Fluconazole is used as an orally administrated antifungal drug for the treatment of tinea corporis, candidiasis including skin mycotic pneumonia infections. The dosage of fluconazole varies with indication ranging from 50 mg/day to 400 mg/day. The fluconazole capsule 50 mg (3 capsules daily) is already available in Korean market. To improve the patient compliance, a fluconazole tablet 150 mg (once a day administration) was developed recently. The purpose of this study was to evaluate the bioequivalence of three doses of fluconazole capsule 50 mg (Diflucan 50 mg, Pfizer Korea Inc., as a reference drug) and a single dose of fluconazole tablet 150 mg (Plunazol 150 mg, Daewoong Pharm. Co., Korea) according to the guidelines of the Korea Food and Drug Administration (KFDA). The bioequivalence for three capsules of Diflucan 50 mg and a single tablet of Plunazol 150 mg was investigated in twenty-four healthy male volunteers under a randomized 2${\times}$2 crossover trial design. The average age of twenty-four volunteers was 24.78${\pm}$3.27 year-old, average height was 175.56${\pm}$5.45 cm and average weight was 67.24${\pm}$6.86 kg. After three capsules of Diflucan 50 mg or a single tablet of Plunazol 150 mg were orally administered, blood was taken at predetermined time intervals and the plasma concentrations of fluconazole in plasma were determined using LC-MS-MS. The 90% confidence intervals for the main parameters of statistical results after logarithmic transformation were AUCt 0.9272-1.0084 and Cmax 0.8423-0.9544 respectively, which are in the range of log 0.8 to log 1.25 and the statistical results of additional parameters (AUClast, t1/2 and MRT) were also in the 90% confidence interval that is in the range of log 0.8 to log 1.25. Therefore, the results of this study confirm the bioequivalence of three capsules of Diflucan 50 mg to one tablet of Plunazol 150 mg.

라돈($^{222}Rn$)은 지각의 암석이나 토양 또는 건축자재 중에 들어 있는 우라늄($^{238}U$)과 토륨($^{232}Th$)이 몇 단계의 방사성붕괴과정을 거친 후 생성되는 무색무취의 불활성기체로 광산이나 지하같이 밀폐된 공간에 잘 축적된다. 호흡기를 통하여 폐로 유입되고 라돈의 딸핵종이 폐나 기관지에 침적되어 폐암을 일으키는 원인이 된다. 사람의 생명을 다루는 의료기관에서의 라돈피폭은 평상시 방사선피폭량이 많은 방사선관계종사자와 면역력이 약한 환자에게 큰 위험이 될 수 있다는 판단에 이 실험을 실시하였다. 실험에 쓰인 계측기는 실시간 라돈측정기인 Professional Continuous Radon monitor이며 계측장소는 두 개의 병원 지하1층에서 지상2층까지 층별로 오전 10시부터 오후 3시까지 측정 하였다. Professional Continuous Radon monitor계측결과는 최소 14.8 Bq/$m^3$에서 최대 70.3 Bq/$m^3$로 국내기준치인 148 Bq/$m^3$이하로 나타났으며 유효선량은 최소 0.296 mSv에서 최대 1.406 mSv로 일년간 자연방사선으로부터 피폭되는 방사선량인 2.4 mSv의 10~58.3% 수준으로 나타났다.

Purpose: To determine failure patterns and survival outcomes of T4N0-1 non-small cell lung cancer (NSCLC) treated with definitive radiotherapy. Materials and Methods: Ninety-five patients with T4N0-1 NSCLC who received definitive radiotherapy with or without chemotherapy from May 2003 to October 2014 were retrospectively reviewed. The standard radiotherapy scheme was 66 Gy in 30 fractions. The main concurrent chemotherapy regimen was $50mg/m^2$ weekly paclitaxel combined with $20mg/m^2$ cisplatin or AUC 2 carboplatin. The primary outcome was overall survival (OS). Secondary outcomes were failure patterns and toxicities. Results: The median age was 64 years (range, 34 to 90 years). Eighty-eight percent of patients (n = 84) had an Eastern Cooperative Oncology Group performance status of 0-1, and 42% (n = 40) experienced pretreatment weight loss. Sixty percent of patients (n = 57) had no metastatic regional lymph nodes. The median radiation dose was EQD2 67.1 Gy (range, 56.9 to 83.3 Gy). Seventy-one patients (75%) were treated with concurrent chemotherapy; of these, 13 were also administered neoadjuvant chemotherapy. At a median follow-up of 21 months (range, 1 to 102 months), 3-year OS was 44%. The 3-year cumulative incidences of local recurrence and distant recurrence were 48.8% and 36.3%, respectively. Pretreatment weight loss and combined chemotherapy were significant factors for OS. Acute esophagitis over grade 3 occurred in three patients and grade 3 chronic esophagitis occurred in one patient. There was no grade 3-4 radiation pneumonitis. Conclusion: Definitive radiotherapy for T4N0-1 NSCLC results in favorable survival with acceptable toxicity rates. Local recurrence is the major recurrence pattern. Intensity modulated radiotherapy and radio-sensitizing agents would be needed to improve local tumor control.

Purpose: Neoadjuvant chemotherapy has been shown to improve survival in locally advanced gastric cancer, but it is associated with significant toxicity. Sarcopenia and sarcopenic obesity have been studied in several types of cancers and have been reported to be associated with higher chemotherapy toxicity and morbi-mortality. The aim of this study was to assess the prevalence of sarcopenia/sarcopenic obesity in patients with gastric cancer, as well as its association with chemotherapy toxicity and long-term outcomes. Materials and Methods: A retrospective analysis was performed using an academic cancer center patient cohort diagnosed with locally advanced gastric cancer between January 2012 and December 2014 and treated with neoadjuvant chemotherapy. We analyzed body composition (skeletal muscle and visceral fat index) in axial computed tomography images. Results: A total of 48 patients met the inclusion criteria. The mean age was $68{\pm}10years$, and 33 patients (69%) were men. Dose-limiting toxicity was observed in 22 patients (46%), and treatment was terminated early owing to toxicity in 17 patients (35%). Median follow-up was 17 months. Sarcopenia and sarcopenic obesity were found at diagnosis in 23% and 10% of patients, respectively. We observed an association between termination of chemotherapy and both sarcopenia (P=0.069) and sarcopenic obesity (P=0.004). On multivariate analysis, the odds of treatment termination were higher in patients with sarcopenia (odds ratio=4.23; P=0.050). Patients with sarcopenic obesity showed lower overall survival (median survival of 6 months [95% confidence interval {CI}=3.9-8.5] vs. 25 months [95% CI=20.2-38.2]; log-rank test P=0.000). Conclusions: Sarcopenia and sarcopenic obesity were associated with early termination of neoadjuvant chemotherapy in patients with gastric cancer; additionally, sarcopenic obesity was associated with poor survival.

The $^{99m}Tc$-pertechnetate thyroid uptake rates(20 min) were measured in 24 healthy normal subjects, 140 patients with nontoxic goiter and 98 patients with thyrotoxicosis who were treated at the Thyroid Clinic, Seoul National University Hospital, from August 1972 to August 1973. Diagnostic reliabilities and correlations between $^{99m}TcO_4$-thyroid uptake rate (20 min) and other thyroid function tests were evaluated. The observed results were as follows 1. The $^{99m}TcO_4$-thyroid uptake rates (20 min) in normal subjects, euthyroid group and hyperthyroid group were $4.1{\pm}0.9%,\;5.2{\pm}1.8%\;and\;29.7{\pm}10.6%$. There was a significant difference between the mean of the euthyroid group and the mean of the hyperthyroid group and so differentiation between them can be easy. 2. In the diagnosis of hyperthyroidism, the reliabilities of $^{99m}TcO_4$- thyroid uptake rate(20 min), $^{131}I$ thyroid uptake rate(24hrs), serum $T_3$ resin uptake rate, serum $T_4\;and\;T_7\;were\;87.9{\sim}97.9%,\;81.2{\sim}94.4%,\;87.9{\sim}97.9%,\;90.5{\sim}99.3%\;and\;93.7{\sim}100%$. $^{99m}TcO_4$-thyroid uptake rate(20 min) is more accurate than $^{131}I$ thyroid uptake rate (24 hrs) in the diagnosis of hyperthyroidism. 3. $^{99m}TcO_4$-thyroid uptake rate (20 min) was well correlated with $^{131}I$ thyroid uptake rate (24 hrs), serum $T_3$ resin uptake rate, serum $T_4\;and\;T_7$. Points in favor of $^{99m}Tc$ are that it gives a small radiation dose to the thyroid, that tests can be repeated at the short interval, the study can be completed at a single patient visit and it is particularly well suited for the assessment of thyroid function in patients being treated with an antithyroid drug.

This study was performed to investigate the effect of peroxisome proliferators activated receptor-${\gamma}$ (PPAR-${\gamma}$) ligand, pioglitazone, on production of regulated upon activation normal T-cell expressed and secreted (RANTES) and in vitro fertilization (IVF) outcome in infertile patients with endometriosis. Sixty-four infertile patients with stage III or IV endometriosis undergoing IVF were randomly allocated to the study or the control group. The long protocol of GnRH agonist (GnRH-a) was used for controlled ovarian stimulation (COS) in all patients. Patients in the study group were treated with pioglitazone at a dose of 15 mg/day orally from the starting day of GnRH-a treatment to the day of hCG injection. Blood samples were drawn for serologic assay of RANTES on the first day of GnRH-a treatment and the day of hCG injection. There were no differences between the study and control groups in patient characteristics. There were also no differences between the two groups in COS duration, and the numbers of retrieved oocytes, fertilized oocytes and embryos transferred. The clinical pregnancy rate per cycle was higher in the study group, but this difference was not statistically significant. However, embryo implantation rate was significantly higher in the study group of 12.5% compared with 8.6% in the control group (P<0.05). The serum RANTES levels after pioglitazone treatment were significantly lower than those before pioglitazone treatmen in the study group (P<0.05). Our data suggest that pioglitazone treatment can suppress RANTES production and improve the embryo implantation rate in patients with endometriosis undergoing IVF.

Clozapine은 정형적 항정신병약물에 반응하지 않는 불응성 정신분열증 환자에게 효과적이며, 추체외로부작용이 적은 비정형적 향정신병약물로 보고되고있다. 따라서 저자들은 불응성 정신분열증환자를 대상으로 clozapine의 항정신병효과 및 부좌용에 대해 대표적 전형적 항정신병약물인 haloperidol과 비교연구하였다. 대상환자를 clozapine투여군(17명) 과 haloperidol 투여군 (16명)으로 나누어 12주 동안 각각의 약물을 투여하는 전향적 개방대조연구를 하였다. 두가지 약물의 치료효과와 부작용은 BPRS, PANSS, Simpson-Angus Rating Scale 및 Adverse Events-Somatic Symptoms를 사용하여 평가하였다. 약물투여 12주후 clozapine투여군이 76.5% 에서 치료반응을 보인데 비해 haloperidol투여군은 31.2%의 치료반응을 보임으로써 두약물 투여군간에 유의한 차이가 있었다. BPRS와 PANSS 척도상 clozapine투여군이 haloperidol투여군에 비하여 BPRS, PANSS 양성증상 및 일반증상 척도는 약물투여 8주후부터, PANSS 음성척도는 약물투여 4주후부터 12주까지 일관성있게 지속적으로 의미있는 호전을 보였다. Clozapine투여군에서는 타액분비(70.6%), 졸리움(52.9%), 변비(29.4%) 및 저혈압(23.4%)이, haloperidol투여군은 진전(37.5%), 정좌불능(25.0%), 강직(18.8%) 및 무운동(18.8%)이 흔히 보고되었다. 하지만 두약물 투여군 모두에서 대부분 경미하고 환자가 견딜 정도였다. Clozapine투여군에서 약물투여 전에 비해서 약물투여 12주후 백혈구와 호중구의 유의한 변화는 없었다. 이상의 결과를 종합해볼 때, clozapine은 정형적 항정신병약물에 치료효과가 없거나 추체외로부작용 때문에 약물투여가 어려운 경우의 한국인 불응성 정신분열증환자에게 효과적인 비정형적 항정신병약물이다.

Background: Ma-huang (Ephedra sinica) has been widely used to treat respiratory disease in oriental medicine for over a hundred years. Ma-huang preparations contain approximately 1.25% ephedrine alkaloids. Recently, the ephedra alkaloids have received much press lately due to adverse effects in those using whole extracts as 'dietary supplements' for weight loss or athletic performance enhancement, and these reports are troubling given the increasing use of Ma-huang by the general public. The purpose of this report is to determine the proper dosage to minimize adverse effects and maximize the potential curative value. Objectives : The object of this study was to find an effective yet low risk dosage of Ma-huang. Methods : The study was designed as a double-blind randomized placebo-controlled trial. The subjects of this study were 26 adults between 20 to 40 of age who agreed to participate in this study. They were allocated through randomization into three groups. Each group took three opaque capsules three times a day. A group (N=9) took one Ma-huang capsule and two placebo capsules, B group (N=8) took two Ma-huang capsules and one placebo capsule, C group (N=9) took three Ma-huang capsules. The total trial periods was two days. To compare the adverse effects of Ma-huang according to dosage, blood pressure and pulse were checked, and other adverse effects were assessed using a morning questionnaire, patient's global assessment scale and Wong-Baker faces pain rating. Results : The following result were obtained: 1. After taking 18 g of Ma-huang per day, pulse rate had a significant increase. 2. After taking more than 6 g of Ma-huang per day, palpitation would be increased significantly. 3. After taking more than 18 g of Ma-huang per day, tiredness would be increased significantly. Conclusion: According to the results, 12 g of Ma-huang per day will minimize adverse effects and maximize the potential curative value.
