From Jan. 1983 to June 1984 in Yonsei University Medical College 17 patients received curative resectivesurgery due to bronchogenic carcinoma. The following results were obtained by comparing the CT findings to theoperative and histological findings of those patients. 1. The histological types of 17 cases of bronchogeniccarcinoma were squamous cell Ca. 8 cases, adenocarcinoma 7 cases, and undifferentiated Ca. 2 cases. The both ofthe undifferentiated type were confirmed by post operative histological study. 2. The lesions showing falsepositivity of mediastinal invasion are enlarged but have well circumscribed margins and separated lymph nodes. 3.In contrast, the prediction of hilar infiltration by CT gave only 25% sensitivity, 77.8% specificity and 52.9%accuracy. 4. For the clinical staging done by CT, only 47.1% were in accordance with the surgical staging. 5.However, CT is useful in selecting the patients who need invasive staging before abandoning curative resection andin suggesting the type of invasive staging according to the location of the lesion.

We investigated the occurrence of color vision loss in 70 organic solvent mixtures exposed workers and in 47 controls. Color Vision was assessed with a color arrangement test designed to identify the defective color sense, the Han Double 15-Hue Test. The results of the test were no significant difference between exposed workers and controls in the proportion of subjects who committed one or two errors. Quantitative analysis, using color confusion index(CCI), showed no signifiant difference between exposed workers and controls. A significant linear correlation was present between age and CCI in both exposed workers(CCi=0.0056age + 0.94; r=0.23; p<0.05) and controls(CCI=0.0066age + 0.86; r=0.33; p<0.05). Qualitative analysis of the patterns on the hue circle showed that the prevalence of acquired dyschromatopsia was 21% in both and no significant difference. Multiple regression analyses showed that age was significantly related to color vision loss. These results did not provide evidence of a relationship between organic solvents exposure and incidence of color vision loss. In field studies for monitor the people at risk of the acquired color vision loss involving low-dose organic solvents exposed workers, both quantitative and qualitative information should be considered.

Hereditary angioedema is a rare genetic disease transmitted with a autosomal dominant trait result of a quantitative or functional defect of Cl inhibitor. We report three cases of heriditary angioedema from the same famly respectively the 35-year-old sister, the younger bn)ther of 32, and the younger sister of 20 The older sister died due to her airway being obstructel by acute laryngeal edema, and her you igirbrother and sister experienced recurrent episodes oswelling on the hand and forearm. The ore we examined the two patients serum complement levils to confirm diagnosis. In both, the r;ults showed decreased levels of Cl inhibitor and C4 which are the evidence of hereditary a giedema. The younger sister has been administered danazol (600mg/day) to prevent angioedem or 8 weeks, and we have not yet found a recurrenc of he symptoms. However, well cont ol the dosage of danazol because amenorchea has developec.

Nucleolar organizer regions are DNA loops encoding rihbosomal RNA production and detectable by the argyrophilia of their associated proteins(AgNORs). AgNOR numbers correlate with cellular proliferating activity. Many studies have shown a significnt difference in AgNOR counts between benign and malignant tumors. AgNOR counts were also helpful in differential diagnosis. For the evaluation of its diagnostic utility in gastric lesions, a silver staining technique was carried out in paraffin sections of 5 control cases, 5 benign peptic ulcers, 7 hyperplastic polyps, 10 tubular adenomas, 16 early gastric adenocarcinomas and 15 advanced gastric adenocarcinomas. The results were as follows. The mean numbers of AgNORs in early and advanced gastric adenocarcinomas(1.94 and 2.16) were significantly higher than those of normal foveolar epithelium(1.43) and epithelia of benign gastric ulcers(1.54), hyperplastic polyps(1.64) and tubular adenomas(1.79). In malignancy, there was increased variability in size and shape of AgNORs. There was little differences in mean AgNOR numbers between early and advanced gastric adenocarcinomas. Differentiation of the tumor made no difference in AgNOR numbers. From the above results, the AgNORs count, if its morphologic change are taken into consideration, is helpful in differentiation between malignant and non-malignant lesions.

The purpose of this study was to construct model of sexual adjustment in people with spinal cord injury and to determine factors that relate to sexual adjustment using methodological triangulation. A total of 134 persons who were registered members of spinal cord injury organization and admitted rehabilitation unit in the hospital were included in the study. Participants answered questionnaire concerning importance of life events, sexual concern, sexual adjustment. Qualitative data were collected through semi-structured indepth interviews from 10 individuals with spinal cord injury who were previously included in the quantitative study. Constant compatative method was used to analyze the data. The results were as follows: 1) With respect to eleven other areas of life, sex life ranked the sixth and economic status ranked the highest in terms of importance. However social life ranked the lowest among the 11areas. 2) Among seven topics related to sexuality were methods and techniques to achieve sexual satisfaction, and helping a partner cope emotionally with limitation on sexual dysfunction was the second greastest. 3) The mean score for sexual adjustment was 19.47 which can be considered. 4) A process on how individuals with spinal cord injury adjust to their changed sexual life immerged from the qualitative data. It includs 4 stages: 'stage of loss' 'stage of endeavoring' 'stage of effort' and 'stage of adjustment'. Categories showing context for the action/interaction strategies were 'steadiness' and 'rediscovery as a sexual being'. There were three factors which may stimulate the adjustment process while the others may interrupt it. Those factors included personal matters, family matters and social matters. The individuals may follow each stage step by step but may go back to the previous step depending on the outcomes of their adjustment. 5) There were three factors which may stimulate the adjustment process while the others may interrupt it. Those factors included personal matters, family matters and social matters.

Polymorphic reticulosis(PMR) is a unique clinicopathological entity of unknown etiology, which commonly present as an aggressive, necrotizing lesion of the upper respiratory tract. It is a separate nosologic entity from Wegener's granulomatosis and idiopathic mildine destructive disease. The origin of the cells composing polymorphic reticulosis has been controversial. We reviewed 15 cases of polymorphic reticulosis with respect to clinical and histologic bases, and immunohistochemical studies were done using UCHLI (CD45RO), as a T cell marker, CD-20 as a B cell marker and alpha- I -antichymotrypsin as a histiocytic marker. Almost all cases showed characteristic histologic and immunohistochemical features similar to those of peripheral T cell lymphoma. Thus, this study indidcated that polymorphic reticulosis is a type of malignant lymphoma of T cell lineage.

PURPOSE: The purpose of this study is to describe the findings of the transligamnetous type of the herniated lumbar disc (HLD) with magnetic resonance MR imaging. MATERIALS AND METHODS: We retrospectively analyzed the MR images of surgically proven 20 cases of transligamentous type of HLD from January 1, 1992 to August 20, 1992. The MR imaging was performed with 1. 0T MR unit, using sagittal spin echo (SE) and axial gradient echo (GE) techniques. RESULTS: The results were as follows;1) the interruption of black line of the posterior longitudinal ligament (PLL) was identified in 19 levels and 17 levels in sagittal SE and axial GE images, retrospectively;2) the widening of adjacent epidural fat space was demonstrated in 16 cases of central or posterolateral HLD. The herniated disc material, as compared with the parent intervertebral disc, showed intermediate signal intensity (SI) in 19 and low SI in 1 level on T1WI, high SI in 10, intermediate SI in 7, low SI in levels on T2WI, and high SI in 10, intermediate SI in 9, low SI in 1 level on GE images. CONCLUSION: The most important sign of the transligamentous type HLD on MRI was the interruption of the black line with additional finding of the widening of adjacent epidural fat space. The MR signal intensity of the herniated disc was variable. Axial GE image was valuable for the evaluation of the direction of HLD and it relationship with neural structure, but had no addiational information for the degree and biochemical change of HLD over SE image.

The purpose of this study is to identify and describe a process of sexual adjustment of individuals with spinal cord injury: and to describe and explore positive and negative influences on the adjustment process. This qualitative study was conducted with 10 Korean individuals with spinal cord injury who had been physically disabled for more than one year. Data were collected and analysed at a same time using grounded theory method. Major categories of this study showed a process how the individuals with spinal cord injury adjust to their individual life as sexual beings. The process included Changes of life caused by physical disability> Emotional distress> Stability of life> Recognition of self as a sexual being> Re-establishing own sense of values for sexual life> Behavioral efforts for restoration of sexual life> and individual responses to the behavioral efforts including Frustration> Resignation> Satisfaction> Dissatisfaction> and Limited satisfaction>. Initially physical aspects of sexuality seemed to be affected by spinal cord injuries. The changed physical aspects then influenced other aspects of their sexual life. Life satisfaction of each individual as a sexual being revealed as very subjective. It could be defined according to how the individual approved their sexual life no matter what and how much behavioral effort the person had done. In this study 3 types of sexual adjustment aspects were explored: 'Active adjustment' 'Passive adjustment' 'Maladjustment'. There were negative and positive factors influencing the adjustment process of individuals with spinal cord injury. Those factors might come from themselves. from families. or from social situations. Findings of this study suggested that sexual life of individuals with spinal cord injury should not be understood as a physical or behavioral matter. It was a combination of physical. psychological and social aspects of life. Therefore. appropriate rehabilitation programs for the sexual adjustment of individuals with spinal cord injury need to concern heterogeneous life values of them and obtain individualized services for each individual at a different stage of the sexual adjustment process.
