본 증례에서와 같이 BOOP는 임상상 및 조직소견에서의 특징과 좋은 예후를 갖는 미만성 침윤성 폐질환의 한 아형이며 원발성 폐섬유화증과는 달리 부신피질스테로이드에 의해 완치될 수 있다는 점에서 이 질환에 대한 인식은 매우 중요하다. 저자들은 부신피질스테로이드를 사용한후 1개월후부터 임상적으로 뚜렷한 호전을 보였으며, 2개월후부터는 흉부 X선 및 폐기능검사상 현저한 호전을 보였으며, 치료 3개월 후 부터는 prednisolne 요량 감소를 시작하였다. 경과도중 증상의 재발없이 일시적으로 흉부 X선상 새로운 병소가 나타났으나 용량을 증가시켜 곧 소실되었다. 치료 1년뒤 Prednisolone 중단 후에도 재발없이 안정상태를 유지하고 있다.

전국 결핵실태 조사에서 발견된 결핵환자와 보건소 또는 일반 병의원에서 진단된 환자 중 결핵치료 경험이 없는 환자로 부터 분리배양된 인형결핵균으로 각종 항결핵제에 대한 감수성검사를 실시한 결과 각약제에 대한 내성률은 그약제의 사용정도에 비례하고 그리고 전체 내성률은 결핵 치료효율과 역비례한다는 사실을 알 수 있었다. 1965년에 실시한 1차 결핵 실태조사에서 분리된 결핵률은 38.0%가 하나 또는 그이상의 약제에 대해 내성이었고 그후 다제(多濟)내성은 증가했지만 전체 내성률은 큰 변화가 없었다. 그러나 1980년에 내성률이 48.0%로 크게 증가했다. 이는 1980년 초에 평가한 보건소 결해 치료효율이 47%를 넘지 못한 것으로 보아 그동안 치료실패자의 누적이 있었기 때문인 것으로 추정된다. 그후 결핵치료 효율이 계속 중가하면서 내성률은 크게 감소하여 1985년에는 30.8%, 1990년에는 25.3%로 밝혀졌다. 초회내성률도 비슷한 변화추세를 보여주어 1965년에는 26.2%, 1970년에 23.9%, 1975년에 20.1%, 1980년에 30.6%, 1985년에 17.4% 그리고 1990년에 15.0%로 밝혀졌다. 보건소 또는 명의원 환자의 초회내성률도 이와 크게 다르지 않았다. 그리고 초회내성이 농촌 보다는 도시환자 가운데서 더 많았고 나이가 많은 환자 보다 적은 환자에서 더 많았다. 이상의 결과로 보아 약제내성률 조사가 결핵환자 치료관리의 효율성을 추구 평가하는데 매우 유용하다는 사실을 알 수 있다.

We report here an unusual case of pericardial tuberculoma that was misdiagnosed as thymic carcinoma on an imaging study. A 48-year-old woman was referred for evaluation of an anterior mediastinal mass. Computed tomography (CT) scans of the chest displayed cystic masses mimicking thymic carcinoma at the anterior mediastinum. Pericardiotomy and surgical drainage of the cystic masses were done, and pathologic examination of the excised pericardial specimen showed a chronic granulomatous inflammation with necrosis, compatible with tuberculosis. Acid-fast bacilli were also identified in the specimen. After treatment with anti-tuberculosis drugs and steroids, the patient showed clinical improvement. Although tuberculous pericarditis usually presents as pericardial effusion or constrictive pericarditis, it can also present as a pericardial mass mimicking thymic carcinoma on CT. Therefore, we suggest that tuberculous pericardial abscess should be included in the differential diagnosis of a mediastinal mass in Korea, with intermediate tuberculosis prevalence.

It is important to identify the most suitable anesthetic agent that has minimal side effects to be able to control and perform surgeries on bears. In this study, we examined and compared the induction and recovery times as well as the physiological changes occurring during anesthesia induced by medetomidine-zolazepam/tiletamine (MZT) and xylazine-zolazepam/tiletamine (XZT) at general anesthesia for laparoscopic salpingectomy in 326 female Asiatic black bears. The body temperature, heart rate, respiratory rate, and levels of PaO₂ and EtCO₂ were the physiological changes measured during surgical procedures in female bears after anesthesia. In addition, the levels of pO₂, pCO₂, and sO₂ were measured using a portable blood gas analyzer. To induce recovery from anesthesia, bears anesthetized with MZT were intravenously administered atipamezole and bears anesthetized with XZT were intravenously administered yohimbine. The combination MZT, at dosages of 0.019 ± 0.001 mg/kg for medetomidine and 1.4 ± 0.1 mg/kg for ZT, or the combination XZT, at dosages of 2.0 ± 0.1 mg/kg for xylazine and 3.0 ± 0.1 mg/kg for ZT, proved to be reliable and effective in anesthetizing Asiatic black bears for a 40-min handling period for routine clinical procedures. The average anesthesia induction times were 16.5 ± 0.95 min for the bears in the MZT group and 12.0 ± 0.44 min for those in the XZT group. A significant difference was noted between the two drugs (P < 0.001) in terms of the average anesthesia induction time. The anesthesia induction time was shorter for bears with lower body weights than those with higher body weights (P < 0.05). The recovery time of MZT was significantly faster than that of XZT (11.3 ± 0.45 min vs. 18.5 ± 0.83 min) (P < .001). The bears anesthetized with MZT exhibited lower cardiopulmonary suppression than those anesthetized with XZT (P < 0.05). The body temperatures and EtCO₂ of bears in the M ZT group were significantly lower than those in the XZT group as time progressed after anesthesia (P < 0.05). The average pO₂ before the bears were supplied with oxygen was 64.8 ± 3.7 mmHg, but it increased to 211.5 ± 42.5 mmHg afterwards (P < 0.001). In conclusion, our results indicate that bears anesthetized with MZT have longer anesthesia induction time, shorter recovery time, slower heart and respiratory rates, and lower body temperatures and EtCO₂ than those anesthetized with XZT. These findings suggest that XZT is preferable to MZT, warranting further research on its uses and clinical responses in bears.

Background: Intrapleural fibrinolytic therapy (IPFT) has been used as an effective agent since 1949 for managing complicated pleural effusion and empyema. Several agents, such as streptokinase, urokinase (UK), and recombinant tissue plasminogen activator (rt-PA), have been found to be effective with variable effectiveness. However, a head-tohead controlled trial comparing the efficacy of the most frequently used agents, i.e., UK and rt-PA (alteplase) for managing complicated pleural effusion has rarely been reported. Methods: A total of 50 patients were randomized in two intervention groups, i.e., UK and rt-PA. The dose of rt-PA was 10 mg, and that of UK was 1.0 lac units. UK was given thrice daily for 2 days, followed by clamping to allow the retainment of drugs in the pleural space for 2 hours. rt-PA was instilled into the pleural space twice daily for 2 days, and intercostal drainage was clamped for 1 hour. Results: A total of 50 patients were enrolled into the study, of which 84% (n=42) were males and 16% (n=8) were females. Among them, 30 (60%) patients received UK, and 20 (40%) patients received alteplase as IPFT agents. The percentage of mean±standard deviation changes in pleural opacity was -33.0%±9.9% in the UK group and -41.0%±14.9% in the alteplase group, respectively (p=0.014). Pain was the most common adverse side effect, occurring in 60% (n=18) of the patients in the UK group and in 40% (n=8) of the patients in the alteplase group (p=0.24), while fever was the second most common side effect. Patients who reported early (within 6 weeks of onset of symptoms) showed a greater response than those who reported late for the intervention. Conclusion: IPFT is a safe and effective option for managing complicated pleural effusion or empyema, and newer agents, such as alteplase, have greater efficacy and a similar adverse effect profile when compared with conventional agents, such as UK.

Objective: To study synergistic effects of nedaplatin and cisplatin on three human carcinoma cell lines (esophageal carcinoma cell line Eca-109, ovarian carcinoma Skov-3 and cervical carcinoma Hela). Methods: Inhibition effects were evaluated by MTT assay and cell apoptosis was detected by flow cytometry. In addition, changes of Ki-67, Bax and Bcl-2 at mRNA and protein levels were quantified by RT-PCR and Western blotting. Results: Growth inhibition in each cell lines was dose-dependent after exposure to nedaplatin or cisplatin alone. The interaction of the two drugs was synergistic at higher concentrations according to the median-effect principle. The inhibition rates with nedaplatin, cisplatin and combined treatment were $41.9{\pm}4.1%$, $47.4{\pm}2.9%$, $52.5{\pm}0.9%$(Eca-109), $39.0{\pm}1.26%$, $45.0{\pm}1.45%$, $56.2{\pm}1.44%$ (Skov-3) and $44.8{\pm}2.11%$, $46.9{\pm}0.99%$, $56.6{\pm}1.83%$ (Hela) respectively, with increase in apoptosis. Compared with the nedaplatin or cisplatin alone treatment group, the combinative treatment group's Ki-67 and bcl-2 mRNA (protein) expression was decreased while that of Bax mRNA (protein) was increased. Conclusion: Compared to the effects of nedaplatin or cisplatin alone at high concentrations, combination of nedaplatin and cisplatin at low concentrations proved to be much more effective for inhibition of proliferation and the induction of apoptosis in the Eca-109, Skov-3 and Hela cell lines.

Objective: To compare efficacy and safety profile of vinorelbine, ifosfamide and cisplatin (NIP) with etoposide and cisplatin (EP) in the treatment of advanced combined small cell lung cancer (c-SCLC). Methods: From January 2006 to December 2010, 176 patients with advanced c-SCLC were enrolled. The primary endpoint was overall survival (OS) and the secondary endpoints were progression free survival (PFS), response rate (RR) and toxicity. Results: Overall RR was 30.0% in the NIP and 38.5% in the EP group; there was no significant difference (P=0.236). The PFS in the EP group was little longer than that of NIP group, with 6.5 months for EP and 6.0 months for NIP group, but the difference was statistically non-significant (P=0.163). The median OS and one year survival rates were 10.4 months and 36.3% for NIP group, and 10.8 months and 49.0% for EP respectively, EP showing a survival benefit, although this was not statistically significant. Both groups well tolerated the adverse effects. The incidence of grade I-II leucopenia and alopecia in the NIP group was significantly higher than that of EP group (32.5% vs. 10.4% (P<0.001, 35.0% vs. 12.5%, P<0.001). Conclusion: the ORR, PFS and OS in NIP were slightly inferior to traditional regimen EP. The toxicity of NIP can be considered tolerable. The usage of three drugs combination in the treatment of mixed SCLC remains uncertain. Nevertheless, the results need to be further confirmed by large, prospective clinical trials.
