The purpose of this study was to determine the effect of bST treatment on embryo recovery and pregnancy rate following embryo transfer. Donor cows were superovulated with Folltropin-V and PGF$_2$$\alpha$ combination method and then inseminated with frozen semen 3 times 12 hrs interval. Donor and recipient cows were assigned to control and bST group, of which was given a single injection of bST (500 mg, im) at insemination or estrus detection. Embryo collection of superovulated cows were flushed nonsurgical method at 7 to 8 days after artificial insemination. The percentare and Mean$\pm$S.E. of transferable embryo was not significantly different between control and bST treatment (72.8%/5.9$\pm$4.5 vs. 83.7%15.1 $\pm$ 1.6). The percentage and Mean$\pm$S.E. of transferable embryo in non-summer season was significantly higher than in summer (81.8%/5.4$\pm$2.1 vs. 68.7%14.774.6; P<0.05). The pregnancy rate after embryo transfer in bST treatment was significantly higher than in control (64.0 vs. 47.1%; P<0.05). There was no significant difference in pregnancy rate between summer and non-summer (51.6 vs. 61.5%; P>0.05). The results indicated that InST treatment in recipient cows could improve the efficiency of transferable embryo production and pregnancy rate after embryo transfer, and non-summer season may be better far superovulation treatment and embryo transfer.

Purpose: Since there are few studies involving acute pancreatitis in children, we reviewed our experience with this medical condition to describe the clinical features. Methods: A retrospective analysis was conducted by reviewing the medical records of 41 patients with AP who were admitted to the Department of Pediatrics of Pusan National University Hospital between January 1996 and June 2007. Results: Twenty males and 21 females (mean age, 8.7${\pm}$4.5 years) were included. In 22 patients (53.7%), no definitive causes were found. The most common etiologies were choledochal cysts (22.0%). Necrotizing pancreatitis was diagnosed in 5 patients (12.2%), and recurrent acute pancreatitis in 4 patients (9.8%). CT findings included pancreatic swelling (43.9%), peripancreatic fluid collection (29.3%), ascites (24.4%), and peripancreatic fat necrosis (12.2%). Serum amylase and lipase levels at diagnosis were 535.3${\pm}$553.2 and 766.2${\pm}$723.6 U/L, respectively, and were normalized within 1 week in 22 and 14 patients, respectively. On the basis of the Balthazar scale, 2 patients were diagnosed with severe AP. In 4 patients (9.8%), a surgical procedure was indicated. Major complications included ascites (32.3%), sepsis (16.1%), and pseudocyst and renal impairments (12.9%). Two patients died from multi-organ failure. Conclusion: The etiologies of AP in children are varied. Most children have a single episode and a self-limited course. However, AP of childhood still carries significant morbidity and mortality. Early diagnosis, appropriate treatment according to disease severity, and management of complications are important.

Background: Breast cancer is the most frequent type of cancer among women in the world and the most common cause of deaths from cancer in females. In Turkey, breast cancer comes first in the list of the most frequent ten cancer types seen in women. As the incidence rate of breast cancer is high, many women having breast cancer in the family experience the breast cancer at secondhand. This study was carried out in an attempt to determine the information and support needs of women whose first-degree relatives have breast cancer and to what extent these needs are met. Methods: The research sample consisted of 156 women. Questionnaire Form and Information and Support Needs Questionnaires were used as the data collection tools. Results: Information need score averages ($x^-:3.72{\pm}0.19$) of women included in the research sampling were found to be higher than their score averages of support needs ($x^-:3.24{\pm}0.41$). Conclusion: Information needs which were indicated by women as very important were related to treatment, symptoms of breast cancer and breast self examination (BSE), while support needs which were indicated by women as very important were learning how to perform BSE, women's anxiety for themselves and their relatives regarding breast cancer and having their breasts examined by a health professional. It is recommended that nurses and other medical staff should give information to women whose first-degree relatives have breast cancer about the disease, its etiology, scanning, diagnosis, treatment options and protection as well as prevention.

Purpose: This study aimed to evaluate the impact of a lifestyle modification program on menstrual irregularity among overweight and obese women with polycystic ovarian syndrome. Methods: A quasi experimental research design was used to conduct this study on 82 women with polycystic ovarian syndrome at the Gynecology and Obesity clinics of Mansoura University Hospital, Egypt. Two groups were included; the study group received a lifestyle modification program for 48 weeks, while the control group was not subjected to this program. Data collection was done for the following variables, a structured interview questionnaire was used to assess the women's general characteristics, menstrual patterns, and 24-hour dietary recall and the researcher took anthropometric measurements and assessed hirsutism by the Ferriman-Gallwey scale. Results: After one year of lifestyle modification, the number of menstrual cycles significantly increased from $2.7{\pm}1.6$ to $6.9{\pm}1.5$ (t=12.26, p<.001) in the study group compared to insignificant minor changes among the control group (t=0.69, p=.488). Additionally, 58.5% were menstruating regularly compared to none in the control group (${\chi}^2=33.93$, p<.001). Conclusion: Participating in a lifestyle modification program was effective in reducing menstrual cycle's irregularity among overweight and obese women with PCOS. Thus, it is recommended to motivate the nurses in counseling the PCOS women on lifestyle modifications.

Purposes: Pancreatic injury is rare in abdominal trauma patients (3%~12%). but it could result in significant morbidity and even mortality. Early and adequate decision making are very important in the management of patients with traumatic pancreatic injury. The purpose of this study was to assess the kinds of management and outcome through the review of our experience of pancreatic injury with multiple trauma. Methods: We reviewed 17 patients with traumatic pancreas injury via electronic medical records from Jan. 2002 and April. 2011. We collected demographic findings; the type, location and grade of pancreas injury, the treatment modality, and patient's outcomes, such as complications, length of hospital stay (LOS), and mortality. Results: Total 17 patients were reviewed, and man was 13 (88%). Traffic accident was the most common cause of injury. Pancreas neck was the most common injured site, and occured in 5 patients. Ductal injury was detected in 7 cases. Eleven patients were treated by surgical procedure, and in this group, 3 patients underwent the endoscopic retrograde pancreas drainage procedure coincidently. ERPD was tried in 8 patients, and failed in 2 patients. The major complications were post-traumatic fluid collection and abscess which accounted for 70 % of all patients. The hospital stay was 35.9 days, and it was longer in patient with ductal injury ($38.0{\pm}18.56$ vs. $34.5{\pm}33.68$ days). Only one patient was died due to septic shock associated with an uncontrolled retroperitoneal abscess. Conclusion: Early diagnosis is the most important factor to apply the adequate treatment option and to manage the traumatic pancreas injury. Aggressive treatment should be considered in patients with a post-operative abscess.

The present study was carried out for the comparative study on the collection of bovine follicular oocytes by ultrasound-guided ovum pick-up(OPU) and slaughterhouse-derived (SHD) ovary aspiration and in vitro production of bovine embryos with the follicular oncytes in Korean native cows. Bovine follicular nocytes were observed with a 6.5 MHz convex-array ultrasound transducer designed for intravaginal use and the oocytes were collected with the aspiration equipment attached to the ultrasonograph. Bovine ovaries were collected and transported in phosphate buffered saline from the local slaughterhouse, the follicular oocytes were collected by the aspiration method. The collected follicular oocytes in good quality were matured, fertilized and cultured in the media. The total number of the visible follicles and the recovery rate of follicular oocytes were increased in ultrasonography following follicle stimulating hormone(FSH) treatment in Korean native cows. The mean recovery rate of oocytes was 66.2, 52.8 and 41.7% in the FSH-OPU, non-treatment-OPU and SHD ovaries, respectively. The mean number of recorved oocytes per cow were not significantly(P<0.05) different between the FSH-OPU(14.0$\pm$11.54) and SHD(17.1i6.21) groups, but the numbers in both groups were significantly(P<0.05) higher than the number in the non-treatment-OPU(3.7$\pm$1.57) group. The mean number of usable nocytes in Grade T /11 per ovary was 6.3, 4.8 and 1.3 in the cows of the SHD, FSH-OPU and non-treatment-OPU groups, respectively. The in vitro developmental rate to the blastocyst was not significantly different between the oocytes obtained via OPU(37.1%) and SHD(29.3%). Therefore, the ultrasound-guided OPU technique can be applied to the production of excellent embryos from the high-quality cows, and for the large scale production of in vitro bovine oocytes and embryos, the SHD ovary aspiration method is valuable.

Thermal diode is a device which allows heat to be transferred in one direction by convection due to difference of density of fluid, and blocks heat flow in the opposite direction. Vertical plate for heat collection and radiation are of utility for design of thermal diode. It was considered the transient and steady state of air filled thermal diode with guide vane which combined rectangular and parallelogrammic shape enclosures. $Gr^*$ was kept constantly on $1.11{\times}10^{10}{\sim}1.4{\times}10^{10}$ and error range was ${\pm}3%$ during the experiment. Nu was examined when inclined angle are $15^{\cir\c}\;and\;45^{\circ}$ and, also the experiments was carried out with and without guide vane as well. Specially, Nu was linearly increased due to increase of $Gr^*$, and the effect of guide vane and dimensionless channel depth was sensitive. Developed state of temperature began at dimensionless time $0.5{\sim}0.6$ due to variation of inclined angle, which is characteristic of system.

Attention Deficit Hyperactivity Disorder (ADHD) is one of the most general childhood problems occurs locally and internationally, but the causes of ADHD are not cleared yet. Therefore, this study tried to examine some parts of the causes of ADHD closely, and finally contribute to the medical treatment of ADHD and its precautionary measures, by measuring and comparing concentration of minerals in hairs of the patients of ADHD and their control group's children. which can analyze the relevance to ADHD and the mineral content in human bodies, and mutual relations between toxic minerals and essential minerals in human bodies. After collection of hairs from 200 children(5 to 7-year-old, boys: 159 girls:41) diagnosed as ADHD by medical specialists based on the standard of DSM-IV diagnosis and their control group's 177 children(boys: 138 girls:39), the mineral concentration of samples was measured through ICP-MS and compared. And correlations between toxic minerals and essential minerals in human bodies among patients group was analyzed. All the toxic minerals(Pb, Hg, Al, Cd, As) of hairs analyzed in the study showed more higher range of concentration in patients group in comparison with their control group. Among them, the concentration of Pb(3.27 $\pm$ 3.82 ppm) and As(0.16 $\pm$ 0.15 ppm) in patients group were significantly high compared to their control group. And in this study Pb among toxic minerals showed negative correlation with Zn(r = -0.43), Mg(r = -0.15) among essential minerals. Cd among toxic minerals showed negative correlation with Zn(r = -0.20) among essential minerals. As among toxic minerals showed negative correlation with Ca(r = -0.14) among essential minerals.

Purpose: The aim of this study was to examine the validity and reliability on Psychometric Arthritis Impact Measurement Scale-Short Form (AIMS-SF) in patients with knee osteoarthritis(OA). Methods: The sample consisted of 62 patients who had received physical therapy at the physical therapy units of the Andong Medical Center, Sungso Hospital, Ahn Orthopedic Surgery Clinic, and St. Luke Clinic in Andong city in June 2006. Questionnaire on the AIMS-SF was recruited by 5 physical therapists. The internal structure and reliability of the scales were evaluated by means of item-internal consistency(Cronbach's alpha coefficient: ${\alpha}$), item-discriminant validity, Pearson's relation coefficient. To explore construct validity we conducted a principal component factor analysis with varimax rotation analysis. The criterion for factor extraction was an eigenvalue >1.0. Results: 62 OA patients's an average $age{\pm}standard$ deviation was $53.8{\pm}14.4$ years (range: $40{\sim}81$ yr). The internal consistency reliability of 11 items, as estimated by Cronbach's ${\alpha}$ coefficient, was high ranging $0.60{\sim}0.78$ (except for 0.40 for mobility level and -0.48 for mood). The internal consistency reliability of item-each scale was also high $0.82{\sim}0.93$ (except for 0.48 for mood). Of 11 items, the item-discriminant validity on 6 items was high (${\alpha}$ coefficient range: $0.11{\sim}0.25$), however, others (0.57 for tension level, 0.48 for arthritis pain, 0.41 for walking and bending, and 0.40 for work) were a little low. The construct validity by factor analysis was a little low. Conclusion: In conclusion, the results reported here confirm the validity and reliability of the AIMS-SF in patients with OA of the knee. The Collection of information on health status using this instrument was acceptable to patients. A further prospective multi-center study will be necessary to prove the construct validity.

We have screened 766 strains of fungi from the BIOTEC Culture Collection (BCC) for xylanases working in extreme pH and/or high temperature conditions, the so-called extreme xylanases. From a total number of 32 strains producing extreme xylanases, the strain BCC7928, identified by using the internal transcribed spacer (ITS) sequence of rRNA to be a Marasmius sp., was chosen for further characterization because of its high xylanolytic activity at temperature as high as $90^{\circ}C$. The crude enzyme possessed high thermostability and pH stability. Purification of this xylanase was carried out using an anion exchanger followed by hydrophobic interaction chromatography, yielding the enzyme with >90% homogeneity. The molecular mass of the enzyme was approximately 40 kDa. The purified enzyme retained broad working pH range of 4-8 and optimal temperature of $90^{\circ}C$. When using xylan from birchwood as substrate, it exhibits $K_m$ and $V_{max}$ values of $2.6{\pm}0.6\;mg/ml$ and $428{\pm}26\;U/mg$, respectively. The enzyme rapidly hydrolysed xylans from birchwood, beechwood, and exhibited lower activity on xylan from wheatbran, or celluloses from carboxymethylcellulose and Avicel. The purified enzyme was highly stable at temperature ranges from 50 to $70^{\circ}C$. It retained 84% of its maximal activity after incubation in standard buffer containing 1% xylan substrate at $70^{\circ}C$ for 3 h. This thermostable xylanase should therefore be useful for several industrial applications, such as agricultural, food and biofuel.
