The purpose of this study was to assess how job stiess affects the nursing performance of emergerncy room nurses. Data were collected from 210 emergency room nurses at 20 general hospitals, with more than 200 beds, in Pusan, Taegu and Kungbuk province, between October 5 and October 15, 1998. The instruments used for this study were the job stress scale which was developed by Mae Ja, Kim and Mi Ok, Gu(1984), and nursing performance of nurses scale developed by Kwi Ae, Chung(1989). Data Analysis was done using t-test, ANOVA, Tukey test, and Pearson Correlation. The results were as follows : 1. The highest rank of job stress items, emergency room nursing were as follows with lessening order when physicians delegate their clinical responsibilities to nurses(M=3.12+/-0.69). The most stressed factor among the nursing works was reported as night duty(M =2.99+/-0.87). 2. The mean score of nursing performance items, to prevent patient from falling or other injury(M = 3.69+/-0.50). 3. Our study reveals that there was statistically significant negative correlation relationship between stress level and emergency room nursing performance(r= -0.14, p=0.0454), in other words, the more stress the nurses experienced, the weaker their nursing performance became. Two factors, heavy work load(r=0.30, p=0.0001), and poor compensation(r =0.15, p =0.031). were negativly related to nursing performance. 4. The study revealed that the group with monthly income experienced less stress(F=2.71, p= 0.0461). Also, the degree of stress was significantly lower in the group with work experience (F=3.01, p=0.0313). Stress varied according to position superintendent nurse showed a lower level of stress than lay nurses and change nurses (F=2.93, p=0.0349). 5. There was significant difference in the degree of nursing perfnrm~nre according to religion (F= 3.97, p=0.0088). In conclusion, there was statistically significant negative correlations between job stress and nursing performance, so there is need for special consideration in nursing administration in terms of reducing the job stress in emergency nursing. Suggestions based on this study as follows. 1. Further study is necessary to examine variables that influence job stress and nursing performance. 2. The expem~ntaI study is needed for an effectiveness of systerrntic and in-lividual effort in order to reduce or manage nurses'stress in the emergency room.

Effect of Mercury chloride on the synthesis of NO2- and ATP were observed in EMT-6 cells which were culture with cytokines(IL-1alpha and IFN-gamma) and various concentrations of mercury chloride from 0.05 to 0.08 M. Viability of EMT-6 cells were observed above 90% in almost groups. There were not significant differences in the viability between mercury supplemented groups and control group. It suggests viability of EMT-6 cells were not influenced by these concentrations of mercury chloride. Results of the synthesis of nitrite showed significant time and group effect. There is a significant interaction effect between concentration of mercury chloride and culture time. The effect of various concentration of mercury chloride is not the same for all levels of culture time. There were significant differences in the synthesis of nitrite between mercury chloride supplemented groups and control group, and the synthesis of nitrite in EMT-6 cell by the supplement of mercury chloride was significantly decreased in a dose-dependent manner. Results of the synthesis of ATP showed a significant group effect, and the time main effect and the Group x Time interaction were also significant. There were significant differences in the synthesis of ATP between mercury chloride supplemented groups and control group, and the synthesis of ATP in EMT-6 cell by the supplement of mercury chloride was significantly decreased in a dose-dependent manner. These results suggest that the disorder of cell mediated immunity by mercury chloride could be related to the inhibition of nitric oxide synthesis which will be caused by the decreased synthesis of ATP.

A retrospective study was made of the previous medical records of 47 infants with congenital syphilis born from mothers with untreated syphilis at Severance Hospital, Yonsei University College of Medicine during the years 1972 through 1983 The VDRL titer of these infants was higher than 1: 8 with reactive FT.A-ABS test. They were subjectd to hematologic examinations and the results were as follow s, 1. Of 46 infants with congenital syphilis, anemia was observed in thirty-one (68%) Reticulocytosis occurred in seventeen(89%) of nineteen infants with congenital syphilis having the mean value of 6. 0%. 3, Of 4.7 infants with congenital syphilis, leucocytosis was noted in seveenteen 4, Thrombocytopenia was observed in twenty (64%) of thirty-one infants with congenital syphilis.

We compared 87 portographic filling defects detected by portal CT in 64 patients were compared with those obtained by indirect portography. The indirect portography could visualize portogram only in anterior-posterior view. But the portal portal CT could visualize both portogram and hepatogram. We examined the portal CT and indirect portography and compared the accuracy of the both methods to evaluate the limitation and significance of the indirect protography. The mass shape lesions were seen on the portal CT which means portal flow defects of the mass lesions only could not depict totally in indirect portography (0%, 0/41). And the larger defects than real mass lesion were seen in portal CT means mass with associated portal flow defect and find portal vein invasion around the mass in 52% (24/46) of the indirect portography. Among them, only 66% of mass were detected correctly in the indirect portography comparing with mass lesion in portal CT. In summary, indirect portogram could not detect small filling defects which detected in portal CT and could not depict the extent of large filling defects. It also could not visualize correctly the protal flow in non-lesion side of the liver parenchyma.

PURPOSE: To identify the four layers based on intranodular vascular nature visible in multiphase incremental bolus dynamic CT and to determine any differential points according to various factors of liver abscess with this vascular nature or not. MATERIALS AND METHODS: We categonized 29 cases of confirmed liver abscess into three different groups according to presence of four layers visible in early phase(arterial phase) of CT. Three groups were compared in regard to the results of antiamebic antibody test and bacteriologic study and presense of cholangitic abscess and internal septation. RESULTS: We could separate four layers, innermost hypodense central cavitary lesion, hyperdense granular tissue, hypodense abscess wall and outermost hyperdense compensatory hypervascular zone in 18 cases(62%), only two layers, cavity and wall in six cases(21%), and characteristically we could find three layers without innermost cavitary lesion in five cases(17%). But we couldn't find significant correlations between various clinical factors of liver abscess and our vascular groups. CONCLUSION: Our method of CT could represent four layers based on vascularity in 62% of cases. And also could find the unusual inflammatory mass containing three layer which must be differentiated from other malignant solid mass. But we couldn't find differential point between various clinical factor of liver abscess and imaging diagnosis. We think that with the improvement of hardware such as spiral CT, identification of four layers will be earier and will be very helpful in early detection and proper treatment planning of liver abscess.
