백색부후균 Trametes versicolor(CV5) 균주에 의한 wood lignin의 분해능을 조사하였다. CV5는 활엽수와 침엽수에 속하는 여러 수종의 프로토 리그닌 분해 시 활엽수에 한해서 분해되는 특성을 보였으며, 특히 상수리나무에서 33.5%의 가장 높은 리그닌이 분해되었다. 리그닌 분해에 관련된 phenoloxidase 분비능을 Bavendamm 시험을 통해 검토한 결과 CV5는 지금까지 연구된 우수 백색 부후균과 같은 유사 반응 형태를 나타내고 있음을 확인하였다. 또한 상수리 목재 chip표면에 CV5의 균사가 생육하면서 목재조직이 부후된 상태를 주사전자 현미경으로 관찰한 결과 목섬유 및 도관에서 균사의 침투와 목재조직의 분해를 확인하고 리그닌에 대한 높은 선택적 분해력을 갖고 있음을 구명하였다. Trametes versicolor(CV5) selected as a white-rot fungus with strong lignin degrading activity, in the previous paper, was investigated on a properties of degradation of wood lignin. Lignins of hardwoods, especially oak(Querous acutissima carruth) an paulownia (Paulownia coreana Uyeki) were considerably delignified by the CV5, however, softwoods used in this experiment were not delignified. Bavendamm's reaction was positive with several phenols on agar plates for the confirmation of a phenoloxidase secreted Through the morphologies of decayed wood chip observed with the aid of scanning electron microscopy, it was found that the hypha of CV5 penetrated the ray cells and vessels caused separation of the wood cellulose.

Graft-versus-host disease (GVHD) is a frequent complication after bone marrow transplantation. Infectious complications are common in GVHD patients due to defect in cell-mediated immunity. A rare case of S. pneumoniae meningoencephalitis occured in a patient with extensive form of chronic GVHD after allogeneic bone marrow transplantation. He was immediately treated with full dosage of ceftriaxone and ampicillin. He suffered from various complications such as sepsis, acute renal failure, atelectasis, and seizure. Despite of aggressive treatment, he died probably due to renal shutdown and massive subacute cerebral infarction of left cerebral hemisphere. This report showed two unusual and rare features. First, the infection site was CNS rather than respiratory system. Second, the causative organism was S. pneumoniae, which is rare cause of CNS infection in immunocompromised patients.

林漢鍾,張維臣 고려대학교 의과대학 1980 고려대 의대 잡지 Vol.17 No.1

Since 1961 bithionol has been extensively for the treatment of paragonimiasis westermani and it was proved as a drug of choice for the paragonimiasis caused by all kinds of Paragonimus. However, the multiple doses and it's side reactions are hampered in mass treatment with bithionol in the field. In the present study, two new drugs, niclofolan and praziqunatel, were attempted to the clinical trials for the treatment of paragonimiasis. The disappearance of eggs and chest X-ray improvement as well as the disappearance of clinical symptoms served as criteria for evaluating the therapeutic effects of the two drugs were compared. A total number of 40 paragonimiasis cases were treated with niclofolan at a single dose of 2.0㎎/㎏ body weight. The eggs in sputa of all cases except two were disappeared after one month of the medication and never relapsed during the follow up period, but in 2 cases the eggs were found in their sputa from the results of the follow up investigations. Therefore, the cure rate was shown as 95.0 percent. On the other hand, 50 paragonimiasis cases were treated with praziquantel at the dosages of 3×25㎎/㎏ bwt in a single day, 2 days and 3 days. 15 out of 21 cases who received 3×25㎎/㎏ bwt in a single day shoed negative eggs in their sputa or stools during the follow up period of 4 months after medication. The cure rate was 71.4 percent. In 19 cases who received 3×25㎎/㎏ bwt for 2 days, all cases except two showed complete negative egg in the follow up study. The cure rate was shown as 89.5 percent. However, in 10 cases received 3×25㎎/㎏ bwt for 3days, complete cureness was obtained at the follow up examinations. The treatment with niclofolan and praziquantel were found to be highly effective in pulmonary paragonimiasis. In treated cases disappearance of eggs and clinical symptoms were observed after one month of the mediation, and regressions in size of the lesions by chest X way finding were reviewed within 4 months after treatment. The laboratory tests were performed before and immediately after treatment in order to study for the drug influences on hematology, blood biochemistry and urnalysis. In some cases who received niclofolan, a transient marginal or slight rise of SGOT, SGPT, and BUN levels were seen, but no toxic nor abnormal effects were revealed. Adverse reactions consisted mainly muscle tenderness at the sacro-iliac region and the extremities, sweating and lassitude. But none of these symptoms was so severe to require bed-rest or withdrawal of the drug. On the other hand, none of the causes with laboratory abnormalities and unwanted side effects attributable to praziquantel were observed. Consequently both niclofolan and praziquantel are highly effective for the treatment of paragonimiasis, but praziquantel is more effective and safe drug than niclofolan. Therefore, praziquantel is the most promising drug for the treatment of paragonimiasis as well as clonorchiasis.

외국산 양주의 진위를 판정하는 방법을 수립하기 위하여 GC를 이용해서 71종의 표준양주에 함유되어 있는 ethyl acetate와 3종류의 고급 알코올, 즉n-propanol, iso-butanol,iso amyl alchol의 함량을 측정하고, 각양주의 UV최애흡수파장과 흡광도를 측정하여 외국산 양주의 진위판정 기준으로 이용하였다.이와 같은 기준에 의하여 가짜로 의심되는 3종류의 양주를 분석한 결과 다음과 같은 판정ㅇ 가능하였다. 1종은 저급의 외국산 양주가 고급 외국산 양주고 위조된 것이고, 2종은 국산양주가 외국산 양주로 위조된 것으로 판명되었다. This study attempts to establish the methods to evaluate adulterated foreign liquors, we anlized the content of ethyl acetate, n-propanol, iso-butanol and iso-amyl alcohol in 578 reliable and 3 unreliable foriegn liquors and 14 Korean liquors by gas chromatography. Subsequently, UV absorption maximum wavelengh and optical desity of these liquors were measured. These contents of the 3 unreliable foreign liquors were compared with the contents of the reliable liquors. The results were as follows: 1.The Jack Daniels(Old No.7)of foreign bourbon whisky was adultesated to Cammus(VSOP)of foreign cognac brandy. 2.The Captain Q spirit made in Korea was adultesated to Chivas Regal(12 years) of foreign scotch whisky. 3.The Old of spirit made in Korea was adultesated to Johnnie Walker(Black Label, 12 years) of foreign scotch whisky. Therefore reliability if foreign liquor could be decided by teh content of ethyl acetate and higher alchols the measurment fo UV absorption maximum wavelengh and optical density in liquors.

Background and Objectives : Palindromic rheumatism (PR) is known to be triggered without any obviously inciting events in most patients, although, in a few cases, attacks have been noted to relate to another events such as weather change, childbirth, ingestion of certain foods, or over-exercise. The aim of this study was to characterize the triggering factors on palindromic attacks. Materials and Methods : We evaluated sixty-four patients with PR for the presence of triggering factors and the relationship between attacks and triggering factors by interview of patients. We considered that there was an probable association between episodes and PR, if episodes within 24 hours prior to PR had triggered at least 50% of all attacks and a definite association between episodes and PR, if episodes within 24 hours prior to PR had triggered 100% of all attacks. Results : In 15 patients (35.9%), there was a possible association between episodes of PR and initiating events. In 8 patients (12.5%), there was a definite association between episodes of PR and initiating events. The triggering factors were physical over-activity including exercise (19/64: 29.7%), foods, such as rawfish, crab, and chicken, including alcohol (19/96: 19.8%). However, there were no difference between the groups with and without the triggering factor in sex ratio, duration and onset of PR, the positive rate of rheumatoid factor and involved sites. Conclusion : Our observations showed that PR was triggered by physical over-activity more than in previous reports and hypersensitivity to foods was a causative factor in some patients with PR. However, patients with triggering factors had a similiar clinical profile to patients without triggering factors.
