We investigated dietary effects of green tea powder (GTP) on plasma lipids, platelet aggregation, hemolysis, plasma TBARS, and liver enzymes. Thirty one volunteer diving women living on Jeju island consumed 4 g green tea powder daily for a period of four weeks and data for the study subjects were analyzed on the basis of diagnostic criteria for blood pressure (BP)(> or = 140/90 mmHg), plasma total cholesterol (TC)(> or = 200 mg/dL), and triglyceride (TG)(> or = 150mg/dL). Subjects with high BP had significantly higher TC and TG than those with normal BP. Subjects with higher TC had higher TG, and those with higher TG had lower HDL cholesterol. Platelet aggregation in the initial slope was significantly higher in subjects with normal BP, normal TC, or normal TG than their counterparts in high BP, TC, and TG. HDL cholesterol after GTP intake increased only in subject groups with normal BP, normal TC, or normal TG, and plasma TG after GTP intake decreased only in groups with higher BP, higher TG, or higher TC. Plasma TC and TG in subjects with normal BP increased after GTP intake. GTP intake caused a decrease in the initial slope of platelet aggregation in all subject groups with little effect on maximum aggregation. Total bilirubin showed a significant increase and GOT increased in all subject groups after GTP intake. Beneficial effects of short term intake of green tea powder might differ depending on the subject conditions in terms of blood pressure, plasma lipids, and other cardiovascular conditions. However, with the hypolipidemic, antithrombotic, and antioxidant actions of its bioactive flavonoids, long term usage of GTP or brewed green tea may provide preventive effects against cardiovascular disease.

Present study was conducted to investigate the effects of exercise and cholesterol diet on plasma and liver lipids, platelet aggregation, erythrocyte Na efflux and liver index such as GOT and GPT using Sprague Dawley rats. Forty rats were divided into four groups and fed control or 0.5% cholesterol diet with and without treadmill for six weeks. The final body weight of group fed cholesterol diet with exercise was somewhat decreased compared with group fed cholesterol diet without exercise. L.W/B.W ratio was significantly increased in groups fed cholesterol diet (p < 0.01), but exercise tended to decrease this ratio. Plasma total cholesterol was significantly increased and HDL-cholesterol was decreased in groups fed cholesterol diet (p < 0.01). Plasma triglyceride was significantly decreased in groups fed cholesterol diet compared with groups fed control diet (p < 0.01). Plasma triglyceride of groups with exercise was significantly decreased compared with their non exercising counterparts regardless diet (p < 0.05). Liver total cholesterol and triglyceride was significantly increased in groups fed cholesterol diet (p < 0.01), but exercise did not affect on these levels. Na-K ATPase was somewhat decreased in groups fed cholesterol diet, and exercise tended to recover the reduced Na-K ATPase. Na passive transport was significantly decreased in group fed control diet without exercise and significantly increased in group fed cholesterol diet with exercise, there were significant differences between groups (p < 0.05). There were no differences in total Na efflux and intracellular Na among groups, and total Na efflux was not correlated with intracellular Na. Hematocrit was significantly lower (p < 0.05) in group fed cholesterol diet without exercise compared with other groups. Platelet aggregation in the initial slope and the maximum was increased in groups fed cholesterol diet, but not statistically significant. Exercise especially increased the initial slope of aggregation. Plasma GOT and GPT was significantly increased in groups fed cholesterol diet (p < 0.01), and exercise in group fed cholesterol diet significantly decreased both GOT and GPT compared with the non exercising counterpart (p < 0.01). This study showed that cholesterol diet increases plasma and liver lipids and GOT and GPT, and exercise improves plasma and liver lipid profile and liver index of GOT and GPT preventing fatty liver.

OBJECTIVES: To determine changes in the incidence and pattern of eclampsia in Il Sin Christian Hospital over a 46-year period. METHODS: Information was collected from medical records of the 1910 eclamptic patients among 233,613 deliveries in Il Sin Christian Hospital from Jan. 1 1953 to Dec. 31 1998. Incidence, presentation, and management of eclampsia were reviewed retrospectively, and maternal mortality rate and perinatal mortality rate were calculated. Statistical analysis was done by Chi-squared and Fisher's exact test through two by two tables looking at relative changes between each study period. RESULTS: The overall incidence of eclampsia was 81.8 per 10,000 deliveries. The incidence of eclampsia had increased from 137.3/10,000 in 1953-1962 to 278.4/10,000 in 1963-1972, but the rate had reduced to 6.5/10,000 in 1993-1998. There was a statistically significant fall in the rate of eclampsia every decade between 1973 and 1992, but there has been steady decrease in the last study period. Convulsion occurred antepartum in 54% of patients, intrapartum in 29% and postpartum in 17%. With the reduction in the proportion of antepartum eclampsia, there has been a relative increase in that of intrapartum and postpartum eclampsia. Maternal death occurred in 59 cases among eclampsia, and maternal mortality rate was 3.1%. Maternal mortality rate had significantly decresed from 11.1% in 1953-1962 to 3.8% in 1963-1972, and there has been no maternal death from eclampsia since 1986. Postpartum eclampsia had increased death risk compared with antepartum or intrapartum eclampsia. There were 280 cases of perinatal death and overall perinatal mortality rate was 144.1 per 1000 deliveries. There was a significant decrease in the rate from 243.2/1000 in 1953-1962 to 141.5/1000 in 1963-1972, but the rate has risen steadily since 1983. CONCLUSIONS: With the improvement in antenatal care and management of eclampsia, the incidence of eclampsia and its associated maternal mortality has decreased over the last 46 years. But eclampsia still remains a significant complication of pregnancy with high maternal and perinatal mortality.

OBJECTIVES: Changes in plasma homovanillic acid(HVA) were investigated in neuroleptic responsive and non-responsive schizophrenics in order to delineate parameters of dopamine regulation, which may underlie differences in neuroleptic responsivity. METHOD: Twenty newly admitted acute schizophrenic patients were treated with haloperidol for 6 weeks. HVA was sampled at baseline, 3 days after initial neuroleptic dose, and after 1, 2, 3, 4, 6 weeks of treatment. Nine patients were classified as responders in this prospective haloperidol treatment trial. They had a score of change in the BPRS total scores of 25% or greater. Eleven patients were classified as nonresponders, based on a score of changes in the BPRS total scores of less than 25%. RESULTS: 1) The age of onset in respnder was older than nonresponder. 2) There were no significant changes in plasma HVA levels in total patients during 6 weeks haloperidol treatment period, but the nonreponders had a robust decrease in HVA level from baseline to 3 days and one week after haloperidol treatment in successive comparison. 3) There were no significant correlations between plasma HVA level and total scores of BPRS. CONCLUSIONS:This study suggested that neuroleptic non-responsive schizophrenics had a different plasma HVA concentration during haloperidol treatment but could not provide support to the idea that change in plasma HVA in response to neuroleptics can predict eventual clinical response to treatment. Further study is required in order to better characterize the changes in dopamine turnover in subgroups of schizophrenics.

PURPOSE: As health care needs for Lesbian, Gay, Bisexual and Transgender (LGBT) are becoming increasingly important, it has become imperative for the nurses to be attentive towards their health problems and provide nursing care with an open-minded attitude. Due to limited opportunity to provide direct nursing care to LGBT patients, it is hypothesized that simulation would provide good opportunity for students to experience LGBT nursing care in a safe environment. This study was conducted to develop and apply simulation of LGBT nursing care to ultimately provide unbiased nursing care for LGBT population and prepare basic data for LGBT nursing education.METHODS: This study was a single-group pre-post experimental design study for 57 senior nursing students based on the comparison of existing LGBT knowledge, general attitude towards LGBT, and nursing attitude towards LGBT before and after simulation. The scenario content included discussion of coming out issue, providing sexual health information, and supportive nursing care for LGBT population. Data were analyzed with descriptive statistics and Wilcoxon signed rank.RESULTS: Simulation education-led to a significant increase in LGBT knowledge and nursing attitude. However, there was no change in the general attitude towards LGBT.CONCLUSION: The results of this study suggest that LGBT education using simulation may be effective for nursing students and nurses from the point of concern for LGBT population. It is hypothesized that future LGBT educational programs might need more detailed information from both care recipients and nurses. Finally, LGBT education needs to be included in the nursing education curriculum.

We investigated dietary effects of prickly pear cactus (Opuntina ficus-indica) on plasma lipids, platelet aggregation (PA), hemolysis, plasma TBARS and liver enzymes. Twenty eight volunteer diving women in Jeju island had daily 20 g cactus tea containing 27% prickly pear cactus (PPC) powder for 4 weeks, and data for the study subjects were analyzed, on the basis of diagnostic criteria for blood pressure (BP)(> or = 140/90 mmHg), plasma cholesterol (> or = 200 mg/dL) and triglyceride (> or = 150 mg/dL). The subjects with higher BP had higher plasma total cholesterol (TC) and triglyceride (TG) concentrations than those with normal BP. Those with higher TC also had higher TG. Subjects with normal BP or normal TC had higher initial slope of PA than their higher counterpart in BP and TC. PPC intake decreased plasma TG in those with higher BP. PPC intake significantly decreased the elevated initial slope in groups with normal BP, TC, and TG. Hemolysis after PPC intake decreased significantly in all the subjects and plasma TBARS decreased in the subjects with higher plasma TC and higher TG. Glutamic-oxaloacetic transaminase (GOT) significantly increased and total bilirubin significantly decreased in all the subjects after PPC intake. The present study with diving women showed that beneficial effects of short term intake of prickly pear cactus might differ depending on the subject conditions in term of blood pressure, and plasma lipids. However, long term usage of prickly pear cactus may provide preventive effects of cardiovascular diseases to all the population, presumably by hypolipidemic, antithrombotic, and antioxidant actions of its bioactive flavonoids and soluble fiber.

PURPOSE: This study was to suggest the direction to the exercise intervention development for the stroke survivors. METHOD: 12 domestic and 54 foreign research papers about the exercise intervention for the stroke patients published during 1998~2007 were analyzed. RESULT: Among the papers, quasi-experimental design(75.8%) and multidisciplinary approach(60.6%) were the most frequent ones. The mean age of the respondents was 63.3 and the intervention was supplied for 7.14 weeks. The frequency of exercise was 3.87 per week and the exercise time was 1.88 hours. And physical research variables - such as ambulation, muscle strength, activities of daily living and balance - were more than psychosocial variables. This study suggested that the exercise intervention for the stroke survivors need to include aerobic exercise, muscle strengthening exercise, flexible exercise, body coordination, balance exercise. In addition we confirmed that the exercise intervention was revealed as an effective physiological parameters; such as maximum oxygen uptake quantity, blood pressure. CONCLUSION: We suggest that the further researchs are needed which include the intensity of exercise into the quantity of the exercise. Also researchers need to extend the motion intervention time for an effective sociopsychological variable and to try the meta analysis for the effective exercise intervention for the stroke survivors.

PURPOSE: The Sentinel lymph node (SLN) is the first draining node from the primary lesions, and is the first site of lymph node metastasis in malignancies. The aim of this study was to determine the feasibility of a SLN biopsy in patients with gastric cancer to assess the regional lymph node status. METHODS: A SLN biopsy was performed in 46 consecutive gastric cancer patients, with preoperative imaging stages of T1/T2, N0 and M0. Three hours prior to each operation, a (99m)Tc tin-colloid (2.0 ml, 1.0 mCi) was endoscopically injected into the gastric submucosa around the primary tumor. Subsequently, serial lymphoscintigraphy was performed using a dual head gamma camera. After the SLN biopsy had been performed using a gamma probe, the patients underwent a radical gastrectomy (D2 or D2+ alpha). The SLNs were cut and immediately frozen-sectioned. A paraffin block was then produced for permanent hematoxylin-eosin staining and immunohistochemistry (IHC). RESULTS: SLNs were successfully identified in 43 of the 46 patients (success rate, 93.5%), at an average of 2 (range, 1~8) per patient. The positive and negative predictive values, sensitivity and specificity of the SLN biopsy were 100 (11/11), 93.8 (30/32), 84.6% (11/13) and 100% (30/30), respectively. SLNs were located at the level I, I+II and II lymph nodes in 38 (88.4%), 2 (4.7%) and 3 (7.0%), respectively. No micrometastases of the SLNs was found on the IHC for cytokeratin. CONCLUSION: A sentinel lymph node (SLN) biopsy, using a radioisotope, in patients with gastric cancer is a technically feasible and accurate technique, and is a minimally invasive approach for assessing the nodal status in patients.
