Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

Pseudomembranous colitis, caused by altering the normal colonic flora and allowing the multiplication of Clostridium difficile, is an deleterious adverse effect of antibiotics. But it is rarely reported by rifampicin. Rifampicin is one of the first line drug in the treatment of tuberculosis and many patients are exposed to its potential adverse effects. We experienced a patient that had abdominal discomfort and hematochezia due to pseudomembranous colitis after receiving antituberculous medication, and which was probably caused by rifampicin. A 82 years old man was admitted with abdominal discomfort and hematochezia for one week. On the past history he had been diagnosed as endobronchial tuberculosis about 4 months ago. Colonoscopy revealed multiple discrete whitish mucosal lesion on rectosigmoid colon, and histologic findings were consistent with pseudomembranous colitis. The antituberculous agents were discontinued and vancomycin was administered. The patient's symptoms were resolved within several days. There was no recurrence after reinstitution of the antituberculous agents excluding rifampicin. We report here on a case of pseudomembranous colitis probably due to rifampicin.

Background: Progastrin-releasing peptide (proGRP) is a recently identified biomarker of small cell lung cancer (SCLC). We aimed this study for evaluating the usefulness of automated proGRP measurement for diagnosis and treatment monitoring in patients with SCLC. Methods: From January 2011 to December 2013, plasma samples were prospectively collected from 452 [213 non-small cell lung cancer (NSCLC), 104 SCLC, 135 other diseases] patients visited for tissue diagnosis and tested by two-step automated immunoassay using the ARCHITECT proGRP assay kit (Abbott Diagnostics, USA). The cutoff level of proGRP was set at 63 pg/mL. Results: The mean proGRP was higher in SCLC (1823.0 ± 2684.0 pg/mL) than in NSCLC (61.0 ± 341.7 pg/mL) and other diseases (51.5 ± 222.6 pg/mL, p<0.001). The sensitivity of proGRP was 85.7% (90/105) in SCLC and 11.8% (25/212) in NSCLC. The specificity was 90.2%, positive predictive value was 72.5%, and negative predictive value was 95.4% in SCLC. The mean proGRP was higher in extensive disease (2158.1 ± 2980.6 pg/mL) than in limited disease (901.4 ± 1216.0 pg/mL, p=0.033). Among the 39 patients with SCLC could be followed, the mean proGRP levels of 23 responders were significantly decreased after chemotherapy (from 1651.5 ± 1386.4 pg/mL to 290.0 ± 524.8 pg/mL, p<0.001), whereas those of the 16 non-responders were not. (from 572.5 ± 790.3 pg/mL to 494.4 ± 610.9 pg/mL, p=0.583). Conclusion: Plasma proGRP could be a useful biomarker of SCLC for diagnosis and treatment monitoring. And the initial level may represent the tumor extent of SCLC.

金洙賢,鄭昌朝,趙韓玉,金在河 제주대학교 방사능이용연구소 1985 연구보고 Vol.1 No.-

濟州産 鹽乾옥돔(yellow sea bream ; Branchiostegus japonicus japonicus)을 Vinyl 眞空包裝 0, 0.5, 1.0, 1.5 및 2.0Mrad 水準으로 放射線 照射후 室溫과 冷藏으로 60日間 貯藏하여 鹽乾옥돔의 理化學的變化 및 官能檢査를 수행하였다. 貯藏期間中 總菌數는 放射線 照射水準이 높아짐에 따라 抑制되고 있었으며, 放射線照射와 冷藏處理가 더욱 效果的이었다. TMA의 增加率은 高線量水準에서 적었으며 2.0Mrad水準은 도리어 貯藏初期에 비하여 末期에 이르러 TMA의 含量을 減少시켰다. TMAO의 減少率은 貯藏條件에 관계없이 照射後 20日傾부터는 急激한 減少現象을 나타내었다. Total nitrogen의 減少는 無照射區에서 가장 컸으며, 照射水準이 높아짐에 따라 變化의 폭은 적었다. VBN含量은 各 處理區 모두 D30에서 顯著한 增加를 보이고 있었으며, 放射線處理에 따라 多少 抑制되었다. 放射線照査와 室溫貯藏區에서는 20日까지, 放射線照査 및 冷藏處理區에서는 40日까지 鹽乾옥돔의 鮮度를 유지시킬 수가 있었다. 組織變化, 總菌數, 腐敗 등 要因을 考慮할 때 鹽乾옥돔의 貯藏性向上을 위해서는 1.0Mrad가 適正水準으로 推定되었다. Salted dry yellow sea bream were vaccum packed in a plastic bags and irradiated at differents levels (0.0.5, 1.0, 1.5 and 20 Mrad) using ?? source. The irradiated samples were stored at room temperature and 5℃. Physical and chemical properties were examined during storage. The total bacterial count was depressed according to level of irradiation applied. It was noted that cold storage after irrdiation was more effective than room temperature. TMA contents slowly increased with higher dosage rates up to 1.5 Mrad but there was a gradual decrease of TMA at the 2.0 Mrad level.It was observed that there was a rapid decrease of TMAO 20 days after irradiation irrespective of storage temperature. The reduction of total nitrogen content was highest in the control but to a lesser degree when irradiation was applied. VBN content increased in all treatments 30 days after irradiation but it was also noted that there was a tendency toward depression of VBN by irradiation. The shelf life of salted dry sea bream was extended by 20 days with irradiation plus room temperature, and by 40 days with irradiation plus cold storage. To extend shelf life of salted dry sea bream, the most effective dosage rate was 1.0 Mrad based on tenderness, bacterial count and rancidity.

In order to verify the occurrence of an estrogenic compound in products of pomegranate extract, the estrogen-like activities were measured using an in vitro detection system. For this system, human breast cancer cell line MCF7 was transfected using an estrogen responsive CAT reporter plasmid. Estrogen-like activities of pomegranate extracts were evaluated using this system. Estrogen-like activity of a 500 μg/ml sample of pomegranate extract 1 was between those of 10^(-7) M and 10^(-9) M standard solution (17β-estradiol) and activity of 50 μg/ml sample of pomegranate extract 1 was as much as that of 10^(-9) M standard solution. Estrogen-like activity of a 500 μg/ml sample of pomegranate extract 2 was stronger than that of 10^(-7)M standard solution (17β-estradiol) and activity of 50 μg/ml sample of pomegranate extract 2 was as much as that of 10^(-7) M standard solution.

Renal papillary necrosis occurs most commonly in association with urinary tract infection, diabetes mellitus, sickle cell disease, vascular disease, and analgesic nephropathy. Clinical presentation may be related to symptoms of pyelonephritis such as flank pain, renal colic, hematuria, Proteinuria, recurrent fever. The necrotic tissue may be sloughed off, and the diagnosis can sometimes be made by finding piece of renal medullary tissue in the urine. Pyelography may demonstrate cavities and sinuses in the resion of papillae. Anuria & oliguria can lead to the acute renal failure, and especially prognosis and progress may be affect influenced by urinary infection. We report a case of renal papillary necrosis with ingestion of bear gallbladder. On pyelography, Persistent contrast is diagnostic clue of renal papillary necrosis. This case is not be related to urinary tract infection, but occurred acute renal failure. Expectant treatment was gone.
