This study was undertaken to investigate the efficacy of 5% PABA cream using mouse ear swelling reaction(ESR). Mice were exposed to 100mJ/cm of UVB, five times a week for four weeks, on the both ventral aspect of the ear, with application of 5% PABA cream on the right ear. The results were as follows : 1. The intensity of ear swelling reaction of 5% PABA protected group was reduced greater than unproteeted group after the first 3 days of UUR. 2. The intensity of ear swelling reached at peak after 1 week of the ultraviolet radiation. Thereafter it has decreased gradually the following 4 weeks. The difference of ear swelling between the two groups was the greatest after 1 week, and the sunscreening efficacy of 5% PABA cream has remained persisted for 4 weeks. 3. The number of mice which have shown severe inflarnmatory response after ultravioiet radiation was more in unprotected group than that in 5% PABA protected group. 4. Determination of mouse ESR is considered a good method for the evaluation of longterm efficacy of sunscreen preparation.

Clothing dermatitis is a rare disease. The distribution of the eruption coincides with the places on the skin where the garment fits most snugly. It is developed by the chemicals and the dyes rather than textile itself. We experienced 2 cases of clothing dermatitis, one of which was caused by formaldehyde in clothing.

Objectives: The purpose of this study was to develop a screening tool that is simple and easy to use for assessing sleep problems, including hypersomnolence, restless legs syndrome, and insomnia. We also examined the reliability and validity of this tool. Methods: We developed the Sleep Problem Screening Questionnaire (SPSQ), which consists of three sub-sections: insomnia (SPSQi), hypersomnolence (SPSQh), and restless legs syndrome (SPSQr). Subsequently, the participants, consisting of 222 patients with insomnia disorder and 78 healthy individuals, completed both the SPSQ and the comparative scale (Korean version of the Insomnia Severity Index). The analysis was then conducted using this data. Results: The SPSQ demonstrated good convergent and discriminant validity, as well as satisfactory internal consistency. A cutoff score of 6 on the SPSQi was found to be optimal for distinguishing individuals with insomnia. Conclusion The results of this study suggest that the SPSQ is a reliable and valid tool for screening sleep problems among general adult population. However, there is a limitation as a comparison and validation with scales related to restless legs syndrome and hypersomnolence were not conducted.

This study was conducted to assess the health risk on the volatile organic compounds such as toluene, xylene, and styrene in painting workplace. It was monitored through personal air sampling during working time in selected 5 workplaces and analysed using gas chromatography. For the settlement of exposure situation, there were regarded working conditions such as working hours, yearly working days, and working years. Also, Monte-Carlo simulation was used for the induction of hazard index using toxicity value from IRIS(Integrated risk information system) database. The results of risk assessment were summarized as follows : 1. The air concentration of toluene was 7.096+/-15.6 ppm, 2.586+/-4.2 ppm for xylene, 1.914+/-5.3 ppm for styrene in blast painting workplaces. The level of toluene was different significantly compared with the level of xylene and styrene. 2. Computated chronic daily intake value of 95th percentile on toluene, xylene and styrene treated by Monte-Carlo simulation were 9.616, 3.567, 2.782 mg/kg/day, respectively. 3. Computated hazard index value of 75th percentile on toluene, xylene and styrene treated by Monte-Carlo simulation were 3.5, 1.0 and 1.6, respectively. Adverse health effects on the toluene, xylene and styrene would be expected by working exposure in blast painting workplace since the hazard indices of three compounds were exceeded 1 in the surroundings of percenitile 75 through having the low emerged frequency

Objectives: This study developed a battery test that allows a comprehensive evaluation of depressive symptoms and related protective-vulnerable factors to screen for depression and mental health and examined the reliability and validity of the test. Methods: PROtective and Vulnerable factors battEry test (PROVE) consisting of five sub-sections was developed: depressive symptomatology (PROVE-DS), suicide risk (PROVE-SR), and three protective-vulnerable factors, which were adult attachment type (PROVE-ATT), adverse childhood experience (PROVE-ACE), and mentalization capacity (PROVE-MC). Two hundred and thirteen subjects completed the PROVE test and other comparative scales, and the analysis was carried out based on the data. Results: The PROVE test showed good convergent, discriminant, and concurrent validity as well as adequate internal consistency. In addition, five sub-sections of the PROVE test showed significant relevance to each other. Conclusion The results of this study indicate that the PROVE test is a reliable and valid test, which will be useful for the prevention, evaluation, and treatment of depression in various clinical settings.

Lung toxicity associated with cyclophosphamide use is a rare but serious side effect, that may result in a fatal course. However no such cases have been reported in Korea, so clinicians would not be alert to this adverse effect. We recently experienced a woman with Wegener's granulomatosis and idiopathic pulmonary fibrosis. This patient had been administered 12 grams of cyclophosphamide for 4 months. At that time of admission, She felt aggravating dyspnea on exertion for 2 weeks. Her chest x-ray and high resolution CT revealed aggravated reticular opacities and ground glass appearances. Dyspnea was improved and ground glass appearances on HRCT was disappeared after discontinuation of cyclophosphamide. We diagnosed this case as cyclophosphamide-induced pneumonitis and report it with a brief review of the literature.

OBJECTIVES: Protein-calorie malnutrition is a common problem in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). Serum albumin(SA) concentration has been used as a marker for assessing nutritional status. Hypoalbuminemia has been linked to an increased risk of morbidity and mortality and more numerous, prolonged hospitalization for peritoneal dialysis patients. The aim of this study was to determine factors affecting SA value in CAPD patients. METHODS: We performed a cross-sectional study which included patients' demographics, anthropometric data, biochemical parameters, urea kinetic data and comorbidity in 106 stable CAPD patients. RESULTS: 1) There were 50 men and 56 women with a mean CAPD duration of 43 months and mean age of 49 years. The mean concentration of SA was 3.9+/-0.5 (range 2.5-5.3) g/dl and weekly Kt/Vurea 2.0+/-0.4 (range 1.32-3.79) 2) Twenty-one patients(20%) were classified as group I(SA<3.5g/dl)and the remaining patients(80%) as group II(SA 3.5g/dl) 3) Group I patients were significantly older(55+/-11 vs 47+/-11 years, p<0.05) and had significantly higher comorbidity score(1.5+/-0.8 vs 0.7+/-0.9, p<0.05), C-reactive protein (4.5+/-0.9 vs 0.5+/-0.1 mg/dl, p<0.05), 24-hr dialysate-toplasma creatinine(D/PCr) ratio(0.84+/-0.1 vs 0.76+/-0.1, p<0.05), 24-hr dialysate protein (7167+/-2031 vs 5471+/-1515 mg, p<0.05) and had significantly lower residual renal function(RRF)(0.2+/-0.3 vs 0.7+/-1.2 ml/min, p<0.05), BUN(48+/-14.8 vs 55.6+/-14.9 mg/dl, p<0.05), serum creatinine(10.4+/-2.8 vs 12.6+/-3.5 mg/dl, p<0.05), IGF-1(186+/-99 vs 260+/-131 ng/ml, p<0.05), serum phosphorus(4.1+/-1.2 vs 5.0+/-1.3 mg /dl, p<0.05) than group II.4) SA showed positive correlation with anion gap (r=0.43, p value=0.001), transferrin(r=0.41, p value= 0.001) phosphorus(r=0.31, p value=0.001) and negative correlation with 24-hr dialysate protein loss(r=-0.51, p value=0.001), 24-hr D/PCr ratio(r=-0.49, p value=0.001), comorbidity score(r=-0.36, p vluue=0.001). NPCR(r=0.22, p value=0.023), IGF-1(r=0.30, p value=0.002), BUN(r=0.23, p value=0.016) weakly correlated with SA.5) By stepwise multiple logistic regression analysis, age, CRP, 24-hr D/PCr ratio and RRF independently influenced SA level. CONCLUSION: SA level seems to be affected by non-nutritional factors such as age, peritoneal membrane transport characteristics, residual renal function and presence of acute phase protein response manifested by CRP elevation, in addition to nutritional factors.
