Necleolar organizer regions(NORs) ARE LOOPS OF DNA which transcribe to ribosomal RNA by RNA polymerase I. Since NOR-associated proteins are argyrophilic, silver staining method has been used for demonstration of AgNORs. The numbers and/or configurations of NORs may reflect the activities of cells in hyperplastic and neoplastic conditions. To evaluated the applicability of AgNORs in the diagnosis of hepatocellular carcinoma, the author had performed silver staining on the routinely processed, formalin-fixed, paraffin-embedded sections of 14 cases of normal liver(control), 23 cirrhotic liver, and 21 hepatocellular carcinoma. The results are summarized as follows: 1) The mean number of AgNORs per nucleus(mAgNOR) of normal liver, cirrhotic liver and hepatocellular carcinoma was 1.45+/-0.07, 2.53+/-0.38 and 5.52+/-1.63, respectively. The difference of mAgNOR between normal and cirrhotic liver, and between cirrhotic liver and hepatocellular carcinoma was statistically significant, respectively(p<0.01). 2) The percentage of nuclei showing five or more AgNORs per nucleus(pAgNOR) was 0.07% in normal liver, 7.59% in cirrhotic liver, and 60.49% in hepatocellular carcinoma. 3) AgNORs in hepatocellular carcinoma were large, pleomorphic and irregularly clumped, in addition to increase of mAgNOR and high pAgNOR. In conclusion, the increase of mAgNOR, high pAgNOR and large, irregular AgNORs are regarded as an additional helpful finding for the histopathological diagnosis of hepatocellular carcinoma.

Total 481 cases of gallstones from Korean patients operated at Keimyung University Dongsan Hospital during the last 6 years were classified by macroscopic view according to the classification of Sato, et al and reviewed with a special reference to age, sex, and kinds and sites of gallstones. Gallstrones were present predominatly in the age of 50-60 years, the average 52. Sex ratio (M:F) was nearly equal, being 1:1.05. Gallbladder was the most frequent site, comprising 53.2%, followed by common bile duct, 23.3% and intrahepatic location, 3.7%. Macroscopic classification revealed pigment gallstones in 53.0% (calcium bilirubinate, 41.8%; black, 11.2%); cholesterol gallstones in 36.2%, of which mixed stone being 33.1%. Cholesterol gallstones occurred predominantly in 50-60 years of age with a prediletion to females. On the contrary, elderly persons more than 60 years of age had calciu bilirubinate stones. No sex difference was found in the calcium bilirubinate stones. Eightly-six percent of cholesterol gallstones were present in the gallbladder only. Common bile duct stones were mostly composed of pigment gallstones in 80.4%.

Two unusual and rare forms of Brenner tumor are reported and the literatures are reviewed. The one, "proliferating" Brenner tumor, morphologically resembling low grade papillary transitional cell carcinoma of urinary bladder and regarded as a third variant intermediate between the benign and malignant forms; the other, malignant Brenner tumor of right ovary, corresponding to grade III transitional cell carcinoma of urinarybladder with areas of invasive squamous cell carcinoma and benign Brenner tumor of left ovary, combined with bilateral cystic teratomas. These tumors give additional support to the concept that Brenner tumors are composted of epithelium of urinary tract(urothelial) type.

Peutz-Jeghers polyp with pseudoinvasion is characterized by the presence of mucosal islands within muscle layer often associated with mucinous cysts. It occurs when mucosal components completely penetrate the muscularis propria, and shows no cytologic signs of malignancy. In most instances, the lesion may be the result of forces exerted during intussusception in the involved small intestine. We describe a case of Peutz-Jeghers polyposis with pseudoinvasion in a 24-year-old female patient. This patient presented with intussusception and a segmental resection of the ileum was performed. Microscopically, it disclosed a hamartomatous polyp with pseudoinvasion. There were glandular islands and mucinous cysts embedded within the bundle of muscle, layer, extending, to the subserosa. There was o evidence of cellular dysplasia or desmoplasia.

The concept of comfort has been regarded as a core concept of nursing and it has been frequently used as one of main goals of nursing care. Promoting comfort has been a very important objective in clinical nursing practice. There have been some ambiguities in defining the concept of 'comfort" among nursing scholars. Therefore it was necessary to analyse the concept of comfort for clearer definition to be able to share among scholars. This study is an attempt to analyse concept of comfort and to do it according to a series of concept development processes described by Walker and Avant. Based on the results of the study, the attributes of scope, precedence and consequence of comfort were identified : 1. Attributes 1) stability 2) directionality 3) equilibrium 4) firmness 2. Scope 1) physical 2) social 3) emotional 4) spiritua~ 3. Precedence and Consequence 1) precedence (1) instability (2) unsatisfied needs 2) consequence (1) physical & psychological relaxation (2) enhancement of self-worth (3) enhancement of self-efficacy (4) satisfied needs.

This study was performed on 50 cases of primary breast cancer removed surgically during the period 1990~1991 and compared the results of four morphologic methods developed for the detection of estrogen receptors, progesterone receptors, monoclonal antibody PCNA immunoreactivity, and the mean number of argyrophilic nucleolar organizer regions(mAgNORs) to ascertain the prognostic significance and also to detect highly malignant heterogenous cancer. To determine the validity of these measurements, a variance analysis was done with Kruskal-Wallis 1-way ANOVA. The results showed that the significant correlation between histologic grade and ER/PR status(P=0.005/P=0.015), the borderline significant correlation between mAgNORs and ER/PR status(P=0.08), and between AgNORs and stage(P=0.07), PCNA has no correlation with ER/PR status(P=0.25), clinical stage and histologic grade. In follow up, four cases of invasive ductal carcinoma with ER/PR, developed early and rapid metastasis within 2 years, three of them were classified as histologic grade 3 and another case was grade 2, whereas two of them were classified ans stage III(+) and the rest were in stage IIB(+) and stage IIA(-). The mAgNOR count of these four cases were ranged from 3.32 to 4.29 which were in the aneuploid category most likely. One of them had rather stormy rapid course with multiple organ metastases resulting death within one year. These results indicated that ductal carcinoma(>2cm size) with ER-/PR- and high mAgNOR level or high PCNA grade, and hihg histologic grade had h highly malignant course, marked by rapidly developing metastases. Thus we concluded that the status of ER/PR alone in tumor tissue is an important information for selecting hormone treatment btu, for the ultimate prognosis, is a weak indicator. Therefore for early detection of such heterogenous tumor, besides ER/PR, AgNORs or PCNA, histologic grade and tumor size are very useful as biological indicators of prognosis. The status ER/PR in combination with these indicators are more accurate and provide better basis on which to base a decision for early implementation of chemotherapy from which to give probably benefit by inhibition of rapid progress.

To evaluate the ultrastructural changes and the mechanism causing liver injury by lead, light and electron microscopic(LM and EM) examination using Timm sulphide silver method(TSM) was done. Sprague-Dawley rats were divided into a control and 3 experimental groups. The experimental groups were orally administered 0.5% lead acetate(LA). Group 1 received a one time dose of 10 ml of LA by gastric intubation. Groups 2 and 3 continuously received LA instead of drinking water. The control group was composed of 3 rats in each group which did not receive any treatment. Rats of group 1, 2 and 3 and control were sacrificed at 1/2, 1, 1 1/2 hours, 2 days, and at 1, 2, 4, 6 and 8 weeks later, except group 3. Before sacrifice, they were perfused with 0.1% sodium sulphide and 2.5% glutaraldehyde through the abdominal aorta for TSM. The liver was taken for LM and EM examinations. Blood lead concentration began to increase from the 2nd day up to 3.29 microgram/ml at 2nd week, and the urinary delta-ALA level showed a steady increase from the 2nd day. LM and EM examination of liver revealed that absorbed lead granules in group 1 were transported into sinusoidal spaces, Kupffer cells, and the hepatocytes within 1 hour and then disappeared 1/2 hour thereafter. In group 2 deposited lead was found in the hepatocytic cytosol bound to mitochondria. That in turn inhibited mitochondrial respiration with resultant mitochondrial swelling at the 1st week and thereafter at 6th week myelin figure formation and condensation of mitochondria, and peroxisomes were increased at 8th week. Based on these results it can be concluded that a transient intake of subletal dose of LA is biotransformed completely by periportal hepatocytes within 1 1/2 hours, but excessively accumulated lead can induce liver cell injury due to lipid peroxidation of membrane by direct toxic effect of lead and by products of lipid peroxidation. We postulate that lead acetate triggers presumably primarily mitochondrial membrane injury and then other organellar changes may play a role in disturbance of a network of interacting of key events capable of causing cell death.

Well-being has been considered to be an important nursing concept. However, there is no agreement among nurse researchers as to a conceptual definition of well-being and a similar concept to well -being. Clarification of the concept, well-being in nursing, is necessary to promote communication among nurses and to efficiently apply nursing intervention. This research was designed to analyze the concept and to make a definition of well-being in the lives of Korean Elderly. The study used the concept analysis approach developed by Walker and Avant(1995), and interviews. Firstly, well-being was defined as the balance and harmony of the internal and external environments and as the pursuit of improvement. Attributes of well-being were defined as follows: 1) homeostasis 2) harmony 3) fulfilment 4) pursuit of improvement And empirical referents were followed as: 1) health status, degree of activities of daily living, 2) degree of happiness, degree of satisfaction, 3) self-efficacy, self-esteem, 4) support, interpersonal relationships, social-leisure activity, 5) economic status, 6) degree of belief, 7) space and facilities Consequently, this study has identified the definition and attributes of "well -being" and has located empirical referents through concept analysis and interviews.

This investigation was aimed to study the effect of contrast media on the cardiovascular system. So in thisstudy, pithed rats were used whether alteration in cardiovascular system by contrast media were controlledcentrally. Furthermore, several hypertonic solutions were also used to clarify the effect of contrast media. Theresults are as follows: 1. Intravenous injection of contrast media in rats(2.5m/kg) caused hypotension andbradycardia. The effects were neither blocked by pretreatment of atropine nor pyribenzamine+atropine. 2. NaCl4.7%, dextrose 24.8%, urea 9.0% and glycerol 10.1%(v/v) which were equiosmolar with contrast media, causedhypotension, but did not affect the heart rate. 3. In pithed rats, intravenous injection of Angiografin increasedblood pressure in a dose-dependant manner, and caused decrease in heart rate compared with those of control rats. 4. In pithed rats, bradycardia by intravascular injection with Angiografin was partialy blocked by atropine. 5.Metrizamide of which iodine content was adjusted to 280 mg/ml caused increased in blood pressure when was injectedintravenously in pithed rats with little effect on heart rate. 6. When perfused with contrast media in rathindlimb at 15ml/kg speed both perfusion pressure and flow effluent incereased, simultaneously. These resultssuggest that hypotension might be caused by the central effect due to hyperosmolarity of contrast media andbrachycardia caused by both parasympathetic stimulation and direct inhibitory action on the cardiac conductivesystem.
