In this study, to evaluate the anti-obesity effects of mulberry leaf tea and its fermented product by Monascus pilosus, we investigated body and organ weight, blood and liver biomarkers in mice fed 1% tea infusions instead of water for 8 weeks. Mice were divided into three groups such as a normal control (NC), unfermented mulberry leaf tea infusion (UMI) and fermented mulberry leaf tea infusion (FMI). Although it is not significant, tea infusion groups showed reduction of body weight gains compared with NC group. Moreover, contents of LDL-cholesterol and lipid peroxide (LPO), altherogenic index, and xanthin oxidase (XO) activity were significantly decreased, and glutathione S-transferase (GST) activity was significantly elevated. The results from this study suggested that UMI and FMI may have an anti-obesity activity, upregulate antioxidant enzymes and reduce levels of oxidants related to liver damage.

This study was conducted to investigate the effect of a 3 week low calorie diet (LCD) and a 9 week of behavior modification (BM) program on the weight loss, mineral and vitamin status in 22 obese women. The subject were healthy, obese (PIBW> $120\%$) women aged 20 - 50 Yr and not taking any medications known to influence body composition, mineral or vitamin metabolism During the LCD program, subjects were provided commercial liquid formulas with 125 kcal per pack and were instructed to have a formula for replacement of one meal and at least one regular meal per day within the range of daily 800 - 1200 kcal intake. During the BM program the subjects weekly attended the group nutrition counseling session to encourage themselves to modify their eating behavior and spontaneously restrict their energy intakes. The BM program focused on stimulus control, control of portion sizes and modification of binge eating and other adverse habits. The initial mean energy intake of subjects was 2016.9 $\pm$ 129.8 kcal ($100.8\%$ of RDA) and dropped to 1276.5 $\pm$ 435.7 kcal at the end of a 3 week of LCD program and elevated to 1762 $\pm$ 329.3 kcal at the end of a 9 week of BM program. Carbohydrate, protein and fat intakes were significantly decreased at the end of the LCD but carbohydrate was the only macro nutrient that showed significant decrease (p < 0.05) at the end of the BM program compared to baseline. Calcium and iron intakes decreased significantly (p < 0.01, respectively) with no significant changes in other micronutrients at the end of the LCD. The mean weight of the subjects decreased from 73.8 $\pm$ 8.0 kg to 69.2 $\pm$ 7.7 kg with LCD and ended up with 67.7 $\pm$ 7.1 kg after 9 weeks of BM. The 3 weeks of LCD reduced most of the anthropometric indices such as BMI, PIBW, fat weight, wast-to-hip ratio and subscapular and suprailiac skinfold thickness. The 9 weeks of behavior modification showed slight change or maintenance of each anthropometric measurements. Weight loss and decreased WHR with the diet program induced significantly decreased systolic blood pressure. SGOT, SGPT and serum insulin levels with improved serum lipid profiles. Biochemical parameters related to iron status such as hemoglobin, hematocrit were significantly decreased (p < 0.01) at the end of the LCD. But their mean values were within normal range. The mean serum 25 (OH) vitamin $D_3$ level significantly increased after whole diet program. Serum folate level significantly decreased after 12 weeks of diet program. In conclusion 3 weeks of LCD brought 4.6 kg reduction in body weight without risk of iron, zinc or vitamin D deficiency and 9 weeks of the BM was effective to maintain nutritional status with slightly more weight reduction (1.5 kg). However calcium intake and serum folate should be monitored during the LCD and BM because of increased risk of deficiencies.

The study was undertaken to evaluate the effect of naked neck gene on mortality, cell mediated and humoral immune response in white plumage broiler population. The mortality of homozygous naked neck (Na/Na) broilers (11.71%) was comparatively lower than that of heterozygous naked neck (Na/na) (12.28%) and normally feathered (na/na) (13.59%) broilers. The humoral immune response was measured against (1% v/v) sheep red blood cells (SRBC) for total haemagglutinin (HA) antibody, 2-mercaptoethanol resistance (MER) or (IgG) antibody and 2-mercaptoethanol sensitive (MES) or (IgM) antibody titre on 7 days post-immunization. The titre was expressed as log2 of the highest dilution which shows complete haemagglutination. Total HA titers of Na/Na and Na/na (11.05$\pm$0.53 and 11.09$\pm$0.38) were comparatively higher than that of na/na (10.26$\pm$0.42). The MES antibody titre of Na/Na (8.50$\pm$0.53) and Na/na (7.63$\pm$0.45) broilers were significantly higher as compared to na/na (6.11$\pm$0.32) broilers. The MER titre of na/na genetic group (4.15$\pm$0.42) was significantly higher than Na/Na (2.55$\pm$0.37) and comparatively higher than Na/na (3.45$\pm$0.38) broilers. In vivo cell response to phytohaemagglutinin-P (PHA-P), measured as Foot Index (FI) in mm expressed significantly higher response in Na/na (0.473$\pm$0.05) and Na/Na (0.413$\pm$0.04) broilers as compared to na/na (0.304$\pm$0.03) broilers. The result of present study suggested that white plumage naked neck broilers had better immune response as compared to normally feathered broilers.

Rumen bypass fat is commonly added to increase energy intake in dairy cattle. The objective of this study is to examine the addition of rumen bypass fat during finishing period on performance and carcass characteristics in grain fed steers. This study was conducted as a completely randomized block design with 126 cross-bred steer calves (initial BW $471.5{\pm}7.5kg$) randomly assigned to pens with 9 steers/pen (n = 7 pens/treatment). Each pen was randomly assigned to one of two treatment groups; rumen bypass fat treatment (CCS, calcium soap of palm fatty acids) and control diet (CT, tallow). The diets were formulated to be isonitrogenous and isocaloric. Animals were fed twice daily at 110 % of the previous daily ad libitum intake. Blood from each sample was taken from the jugular vein. Muscle and adipose samples were collected from the longissimus dorsi regions. Feedlot performance and carcass characteristics were assessed. To examine adipogenic gene expression, quantitative real-time PCR was completed. Steers fed the CT had a greater level of performance for most of the parameters measured. The CT group had greater DMI (P < 0.05) and tended to have greater ADG (P < 0.10). Marbling score (P < 0.05) and quality grade (P < 0.05) were greater for steers fed the CT diet than those fed CCS. The longissimus muscle area tended to be greater (P < 0.10) in steers fed CT ($87.60cm^2$) than those fed CCS (84.88 cm2). The leptin mRNA expression was down-regulated (P < 0.05) in adipose tissue of steers fed a CCS when compared to those fed CT. These data suggest that calcium soap of palm fatty acids can be added to finishing diets without significant reduction in final body weight, although there may be modest reductions in marbling and quality scores.

Purpose: This study was conducted to confirm the anatomic conformity of the new periarticular locking plates designed by Zimmer on Korean adult bones and to identify the structures at risk during the application of these implants. Methods: The study was performed on the humerus, radius, and tibia of 10 adult cadavers(6 males and 4 females) procured from the cadaveric lab of our hospital. Anteroposterior (AP) and lateral X-rays were taken to confirm that the cadavers were free of any unusual lesions or anatomic variations. We used the 3.5-mm proximal humerus plate, 2.7-mm distal radius plate, 3.5- and 5.0-mm proximal tibia plates, and 3.5-mm distal tibia plate developed by Zimmer, Inc. (Zimmer periarticular locking plate). The longest plate from each group was used to confirm anatomical conformity. Standard approaches were used for each area, and soft tissue was retracted in order to pass the plate beneath the muscle. The position of the plate was confirmed using standard AP and lateral view X-rays. After this procedure had been completed, the region was dissected along the length of the implant to determine the conformity of the implant to bone and the penetrations of screws into the articular surface or violations of any vital structures, such as nerves, blood vessels, or tendons. Results: Excellent anatomical conformity was observed with Zimmer periarticular locking plates for Korean adults. The tibial nerve and the posterior tibial artery were found to be structures at risk when applying a distal tibial plate. Conclusion: Additional posterolateral fixation is recommended when dealing with cases of tibial plateau fracture when the fracture line extends to the posterolateral cortex. We recommend taking proper views using 10~15 degrees of internal rotation to ensure correct screw length and, thus, avoid penetration of vital structures and tendons.

Objective : The effects of Indium-Gallium-Aluminium-Phosphide(InGaAlP) laser transcutaneous irradiation on heart rate variability(HRV) in healthy adults are investigated with power spectrum analysis(PSA) of HRV. Methods : The control group consisted of 20 healthy volunteers (10 men, 10 women). The experiment was divided into 5 different periods, the pre-1st laser period(10 minutes), the 1st laser period(30 minutes), the post-1st laser period(5 minutes), the 2nd laser period( 30 minutes) and the post-2nd laser period(30 minutes). HRV was measured for 5 minutes at the pre-1 st laser period, the post-l st laser period and the post-2nd laser period. The laser period is the period in which InGaAlP laser transcutaneous Irradiation treatment occurs. Results : 1. SDNN of volunteers at post-1st laser period and post-2nd laser period significantly increased compared with that of the pre- 1 st laser period. 2, Ln(VLF) at post-I st laser period significantly increased compared with that of pre-1st laser period, while Ln(HF) at post-2nd laser period significantly decreased compared with those of pre- I st laser period and post-1st laser period, 3. Ln(TP) at post-1st laser period and post-2nd laser period significantly increased compared with that of pre-1st laser period, 4, LF/HF Ratio at post-2nd laser period significantly increased compared with those of pre-1st laser period and post-1st laser period. But the other variables did not significantly change. Conclusions : The results suggest that InGaAlp laser transcutaneous Irradiation in healthy adults is associated with the autonomic nervous systems. Further study is needed for investigating the effects of laser irradiation on autonomic nervous systems.

Recurrent bacterial meningitis is the reappearance of two or more episodes of meningitis caused by a different or same organism after an intervening period of full convalescence. Predisposing factors for recurrent bacterial meningitis include immunodeficiency and developmental and traumatic anatomical defects. Therefore, careful evaluation of children with recurrent meningitis is essential. We report the case of a patient with a skull base abnormality who had suffered from four events of bacterial meningitis between 8 and 17 years of age. He experienced another event of bacterial meningitis at the age of 21, without undergoing correction for the anatomical defect. Streptococcus agalactiae was identified in the patient's blood and cerebrospinal fluid culture. Afterwards, he underwent surgical treatment for a meningioma; this meningioma was strongly suspected as the cause of the recurrence.

Neisseria meningitidis is a leading cause of meningitis and septicemia in children and young adults. Meningococcemia, the most severe form of infection, represents a part of the various spectrum of the illness, and its clinical manifestations varied from mild fever and occult bacteriemia to fulminant catastrophic events(e.g., sepsis, shock, and death) within a few hours after onset of symptoms. Complement deficiencies, either congenital or acqired, increase the risk for invasive meningococcal disease. Since C3 plays a critical role in the complement cascade, congenital C3 deficiency or conditions that decrease C3(e.g., systemic lupus erythematosus, cirrhosis, nephritis, C3 nephritic factor) increase the risk for invasive disease due to pyogenic bacteria including N. meningitidis. We had experienced a case of meningococcemia and meningococcal meningitis presenting with mild fever, petechiae, and purpura. The patient was a 7-year old male. He had mild fever, vomiting, headache, nuchal rigidity, petechiae and purpura on both lower extremities, which spreaded to the whole body. His blood culture grew Neisseria meningitidis. The diagnosis of meningococcal meningitis was confirmed by examination of cerebrospinal fluid. The clinical symptoms of the illness were improved after treatment of antibiotics(cefotaxime) for 12 days. However the patient had developed generalized edema, microscopic hematuria & proteinuria on the third day after admission. High ASO titer and low serum C3 level were also noted. The microscopic hematuria returned to normal about 2 months after discharge. The C3 level returned to normal range about 3~4 months after discharge. we report a case of combined acute poststreptococcal glomerulonephritis and acute invasive meningococcal disease with reference review.

To determine if micronucleus (MN) assay could be used to predict the absorbed dose of victims after accidental radiation exposure, we carried out to assess the absorbed dose depending on the numerical changes of MN in human peripheral blood lymphocytes after $^{60}Co\;{\gamma}-rays$ exposure in the range of 0.25 to 1 Gy, respectively. The MNs were observed at very low doses, and the numerical changes according to doses. Satisfactory dose-effect calibration curve is observed after low dose irradiation of human lymphocytes in vitro. When plotting on a linear scale against radiation dose, the line of best fit was $Y=(0.02{\pm}0.0009)+(0.033{\pm}0.010)D+(0.012{\pm}0.012)D^2$. The dose-response curve for MN induction immediately after irradiation was linear-quadratic and has a significant relationship between the frequencies of MN and dose. These data show a trend towards increase of the numbers of MN with increasing dose. The number of MN in lymphocytes that were observed in the control group is $0.1610{\pm}0.0093/cell$. Accordingly, MN assay in human peripheral lymphocytes could be a useful in viva model for studying radio-protective drug sensitivity or screening test, microdosimertic indicator and radiation-induced target organ injury. Since MN assay is simple, rapid and reproducible, it will also be a biodosimetric indicator for individual dose assessment after accidental exposure.

Purpose: Vitamin $B_{12}$ and folic acid are type of water-soluble vitamin and those work as a secondary vital enzyme, but especially those are involved in the nuclear DNA synthesis. Those are mainly measured in order to diagnose megaloblastic anemia and to assess the storage of folic acid during pregnancy. It is generally known that the hemolyzed serum is useless for folic acid and vitamin $B_{12}$, but it is not easy to abide by this information because our lab (Samkwang Medical Laboratories) is reference laboratory. We tested how much the extent of hemolyzed serum had influence on the results. Materials and Method: We performed the tests of vitamin $B_{12}$, folic acid. For the hemolysis effect study, we used 40 cases. According to the level of A, B and C groups, each group had 10 samples which were mechanically hemolyzed serum. Results: Hemolysis did not affect the vitamin $B_{12}$ results. However in case of folic acid, the value increased according to the degree of hemolysis. And severe hemolyzed cases had the highest value (greater than 20 ng/ml). Conclusions: Preventing the hemolysis, it has to be informed that blood-collecting, separation and storage are performed more carefully. As you see from the above results, hemolyzed serum is not proper for folic acid test, and hemolysis does not affect the results of vitamin $B_{12}$. However, for the more accurate results, it is necessary to avoid hemolysis.
