This study was performed to investigate the effect of chamomile, sage, and green tea intakes on anti oxidative capacity in 15-month-old rats. Dried powders of three plants were analyzed to determine the amount of total flavonoids, $\beta$-carotene, vitamin C, vitamin E, and dietary fibers. In order to examine the change of antioxidative capacity in old rats, forty-eight Sprague-Dawley male rats weighing 621.2$\pm$9.5 g were divided into four groups according to body weight and fed for four weeks with each experimental diet of three dried powders and control diet. Plasma and liver thiobarbituric acid reactive substances (TBARS) levels and xanthine oxidase (XO) activities, erythrocyte and liver superoxide dismutase (SOD) activities and plasma vitamin A, C, E, and total carotenoids levels were measured. The total flavonoids and vitamin C contents were the highest in green tea powder. Beta-carotene and vitamin E contents were not significantly different among all three dried powders. Total dietary fiber contents also were not different among all three dried powders, but soluble dietary fiber contents of chamomile was higher than other two dried powders. Plasma TBARS level was found to be significantly lower in all the experimental groups as compared to control group. Chamomile powder group, especially, showed the lowest level among all experimental groups. Liver TBARS levels of experimental groups were also lower than that of control group and significant differences were observed in chamomile and green tea groups compared to control. Plasma XO activity of green tea group was significantly lower than control group. Liver XO activities of green tea and chamomile groups were significantly lower than control group. Erythrocyte SOD activity was not significantly different among all the groups. However, liver SOD activities of sage and green tea groups showed a significant increase as compared to control group. Plasma vitamin A level was not significantly different among all the groups. Plasma total carotenoids levels were found to be significantly higher in experimental groups as compared to control group. Plasma vitamin E level of chamomile group and vitamin C level of green tea group showed the highest level among all the groups. In conclusion, chamomile, sage, and green tea intakes had an effect on improving antioxidative capacity in 15-month-old rats. Effects of green tea and chamomile powders, especially, were higher than sage powder.

A trial with twenty-four newly weaned Awassi lambs (initial body weight=21.5$\pm$0.8 kg) was conducted using a 3$\times$2 factorial design to study the effect of feeding three sources of protein supplements (soybean meal (SBM), sunflower seed meal (SSM), and cottonseed meal (CSM)), either untreated or formaldehyde-treated on the growth performance and carcass traits of Awassi lambs. Lambs were randomly assigned to one of the six diets (4 lambs/treatment diet) and were individually fed for a period of 107 days. Experimental diets were isonitrogenous and isocaloric. Final live weight and average daily gain (ADG) were affected by both source of protein and formaldehyde treatment (undegradable protein). Lambs fed untreated diets had better (p<0.01) daily gain compared to those fed formaldehyde-treated diets. Similarly total feed intake per animal was significantly (p<0.05) affected by protein source and formaldehyde treatment. Formaldehyde treatment caused a significant decrease (p<0.01) in feed intake compared to lambs fed untreated diets. Feed requirement per unit of gain was not affected by formaldehyde treatment during all periods of the experiment except for the second period (the second 28 day period), whereby untreated SBM, SSM and CSM had better feed conversion ratio (FCR) than the treated groups. Source of protein had a moderate effect (p<0.10) on FCR but had a significant effect (p<0.05) on hot and cold carcass weight, digestive tract empty weight and liver weight, with lambs fed SBM having higher values than lambs fed SSM and CSM diets. Supplementation with undegradable protein had a significant effect (p<0.05) on dressing-out percentage (p<0.05), final live weight, and hot and cold carcass weight (p<0.01). The lower values pertain to lambs fed treated diets compared to lambs fed untreated diets. In general, there were no significant differences among all carcass linear dimensions, carcass cut weights and dissected loin tissue weights for both treatments (protein source and formaldehyde treatment). Supplementation with undegradable protein but not the source of protein resulted in significantly higher dissected leg total bone weight (p<0.05), tibia and femur weight (p<0.05), and femur length (p<0.01) at the same carcass weight. Results suggest that the treatment of SBM, SSM and CSM with formaldehyde did not improve efficiency of feed utilization, lamb performance or carcass traits and that the SBM diet resulted in an increase in lamb performance compared to other experimental diets.

Background: Reconstruction surgery of mitral valve regurgitation is now considered as an effective operative technique and has shown good long-term results. Although reconstructive surgery of mitral valve has been performed since 1970s, we have started only in early 1990s in full scale because of small number of the mitral regurgitation compared to mitral stenosis and lack of knowledge from the viewpoint of patients and physicians. Material and Method: From January 1992 to December 1996, 100 patients underwent repair of the mitral valve for mitral regurgitation with or without mitral stenosis in Seoul National University Hospital. 45(45%) of the patients were men and 55(55%) were women. The mean age was 39.9$\pm$14.4 years. The causes of the mitral regurgitation were rheumatic in 61, degenerative in 28 and others in 11. According to the Carpentier's pathological classification of mitral regurgitation 5 patients were type I. 55 patients were type II and 40 patients were type III. 7 patients underwent concomitant aortic valvuloplasty and 8 patients underwent aortic valve replacement. 7 patients underwent Maze operation or pulmonary vein isolation. Result: There were no operative death but 3 major operative complications: 2patients were postoperative low cardiac output syndrome(needed intra-aortic ballon pump support) and 1 patient was postoperative bleeding. There was one late death(1.0%) The cause of death was sepsis secondary to acute bacterial endocarditis. 3 patients required reoperation for recurred mitral regurgitation. There were no statistically significant risk factors for reoperation. The other 96 patients showed no or mild degree of mitral regurgitation 99 survivors were in NYHA functional class I or II. There were two throumboembolisms but no anticoagulation-related complications. Conclusion: We concluded that mitral valve repair could be performed successfully in most cases of mitral regurgitation even in the rheumatic and combined lesions with very low operative mortality and morbidity. The early results are very promising.

Objectives: The purpose of this study is to investigate human health risk assessment of indoor air pollutants at small-sized public-use facilities (e.g., daycare centers, hospital and elderly care facilities) that the susceptible population is mainly used. Methods: To assess indoor air quality (IAQ), the concentrations of indoor air contaminants such as HCHO, benzene, toluene, ethylbenzene, xylene, styrene, PM-10, CO, $NO_2$ and $O_3$ in air samples were measured according to the Indoor Air Quality Standard Method. By conducting the questionnaire survey, the major factors influencing IAQ were identified. Human health risk assessment was carried out in the consideration of type of use (user and worker) at 75 daycare centers, 34 hospitals and 40 elderly care facilities. Results: As a result of measurement of indoor air contaminants, the average concentration of HCHO and TVOCs in hospitals was higher than daycare centers and elderly care facilities, about 8.8 and 23.5% of hospitals were exceeded by IAQ standard. In human health risk assessment, for the user of daycare centers and elderly care facilities, the mean carcinogenic risk of HCHO inhalation was higher than acceptable value. Except for HCHO, other values were determined under acceptable risk. Similarly, for the worker of hospitals, the mean carcinogenic risk of HCHO inhalation was higher than acceptable value and other values were evaluated under acceptable risk. In contrast, the risk levels of other contaminants measured in elderly care facilities were acceptable. In the determination of factors influencing IAQ, the construction year, building type, ventilation time, and the use of air cleaner were identified. Conclusions: This study provides the information for establishing the plans of public health management of IAQ at small-sized public-use facilities that have not yet been placed under the regulation. The findings suggest the consideration of human health risk assessment results for the IAQ standards.

Background: In uncontrolled hemoptysis patient, bronchial arteriography and bronchial artery embolization (BAE) is a important procedure in diagnosis and treatment. The aim of this study is to assess the incidence of contrast-induced nephropathy and the risk factors of contrast-induced nephropathy (CIN) after bronchial arteriography and BAE. Methods: We retrospectively reviewed the medical records of the patients who underwent bronchial arteriography and BAE in two university hospitals from January 2003 to December 2011. CIN was defined as rise of serum creatinine more than 25% of baseline value or 0.5 mg/dL at between 48 hours and 96 hours after bronchial arteriography and BAE. We excluded patients who already had severe renal insufficiency (serum creatinine${\geq}4.0$) or had been receiving dialysis. Results: Of the total 100 screened patients, 88 patients met the enrollment criteria. CIN developed in 7 patients (8.0%). The mean duration between the exposure and development of CIN was $2.35{\pm}0.81$ days. By using multivariate analysis, serum albumin level was found to be significantly associated with the development of CIN (p=0.0219). Conclusion: These findings suggest that the incidence of CIN was higher than expected and patients with hypoalbuminemia should be monitored more carefully to prevent the development of CIN after bronchial arteriography and BAE.

This study was carried out to examine the physicochemical and microbiological characteristics of Korean and other countries chicken circulated in Tokyo, Japan. The breast meats of Korean, Japanese, and Chinese chickens and thigh meats of Korean, Japanese, Chinese, American, and Thai chicken were used. In the proximate analysis of breast meat, Korean chicken had the lowest crude protein and crude ash(P<0.01), but showed the highest content of moisture(P<0.001). TBA values of Japanese breast meat were higher than Korean and Chinese one. In thigh meat, crude fat of American one was significantly higher than the others(P<0.001), and had very high bacterial counts. Korean chicken thigh meats showed the lowest VBN values.

Heat penetration characteristics of retort pouched curry were studied to determine optimal sterilization conditions. Heating curve of retort pouched curry showed a simple logarithmic curve. The $f_h$ value (min.) of solid part in retort pouched curry was 1 min. higher than that of liquid part. $f_h$ value (min.) and $j_h$ value (heating lag factor) ranged from 8.3 min. to 12 min. and 1.0 to 1.17 respectively with increasing the ratio of solid to liquid and viscosity. $f_h$ value (min.) and $j_h$ value were significantly increased from 7.4 min. to 12.6 min. and 1.0 to 1.14 respectively with increasing thickness of the pouch from 11 to 15 mm. The low and medium volatile aroma components of retort pouched curry decreased during sterilization, which increased the high volatile aroma components. The retort pouched curry processed at $120^{\circ}C$, for 24 min. with $F_o$, value of $8{\sim}9$ could keep up a desirable quality without any remarkable deterioration.

Background: Breast cancer is the most common type of cancer in Jordan. Current efforts are focused on annual campaigns aimed at increasing awareness about breast cancer and encouraging women to conduct mammogram screening. In the absence of regular systematic screening for breast cancer in Jordan, there is a need to evaluate current mammography screening uptake and its predictors, assess women's knowledge and attitudes towards breast cancer and screening mammograms and to identify barriers to this preventive service. Materials and Methods: This cross-sectional study was conducted in six governorates in Jordan through face-to-face interviews on a random sample of women aged 40 to 69 years. Results: A total of 507 participants with mean age of $46.8{\pm}7.8$ years were interviewed. There was low participation rate in early detection of breast cancer practices. Breast self-examination, doctor examination and periodic mammography screening were reported by 34.9%, 16.8% and 8.6% of study participants, respectively. Additionally 3.8% underwent breast cancer screening at least once but not periodically, while 87.6% had never undergone mammography screening. Reported reasons for conducting the screening were: perceived benefit (50%); family history of breast cancer (23.1%); perceived severity (21.2%); and advice from friend or family member (5.8%). City residents have shown higher probability of undergoing mammogram than those who live in towns or villages. Results revealed negative perceptions and limited knowledge of study participants on breast cancer and breast cancer screening. The most commonly reported barriers for women who never underwent screening were: fear of results (63.8%); no support from surrounding environment (59.7); cost of the test (53.4%); and religious belief, i.e. Qadaa Wa Qadar (51.1%). Conclusions: In the absence of regular systematic screening for breast cancer in Jordan, the uptake of this preventive service is very low. It is essential for the country of Jordan to work on applying regular systematic mammography screening for breast cancer. Additionally, there is a need for improvement in the current health promotion programmes targeting breast cancer screening. Other areas that could be targeted in future initiatives in this field include access to screening in rural areas and removal of current barriers.

Background: No studies on male attitudes towards HPV and HPV vaccination have been conducted in Japan, and little is known globally whether attitudes of single fathers differ to those living with a female partner. This exploratory study assessed whether Japanese fathers were likely to have their daughter vaccinated against HPV in a publically funded program and whether any differences existed regarding attitudes and knowledge about HPV according to marital status. Materials and Methods: Subjects were 27 fathers (16 single; 11 married) who took part in a study on HPV vaccine acceptability aimed at primary caregivers of girls aged 11-14 yrs in three Japanese cities between July and December 2010. Results: Knowledge about HPV was extremely poor (mean score out of 13 being $2.74{\pm}3.22$) with only one (3.7%) participant believing he had been infected with HPV and most (81.4%) believing they had no or low future risk. No difference existed regarding knowledge or awareness of HPV according to marital status. Concerning perceived risk for daughters, single fathers were significantly more likely to believe their daughter was at risk for both HPV (87.5% versus 36.4%; p=0.01) and cervical cancer (75.0% versus 27.3%; p=0.02). Acceptability of free HPV vaccination was high at 92% with no difference according to marital status, however single fathers were significantly more likely (p=0.01) to pay when vaccination came at a cost. Concerns specific to single fathers included explaining the sexual nature of HPV and taking a daughter to a gynecologist to be vaccinated. Conclusions: Knowledge about HPV among Japanese fathers is poor, but HPV vaccine acceptability is high and does not differ by marital status. Providing sexual health education in schools that addresses lack of knowledge about HPV as well as information preferences expressed by single fathers, may not only increase HPV vaccine acceptance, but also actively involve men in cervical cancer prevention strategies. However, further large-scale quantitative studies are needed.

Actual evapotranspiration was measured over rice paddy field by Bowen ratio heat balance method and based on this, investigated was the reliability of actual evapotranpiration estimation from Class-A Pan and small pan evaporation and reference evapotranspiration calculated by modified Penman-Monteith model. Crop coefficients based on Class-A Pan and small pan evaporation and reference evapotranspiration by modified Penman-Monteith model were averaged to be 1.57. 1.10 and 1.49 over the whole rice growing season, respectively. Their respective coefficients of variation were 28.7. 22.7 and 12.8 percent, respectively. Crop coefficient based on modified Penman-Monteith model varied in good agreement with the trend of leaf area development, being greatest around heading stage.
