The female has previously been shown to be an independent risk factor for mortality and morbidity after coronary artery bypass grafting surgery (CABG). The aim of this retrospective study is to evaluate gender differences of the perioperative outcomes in elderly patients underwent CABG. Data for seventy elderly patients (>70 years) that underwent CABG (between January 2005 and July 2011) were divided into two groups: male patients (n=33, male group) and female patients group (n=37, female group). Heights, body weights, body surface area and coronary artery obstruction rate (right coronary artery territory) in the female group were lower than those of the male group ($P$ <0.05). History of hypertension, hyperlipidemia, congestive heart failure and percutaneous coronary artery intervention in the female group was higher than that of the male group ($P$ <0.05). Total cholesterol and brain natriuretic peptide levels in the female group were higher than those of the male group ($P$ <0.05). Platelet count in the female group was higher than the male group at preoperative (Pre-OP) period ($P$ <0.05). Erythrocyte count, hematocrit and hemoglobin levels in the female group were lower than those of the male group at Pre-OP period ($P$ <0.05). But, erythrocyte count, hematocrit and hemoglobin levels in the female group were higher than those of the Male group at postoperative (Post-OP) period ($P$ <0.05). Left ventricular ejection fraction in the female group was higher than the male group at Post-OP period ($P$ <0.05). Hospital stay length in the female group was higher than the male group ($P$ <0.05). Post-OP bleeding volume and incidence of ventricular premature contraction in the female group were lower than those of the male group ($P$ <0.05). These results suggest that despite female gender have a greater risk factors and require a longer hospitalization than male, there was no significant difference incidence of mortality and complication.

The purpose of this study is to assess dietary habits of the hazardous drinkers and the heavy episodic drinkers in Korean adults. The respondents consisted of 814 adults (415 male and 399 female) who are 20~69 years of age by random selection in partial area of Gyeonggi. A self-report questionnaire was used to cover questions regarding dietary habits, drinking behavior and physical activity. Total dietary habit scores in hazardous drinker group (63.25) was significantly lower than normal drinker group (68.61) in male respondents (P<0.001). Male hazardous drinker group less eat fruit (P<0.01), eat more processed food (P<0.01) than male normal drinker group. Female hazardous drinker group doesn't eat 3 meals a day than female normal drinker group. Total dietary habit scores in heavy episodic drinker group [occasional heavy episodic drinker (62.76), frequent heavy episodic drinker (63.77)] were significantly lower than abstainer group (69.16) in male respondents (P<0.001). Male heavy episodic drinker group less eat fruit (P<0.01), eats more processed food (P<0.01), salty food (P<0.001), sugary food (P<0.05), animal fat (P<0.01) and eats out often (P<0.01) than male abstainer group. Male heavy episodic drinker group significantly less apply nutrition knowledge to their life (P<0.05) and less exercise everyday-more than 1 hour (P<0.01) than male abstainer group. In drinking behavior index, AUDIT (alcohol use disorder identification test) score was negatively correlated with age (P<0.01). There was a positive correlation between dietary habits and physical activity (P<0.01) but there was negative correlation between dietary habits and AUDIT score (P<0.01). This study highlights that AUDIT score was negatively influenced dietary habits.

The purpose of this study was to compare nutrient intakes and blood lipids according to the obesity index of middle aged men. Subjects were assigned to one of the following groups based on percentage of body fat (%Fat),; normal weight (10-20% fat), overweight (20-25% fat) and obesity (over 25% fat). Nutrient intakes were evaluated based on questionnaires and 24 hour recall method and blood lipids were analyzed by blood analyzer. The results were as follows: 1) Nutrient intakes were that carbohydrate intake rate in obesity group was lower than normal group and lipids intake rate in obesity group was higher than normal group. The intake of riboflavin and folic acid were differ normal and obesity group (p < 0.05), and normal group ingested under recommended intake. 2) Total-cholesterol, LDL-cholesterol and blood pressure in obesity group were higher than normal group but the differences were not significant. The attack rate of coronary heart disease and blood glucose in obesity group is higher than normal group (p < 0.05). 3) The correlation of anthropometric measurements, blood lipid, blood glucose and blood pressure had significant results. Soft lean mass was associated BMI (p < 0.01), TC (p < 0.05), HDL (p < 0.05), LDL (p < 0.05) and SBP (p < 0.05). TG was associated TC (p < 0.05), HDL (p < 0.01), VLDL (p < 0.001) and Risk (p < 0.01). TC was associated LDL (p < 0.01) and Risk (p < 0.01). Blood glucose was associated TC (p < 0.05), LDL (p < 0.05), SBP (p < 0.05) and DBP (p < 0.05). These results suggest that reduction of body weight for the attack risk of obesity group in coronary heart disease.

The Purposes of this study were to examine plasma homovanillic acid(pHVA) levels and 5-hydroxyindoleacetic acid(pHIAA) levels in schizophrenics during haloperidol treatment, and to assess the association of pHVA and pHIM levels with their psychopathology and treatment responses. Fourteen patients entered the study and pHVA, pHIAA levels were measured at baseline, first week, second week and fourth week during treatment. Also, plasma haloperidol levels were measured at first week, second week and fourth week. Psychopathology was evaluated with Brief Psychiatric Rating Scale(BPRS) at baseline, 1st week, 2nd week and 4th week. 1) There were significant differences on the duration of illness and total BPRS scores at baseline between higher pHVA group(baseline pHVA level >7.72ng/mL) and lower pHVA group(baseline pHVA level <7.72ng/mL). 2) There was no significant difference on the duration of illness between higher pHIM group(baseline pHIAA level >3.18ng/mL). and lower pHIAA group(baseline pHIAA level <3.18ng/mL). 3) The Means of pHVA levels at 1 st week and 2nd week after treatment decreased significantly in the higher pHVA group and did not change in the lower pHVA group. 4) In the higher pHIAA group, the mean of pHIAA levels at 4th week after treatment decreased significantly, but did not change in the lower pHIAA group. 5) Between the higher pHIVA group and lower pHVA group, the response rates(percentile improvement) after treatment were not different from each other, but there was significant difference on the response rate between the lower pHIAA group and higher pHIM group at 2nd week. 6) There was significant correlation between total BPRS scores and pHVA levels in the higher pHVA group during treatment. The results suggest that repeated measurement of pHVA levels and pHIAA levels following antipsychotic treatment have prognostic significance for response. Also, shcizophrenics whose have relatively nigh levels of pHVA, or relatively low levels of pHIAA before treatment will show a favorable early responses to antipsychotics.

This study evaluated the Comparison of the Effectiveness of Pelvic Floor Muscle exercise and Biofeedback treatment for Genuine Stress Incontinence I assigned 60 participants to 2 groups : 30 to the pelvic floor muscle exercise group and 30 to the biofeedback group. Treatment protocol lasted for 6 weeks. Peak pressure, and duration time of pelvic muscle contraction were evaluated by a perineometer. Lower urinary symptoms, sexual matter and life style scores were achieved by using Jackson's scale. The treatment efficacy of the pelvic floor muscle exercise is compared with the biofeedback group and the main results of the comparison are as follows : 1. Pelvic muscle contraction 1) The peak pressure in the biofeedback group was significantly increased(P＝0.000). 2. The frequency and quantity of incontinence 1) The frequency of incontinence in the biofeedback group was significantly decreased(P＝0.000). 2) The quantity of incontinence in the biofeedback group was significantly decreased(P＝0.000). 3. The lower urinary symptoms Daily frequency(P＝0.000), nocturia(P＝0.000), urgency(P＝0.000), bladder pain(P＝0.000), unexplained incontinence(P＝0.048), wearing protection(P＝0.022), changing outer clothing(P＝0.005), hesitancy(P＝0.008), intermittent stream(P＝0.000), abnormal strength of stream(P＝0.004), retention(P＝0.000), incomplete emptying(P＝0.000), and inability to stop mid stream(P＝0.006) of the lower urinary symptoms in the biofeedbatk group were significantly decreased. 4. The sexual matters The dry vagina (P＝0.004) and pain during sexual Intercourse (P＝0.002) in the biofeedback group was significantly decreased. 5. The life style The fluid intake restriction(P＝0.007), affected daily task(P＝0.003), avoidance of places & situation(P＝0.003), interference in Physical activity (P＝0.002), interference in relationship with other people(P＝0.01), and feeling about the rest of life with urinary symptom(P＝0.000) in the biofeedback group were significantly decreased. In conclusion, the biofeedback treatment was more effective than the pelvic floor muscle exercise in genuine stress incontinence.

The purpose of this study is to investigate the utility of the pleural fluid cholesterol level in separating the exudates from the transudates, and in differentiating tuberculous exudates from non-tuberculous exudates, 52 patients with pleural effusion were involved in this prospective study. By predefined criteria, 40 of these effusions were classified as exudates (Group I) and 12 as transudates (Group II). Group I was subdivided into tuberculous exudates (Group A) and non-tuberculous exudates (Group B). The followings are parameters used in separating the exudates from the transudates; pleural protein (P-PROT) 3.0 g/dl, pleural protein/serum protein ratio (P/S PORT) 0.5, pleural LDH (P-LDH) 200 IU, pleural LDH/serum LDH ratio (P/S LDH) 0.6, pleural cholesterol (P-CHOL) 50 mg/dl and pleural cholesterol/serum cholesterol ratio (P/S CHOL) 0.4. Mean values of the parameters in each group were compared, and then misclassified rate and the dignostic efficiency for each parameter were calculated. The results were as follows; 1) Mean P-CHOL ($94.98{\pm}73.86\;mg/dl$) in Group I was higher than that ($36.5{\pm}26.5\;mg/dl$) in Group II (p<0.05), but there was no significant difference in mean P-CHOL between Group A and Group B. 2) Mean P/S CHOL ($0.64{\pm}0.39$) in Group I was also higher than that ($0.27{\pm}0.15$) in Group II (p<0.01), but no difference was observed in mean P/S CHOL between Group A and Group B. 3) Misclassified rates for each parameter in separating the exudates from the transudates were as follows; P-PROT 1.9%. P/S PROT 3.8%. P-CHOL 9.6%, P/S CHOL 11.5%, P/S LDH 11.5%, and P-LDH 17.3%. 4) Diagnostic efficiencies for each parameter in separating the exudates from the transudates were as follows; P-PROT 98.1%, P/S PROT 96.2%. P-CHOL 90.4%. P/S CHOL 88.5%, P/S LDH 88.5%, and P-LDH 82.7%. In conclusion, we think that the pleural fluid chloesterol level could be used as a supportive parameter in separating the exudates from the transudates, but could not be used as a parameter in differentiating tuberculous exudates from non-tuberculous exudates.

This study was performed to observe the role of Pneumocystis carinii as an etiologic agent of interstitial pneumonia in immunocompromised hosts. Total 90 male Sprague-Dawley rats, approxi. mately 150-180 g, were used. Fifteen of them were used as control group and remaining 75 (5 groups) were as immunosuppression groups; group 1 received prednisolone (25 mg/kg twice weekly) only; group 2 Prednisolone and tetracycline (75 mk/kg/day) ; group 3 Prednisolone, tetracycline and trimethoprim-sulfamethoxasole (50~250 mg/kg/day) : group 4 prednisolone and trimethoprim-sulfamethoxasole; and group 5 prednisolone and griseofulvin (300 mg/kg/day) until death. The survival days of each group rat were calculated, and upon death their lungs were removed immediately and then stamp smears were prepared and stained by Giemsa or toluidine blue O. For histopathologic observation, lungs were fixed in 10% formalin, cut into sections and stained with Gomori's methenamine silvei, hematoxylin-rosin, and Brovkn & Brenn stain. The results obtained were as follows: 1. The mean survival time of each group rat was 19.3$\pm$5.2 days (group 1), 41.1$\pm$14.0 days (group 2), 50.5$\pm$18.4 days (group 3), 43.0$\pm$22.9 days (group 4) or 21.8$\pm$5.1 days (group 5). Significant differences were noted between group 1 and group 2(p<0.01), group 1 and group 3 (p<0.01), and group 1 and group 4 (p<0.01), which represented bacterial infections were most fatal in immunocompromised rats. Group 5 revealed no difference in the survival day from group 1, while significant differences were noted between group 2 and group 5(P<0.01), group 3 and group 5(p<0.01), and group 4 and group 5(p<0, 01), which represented little importance of fungal infection as the cause of death of the rats. 2. The first fatality due to p. carinii pneumonia occurred 17 days after the beginning of the immunosuppression. The occurrence rate of P. carinii pneumonia in the decreasing order was 92.9% (group 3), 80.0% (group 2 and group 5), 78.6% (group 4) and 33.3% (group 1). With regard to the pathological stage of P. carinii pneumonia, the stage 1 was 11.3%, the stage 2, 28.3%, and the stage 3, 60.4%. 3. Viewing from the duration of immunosuppression, bacterial pneumonia chieay appeared in 1 month, mixed infections (P. carinii and bacteria, or p. carinii and fungi) in 1~2 months, and pure P. carinii pneumonia after 2 months. The present study revealed that P. carinii pneumonia was the most important cause of death of immunocompromised rats later than 1 month after the start of immunosuppression.
