본 연구에서는 KI-188 칼슘과 KI-180 조성물이 성장발육에 미치는 효과를 조사하였다. 시험기간중 KI-188 칼슘과 KI-180 식이군이 대조군 보다 성장률과 평균 식이섭취량은 증가하였다. 체장은 KI-188 칼슘과 KI-180 식이군이 대조군에 비해 평균 3.55 mm 더 길었고, 등뼈길이는 KI-180 식이군이 대조군 보다 통계적인 차이는 없었지만 0.5 mm 더 길었다. 대퇴골 무게는 KI-188 칼슘과 KI-180 식이군이 대조군에 비해 통계적으로 무거웠으며, 대퇴골길이는 대조군에 비해 각각 평균 0.89, 1.09 mm 더 길었다. 혈당, 총콜레스테롤 및 중성지방 농도는 차이가 없었고, 칼슘농도는 KI-188 칼슘과 KI-180 식이군 보다 대조군이 유의하게 높았다. 백혈구와 혈소판수는 차이가 없었고, 적혈구, 혈색소 및 헤마토크릿치는 대조군이 KI-188 칼슘과 KI-180 식이군 보다 통계적으로 높았다. ALP활성은 KI-180 식이군이 대조군 보다 통계적으로 높았고, osteocalcin농도는 KI-188 칼슘과 KI-180 식이군이 대조군에 비해 통계적으로 유의하게 높았다. 혈청 testosterone 농도는 KI-188 칼슘과 KI-180 식이군과 대조군 간에 차이가 없었다. IGF-1과 IGFBP-3 농도는 KI-180 조성물이 대조군 보다 각각 20%, 11% 정도 유의하게 더 높았다. 이상의 결과를 검토할 때 KI-188 칼슘과 KI-180 조성물은 어린쥐의 성장과 골격의 발달을 촉진시키고, 성장호르몬의 분비능을 양적으로 유도하여 전반적인 성장발육에 유효한 작용이 있는 것으로 사료된다. Herbs have active components that promote the growth rate of both animals and human. The KI-180 and KI-188 calcium food formulae contain Acanthopanacis cortex, Bombysis corpus and hoelen, seaweed calcium, chlorella extract, spirulina, colostrum powder, and other natural and functional components. We evaluated the growth-promoting effects of these formulae by analyzing the weight, femur and backbone, alkaline phosphatase, osteocalcin, testosterone, insulin-like growth factor (IGF)-1, and IGF binding protein-3 (IGFBP-3) of growing rats. Growing rats administered with KI-180 and KI-188 calcium showed the increase of body weight, body length, and femur weight and length of growing rats. In addition, administration of KI-180 and KI-188 calcium increased the alkaline phosphatase activity, the levels of osteocalcin and the growth hormones IGF-1 and IGFBP-3 of growing rats. The impact of KI-180 and KI-188 calcium on the physical development of growing rats suggests that the incorporation of these food formulae in the diets of growing children may promote the physical development.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

레이저의 구강내 산 생성 세균인 S. mutans에 대한 증식 및 기능 억제효과를 평가하기 위하여 S. mutans KCTC 3065가 포함된 세균 pellet에 Er:YAG 레이저와 Nd:YAG 레이저를 비접촉식 방법으로, 조사세기 50mJ, 조사시간 5초, 그리고 pulse repetition rate를 각각 10Hz와 30Hz로 하여 조사하고 세균 군락수, 산 생성능, 불용성 세포외다당류의 합성량을 측정하여 다음과 같은 결과를 얻었다. 1. Chinese ink로 photosensitization을 시행한 후 Nd:YAG 레이저를 조사한 경우가 S. mutans의 증식을 가장 많이 억제하였으며 Er:YAG 레이저 조사도 증식을 억제하였다. Chinese ink를 사용하지 않고 ND:YAG 레이저를 단독으로 조사한 경우는 S. mutans의 증식을 억제하지 못하였다. 2. Chinese ink로 photosensitization을 시행한 후 Nd:YAG 레이저를 조사한 경우가 일정기간 동안 S. mutans의 산생성능을 가장 많이 억제하였으며 Er:YAG 레이저 조사도 산 생성능을 억제하였다. Chinese ink를 사용하지 않고 Nd:YAG 레이저를 단독으로 조사한 경우는 S. mutans의 산 생성능을 억제하지 못하였다. Er:YAG 레이저와 Chinese ink로 photosensitization을 시행한 후 Nd:YAG 레이저를 조사한 경우는 pulse repetition rate가 클수록 전반적으로 세균의 산생성능을 더 많이 억제하였다. 3. 레이저 조사는 S. mutans의 불용성 세포외다당류의 합성에 영향을 미치지 못하였다. 이상의 결과로 보아 Er:YAG 레이저와 Chinese ink로 photosensitization을 시행한 후의 Nd:YAG 레이저 조사는 일정시간 동안 S. mutans의 증식과 산 생성능을 억제시키므로써 치아우식증 예방효과를 얻을 수 있다고 사료되나 억제효과가 오래가지 않아 임상적으로 효과를 얻기 위해서는 자주 조사를 해주어야 한다는 문제점을 안고 있어 임상적으로 치아우식증 예방이란 단독 목적으로 사용하기에는 실용성이 크지 않다고 사료된다. This was performed to evaluate the inhibitory effect of laser on the growth of S. mutans. The bacterial pallets containing S. mutans KCTC 3065 were irradiated with Er:YAG laser and Nd:YAG laser by non-contact method at an intensity of 50mJ for 5 sec with the pulse repetition rates of 10Hz and 30Hz, respectively. The following results were obtained on colony count, acid producing ability, and the amount of insoluble extracellular polysaccharide synthesis. 1. The irradiation of Nd:YAG laser after photosensitization with Chinese ink inhibited the proliferation of S. mutans the most, and the irradiation of Er:YAG also inhibited the proliferation. However, the irradiation of Nd:YAG laser alone could not inhibited the proliferation of S. mutans. The pulse repetition rate did not affect significantly on the proliferation of bacteria in overall. 2. The irradiation of Nd:YAG laser after the photosensitization with Chinese ink inhibited the acid production of S. mutans the most for a certain period of time. Er:YAG laser also inhibited acid production. When Nd:YAG laser was used alone, the acid production of S. mutans was not been inhibited. The irradiation of Nd:YAG laser after photosensitization with Chinese ink inhibited the acid production ability of bacteria the most as the pulse repetition rate increased. 3. Laser irradiation did not inhibited the synthesis of insoluble extracellular polysaccharide of S. mutans. From these results, we conclude that the irradiatioin of Er:YAG laser and Nd:YAG laser after photosensitization with Chinese ink would inhibit the proliferation and acid production by S. mutans, which may prenent dental caries. However, this effect does not last long time so that the laser irradiation should be repeated frequently in order to obtain clinical effect; thus, this laser irradiation would not have a clinical usefulness in preventing dental caries when used solely.

韓元熙,周赫鍾,孟琦錫 嶺南大學校 工業技術硏究所 1975 연구보고 Vol.3 No.1

Wasted plastics were collected and selected through the specific gravity method, the combustion method and coloring reaction method, and these methods showed to us various physical properties of wasted plastics. Degradation of wasted plastics was carried out by the thermodegradation method and the catalytic degradation in the presence of catalystes; Al₂O₃, Bentonite and Kaoline. Generally, these materials showed the affects of lowering decomposition temperature of wasted plastics and those of increasing the yield of recovery oil. Bentonite brought the best result of these catalystes. It was possible to polymerize the recovery oil extracted from the decomposed oil of P.S. collected below 180℃ and from that of PMMA collected below 270℃. Out of the polymers of good qualities, products compared with the other wasted plastics could be obtained. The recovery oils extracted from P.P, P.E., P.S. and P.M.M.A. had high calories and low flash points enough to be utilized as liquid fuel. Prepolymers of P.S. and P.M.M.A. are able to be used as coating material for metal.

한성철,류종서,이기영,김도만,최춘순 全南大學校 觸媒硏究所 2003 觸媒硏究 論文集 Vol.24 No.-

We studied the oxidation of docosahexaenoic acid(DHA: C22: 6ω-3). β-Cyclodextrin(CD) inclusion complexes(ICs) of DHA were prepared with antioxidant such as α-tocopherol and BHT, and microcapsulated with Curdlan and Pullulan. Identification of their structural features of ICs were observed with the use of SEM, FTR, and XRD. Methods for quantitative analysis of DHA were used: TLC scanning method and TBARS(Thiobarbituric acid reactive substance) method. As a result, we observed the formation of ICs and estimated antioxidant effect. In this work, loading efficiency of DHA in ICs was about 25%, and the antioxidant effect of α-tocopherol was higher than that of BHT. When ICs containing DHA was microcapsulated with curdlan and pullulan, the loading efficiency was less than 5%.

육두구의 形態 鑑別에 관한 硏究

韓孝尙,吉基正,李暎鍾 대한본초학회 2005 大韓本草學會誌 Vol.20 No.1

Objectives : Myristicae Semen is the seed of Myristica fragrans Houttuyn. Recently, the seed of Myristica argentea Warburg is also sold as a fake of Myristicae Semen. Thus, in order to distinguish Myristica fragrans Houttuyn and Myristica argentea Warburg, their external, internal, and flour states were observed via microscopic examination. Method : The slice of the tested material made by paraffin section technique was colored with Safranine Malachite Green contrast methods, and the flour of it was mounted by the liquid made by the same ratio of each of glycerin, acetic acid, and water, and then observed and photographed by olymphus-BHT. Result 1. The seed of Myristica fragrans Houttuyn is oval with a length of 2~3cm and diameter of 1.5~2.5 cm, while the seed of Myristica argentea Warburg is of a longer oval shape with a length of 2.5?3.5cm and diameter of 1.5cm. 2. There was no difference between the internal parts of the cross-sections of Myristica fragrans Houttuyn and Myristica argentea Warburg. 3. There was no difference between the flour states of Myristica fragrans Houttuyn and Myristica argentea Warburg. Conclusion : There was a distinctive difference between the external forms of Myristica fragrans Houttuyn and Myristica argentea Warburg, while there was no significant difference in their internal and flour states. This makes it difficult to distinguish them via microscopic examination, when cut by cross-sections or grounded into flour states. Therefore, they should be distinguished through TLC, or some research on the characterising compound is needed.
