Purpose : In order to study the effectiveness of East-West pain treatment on central poststroke pain(CPSP), we evaluated its effect on alleviation of pain and rehabilitation of CPSP Patients who were treated with electroacupuncture and west pain treatment for four weeks. Methods : Twenty four patients diagnosed by their pain characteristics of central pain from stroke were treated with sympathetic nerve block, gabapentin, amitriptyline, and electroacupuncture for four weeks. Pain intensity through the visual analogue scale(VAS), and improvements of mobility and rehabilitation through the modified Barthel index(MBI) and Rankin scale(RS), respectively, before and after pain treatment were also assessed. Results : VAS pain scores were significantly improved from 7.7±1.7 to 4.4±2.0 with pain treatment(p<0.05). In accordance with improvement of pain scores, RS and MBI scores were also improved from 2.88±0.95 to 2.13± 1.01 and from 83.0± 16.9 to 94.7±9.5(p<0.05), respectively, with pain treatment(p<0.05). Conclusions : It was suggested that the active pain treatment was contributed to the rehabilitation of CPSP patients, resulting in improvement of quality of life of CPSP patients. Futhermore, East pain treatment in combination with West pain treatment may be useful modality to alleviate CPSP.

Amphotericin B의 投與가 마우스의 免疫反應에 미치는 影響

李正鎬,黃翼根 全北大學校 1983 論文集 Vol.25 No.-

Amphotericin B(AmB)가 免疫反應에 關與하는 機轉을 究明하기 爲한 基礎資料를 얻고자 마우스를 모델로 抗原(SRBC)의 感作量, AmB의 投與時期 및 投與量에 따라 AmB가 細胞性免疫反應에 미치는 效果를 足蹠腫腸反應檢査 및 脾臟細胞의 로젵 形成能儉査로 測定하였던 바 다음과 같은 結果를 얻었다. 抗原感作(10^8SRBC/mouse)과 同時에 여러 濃度의 AmB를 投與한 後 發顯되는 DTH는 AmB를 350㎍Υ mouse의 濃度로 投與한 群에서 가장 顯著한 增加를 보였다. 여러 濃度의 感作抗原下에서의 Arthus反應이나 DTH는 모두 投原量에 關係없이 AmB(350㎍/mouse)를 投與한 群에서 對照이 比하여 大體로 增加되었으며, 對照群에서의 最適感作抗原量은 10^7SRBC/mouse이었으나, AmB를 投與한 群에서는 10^8SRBC/mouse이었다. AmB(350㎍/mouse)의 投與時期에 따른 感作抗原(10^8SRBC/mouse)에 對한 DTH는 AmB를 感作 後投與한 群에서는 對照에 比하여 差異ffm 보이지 않았으나 AmB를 抗原感作 前 또는 感作과 同時에 投與한 群에서는 對照에 比하여 DTH가 增加되었는데 特히 AmB를 抗原感作과 同時에 投與한 群에서 그 報加가 가장 顯著하였다. AmB(350㎍/mouse)의 投與時期에 따른 感作마우스(10^8SRBC/mouse)의 로젵 形成率AmB를 抗原 感作前에 投與한 群에서는 對照에 比하여 오히려 減少되었으나, AmB를 抗原感作과 同時 또는 感作 後에 投與한 群에서는 對照에 比하여 增加되었는데 特히 抗原感作 後 4日에 AmB를 投與한 群에서 그 增加가 가장 顯著하였다. 以上의 結果로 AmB가 免疫反應을 增强시키는 最適感作抗原濃度, AmB의 最適投與量 및 投與時期 等을 밝힐 수 있었으며, AmB가 免疫反應에 關與하는 몇가지 可能性있는 機轉을 類推할 수 있었다. Amphotericin B (AmB), a polyene antibiotic that binds to choresterol in the plasma membrane of eukaryotic cells, is clinically used in the treatment of systemic fungal infection. Using in vitro and in vivo models, several investigators have demonstrated both immunostimulatory and immunosuppressive effect of AmB. The immunostimulatory effect of AmB may be a useful adjunct to host defenses against fungi, while the immunosuppressive activity may have deleterious effects. But there has still been no report to evaluate the effects of AmB on delayed hypersensitivity (DTH) and rosette forming cell reaction (RFR). Therefore, this present study was attempted to investigate the immunomodulating effect of AmB on the reponses to sheep erythrocytes(SRBC) by footpad swelling reaction and rosette formation of spleen cells in ICR mice. DTH in AmB-treated mice (17.5㎎/㎏ per mouse) were generally increased compared to those of PBS-treated controls. The optimal immunopotentiating effect of AmB was provoked when the mouse was sensiitzed with SRBC at 10-fold higher doses of antigen (10^8SRBC/mouse) than those required for optimal immune response in PBS-treated control mice (10^7SRBC/mouse). DTH of AmB-treated mice were enhanced when AmB was injected into mice before or at the same time of SRBC-sensitization, particularly the enhancement degree of DTH was more prominent when mice were treated with AmB at the same time of sensitization than before. However, there was no significant difference in the response when AmB given after sensitization. The percentage of RFR was decreased compared with those of control when AmB was administrated before SRBC-sensitization, but was increased when AmB was treated after SRBC.

한국인 정신분열병과 양극성 기분장애에서 Ciliary Neurotrophic Factor(CNTF)유전자 변이에 관하여

이충숙,신석철,지익성,왕성근,이영호 대한신경정신의학회 2000 신경정신의학 Vol.39 No.4

정신분열병과 양극성 기분장애 같은 주요 정신질환의 발병에서 유전적 요인이 중요하게 작용한다. 최 근 정신분열병과 양극성 기분장애의 원인을 신경병리학적 연구와 신경영상학적 연구를 통하여 신경발달 학인 면에서 이해하려고 시도하고 있다. Ciliary neurotrophic factor(CNTF)는 해마신경원와 내측 중 격신경원을 포함한 다양한 신경세포의 강력한 생명 유지인자로 작용하여 중추신경계의 발달과 유지와 관련이 있는 것으로 여겨지면서, 주요 정신질환의 원인적인 요인으로 제시되고 있지만 이에 대한 연구결 과는 일치되지 못한 상태이다. 이에 저자 등은 한국인 정신분열병 환자 112명과 양극성 기분장애 환자 81명 그리고 정상 대조군 125명을 대상을 CNTF 유전자 변이와 연관성을 알아보고자 본 연구를 시행하여 다음과 같은 결론을 얻었다. CNTF의 유전자형은 정신분열병 환자군에서 N/N 80(70.4%), N/M 32(28.6%), M/M 0(0.0%)이 었고, 양극성 기분장애 환자군에서 N/N 58(71.6%), N/M 23(28.4%), M/M 0(0.0%)이었으며, 정상 대조군에서는 N/N 94(75.2%), N/M 30(24.0%), M/M 1(0.8%)이었다. 대립유전자의 빈도는 정신분 열병 환자군에서 N 192(85.7%), M 32(14.3%)이었고, 양극성 기분장애 환자군에서는 N139(85.8%), M 23(14.2%)이었으며, 정상 대조군에서는 N 218(87.2%), M 32(12.8%)이었다. 3군간의 유전자형과 대립유전자에서 유의한 차이가 없었다. 이러한 연구결과 한국인 정신분열병과 양극성 기분장애에서 CNTF 유전자의 변이가 원인적 요인으 로 작용할 것이라고 볼 수 없었다. Genetic factors play an important role in the development of schizophrenia and bipolar disorder, and recently the neural maldevelopment hypothesis is suggested by neuropathological and neuroimaging studies. Neurotrophic factors, including ciliary neurotrophic factor(CNTF), play a central role in the regulation of neural development. This study was designed to investigate the association between the null mutation of CNTF gene and schizophrenia and bipolar disorder in a Korean population. The CNTF gene were typed with polymerase chain reaction in 112 patients with schizo-phrenia, 81 with bipolar disorders and in 125 healthy controls. The distributions of the CNTF genotype in schizophrenic patients with N/N, N/M, M/M were 80(71.4%), 32(28.6%), 0(0%), in bipolar disorders were 58(71.6%), 23(28.4%), 0(0%) and in the controls were 94(75.2%), 30(24.0%), 1(0.8%). The allele frequencies of the CNTF gene in schizophrenic patients with N and M were 192(85.7%), 32(14.3%), in bipolar disorders were 139(85.8%), 23(14.2%), and in the control were 218(87.2%), 32(12.8%). There were no differences in the genotype distributions and the allele frequencies of CNTF gene null mutation among the 3 groups. These results suggest CNTF gene null mutation is not causally related to the development of schizophrenia and bipolar disorder in Korea.

李根常,尹益錫 건국대학교 1978 論文集 Vol.7 No.1

This study was conducted to investigate the effects of several herbicides under oversowing and the application methods of Gramoxone as well as effects of burning. These trials were established in 1974 on natural grassland in Che Ju where Miscanthus purpurascens and Imperata cylindrica are dominant and foil type is volcano ash. The results obtained from 3 years experimentation are summarized as follows. 1.Gramoxone, of immediate effect, and Round-up, of slow effect showed similiar effect of weed control and both herbicides did not affect on emergence and early growth of sown species. 2.In case of oversowing, herbicides application did not increase the total dry matter yield but the yield of sown species was increased significantly (P < 0.01). There were, however, no significant differences in grasses yield among different herbicides. 3.In the natural grassland where Miscanthus purpruascens and Imperata cylindrica were dominant, the optimal amounts of herbicides were 400cc in Gramoxone and 600cc in Round-up per 10 a when oversowing method was applied. 4.The times of herbicide application and burning of grassland before sowing did not affect on total dry matter yields, but burning helped emergence and establishment of the sown species compared to no burning. 5.When a pasture was established by oversowing the clover content was higher with herbicide application and increased with increasing rate of herbicides.

In order to assess the efficacy and safety of clozapine, 50 in-patients with treatment-resistanat schizophrenia were evaluated using PANSS(Positive and Negative Symptome Scale for Schizophrenia), CGI(Clinical Global Impression), AMS(Abnormal Involuntary Movement Scale), Adverse Event-Somatic Symptoms, Neurological Rating Scale for EPS before and during treatment. Mean daily dosage of clozapine was 344.15±123.43mg at 12th week. A clinically significant improvement in positive, negative, and general psychopathology was noted as early as week 2 through 12 week. The tolerability of clozapine was generally found to be good. Drowsiness/sleepiness, Hypersalivation, and Constipation were the most common side effects. There was no neutropenia, and 3 patients suffered from seizures. These results suggest that clozapine is worth considering for the treatment-resistant patients
