This study aims to provide basic size data for the development of a hip dislocation prevention garment for cerebral palsy (CP) children and useful information for the design of garment products for CP children through identifying differences in body shape between CP and non-CP children and reviewing the tibial-stature prediction formulas of previous studies. Forty-seven Korean children with CP aged 2 to 14 years were measured for body size from October 2019 to August 2020. Body measurements of 18 sites, including greater trochanter length, which is an important site for a hip dislocation prevention garment, were collected and analyzed. Data of non-CP children were taken from same age of Size Korea and compared. Tibial-stature prediction formulas suggested in four previous studies were also reviewed. CP children had significantly lower stature as well as circumferential dimensions when compared to non-CP children. Greater trochanter length is difficult to predict through other body dimensions. Thus, direct measurement is required. Of the general key dimensions used in the clothing industry, only hip circumference could explain the body shape of CP children. Tibial-stature prediction formulas cannot always but tend to largely predict the actual stature of CP children.

Enzyme-linked immunosorbent assay (ELISA) for assaying the 5-enolpyruvyshikimate-3-phosphate synthase from Agribacterium sp. CP4 (CP4 EPSPS) in genetically modified soybeans was developed. Polyclonal and monoclonal antibodies (Pab, Mab) specific to the CP4 EPSPS were produced. When using the Pab, the detection limit of sandwich ELISA toward CP4 EPSPS (0.03 ${\mu}g/mL$) was better than that of competitive indirect ELISA(ciELISA) (1 ${\mu}g/mL$). It was found that 2 of 3 monoclonal antibodies, Mab1 and Mab2, recognized the same antigenic determinant on CP4 EPSPS, but Mab3 recognized different antigenic determinant when competitive ELISA was performed using the Mabs. On the other hand, when the sensitivity of sandwich ELISA using combination of Pab and/or Mabs was determined, the sandiwich ELISA using Mab2 as a capture antibody and Pab-HRP as a secondary antibody showed the lowest detection limit of CP4 EPSPS (0.02 ${\mu}g/mL$). The sandwich ELISA developed in this study could be applied to detect glyphosate-tolerant soybeans.

This experiment was conducted to determine crude protein requirements for maintenance (CPm) of growing Hanwoo steers. Eighteen Hanwoo steers (173.7kg) were allocated randomly to diets with three levels of crude protein in the concentrate by replacing ground corn with corn gluten meal: 0% (LCP), 7.2% (MCP) and 14.2% (HCP), respectively. Hanwoo steers in each treatment were fed diets containing rice straw (20%) and concentrates (80%). CP intake was 5.5, 7.8 and 10.7g/BW0.75 for LCP, MCP and HCP, respectively. Protein balance was －0.05, 2.36 and 4.07g/BW0.75 for LCP, MCP and HCP, respectively. Intercept of the regression equation between CP intake and retained CP indicated that CPm was 5.56g/BW0.75. The estimate of CPm adopted by Korean Feeding Standard (2002) was almost 20% higher than that adopted by Japanese Feeding Standard for Beef Cattle (2000); this would need to be verified with more feeding trial data set including protein requirements for growth.

The changes in adenosine triphosphate (ATP), creatine phosphate (CP) and lactic acid (LA) contents of guinea pig hearts were studied during the cardioplegia and recovery phase. 1) ATP and CP contents in cardiac ventricular tissue were decreased during the cardioplegia, regardless of $Ca^{2+}$ concentration in the cardioplegic solutions, and CP contents were recovered with the reperfusion of normal Tyrode solution faster than those of ATP. And there were no significant differences in the recovery of CP contents with different concentration of $Ca^{2+}$ in the cardioplegic solutions tested, while the recovery of ATP contents was faster with 15 mM $K^{+}$, 0.1 mM $Ca^{2+}$ cardioplegic solutions. 2) LA contents were increased during the cardioplegia and decreased with the reperfusion of normal Tyrode solution. 3) The more recovery time (up to 3 hrs), the more CP contents were recovered with the reperfusion of normal Tyrode solution faster than those of ATP. And LA contents were decreased as the duration of recovery time. These results suggest that $Ca^{2+}$ and $K^{+}$ concentration in the cardioplegic solution is one of the major factors influencing the recovery of cardiac tissue from the cardioplegia.

Dietary conjugated linoleic acid(CLA) has been shown to affect immune function. Thus, the objective of this study was to investigate the effects of CLA on the mice that treated prednisone. Mice were randomized into 6 groups and fed diet containing either 0(control, P), 0.5%(CLA1, CP1) or 1.5%(CLA2, CP2) CLA for Sweets. Before 1 week of finishing diet supplement CP1, CP2, and P group treated the prednisone by subcutaneous injection. The levels of serum immunoglobulin A, G, E, gut lumen s-IgA, MLN immunoglobulin A, body weight, mucosal protein was compared. The level of serum IgA in CLA1, CLA2, CP1, and CP2 group increased, while which of P group was decreased. The level of serum IgG in CLA 1 group increased, while which of the other group no differences. Serum IgE level showed no difference and the immunoglobulin production in MLN lymphocyte in CLA 1 group increased. The level of gut lumen s-IgA in P group showed decreased, while which of the other group showed no differences. These results support the view that CLA supplement partially enhance the cell-mediated immunity and overcome the immunosuppressive effect of prednisone.

This experiment was conducted to investigate the effects of dietary bacteriophage CP supplementation on growth performance, nutrient digestibility, blood profiles, visceral organ weight, meat quality and fecal microflora in broilers. A total of 340 1-d-old ROSS 308 broilers (mixed gender) with an initial average body weight (BW) of $41.14{\pm}0.17g$ were randomly allotted to 4 treatments with 5 replicate pens per treatment and 17 broilers per pen for 31 days. Dietary treatments were: 1) CON, control diet, 2) CP05, CON + 0.05% bacteriophage CP, 3) CP10, CON + 0.10% bacteriophage CP and 4) CP15, CON + 0.15% bacteriophage CP. During d 15 to d 31, broilers fed CP15 diet had higher (P<0.05) body weight gain and feed intake than broilers fed CON diet. Overall, body weight gain in CP10 and CP15 treatment groups was greater (P<0.05) than that in CON treatment and feed intake was higher (P<0.05) in CP15 treatment than that in CON. Apparent total tract nutrient digestibility and blood characteristics did not differ (P>0.05) among treatments. The water holding capacity of breast meat increased (P<0.05) in broiler fed the diets containing bacteriophage CP compared with those fed the CON diet. Other meat characteristics such as pH value, breast muscle color ($L^*$, $a^*$, $b^*$) and drip loss were unaffected by dietary supplementation of bacteriophage CP. The weight of bursa of Fabricius increased (P<0.05) in CP05 when compared with CON. No significant difference was observed (P>0.05) among treatments in visceral weight and fecal microflora concentrations of Lactobacillus spp., Clostridium perfringens, Escherichia coli and Salmonella spp. In conclusion, dietary supplementation with 0.10 and 0.15% bacteriophage CP could improve the growth performance.

Atopic dermatitis (AD) is a chronic inflammatory skin disease and the pathogenesis of AD is associated with the release of various cytokines/chemokines due to activated $Th_2$ immune responses. Synthetic oligodeoxynucleotides (ODNs) containing unmethylated CpG dinucleotide in the context of particular base sequence (CpG motifs) are known to have the immunostimulatory activities in mice and to convert from Th2 to Th1 immune responses in AD. We aimed to investigate that CpG ODN, especially phosphodiester form, can stimulate the protective immunity in NC/Nga mice with AD. We isolated BMDCs from NC/Nga mice and then, cultured with GM-CSF and IL-4 for 6 days, and treated for 2 days by either phosphorothioate ODN or phosphodiester ODN. CpG ODN-treated DCs resulted in more production of IL-12. When CpG ODN-treated DCs were intravenously injected into the NC/Nga mice, the NC/Nga mice with CpG ODN-treated DCs showed significant improvement of AD symptoms and decrease of IgE level. Histopathologically, the NC/Nga mice skin with CpG ODN-treated DCs showed the decreased IL-4 and TARC expression comparing with non-injected mice. These results may suggest that phosphodiester CpG ODN-treated DCs might function as a potent adjuvant for AD in a mouse model.

Synthetic pyrethroids (SPs) are the most common pesticides which are recently used for indoor pest control. The widespread use of SPs has resulted in the increased exposure to wild animals and humans. Recently, some SPs are suspected as endocrine disrupting chemicals (EDCs) and have been assessed for their potential estrogenicity by adopting various analyzing assays. In this study, we examined the estrogenic effects of lambda-cyhalothrin (LC) and cypermethrin (CP), the most commonly used pesticides in Korea, using BG-1 ovarian cancer cells expressing estrogen receptors (ERs). To evaluate the estrogenic activities of two SPs, LC and CP, we employed MTT assay and reverse-transcription polymerase chain reaction (RT-PCR) in LC or CP treated BG-1 ovarian cancer cells. In MTT assay, LC ($10^{-6}M$) and CP ($10^{-5}M$) significantly induced the growth of BG-1 cancer cells. LC or CP-induced cell growth was antagonized by addition of ICI 182,720 ($10^{-8}M$), an ER antagonist, suggesting that this effect appears to be mediated by an ER-dependent manner. Moreover, RT-PCR results showed that transcriptional level of cyclin D1, a cell cycle-regulating gene, was significantly up-regulated by LC and CP, while these effects were reversed by co-treatment of ICI 182,780. However, p21, a cyclin D-ckd-4 inhibitor gene, was not altered by LC or CP. Moreover, $ER{\alpha}$ expression was not significantly changed by LC and CP, while down-regulated by E2. Finally, in xenografted mouse model transplanted with human BG-1 ovarian cancer cells, E2 significantly increased the tumor volume compare to a negative control, but LC did not. Taken together, these results suggest that LC and CP may possess estrogenic potentials by stimulating the growth of BG-1 ovarian cancer cells via partially ER signaling pathway associated with cell cycle as did E2, but this estrogenic effect was not found in in vivo mouse model.

Plakoglobin (PKG) is a protein linking cadherin adhesion receptors to the actin cytoskeleton and its overexpression has been known to suppress cell proliferation and tumorigenesis in thyroid cancer. We investigated the effect of 5-aza-2'-deoxycytidine (5-Aza-CdR), a DNA methyltransferase inhibitor, on the methylation status of the promoter and the expression of the plakoglobin gene in a thyroid carcinoma cell line (ARO) and papillary thyroid carceinoma. In cultures of ARO cell line incubated without 5-Aza-2'-deoxycytidine (5-Aza-CdR), five of the fifteen CpG sites in the promoter spanning -225 and -54 were methylated at 4.2 - 12.5%. When the cells were treated with 5-Aza-CdR, all the methylated CpG sites were induced to be demethylated except one. In addition, a new methylation at one CpG site, CpG4, was identified at level of 12.0%. The expression level of PKG decreased approximately 10-fold in the 5-Aza-CdR treated cells compared to untreated cells. Different pattern of promoter methylation and expression of PKG was also observed in the tissue samples. CpG10 and CpG12 sites were methylated at 9.0-27.0% in normal tissues. However, in cancer tissues, CpG5 and CpG10 sites were methylated at 10.0-22.0%. Three of ten normal thyroid tissue samples and one of thirteen papillary carcinoma tumor samples showed increased PKG mRNA expression level. PKG protein expression analyzed by the immunohistochemical staining showed higher expression in the tumor compared with normal.
