Osteosarcoma is a malignant tumor arising from the undifferentiated fibrous tissue of bone and one of the mostcommon pirmary malignant tumors of bone. The diagnosis of osteosarcoma is based one can be diagnosed with areasonable degree of confidence from the conbination of the lesion site, age and radiological findings. This is aclinical and radiological observation of 40 cases of osteosarcoma which were experienced at Chonnam NationalUniversity Hospital, Chosum University Hospital and Kwangju Christian Hospital from 1978 to 1981. The results wereas follows; 1. The peak incidence was in the age group from 10 to 19 years in 21 cases (52.5%). 2. In sexdistribution, male group showed slightly higer incidence than in female group with the ratio of 1.35;1. 3. Themost commonly affected site was proximal tibia(35%). The lesion was found around the knee in 65% of the studiedcases. 4. Increment of the level of serum alkaline phosphase was observed in 25 cases (62.5%), and the averagevalue of serum alkaline phosphature in these cases was 5.6 Bessay Lowry units. 5. Radiographically, osteoblastictype was 14 cases (35%), and soft tissue mass shadow with calcification was observed in 34 cases (85%). 6.Cortical destruction was observed in 30 cases (75%), and soft tissue mass shadow with calcification was observedin 34 cases (85%). 7. Solid periosteal reaction, sunburst periosteal reaction and Codman's triangle were observedin 35%, 57.5% and 22.5% respectively. 8. At the first visit, lung meatastasis was found in 5 cases (12.5%) andinguinal lymphnode metastasis in 2 cases (5%)

This study was to compare changes in health behaviors, motivational factors, cardiovascular risk factors, and functional status (SIP) after implementing the 6-month motivation-enhancing program to institutionalized elderly women. METHODS: Sixty-four elderly women participated. Face to face interviews with blood sampling and anthropometric assessment were conducted at the pretest, 10 weeks and 6 months during the program. RESULTS: 1. The program participants showed significantly better health behaviors over 6 months. The mean motivational level was also significantly improved, especially for perceived benefits, perceived barriers, and emotional salience. 2. The mean of cardiovascular risk factors for the participants was 21.8 at the level of low to moderate risk. After completing the program, total risk score was significantly decreased to 18.7 at 10 weeks, and further to 17.7 at 6 months. A significant reduction was also found in HDL and LDL-cholesterol levels, blood pressure, obesity, inactivity, and stress. 3. The functional status (SIP) was 11% at the baseline and significantly changed in positive direction at 10 weeks (M=9.3) and at 6 month (M=6.3). The significant improvement was also found in physical and psychosocial dimensions and sleep/rest dimension. CONCLUSION: The motivation enhancing program was effective to reduce cardiovascular risks and to improve the functional status of institutionalized elderly women by motivating them to perform better health behaviors.

A 12 years old Korean girl was seen on 10 Oct. 1969 with chief complaint of a large fleshy mass extruded out of the orbit associated with ocular pain of mild degree for several months. Her parents were first noticed that the girl's right eye had a peculiar reflex from the pupillary zone in 2 years of her age. She was advised by a local clinician to correct surgicaIly someday later in her childhood. At the age of four, the pupillary margin of the affected eye had become distorted and they became aware of the eyeball was a little protruded and the grade of protrusion had slowly advanced as she had grown up. About a year ago the patient suffered from sudden attack of severe ocular pain associated with vomiting. Having experienced the recurrences of similar attack several times, she at last in Sept. 1969 met a spontaneous outburst of the extruded mass from which the purulent and bloody contents flowed out. It was to be regretted that the history could not reveal when and how the globe had been disorganized as completely as such that no trace of configuration of the anterior segment could be recognized. Familial and past history were not contributory except measle with good recovery at 2 years of age. On examination, the left eye had good vision and no structural changes, wherease the right side showed a marked extrurusion of fleshy mass out of the lid aperture. The mass had a relatively smooth and congested coverage of the conjunctiva except it had the fistulae through which a small amount of the purulent and bloody discharge flowed out under the digital pressure. It was felt somewhat elastic and movable with a broad base into the orbit. On its surface no trace of the cornea or the other global structures could be found. Physical examinations of the whole body including regional lymphnodes revealed normal X-ray Was of chest, skuIl and optic foramina were normal. On 14 Oct. 1969 under general anesthesia an orbital exentration was undertaken because of either probability of a malignant tumor or a long standing intraocular inflammation. In the way of procedure necrotic contents bursted out by mechanical pressure through the weak point, i.e. the fistulae, and correspondingly the tumorous mass became softened. Confirming no hard mass palpable into the orbit, the operating procedure shifted to do partial exentration. The extirpated mass was subjected to the histological study. Grossly, the dissected area revealed that it contained a well preserved structure of sclera on the one side and completly necrotised material on the other, but it did not contain any remnants of the ordinary global structures such as cornea, iris, lens, vitreous and choroid. The hollowed space partially surrounded by scleral structure was filled with the dark and gelatinous materia. The mass was as a whole rather soft Histological examination showed numerous gland like proliferations composed of poorly differentiated and unpigment columner cells having relatively large nuclei, some of which showed a mitotic figure. These were conceivable to be of an embryonic retina. The lumina of the gland like structures with the various sizes and shapes were filled with a pink staining coagulum and an extremly delicate and regularly arranged fibrillar structure. In some parts the tumor consisted of solid cellular conglomeration with rosett like arrangement and in the other necrotic masses containing tumor cells in all stages of degeneration. For the most part and the surrounding structure of the tumor cells, the picture showed likely to be a diffuse inflammation with an infiltration of polymorphonuclear cells, partly vessels being mostly of capillaries and recent hemorrhages, but the cartilage was not found.

PURPOSE: The purpose of this study was to examine the level of intention to quit smoking and to identify factors influencing intention to quit among patients with coronary heart disease. Method: The subjects consisted of 80 male patients with coronary heart disease (angina pectoris, myocardial infarction) at three hospitals in Seoul. The data were collected with self reporting in a structured questionnaire. Stepwise multiple regression was used to identify predictors of intention to quit. Included variables were attitudes toward smoking cessation, subjective norms, perceived behavioral control, usefulness of smoking cessation, and previous attempts to quit. RESULT: 1. The mean score for intention to quit was 11.1(+/-6.1) which was lower than median score of the scale. 2. There were significant correlations between the all predictive variables and the intention to quit(r=.24-.48, p<.05). 3. usefulness of smoking cessation, perceived behavioral control, and previous attempts to quit explained 34.6% of the variance for intention to quit. CONCLUSION: usefulness of smoking cessation, perceived behavioral control, and previous attempts to quit were identified as important variables in explaining the intention to quit smoking among patients with coronary heart disease. Thus, it is necessary to try to enhance this factors for increasing intention to quit among patients with coronary heart disease.

The purpose of this study was to analyse the current adult nursing curriculum content in diploma and baccaleurate level nursing schools. The Study was initiated by the Korean Academic Society of Adult Nursing and data were collected from these institutions from March 1997 to April 1998. The questionnaire was constructed after several meetings of researchers which included course description, objectives, conceptual framework, credits(theory and practicum), number of teaching staffs, content and hours for each content. The questionnaire was sent to all of the nursing schools(41 baccalaureate and 62 diploma) in the nation and the response rate were 53.7% in baccalaureate and 25.8% in diploma schools. Primary analysis was took place during summer workship of 1997 Korean Academic Society of Adult Nursing. The second analysis was carried out after additional data of detailed content and hours in adult nursing course were obtained from the schools. The result of primary analysis were as below : 1) The consensus in philosophy of adult nursing was drawn. The client of adult nursing was defined as individual over 18 years who has psychological, physical, social and spiritual aspects and interacting with environment. The client is a member of family and community. The students who finished the course should be able to adapt nursing process to their clients, and improve quality of life. The client, nursing process and nursing were common concepts which included in their conceptual framework. 2) Theory credits ranged 9-18(mean 14.1), practicum credits ranged 5-12(mean 8.1). The number of teaching staffs ranged from 2-6(mean 3.2). 3) The content which most hours assigned to were neuro/endocrine(mean 30.8 hours) gastrointestinal(mean 28.4 hours), cardiovascular(mean 28.6 hours) and respiratory(mean 22.7 hours) systems. 4) Areas taught by other profession(mostly physician) were eye, ear, nose, throat integumentary, radiation therapy, neuromuscular, rehabilitation, respiratory physiology, male genitourinary, pathology and anesthesiology. 5) Contents overlap with other course content should be rearranged in each school curriculums. Improvement of RN national board examination is prerequsite in order to improve adult nursing education in Korea. The result of second analysis were as below : 1) Credits required for graduation were 130-175 in baccalaureate, 93-134 in diploma. Thirteen to Twenty-eight percent of total credits required for nursing major were credits of adult nursing. 2) Mean hours of total adult nursing lecture were 217 in baccalareuate and 212 in diploma. 3) Disease process occupied more hours than nursing process in adult nursing theory. It is suggested to include all nursing educational institutions in order to complete the survey, to delineate the core contents of adult nursing and rate of hours between theory and practise by Korean Academic Society of Adult Nursing.

BACKGROUND: Caveolin-1 is a principal component of caveolae membranes in vivo. Although expression of caveolae structure and expression of caveolin family, caveolin-1, -2 and -3, was known in chondrocytes, the functional role of caveolae and caveolins in chondrocytes remains unknown. In this study, we investigated the role of caveolin-1 in articular chondrocytes. METHODS: Rabbit articular chondrocytes were prepared from cartilage slices of 2-week-old New Zealand white rabbits by enzymatic digestion. Caveolin-1 cDNA was transfected to articular chondrocytes using LipofectaminePLUS. The cyclooxygenase-2 (COX-2) expression levels were determined by immunoblot analysis, immunostaining, immunohistochemistry, and prostaglandin E2 (PGE2) assay was used to measure the COX-2 activity. RESULTS: Ectopic expression of caveolin-1 induced COX-2 expression and activity, as indicated by immunoblot analysis and PGE2 assay. And also, overexpression of caveolin-1 stimulated activation of p38 kinase and ERK-1/ -2. Inhibition of p38 kinase and ERK-1/-2 with SB203580 and PD98059, respectively, led to a dose-dependent decrease COX-2 expression and PGE2 production in caveolin-1-transfected cells. CONCLUSION: Taken together, our data suggest that ectopic expression of caveolin-1 contributes to the expression and activity of COX-2 in articular chondrocytes through MAP kinase pathway.

PURPOSE: To evaluate whether radial rigidity measured using RigiScan(R) represents the intracorporeal pressure effectively. MATERIALS AND METHODS: From January 1998 to May 1999, total of 23 patients with erectile dysfunction were evaluated by RigiScan(R) and duplex ultrasonography after the intracorporeal injection of prostaglandin E1. Peak systolic velocity and end diastolic velocity were measured by duplex ultrasonography and then the resistance index was calculated as (peak systolic velocity-end diastolic velocity)/(peak systolic velocity). Radial rigidity of penile tip and base was measured by RigiScanR . The results were analyzed statistically by PC-SPSS version 7.5. RESULTS: There were statistically significant correlations between radial rigidity of penile tip and base and the resistance index by Spearman's correlation analysis, respectively (r=0.680, p<0.001)(r=0.703, p<0.001). When radial rigidity of penile tip and base exceeded 60% of maximum, radial rigidity of penile tip and base again correlated well with the resistance index, respectively (r=0.659, p=0.020)(r=0.759, p=0.011). Based on clinically determined degree of erection, radial rigidity of penile tip and base represented the intracorporeal pressure effectively. CONCLUSIONS: Radial rigidity measured by RigiScan(R) represents the intracorporeal pressure effectively.

Withaferin A (WFA) is known as a constituent of Ayurvedic medicinal plant, Withania somnifera, and has been used for thousands of years. Although WFA has been used for the treatment of osteoarthritis (OA) and has a wide range of biochemical and pharmacologic activities, there are no findings suggesting its properties on chondrocytes or cartilage. The aim of the present study is to investigate the effects of WFA on apoptosis with focus on generation of intracellular reactive oxygen species (ROS). Here we showed that WFA significantly increased the generation of intracellular ROS in a dose-dependent manner. We also determined that WFA markedly leads to apoptosis as evidenced by accumulation of p53 by Western blot analysis. N-Acetyl-L-Cystein (NAC), an antioxidant, prevented WFA-caused expression of p53 and inhibited apoptosis of chondrocytes. We also found that WFA causes the activation of PI3K/Akt and JNKinase. Inhibition of PI3K/Akt and JNKinase with LY294002 (LY)/triciribine (TB) or SP600125 (SP) in WFA-treated cells reduced accumulation of p53 and inhibited fragmented DNA. Our findings suggested that apoptosis caused by WFA-induced intracellular ROS generation is regulated through PI3K/Akt and JNKinase in rabbit articular chondrocytes.
