg/day, in order to determine the effects of Saengjihwangeumja-gami, which has been known to be good for DM(Diabetes Mellitus). By observing weight and blood-sugar level changes, blood tolerance, the numerical value of BUN(Blood Urea Nitrogen) and creatinine in blood, and through light-electronicmicroscopic and immunohistologic investigations of pancreas and kidneys, the following results were obtained: 1. The experiment groups showed a high suppressive effect of weight-loss. 2. The experiment groups' blood-sugar and blood tolerance showed an effective lowering of blood-sugar levels. 3. The experiment groups did not show any noticeable change in the numerical value of BUN and creatinine in blood compared with that of the control groups. 4. The experiment groups showed a higher Insulin positive reaction of pancreatic islets ${/beta}-cell$ than the control groups. 5. The experiment groups showed a higher immuno-reaction against IGF- II than the control groups. 6. Observation of apoptosis of the pancreatic islets showed that the cells of experiment groups were less injured compared with those of the control groups, and fewer apoptag-positive reaction cells were seen in experiment groups than in the control groups. 7. Uunder electron-microscopy, the insulin-containing granules in pancreatic islets ${/beta}-cells$ had increased more in the experiment groups than in the control groups. 8. Under light microscopy, the injury on the inner & outer membrane of the glomerulus and epithelial cells of capillaries and cells among vessels were fewer in the experiment groups than in the control groups. 9. More apoptag-positive reaction cells in the kidney were seen in the control groups than in the experiment groups. 10. PAS-positive reaction substances had increased more in the substrate among the vessels of a glomerulus belonging to the control group than those of the experiment group. 11. Uunder electron-microscopy, the nucleonic membrane, nucleoplasm and mitochondria of proximal and distal renal tubular were more injured in the control groups than in the experiment groups. In conclusion, strong evidence for the efficacy of Saengjihwangeumja-gami in lowering blood-sugar, and in recovery and generation of pancreatic tissues injured by DM was observed. Results suggest Saengjihwangeumja-gami is an effective treatment for DM. Further study of the principles of blood-sugar dropping effects of Saengjihwangeumja-gami are needed, as well as further study of recovery and regeneration of pancreatic tissues injured by DM.

          한국인 정신분열병 환자에서 항정신병 약물의 치료 반응과 도파민 D2, D3 및 D4 수용체 유전자 다형성

          김희철,정성원,김대광,정철호,Kim, Hee-Cheol,Jung, Sung-Won,Kim, Dae-Kwang,Jung, Chul-Ho 대한생물정신의학회 2007 생물정신의학 Vol.14 No.3

          항정신병 약물의 치료 반응을 예측해 줄 수 있는 유전자 지표를 찾기 위한 최근의 많은 약물유전학 연구들은 일관된 결과를 보고하지 못하고 있다. 본 연구는 항정신병 약물의 치료 반응과 도파민 D2, D3 및 D4 수용체 유전자 다형성과 관련성을 조사하였다. 연구 대상은 18~60세에 해당되면서 정신분열병의 DSM-IV 진단기준을 만족하고 본 연구에 대해 서면 동의한 국립부곡병원의 입원 환자 200명이었다. 연구는 대상자들의 입원 당시 병록지를 검토하여 후향적으로 이루어졌다. 대상자들은 퇴원할 당시를 기준으로 약물치료 반응 정도에 따라'반응군'과'비반응군'으로 구분되었으며 양군 사이의 도파민 수용체 유전자 다형성 차이를 비교하였다. 대상자 200명 중에서 188명(94%)이 비전형 항정신병 약물을 사용하였고 반응군은 141명(70.5%)이었다. 도파민 D2 수용체 유전자 Ser311Cys 다형성, 도파민 D3 수용체 유전자 Ser9Gly 다형성, 도파민 D4 수용체 유전자 exon III의 48개 염기반복 다형성에서 반응군과 비반응군 사이의 대립유전자 및 유전자형 빈도의 차이를 보이지 않았다. 결론적으로 본 연구에서는 항정신병 약물의 치료 반응과 도파민 D2 수용체 유전자 Ser311Cys 다형성, 도파민 D3 수용체 유전자 Ser9Gly 다형성, 그리고 도파민 D4 수용체 유전자 exon III의 48개 염기반복 다형 성과는 연관성이 없었다. 향후에는 단일의 항정신병 약물에 대한 전향적인 방법의 통제된 연구가 필요하다. Objectives:A considerable number of pharmacogenetic studies have been performed in recent years to define the association of antipsychotic drug response with dopamine receptor polymorphisms. The purpose of this study was to investigate the relationship between the therapeutic response to antipsychotic drugs and the polymorphisms of the dopamine D2, D3, and D4 receptor genes(DRD2, DRD3 and DRD4, respectively). Methods:We conducted retrospective chart review of 200 consecutively hospitalized patients with the diagnosis of schizophrenia(DSM-IV) who were treated with various antipsychotics(94% atypical antipsychotics) at Bugok National Hospital, Korea. The patients were divided into two groups, responders and non-responders, by responsiveness to antipsychotic drugs according to a four-point scale used in previous studies; responders included moderate to marked responded patients and non-responders included none to minimal responded patients. We analyzed the Ser311Cys polymorphism in the DRD2, the Ser9Gly polymorphism in the DRD3, and the exon III 48 bp repeat polymorphism in the DRD4. Results:Among the total patients of 200, 141(70.5%) were categorized as responders. There were no significant differences in the frequencies of the DRD2, DRD3, and DRD4 alleles and genotypes between responders and non-responders. Conclusion:These results suggest that the Ser311Cys polymorphism in the DRD2, the Ser9Gly polym- orphism in the DRD3, and the exon III 48bp repeat polymorphism in the DRD4 are not associated with the therapeutic response to antipsychotic drugs in Korean schizophrenic patients. A larger prospective study is needed to elucidate the association between antipsychotic response and dopamine receptor gene polymorphism.
