The purpose of this study is to investigate the effect of job stress and social support on the organizational effectiveness of hospital employees and to examine the role of social support in the experience of job stress among the employees. Previous studies have yielded mixed results regarding the role of social support. Some studies provide supporting evidence for the buffering effect of social support, while others do not. Still others report findings about reverse buffering effects. These inconsistent findings are, in part, accounted for by methodological problems such as poor measurement, small sample size, and the existence of high multicollinearity. To examine more rigorously the role of social support in relation to the negative effects of job stress, this study was carefully designed to overcome methodolgical shortcomings found in the past research. In addition, unlike the previous studies, which were concerned mostly with health-related variables as consequences of job stress, in this study, three work-related variables (job satisfaction, organizational commitment, and intent to stay) which had close relationships with organizational effectiveness were examined as output variables. The sample used in this study consisted of 353 employees from a university hospital in the suburbs of seoul. Data were collected with self-administered questionnaires and analyzed using canonical analysis and hierarchical regression analysis. The results of this study indicate that; (l) job stress has negative main effects on job satisfaction, organizational commitment, and intent to stay; (2) social support has positive main effects on the same three output variables, (3) social support does not moderate the harmful effects of job stress on the three outcome variables, and (4) the three-way interaction effects of (social support * job stress * gender) and of (social support * job stress * education) are not supported The implications of these findings for the management of human resources are discussed.

The glandular lesions of the uterine cervix can be classified into endocervical glandular dysplasia (EGD), adenocarcinoma in situ (AIS) and adenocarcinoma, but the diagnostic criteria and the continuity of endocervical glandular lesions are still controversial. The aim of this study was to evaluate the significance of immunohistochemical findings of p53 and MIB-1 in the discrimination and the continuity of EGD, AIS and adenocarcinoma. The materials for the study included 11 cases of adenocarcinoma, 7 cases of AIS, 12 cases of high grade EGD, and 19 cases of low grade EGD. Also included were eleven benign glandular lesions (5 cases of tuboendometrial metaplasia, 3 cases of mesonephric remnant, 3 cases of microglandular hyperplasia). A strong reaction of more than 5% of the glandular epithelial nuclei was interpreted as positive for p53 protein. MIB-1 expression was analyzed semiquantitatively as negative, 1 , 2 , 3 , depending on the percentage of positive nuclei (less than 1%, 1~9%, 10~39%, > or = 40%, respectively). p53 protein expression was found in 3 (27.3%) out of 11 cases of adenocarcinoma, and 2 (28.6%) out of 7 cases of AIS. But all of high and low grade EGD cases were negative. High MIB-1 labelling index (> or =10%) was found in all adenocarcinoma cases and in 3 (42.9%) out of 7 cases of AIS. But only 2 (17.7%) out of 12 cases of high grade EGD showed high MIB-1 labelling index, and all of low grade EGD and benign lesions showed negligible MIB-1 positivities. In summary, MIB-1 labelling index might be valuable in the discrimination of malignant glandular lesions and endocervical glandular dysplasia from benign lesions, but p53 expression could be a useful parameter in the discrimination of malignant glandular lesions from endocervical glandular dysplasia and benign lesions.

Objective: Cerebral white matter changes (WMCs) and silent brain infarcts (SBIs) are common radiological findings in neurologically asymptomatic elderly people. Their presence is associated with an increased risk of stroke or dementia. Homocysteine (Hcy) can cause atherosclerosis and may thus act as a useful marker of stroke prior to symptom onset. This study aimed to evaluate the utility of Hcy as a surrogate marker for early intervention for stroke in community-dwelling healthy elderly persons with cerebrovascular lesions such as WMCs and SBIs. Methods: We assessed the relationship between the Hcy level and presence of WMCs/SBIs on brain computed tomography (CT) in 554 elderly individuals aged ≥65 years with no history of stroke or dementia. Results: The mean age of the participants was 74.43±7.32 years. Of the 554 patients, 106 (19.1%) had WMCs and/or SBI findings on brain CT. The mean Hcy level was higher in participants with WMCs/SBIs (P=0.001). The WMCs/SBIs group had a significantly greater number of participants with high Hcy levels than the non-WMCs/SBIs group (P<0.001). High Hcy levels (≥12.3 μmol/L) was significantly associated with WMCs and SBIs even after adjusting for age, Korean Mini Mental Status Examination score, education level, and vascular risk factors such as hypertension, diabetes, hyperlipidemia and smoking status. Conclusion: The result of our study suggests that regular monitoring of homocysteine level as a modifiable risk factor may be helpful for predicting the association of cerebrovascular lesions such as WMCs and SBIs for the prevention of future ischemic stroke and cognitive impairment.

The effect of androgen in the development of the normal prostate and the evolution of benign prostatic hypertrophy (BPH), and prostatic adenocarcinoma has been proven. In addition to androgen, estrogen and progesterone are also thought to play a role in the pathogenesis of BPH and carcinoma. However, their exact roles are not yet known because there is no conclusive evidence. Thirty cases of prostatic adenocarcinoma and 16 cases of BPH were studied. Immunohistochemical staining for estrogen receptor (ER) and progesterone receptor (PR) in epithelial and stromal cells, respectively was performed and the results were assessed semiquantitatively based on the number of positive cells per 100 total cells. Slides were scored as negative; less than 5% of cells, 1 ; 6~15% of cells, 2 ; 16~25% of cells, and 3 ; more than 26% of cells. The relationship between ER and PR expression and the patient's age, histologic grade, and clinical stage was evaluated in prostatic adenocarcinomas. ER was negative in epithelial and in stromal cells for all prostatic adenocarcinomas and BPH cases. The PR expression in epithelial cells and in stromal cells of BPH was noted in 15 (93.8%) and 16 (100.0%) out of 16, respectively. The PR expression of carcinoma cells and stromal cells in prostatic adenocarcinoma was found in 28 (93.3%) and 23 out of 30 (76.7%), respectively. The PR immunoreactivities of stromal cells around carcinoma were 3 in 18 cases, 2 in one case, and 1 in 4 cases, but those of epithelial and stromal cells of BPH and carcinoma cells of prostatic carcinoma were similar to each other with a value of 3 in most cases. The PR expression rate of stromal cells around carcinoma was significantly correlated with the patient's age (p=0.044), but not with histologic grade and clinical stage. In summary, estrogen does not have a direct effect on the biological behavior of BPH and prostatic adenocarcinoma, but progesterone appears to play a role in the pathogenesis of BPH and prostatic adenocarcinoma. Further studies should clarify the biological role of progesterone in the human prostate.

A 59-year-old male farmer, an alcohol addict, has experienced repeated bullous skin lesions on the erythematous base over the exposed areas of tbe skin, especially on the face and hands, after sun-light exposure. The face showed hyperpigmenation, hypertrichosis and sclerodermoid changes. And also there were hypopigmented scars on the dorsum of the hands and cIaw-1ike fingers. Characteristic laboratory findings were as follows: Urine appeared portwine color and fluoresced under the Woods Iight. A 24-hour urine collection contamed 4l32ug of uroporphyrin and 3815ug of corproporphyrin. BSP retention(7% in 45 Min.) was increased, and A/G ratio(0. 8:1) was inverted. Gamma globulin(44, 9%) was markedly increased on serum electrophoresis. Roentgenograms revealed minimal tuberculosis on the chest P-A and superficial gastritis on the upper G-I series. Electrocardiogram showed left ventricular hypertrophy. Pathological findings of the specimen obtained from sclerodermoid lesion of the forehead revealed hypermelanosis in the basal cell layer and amorphous, basophilic collagen degeneration in the upper dermis, on the other hand loss of sinusoids due to swelling of hepatocytes and chomic inflammatory cell infiltrate in the interlobular septa were noticed on the specimen taken from the liver. For treatment, phlebotomy and metabolic alkalinization were trjed.
