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.

OBJECTIVE: To compare pregnancy and delivery complications in first births between women 35 years or older and those who are younger. METHODS: Matemal and newborn records for first births at Chonnam university hospital from January 1, 1988 to December 31, 1996 were studied. The study group included 123 women who were 35 years or older. A control group consisting of 120 younger women was used for comparison. The X2 test was used to identify trends in individual variables and outcomes. RESULTS: Premature rupture of membrane, uterine myoma, and malpresentation were much mare prevalent in the older nullipara. However, there were no significant differences in incidences of preeclampsia, placenta previa, and pyelonephritis between the older nullipara and younger nullipara groups. Older nullipara had a significantly higher incidence of Cesarean delivery than younger women, Elective cesarean section was performed only in the older nullipara and it was the most common indication for Cesarean delivery in older nullipara. Fetal distress and breech presentation as indications for Cesarean delivery were significantly more common in the older study group. There were no noticeable differences in postpartal complication between the groups. Pretam birth and low birth weight were much more common in the older nullipara. but there were no significant differences in small for gestational age, low Apgar score, perinatal morbidity and deaths between the groups. CONCLUSION: From the results, it was difficult to conclude that women 35 or older are pmne to higher risk pregnancies, compared to their younger counterparts. Although more incidences of premature rupture of membrane, preterm delivery, and Cesarean delivery were observed, there were no significant differences in other pregnancy and delivery complications. With appropriate obstetric care, it is most probable that first time pregnancies in older women will result in similar outcome as those in younger women.

PURPOSE: Tumor invasion and metastasis are multistep phenomina, involving proteolytic degradation of extracellular matrix (ECM) and alteration of cell adhesion. It is another oncologic therapeutic strategy to block tumor invasion and metastasis through analyzing the molecules which are involved in these processes. We examined the expressions of some of matrix metalloproteinases (MMPs) in colorectal cancer and analyze the correlation with clinical factors and survival. METHODS: Fifty-five patients with colorectal cancer who underwent surgical resection were included. The expressions of the MMP-2, -7, -9, and -12 in tumor tissue and normal mucosa using RT-PCR technique was carried out. We evaluated and analyzed the correlation among these molecules, clinical characteristics, and survival. RESULTS: Expressions of MMP-7, -9, and -12 were significantly higher in tumor tissue than in normal mucosa (P=0.00). The expressions of MMP-2 between cancer and normal mucosa had no significant difference but it had a significant difference according to the lymph node (LN) invasion (P=0.03) in tumor tissues. Three-year overall survival was worse in patient with high expression of MMP-2 compared to low expression. CONCLUSION: The expressions of MMP-7, -9, -12 in tumor tissue were higher than in normal mucosa and MMP-2 expression of tumor tissues had a significant difference according to LN invasion. MMP-2 overexpression seems to be a prognostic factor for 3-yr overall survival. But, large scale study with long term survival analysis will be needed for the prognostic significance of MMPs.

Tumor DNA content measured by flow cytometry may be a predictor in the prognosis of epithelial ovarian cancer, but the results have been inconsistent. It is recognized that these conflicting results are at least partly due to the variation of DNA content between the samples from the same patient(i.e., intratumoral DNA heterogeneity). The purposes of this retrospective study were to investigate the frequency and the nature of DNA heterogeneity in epithelial ovarian cancer and to evaluate the prognostic significance of DNA heterogenetiy itself. Thirty-two patients with stage II to IV epithelial ovarian cancer who were managed at Asan Medical Center between May 1993 and April 1996 were analysed. Measurements of the nuclear DNA content were performed on samples from primary and metastatic lesion using paraffin embedded archival tissues by Epics(Coulter Inc.) flow cytometry. In two cases, the metastatic tumor was minute and did not reveal a separable peak on repeated examination. DNA heterogeneity was defined as different ploidy pattern or difference of the DNA indices than 0.15 between primary and metastatic tumors. DNA heterogeneity was found in 11 cases(36.7%), and the number of cases with homogeneous diploid and that with homogeneous aneuploid tumor were 5(16.7%) and 14(46.7%) respectively. In evaluation of prognostic significance of DNA heterogeneity using correlation with serum CA 125 level after second course of chemotherapy and residual tumor size after cytoreductive surgery among these three groups, the patients with DNA heterogeneity were considered to show intermediate prognosis between those with homogeneous diploid and homogeneous aneuploid tumor. In conclusion, DNA heterogeneity in epithelial ovarian cancer is considerable in frequency and may have prognostic value.

PURPOSE: To describe the significance, incidence and characteristics of sonographic findings and long term outcomes of parafrontal horn cysts detected by screening cranial sonography done within the first week following birth. MATERIALS AND METHODS: 2122 first cranial ultrasound scans performed over a five year period were retrospectively evaluated and 23 neonates with parafrontal horn cysts were found (which are different from secondary cystic lesions). 17 cases had a birth weight of < 2400 gm with gestation between 30 and 35 weeks, 6 cases had a birth weight of > 2400 gm with gestation between 34 and 41 weeks. The size, shape and location of the parafrontal horn cysts and other associated abnormalities shown on the cranial sonogram were evaluated and sequential ultrasound study, maternal records, neonatal events and neurodevelopmental evaluations were retrospectively assessed. RESULTS: Of the 23 subjects, 21 had isolated parafrontal horn cysts and 2 had subependymal hemorrhages. There was no record of any abnormal perinatal history. The cysts were bilateral in 20 neonates and unilateral in the others. The size of the cysts ranged from 3 to 18 mm in diameter (mean 9 mm). Sonographic features of the parafrontal horn cysts were distinctive morphology (elliptical, thin walled) and location (adjacent to the tip of the frontal horn). In 17 of the cases a follow-up cranial sonography was performed, and all parafrontal horn cysts disappeared within 3 to 6 months. Neurodevelopmental outcomes were normal in those 17 cases. CONCLUSION: Screening cranial sonography of neonates discovers isolated parafrontal horn cyst. The incidence of parafrontal horn cysts in neonates in our study was 1.1%. They are present in the first week following birth and resolve themselves without medical treatment within a few months. In addition, they show normal neurodevelopment. The parafrontal cysts are suspected to be a benign variant of normal neurodevelopment.

PURPOSE: Diallyl disulfide (DADS) is a major organosulfur compound derived from garlic. It has been reported that DADS is able to inhibit the proliferation of several tumor cells. In this study, the effect of DADS was investigated in terms of the proliferation of AGS, gastric adenocarcinoma cell line at various concentrations. METHODS: The viability of cultured cells was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide assay. To detect the induction of apoptosis, Annexin V-FITC/propodium iodide (PI) staining assay was performed. Analysis of reactive oxygen species (ROS) and the distribution of cells in the cell cycle were measured by a flow cytometer. And using the Western blot analysis, the change of Fas, caspase-3, Bax, Bcl-2 activity was measured. RESULTS: The percentage of live AGS cells was decreased to 23% of that in the control group after 400 microM DADS treatment for 48 hours. The Annexin V positive/PI negative (apoptosis portion) area increased from low concentration of DADS to high concentration. When comparing among the DADS treatment groups, the amount of ROS production increased in a dose dependent manner. The percentage of sub-diploid DNA content increased from 8.71% at 50 microM to 25.74% at 400 microM DADS treatment group. The expressions of Fas, caspase-3, Bax were increased and that of Bcl-2 was decreased in a dose dependent manner. CONCLUSION: DADS decreases the viability of AGS cell lines and induces apoptosis in a dose-dependent manner. But the relationship of the anti-proliferative effect of DADS and related molecular changes were not clearly proportional to the concentration of DADS.

PURPOSE: The purpose of study was to identify how patients experienced chemotherapy-induced peripheral neuropathy (CIPN) and quality of life related to CIPN. METHODS: This was a descriptive research. We collected data from 105 patients with chemotherapy-induced peripheral neuropathy. They completed a self-reported questionnaire including Eastern Cooperative Oncology Group (EORTC) CIPN20 and items related to their disease and peripheral neuropathy. The investigators filled in part of items about disease and treatment. RESULTS: In the study, duration of peripheral neuropathy was 9.4 month and 54.3% of patients used pharmacological or non-pharmacological interventions. Patients reported the highest score for sensory scale and it's score was 38.74+/-20.24. The scores for motor scale and autonomic scale were 21.95+/-19.19 and 26.61+/-21.0 respectively. This showed that patients more suffered from sensory neuropathy than any other domain of neuropathy. The most frequently selected two items were 'did you have tingling fingers or hands?' and 'did you have tingling toes or feet?'. CONCLUSION: The results of this study will provide useful information for chemotherapy-induced peripheral neuropathy.

PURPOSE: The purposes of this study were to identify job definition, duties and tasks of Korean oncology Advanced Practice Nurses (APNs) and assess frequency, importance, and difficulty for each of duty and task using the DACUM method. METHODS: The DACUM committee was organized with nine oncology APNs. The committee documented the job definition, duties and tasks based on their daily job descriptions. Validity of the elicited duties and tasks was tested by a study team and 6 oncology APNs. Data were collected using a questionnaire survey from 53 oncology APNs. RESULTS: The job description of oncology APNs was identified 12 duties and 66 tasks. Among the twelve duties, 'education for patients/ families' was the most frequently performed and was the most important duty. 'Case management' was the most difficult duty. Among 66 tasks, 'providing education for patients/families' was most frequently performed. 'Providing education for patients/families' and 'assessing patient condition comprehensively' were the most important tasks. 'Implementation research' as the principal investigator was perceived as the most difficult task. CONCLUSION: In this study, Korean oncology APNs' job performances were identified and analyzed. It is recommended that job description for oncology APNs needs to be standardized and reshaped in advanced way in future.
