生産環境의 變化에 따른 管理會計시스템의 問題點

千都錠,崔杞豪 全北大學校 1991 論文集 Vol.33 No.-

At present, manufacturing environment is changing rapidly. To take competitive advantages, corporates should have flexibility in production. Conventional management accounting system(CMAS) has provided useful information for manager's decision making under the past manufacturing environment. But CMAS has not unchanged for past half a century. Thus, CMAS has lost its relevance. CMAS made under the past manufacturing environment must change into the new management accounting system(NMAS) under the new manufacturing environment. So far, the researches on the problem of CMAS and the feature of NMAS have been conducted conceptually. However, the empirical researches on NMAS are needed. As a conclusion, more field based researches such as case studies, field experiments and field surveys are needed to design NMAS.

천강훈,이기철,이정호,최영민,전성일,정홍경,류정환,최미 大韓神經精神醫學會 1998 신경정신의학 Vol.37 No.5

연구목적 : 강박장애의 생물학적 원인론중 세로토닌-도파민 상호작용 가설에 적합한 5-HT₂ 수용체와 도파민 D₂수용체를 동시에 차단하는 약물의 일종인 cloazpine과 세라토닌 재흡수 차단약물인 clomipramine, 그리고 도파민 D₂수용체 차단 약물인 haloperidol을 실험백서의 강박장애 동물모형에 투여하여 자발적 교대 행동에 미치는 영향을 비교, 측정하였다. 그 결과로서 1) 세라토닌 수용체와 도파민 수용체를 동시에 차단하는 약물의 효과를 확인하고, 2) 세라토닌과 도파민 수용체 동시차단 약물의 효과가 확인되면 임상적으로 기존의 세라토닌 재흡수 차단약물에 반응을 보이지 않는 강박장애 환자 치료에 세라토닌 수용체와 도파민 수용체를 동시에 차단하는 비전형적인 항정신병 약물들이 강박장애의 치료에 유용하게 사용될 수 있는 가능성을 제시하고자 하였다. 실험재료 및 연구방법 : 실험동물은 동일한 배에서 출생한 수컷 Spraque-Dawley 백서를 사용하였다. 자발적 교대 행동(spontaneous alternation behaviour : 이하 SAB)을 시험하기 위해 SAB의 기준치를 구하고 난 후, SAB을 차단하기 위한 방법으로 비선택적 세라토닌 순응제인 5-MeODMT(5-methoxy-N, N-dimethyltrytamine)를 투여하였다. 실험백서들을 clomipramine(5㎎/㎏), clozapine(10㎎/㎏), clozapine(20㎎/㎏), haloperidol(0.1㎎/㎏), 그리고 saline(0.2cc) 투여군으로 나누고 21일에 걸쳐서 복강내 주사하였다. 실험약물 투여가 끝난 다음날인 22일째에 5-MeODMT(5-methoxy-N, N-dimethyltryptamine : 1.25㎎/㎏/IP)를 각각의 실험동물군에게 투여하고 실험약물의 만성투여가 5-MeODMT 투여로 억제되는 SAB을 얼마나 호전시키는 지를 측정하였다. 모든 자료는 SPSS for window 7.5으로 통계처리 하였다. SAB의 기준치 5-MeODMT 투여로 억제되는 SAB의 효과, 실험약물의 만성투여에 따른 SAB의 변화는 일원분산분석을 사용하였으며, 사후검증은 Scheffe 검증을 적용하였다. 각 군내에서 기준치와 5-MeODMT 투여로 억제되는 SAB의 변화, 그리고 실험약물의 만성투여에 따른 SAB의 변화는 다중변량분석을 시행하였다. 결과 및 결론 : 역구결과 실험동물은 T-형 미로의 SAB에서 평균 1.33±0.36회의 훈련 기준치를 보였다. 5-MeODMT 주사후 , 실험동물의 SAB치는 3.12±0.63회를 보여 강박행동이 유발하였다. 21일간의 실험약물 투여후, 22일째에 5-MeODMT 주사에 대한 SAB의 반응은 clozapine 투여군과 clomipramine 투여군이 halo-peridol 투여군과 saline 투여군에 비하여 유의하게 낮은 수치를 보여 5-MeODMT투여로 억제된 SAB을 호전시키는 소견을 나타냈다. 각 실험동물군 내에서 각각의 SAB 훈련 기준치와 실험약물 투여 전후에 5-MeODMT 투여로 인한 SAB을 비교한 바, clomipramine 투여군은 약물투여 전에 5-MeODMT로 억제된 SAB이 약물투여후 의미있게 호전되었다. 한편, clozapine 투여군도 약물 투여전에 5-MeODMT로 억제된 SAB가 약물투여후 의미있게 호전되었으며, 이런 SAB의 호전은 clomipramine 투여군보다 우수하였다. 이상의 연구결과로 보아, 강박장애의 생물학적 병리론을 이해하는데 있어 세라토닌-도파민 상호작용 가설이 의미가 있음을 추정할 수 있었다. 향후, 강박장애의 임상치료에서 전형적인 SSRIs 치료에 반응치 않는 환자들에게 세라토닌-도파민 동시차단제인 비전형적인 약물의 단독투여를 시행하는 후속연구를 기대해 본다. Objectives : This study was designed to evaluate the role of the 5-HT₂and dopamine D₂antagonist on spontaneous alteration behaviour which is an animal modal of obsessive-compulsive disorder in rat. On the basis of serotonin-dopamine interaction hypothesis, the effect of clozapine was evaluated by applying the suppressed spontaneous alternation behaviour model. Methods : The apparatus for spontaneous alternation behaviour was a black plexiglas T-maze with distinctive black and white goal boxes. Black guillotine doors separated the start box and the goal boxes from the main body of the T-maze. Small cups of chocolate milk were placed in the corners of both goal boxes. At 24 hours prior to experiment, rats(Spraque-Dawley) food-deprived. The food-deprived rats were put into T-maze, in which both goal boxes were baited with small amounts of chocolate milk. Each rat was given 2 set of 7 trials during which it was placed in the start box and allowed to choose one of the goal boxes for each time. The mean number of choices until the occurrence of spontaneous alternation behaviour were checked. After baseline of the number of choices of spontaneous alternation behaviour was stabilized, the spontaneous alternation was disrupted by nonselective 5-HT agonist, 5-MeODMT(1.25mg/Kg/IP), The experimental animals were stratified into 5 groups :clomipramine(5mg/Kg/IP), clozapine(10mg/Kg/IP), clozapine(20mg/Kg/IP), haloperidol(0.1mg/Kg /IP), and saline(0.2cc/IP) control groups. They all went through 21 days fo treatment(intraperitoneal). The protective effects against the 5-MeODMT-induced disruption of spontaneous alternation behaviour were evaluated on the next day of drug treatment in each group. Results : 1) SAB was suppressed by 5-MeODMT injection. 2) After 21 days of the drug treatment, the clozapine and the clomipramine groups showed significant difference from the haloperidol and the saline control groups in the reversal of 5-MeODMT-induced suppression of spontaneous alternation behaviour. 3) The clozapine (20mg/kg/IP) group was superior to the clomipramine group in the protective effect of 5-MeODMT-induced suppression of spontaneous alternation behaviour. Conclusion : In clinical situation, the we think that atypical antipsychotic drugs those acting as serotonin and dopamine receptor antagonist with no extrapyramidal side effect can be beneficial to improve the symptoms of obsessive-compulsive disorder.

Extrapyramidal movement disorders are divided descriptively into hypokinesias (such as parkinsonism), characterized by poverty and slowness of movement ; hyperkinesias (such as chorea, athetosis, dystonia, ballism, etc.), manifested by abnormal involuntary movement. Chorea refers to widespread arrythythmic movements of a forcible, rapid, jerky, restless type. Choreic movements are noted for their irregularity and variability. They are generally continuous, may be simple or quite elaborate, and affect any part of the body. Dystonia refers to abnormally increased muscular tone that causes fixed abnormal postures. Some patients with dystonia also have shifting postures, resulting from irregular, forceful twisting movement that affect trunk and produce bizarre, grotesque movements and positions of the body. The most frequent and familiar type of focal dystonia is spasmodic torticollis. It consists of an involuntary turning of the head to one side - intermittent at first, then gradually worsening to the point of being more or loss continuous. The combination of blepharospasm and oromandibular dystonia is sometimes referred to as Meige's syndrome. We report two patients with dystonia and chorea in cerebral infarction at basal ganglia. We have experienced good improvement by the oriental medicine and acupuncture trearment. The acupuncture points of LI 4, ST 36, TE 3, GB 34, GB 41, LR 3, GB 39 were used. The therapies of herb-medicine were treated by Zibu-Ganshen, Huoxue-Xifeng-Tongluo.

이기철,이정호,김진규,정홍경,천강훈,류정환,최영민,전성일 대한생물치료정신의학회 1998 생물치료정신의학 Vol.4 No.2

Objectives : Recently, some case reports have shown that risperidone is effective to refractory obsessive-compulsive disorder. Possible explanations for efficacy of risperidone in refractory obsessive-compulsive disorder maybe due to that it is both serolonin and dopamine receptor antagonist. On the basis of serotonin-dopamine interaction hypothesis, a biological etiology of obsessive-compulsive disorder, the effect of risperidone was evaluated to the suppressed spontaneous alternation behaviour of animal model of obsessive-compulsive disorder in rats. Methods : The apparatus for spontaneous alternation behaviour was a black plexiglas T-maze with distinctive black and white goal boxes. Black gullotine doors separated the start box and the goal boxes from the main body of the T-maze Small cups were placed in the corners of both goal boxes(all arms measured 50×10cm) 24 hours prior to experiment, rats(Spraque-Dawley) were food-deprived. The food-deprived rats were put into T-maze, in which both goal boxes were baited with small amounts of chocolate milk. Each rat was given 2 set of 7 trials during which it was placed in the start box and allowed to choose the one of the goal boxes for checked. After baseline of the number of choices of spontaneous alternation behaviour was stabilized, the pontaneous alternation disrupted by nonselective 5-HT agonist, 5-MeODMT (1.25mg/kg/IP). The experimental animals were stratified into 5 groups, fluoxetine(10mg/kg/IP), risperidone(0.1mg/Kg/IP), haloperidol(0.1㎎/Kg/IP), fluoxetine(10mg/Kg) with haloperidol(0.1 mg/Kg), and saline(0.5cc/IP) control group. Each drugs were injected for 21 days as a chronic treatment. The protective effects were evaluated on the nest day of discontinuation of the each drugs among 5 groups. Results : 1) After 21 days of the drug treatment, the risperidone group and the fluoxetine group showed significant difference from the haloperidol group and the saline control group on the protection of the 5-MeODMT induced suppression of spontaneous alternation behaviour. 2) The fluoxetine group and fluoxetine with haloperidol group showed significant difference between before and after treatment in the protection of 5-MeODMT induced suppression of spontaneous alternation behaviour. The risperidone group also showed significant difference between before and after treatment in the protection of 5-MeODMT induced suppression of spontaneous alternation behaviour, but the protective effect of risperidone was superior to fluoxetine. Conclusion : These findings suggest that both risperidone and fluoxetine have a favorable effect in the protection of 5-MeODMT induced suppression of spontaneous alternation behaviour. We think that risperidone can be possible alternatives to SSRIs in the treatment of refractory obsessive-compulsive disorder in clinical situation.

(±)-Camphor가 ICR 마우스 수컷의 간 cytochrome P450 효소 활성에 미치는 영향

오은경,박형건,배기현,최옥진,최은경,최창근,한진희,정태천 한국환경독성학회 2002 환경독성보건학회지 Vol.17 No.4

Effects of (±)-camphor on liver cytochrome P450 enzymes were investigated in male ICR mice. Mice were treated intraperitoneally with 0, 200, 400 and 800 mg/kg of (±) -camphor in corn oil for 3 consecutive days. Twenty four hr after the final treatment, the animals were subjected to necropsy. The activities of serum aspartate aminotransferase and serum alanine aminotransferase were slightly changed by the treatment with (±)-camphor at the doses used. Administration o(±)-camphor to mice significantly induced the hepatic activities of pentoxyresorufin O-depentylase and benzyloxyresorufin O-debenzylase and weakly induced ethoxyresorufin O-deethylase in dose-dependent manners. The present results suggested that (±)-camphor might act as a relatively specific inducer of hepatic cytochrome P450 213 in male ICR mice.
