PURPOSE: The purpose of this study was to identify the relationship of job stress, depression and to identify factors influencing suicide ideation of women-workers. METHODS: The research was a cross-sectional, descriptive study. Data collection was done using self-report questionnaires with 348 women-workers who agreed to participate in the study. Data were analyzed using descriptive statistics, t-test, chi2-test, logistic regression analysis by using SPSS/WIN 18.0. RESULTS: The results showed, among the independent variables, drinking, job stress, depression are significant factors that influence women-workers' suicide ideation. Women-workers' depression is 3.05 times higher (p<.002), and job stress 1.03 times higher suicide ideation (p<.045), and drinking 2.15 times higher suicidal ideation (p<.006). CONCLUSION: The results indicate that suicide ideation is highly prevalent in women-workers, especially among people with depression and job stress. It is necessary to seek how to prevent and manage womenworkers' suicide ideation considering features.

PURPOSE: In adriamycin(ADR)-induced cardiomyopathy, several different mechanisms are suggested. However, little information is available regarding the role of apoptosis. In the present study, we examined the induction of apoptosis on ADR treatment and anti-apoptotic effects of probucol, a lipid-lowering drug, and we also studied the changes of bcl-2 expression in order to see the molecular mechanisms underlying the effect of probucol. METHODS: Cardiac myocytes were isolated from 3-day-old rats, and cultured in low(1 pM) or high doses(10pM) of ADR for 24 hours. Probucol(50 pM) was added 30 minutes before ADR administration. Apoptosis was determined by TUNEL staining, and bcl-2 expression was estimated by immunocytochemistry. RESULTS: The number of TUNEL-positive cells significantly increased in both groups treated with ADR. However, anti-apoptotic effect of probucol was evident only in low dose. In addition, the expression of bcl-2 was significantly increased only in the low-dose ADR treatment group and its expression was inhibited by pretreatment of probucol. CONCLUSION: These results suggest that apoptosis might play an important role in ADR-induced cardiotoxicity, and ADR-induced apoptosis was partially prevented by pretreatment of probucol. And ADR-induced apoptosis was not related with depression of bcl-2. Additionally, inhibition of bcl-2 gene expression of low-dose ADR treatment group by probucol suggests that another cell survival mechanism could be implicated in the action of probucol.

PURPOSE:Cardiovascular morbidity has recently been demonstrated to potentially reduce life expectancy in growth hormone deficiency(GHD). The aim of this study was to evaluate cardiovascular abnormalities and atherosclerotic changes in adults with childhood-onset GHD in whom GH treatment had been stopped at the achievement of final height. METHODS:Nine patients with childhood-onset GHD(7 idiopathic and 2 organic), with an age of 24.0+/-.0 year, were studied. Clinical characteristics of subjects were determined and blood pressure, body mass index(BMI), and serum concentrations of lipids were measured. Structural and functional evaluation of cardiovascular system was performed by M-mode echocardiography and linear phase array imaging transducer. RESULTS:BMI of patients was 27.3+/-.7 mg/m2, and four patients(44%) were overweight(BMI 25-30 mg/m2), but none was obese(BMI >30 mg/m2). The percentage of patients who had total cholesterol > or = 200 mg/dL, triglyceride > or = 150 mg/dL, LDL cholesterol > or = 140 mg/dL, and HDL cholesterol < or = 40 mg/dL were 56%, 44%, 33 %, and 44%, respectively. Interventricular septum thickness(IVST), left ventricular posterior wall thickness(LVPWT), left ventricular end-diastolic internal diameter (LVID), left ventricular mass index(LVMI) of patients were 6.4+/-2.1 mm(SDS -1.5+/-1.1), 6.3+/-1.2 mm(SDS -2.1+/-0.8), 44.9+/-4.3 mm(SDS -1.0+/-0.9), and 85.4+/-94.8 g/m2 (SDS -0.5+/-6.8), respectively. The number of patients whose IVST, LVPWT, LVID, and LVMI were decreased(<-2SD) were 4(44%), 5(56%), 1(11%), and 6(67%), respectively. Carotid artery intima-media thickness(IMT) was 0.86+/-0.22 mm, and it was increased(>2SD) in 3 patients(33%). Three out of four patients with IVST lower than -2SD had increased carotid artery IMT, whereas none of five patients with IVST higher than -2SD had increased carotid artery IMT. There were no differences in echocardiographic findings between groups according to sex, age, duration of disease, duration after GH discontinuation, BMI, and severity of dyslipidemia. CONCLUSION: Decreases in IVST, LVPWT, and LVMI, and an increase in carotid artery IMT were observed in a significant number of patients with childhood-onset GHD. These findings support the need of GH replacement after completion of growth and careful evaluation of cardiovascular changes in patients with childhood-onset GHD.

PURPOSE:Improved adult final height(FH) is a major goal in the treatment of children with short stature due to growth hormone deficiency(GHD). The purpose of this study was to evaluate final height in idiopathic and organic GHD children after long-term growth hormone(GH) treatment. METHODS:Twenty five(16 males and 9 females) patients with GHD(14 idiopathic and 11 organic GHD) were included. GHD was diagnosed by two or more GH provocation tests(peak GH level <10 ng/mL). All subjects had multiple pituitary hormone deficiencies, and aged 10.7+/-.5(5.5-14) years at the start of GH treatment. The patients were treated with GH 0.45-0.7 IU/kg/week in 3-7 divided doses for 6.9+/-.8(5.2-10) years. Treatment was ended when growth velocity reached lower than 2 cm/year and/or bone age reached 16 years. Standard auxologic measurements were performed at the start of GH treatment and at every 6 month after initial GH treatment. RESULTS:FH was 166.9+/-.8 cm, which was not significantly lower than target height(167.1+/-.9 cm) and predicted adult height(169.1+/-5 cm). FH SDS was significantly improved to -0.8+/-.5 compared with -3.4+/-.0 of height SDS at the start of GH treatment. The largest height increment was observed in the first year of GH treatment, with a gradual decrease in the following years. There was no difference in FH and FH SDS between idiopathic and organic GHD. Unwanted serious adverse events were not observed in all patients during GH therapy. CONCLUSION: Early diagnosis and continuous treatment with optimal doses of GH to near adult height improve the outcome in children with short stature due to idiopathic and organic GHD.

An epidemiologic investigation was conducted to identify the source of infection and the mode of transmission of typhoid fever outbreak occurred in Ohchun middle and high schools located in Young il Gun, Kyungpook Province from May 21 to Jun 4, 1994. Four out of 13 hospitalized students in three general hospitals in Pohang City were culture positive typhoid fever (Salmonella typhi Group D). Review of the in and outpatient logbooks of the three general hospitals in Pohang City, county health center and local clinics in the vicinity of the Ohchun middle and high schools suggested that the outbreak was confined to the schools. Drinking water source of the schools was two underground water pumps that had no treatment facilities; one in northern end and the other in southern end of the main school building. However, the southern water pump was closed on April 28, 1994 because a recent test for the water revealed E-coli suggesting a possible fecal contamination. Two hundred twenty students stated that they had experienced symptoms related to typhoid fever since April l, 1994 in a self administered questionaire survey of all of the 2, 226 students. Personal interviews with these 220 students were performed to confirm the clinical history together with a rectal swab culture for typhoid fever and Widal test. A total of 39 patients were detected; 15 confirmed cases (culture-positive) and 24 suspected cases (symptom positive with equal to or greater than 1:160 titer of Salmonella O-antibody or 1:320 titer of H-antibody titer in Widal test). The epidemic curve showed a unimodal curve with a peak on the second week(17 May, 1994) and tailed down to the 5th week (22 28 May, 1994). The overall incidence rate of typhoid fever was 1.8 per 100 students; 1.5 (1.6 for male, 1.5 for female) in the middle school and 2. 4 (6. 2 for male, 0. 4 for female) in the high school. When contrasted with the students who did not drink water at all in the school, the relative risks of incidence rate of typhoid fever for the students who drank the underground water of the school, both underground water and water brought from home, or water brought from home only were 55.5, 19.0, and 3.0 respectively. Three classes which had especially high incidence rates of typhoid fever were located in the southern part of the main school building, where the contaminated underground water pump is located. These findings suggested that the source of infection was the contaminated underground water of the school. Both of the two underground water pumps were closed permanently and the public running water was supplied to the schools.

OBJECTIVES: The purpose of this study was to assess the clinical and polysomnographic characteristics of Korean patients with obstructive sleep apnea syndrome (OSAS), especially in relation to differences due to age and gender. METHODS: All subjects were consecutive patients who were proven to have OSAS with nocturnal polysomnography. They were interviewed with a structured interview format including sociodemographic information, past medical history, medication, and sleep-related history. Simultaneously, they were also given Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) to answer in order to check subjective sleep quality and subjective sleepiness. RESULTS: Mean age of the 308 subjects was 49.5+/-13.3 years, with 77.6% of the subjects being males and 22.4% of the subjects being females. The aging effects on the sleep architecture in Korean OSAS corresponded with normal aging, but with the effect of OSAS itself superimposed, the extent of aging effects was more marked than that of normal aging. The severity of Korean patients of OSAS was not correlated with age. When divided into age subgroups, significant correlation was found between RDI and BMI in patients of each subgroup of those in the 4th to 7th decades. The oldest subgroup (>70 years) described their subjective sleep quality as poorer than any other age subgroups, despite of less subjective drowsiness. The severity of OSAS and the change of sleep architecture of male subjects turned out to be severer than those of female ones. The female/male ratio of the subjects tended to increase with aging. CONCLUSIONS: The aging effect on the sleep architecture in Korean OSAS seems to be a mixture of the changes by normal aging and sleep disorder per se. The severity of OSAS was not correlated with age, but highly correlated with BMI. The severity of OSAS and the change of sleep architecture of male patients were severer than those of female ones.

Control of tuberculosis is threatened by widesread emergence of drug resistant Mycobacterium tuberculosis. Rifampin is a key component among therapeutic regimens for the tuberculosis; therefore patients in whom resistance to this drug develop have a poor outlook, particularly if rifampin resistance is associated with resistance to other tuberculosis drugs. The purpose of this study was to detect the mutation in rpoB gene of rifampin resistant M. tuberculosis in Korea and to evaluate the usefulness of the method in clinical aspects. A sample of 80 M. tuberculosis was studied, and it included 40 rifampin resistance isolates and 40 rifampin sensitive isolates by conventional methods. The detection method involved the amplification by polymerase chain reaction (PCR) of the Rif' region and the identification of mutations by single-strand DNA conformation polymorphism analysis (SSCP) of the amplification products (157 bp). Mutation were identified in 39 of 40 rifampin resistant isolates, and in 1 of 40 rifampin sensitive isolates.

Control of tuberculosis is threatened by widespread emergence of drug resistance in Mycobacterium tuberculosis. Understanding the molecular basis of resistance might lead to development of novel rapid methods for diagnosing drug resistance. Rifampin is a key component among therapeutic regimens for the tuberculosis; therefore, patients who have drug resistance do not convalesce satisfactorily. The molecular mechanism of resistance to rifampin in M. tuberulosis has been elucidated. Substitutions of a limited number of highly conserved amino acids encoded by the rpoB gene are responsible for the ""single-step"" high-level resistance of M. tuberculosis to rifampin. Currently, two genotype-based protocols allow drug test from minimally grown cultured materials: (i)mutation identification by direct sequencing of PCR-amplified material. and (ii)mutation screening by PCR-SSCP. The purpose of this study is to evaluate the usefulness of the both methods. A sample of 75 isolates of M. tuberculosis was studied, and it inculded 36 rifampin-resistant strains and 39 rifampin-sensitive strains by conventional methods. Mutaions were identified in 36 rifampin-resistant isolates but in none of 39 sensitive isolates. All mutations were clustered within a region of 23 amino acids. Both methods allow detection of rifampin resistance in 2 to 3 days and will thus help in the early management of infection by M. tuberculosis.
