Ganoderma lucidum 균주는 인공 배지 상에서 광에 의하여 자실체 원기가 형성되었으며, 광질이 자실체 원기 형성에 미치는 영향을 조사한 결과, 자실체 원기 형성능을 가지고 있는 5균주중 3균주는 공시한 모든 형광등의 아래에서 즉, BLB, 순청색, 순녹색, 순황색, 순적색 형광등의 아래에서 자실체 원기가 형성되었고, 2균주는 BLB 형광등을 제외한 가시광선 영역에서 형성되었다. 그러나 암상태에서는 공시한 모든 균주가 자실체를 형성하지 않았다. 자실체 원기는 광도 0.05에서 10.0 μmol m^-2 s^-1의 범위에서 형성되었고, 광도가 0.5 μmol m^-2 s^-1 이상에서는 자실체 원기의 수가 감소하였다. 주기적인 광조사가 자실체 원기의 형성에 미치는 영향을 조사한 결과, G1-009 균주는 자실체 원기의 수와 무게가 연속광을 조사한 경우보다 증가하였다. 자실체 원기를 형성하기 위해서는 최소 4일간의 광조사가 필요하였다. 단색광의 조사가 자실체 원기의 형성에 미치는 영향을 조사한 결과 G1-003 균주는 400에서 800 nm의 모든 단색광 처리구에서 자실체 원기가 형성되었고, 그 외의 4균주는 400에서 500 nm, 그리고 700에서 750 nm 범위에서 형성되었다. The objective of this research was to determine the effect of light quality on formation of fruit body primordia (FBPs) of Ganoderma lucidum. To achieve this 5 isolates of the fungus that develops fruit body primordia on nutrient agar media were incubated with or without continuous irradiation. The fluorescent lamps used different colors such as black light blue (BLB), pure blue (P-B), pure green (P-G), pure yellow (P-Y) and pure red (P-R). Effect of periodic light and dark exposures on FBP formation of isolate G1-009 was investigated. The FBP formation in G. lucidum isolates was also tested under nomochromatic light produced by the combination of interference filters and colored glass filters. Three isolates produced FBPs under all kinds of fluorescent lamps, whereas two induced FBPs only under visible light except for BLB fluorescent lamp. However, these isolated did not form FBPs in the dark. The FBP was formed at light intensity from 0.05 to 10.0 μmol m^-2 s^-1, and begun to reduce its number as light intensity increase over 0.5 μmol m^-2 s^-1. When the isolate was incubated under periodic light and dark exposures, the number and weight of FBP increased as compared with those under continuous light. Initiation of FBP requires at least 4 days of light illumination. Although isolate G1-003 produced FBPs in a wide range of 400 to 800 nm, other four isolates had two effective regions 400 to 500 nm and 700 to 750 nm in FBP formation.

이기헌,황현식 전남대학교 치과대학 1996 전남치대논문집 Vol.8 No.1

The purpose of this study was to evaluate the effect of splinting methods on the rearrangement of periodontal fibers after experimental tooth movement. Orthodontic force was applied by placing closed coil spring between upper third incisor and canine in seven dogs, weighing 20 kg or more. After 3 weeks of force application, 0.0215 inch multistrand wire and polyethylene ribbon were bonded to each side, as a flexible and rigid splinting respectively in 6 experimental animals. The remaining 1 served as the control group. Each 2 animals were sacrificed at 4, 8 and 12 weeks after splinting respectively and prepared histologically for hematoxyline-eosin and Masson's trichrome staining. The results of this study were obtained as follows : 1. After tooth movement, periodontal space was narrowed and periodontal fibers were thick on pressure side, while elongated fibers were observed on tension side. 2. After 4 weeks of retention, the rearrangement of periodontal fibers was observed in the flexible splinting group but not in the rigid splinting group. 3. After 8 weeks of retention, the rearrangement of periodontal fibers was observed in both groups but the difference could not detected between two groups. 4. During the retention period, the rearrangement of periodontal fibers was faster in tension side than in pressure side. These results show that the rearrangement of periodontal fibers is also obtained by rigid splinting after tooth movement. It is suggested that the rigid splinting by polyethylene ribbon can be used as a way of postorthodontic retention.

Flurazepam이 가토 혈중 주정농도에 미치는 영향에 관한 실험적 연구

이기연 大韓神經精神醫學會 1981 신경정신의학 Vol.20 No.4

Flurazepam is one of several 1,4-benzodiazepine derivatives widely used in clinical practice. Chemically, it is 7-chloro-1-(2-diethylaminoethyl)-5-(o-flurophenyl)-1,3-dihydro-2H-1,4-benzodiazepine-2-one dihydrochloride. The sedative, anticonvulsant, and muscle relaxant effects of flurazepam on experimental animals resemble those of other benzodiazepines. But, it is used as a safe and potent hypnotic rather than as an anti anxiety agent. Investigators suggested that any new psycho-tropic drug should be tested for their interaction with alcohol, because it might precipitate risk situation in cases of consuming alcohol concurrently. In view of these facts, the author conducted an animal experiment to investigate the effects of flurazepam on blood alcohol level in rabbits. Material and method 1. The experimental work was done on mature rabbits of both sexes, weighing about 2kg. 2. The experimental animals were divided into two groups: the control and the experimental group. 3. The control group was given alcohol alone. 4. The experimental group was divided into 4 subgroups: a) Alcohol plus flurazepam, 15mg/kg of body weight daily for 5 days. b) Alcohol plus flurazepam, 15mg/kg of body weight daily for 10 days. c) Alcohol plus flurazepam, 30mg/kg of body weight daily for 5 days. d) Alcohol plus flurazepam, 30mg/kg of body weight daily for 10 days. 5. Flurazepam was given orally in a single daily dose at a fixed time. The last dose was given one hour and a half before alcohol administration. 6. In all groups, 20% ethanol solution was slowly given in a dose of 5.0ml/kg of body weight for 5 minutes by intravenous route. 7. All of the blood specimens were obtained by cardiac puncture at both 15 and 45 minutes after alcohol administration. 8. The blood alcohol level was determined by Cavett's method. Results 1. Alcohol plus flurazepam, 15mg/kg of body weight daily for 5 days. Flurazepam did not change the blood alcohol level significantly at both 15 and 45 minutes after alcohol administration. )respectively, p>0.1) 2. Alcohol plus flurazepam, 15mg/kg of body weight daily for 10 days. In this group, flurazepam elevated the blood alcohol level significantly at both 15 and 45 minutes after alcohol administration. (respectively, p<0.05) 3. Alcohol plus flurazepam, 30mg/kg of body weight daily for 5 days. In this group, there was also no significant change in the blood level at both 15 and 45 minutes after alcohol administration. (respectively, p>0.1) 4. Alcohol plus flurazepam, 30mg/kg of body weight daily for 10 days. In this group, flurazepam elevated the blood alcohol level significantly at both 15 and 45 minutes after alcohol administration. (respectively, p<0.01) Conclusion 1. Flurazepam, when administered orally in a dose of 15mg/kg of body weight daily for 5 days did not change the blood alcohol level significantly at both 15 and 45 minutes after alcohol administration. But, flurazepam, when administered orally in the same dose daily for 10 days, elevated the blood alcohol level significantly at both 15 and 45 minutes after alcohol administration. 2. Flurazepam when administered orally in a dose of 30mg/kg of body weight daily for 5 days did not change the blood alcohol level significantly at both 15 and 45 minutes after alcohol administration. But, flurazepam, when administered orally in the same dose daily for 10 days, elevated the blood alcohol level significantly at both 15 and 45 minutes after alcohol administration.

김치저장성을 향상시키기 위하여, Lactobacillus plantarum 용균효소 생산균주를 토양으로부터 분리한 후 그 효소를 정제하고 특성을 살펴보았다. 본 균주의 배양학적 및 형태학적 특성 등을 검토한 결과 Metarrisium anisopliae (Metschn). Sorok으로 동정되었으며, 본 효소는 affinity adsorption, CM-Sephadex C-50 column chromatography를 통하여 40%의 수율과 75배 정제도로 정제되었다. 효소활성의 최적 pH와 온도는 각각 4.0, 40℃였으며, pH 3.0~9.0, 60℃까지 효소의 안정성이 유지되었다. SDS-PAGE 및 gel filtration으로부터 본 효소의 분자량은 40,000 daltons인 monomeric protein임을 확인하였다. 본 효소는 Lactobacillus plantarum 세포벽 peptidoglycan의 peptide linkage를 절단 하는 endopeptidase였으며, 용균 spectrum으로부터 김치발효시 유용균인 Leuconostoc mesenteroides에 대해서는 활성을 거의 나타내지 않음을 확인할 수 있었다. 본 효소의 활성은 Ag^+, N-bromosuccinimide (NBS)에 의해서 완전히 저해되었으며, NBS에 의해서 활성이 저해된다는 사실로부터 본 효소는 활성에 tryptophan residue가 관여하는 것으로 확인되었다. 본 효소는 산성 아미노산의 함량이 염기성 아미노산의 함량에 비하여 높았으며, alanine, glycine, proline, tyrosine의 함량 또한 매우 높았다. To improve the preservation of Kimchi, we isolated Lactobacillus plantarum lytic enzyme-producing strain from soil, and the enzyme was purified and characterized. From the observation of cultural and morphological characteristics, the isolated strain was identified as Metarrisium anisopliae (Metschn). Sorok. The enzyme was purified to 75-folds with 40% yields through affinity adsorption and CM-Sephadex C-50 column chromatography. The optimum pH and temperature for lytic activity are 4.0 and 40℃, respectively, and the enzyme acitivity is stable between pH 3.0 and 9.0 and up to 50℃. The enzyme is a monomeric protein with molecular weight of 40,000 daltons by SDS-FAGE and gel filtration. The enzyme is endopeptidase which breaks the peptide linkage of Lactobacillus plantarum peptidoglycan. The lytic action spectra confirmed that Leuconostoc mesenteroides, a useful strain for the fermentation of Kimchi, is not lysed by the enzyme. The enzyme activity is inhibited by N-bromosuccinimide (NBS), which probably indicates the involvement of tryptophan residue in active site of the enzyme, and also inhibited by Ag^+. The amino acid composition analysis showed that the enzyme contains more acidic amino acids than basic ones, and composition of alanine, glycine, proline and tyrosines was very high.
