In this study, the immunomodulatory activity of oligopeptide (CP) derived from solid-state fermented cottonseed meal were investigated in immunosuppressed BALB/c mice models by treatment with cyclophosphamide (CY). Results indicated that oligopeptide increased the thymus and spleen indices of CY-treated mice. The count of plague forming cells (PFC) and the content of half serum hemolysis ($HC_{50}$) in immunosuppressive mice were restored to the normal level in CP-10 and CP-20 groups while the cytokines interleukin (IL)-2, IL-6, and tumor necrosis factor alpha (TNF-${\alpha}$) were increased significantly in CP-20 group. Similar increasing the immunoglobulin of IgG and IgM content in the serum of CP-10 group were also observed. These findings indicated that oligopeptide derived from solid-state fermented cottonseed meal had a strong immune-enhancing activity as well as a protective effect against immunosuppression induced by cyclophosphamide in mice.

목 적 : 알레르기 환자와 정상인에서 형질세포양 수지상세포의 분포, TLR9 mRNA 양과 $IFN-{\alpha}$의 분비능에 차이가 있는지 알아보고자 하였다. 방 법 : 19명의 알레르기 환자와 17명의 건강한 성인을 대상으로 하였다. 말초혈액단핵세포를 채취하여 Lineage Cocktail(CD3, CD14, CD16, CD19, CD20, CD56)음성, HLA-DR 양성이면서 CD123양성을 유세포 분석기로 분석하였다. 말초혈액단핵세포에 TLR9 작용제(agonists)인 CpG-ODN 2216과 음성 대조를 위해 CpG-ODN 2206으로 자극하고 24시간 후 상청액을 추출하여 $IFN-{\alpha}$의 농도를 측정하였다. 또한 real time RT-PCR을 이용하여 TLR9 mRNA 정량분석을 시행하였다. 결 과 : 말초혈액단핵세포에서 형질세포양 수지상세포의 분포는 알레르기 환자가 평균 $0.1{\pm}0.04%$, 대조군이 평균 $0.25{\pm}0.23%$이었다. TLR9 mRNA 상대적인 양을 나타내는 ${\Delta}{\Delta}Ct$는 알레르기 환자에서 $1.29{\pm}0.41$이었고 대조군은 $1.25{\pm}0.23$이었다. TLR9 리간드인 CpG-ODN 2216 자극에 따른 $IFN-{\alpha}$의 분비능은 알레르기 환자에서 $911{\pm}829pg/mL$ 이었고 대조군에서 $1,095{\pm}888pg/mL$ 이었다. 이 세 결과에서 통계적인 차이는 없었다. 결 론 : TLR9을 통한 신호전달이 알레르기 환자의 면역반응을 대표하지는 않는 것으로 보이며, 향후 더 자세한 TLR9의 역할에 대한 연구가 필요하다.

This experiment was conducted to evaluate the effect of dietary energy and crude protein (CP) levels on growth performance, blood profiles, and carcass traits in growing-finishing pigs. A total of 180 crossbred pigs ([Yorkshire ${\times}$ Landrace] ${\times}$ Duroc) with an average body weight of $30.96{\pm}3.068kg$ were used for a 12-week feeding trial. Experimental pigs were allotted to a $2{\times}3$ factorial arrangement using a randomized complete block (RCB) design. The first factor was two levels of dietary metabolizable energy (ME) density (13.40 MJ/kg or 13.82 MJ/kg), and the second factor was three dietary CP levels based on subdivision of growing-finishing phases (high: 18%/16.3%/16.3%/13.2% middle: 17%/15.3%/15.3%/12.2% and low: 16%/14.3%/14.3%/11.2%). Average daily gain (ADG) and gain-feed ratio (G:F ratio) decreased as dietary CP level was decreased linearly (linear, p < 0.05; p < 0.05, respectively) in the early growing period, and G:F ration also decreased as dietary CP level was decreased linearly (linearly, p < 0.05) over the whole growing phase. Over the entire experimental period, G:F ratio decreased as dietary ME level decreased (p = 0.01). Blood urea nitrogen (BUN) concentration was increased as dietary energy level decreased in growing period (p < 0.01). During finishing period, total protein concentration was decreased by lower dietary energy level (p < 0.05). In this study, there were no significant differences in proximate factors, physiochemical properties, muscle TBARS assay results, pH changes, or color of pork by dietary treatments. However, saturated fatty acid (SFA) increased (p < 0.01) and polyunsaturated fatty acid (PUFA) decreased (p < 0.05) when ME was decreased by 0.42 MJ/kg in growing-finishing pig diets. In addition, monounsaturated fatty acid (MUFA) tended to increase when CP level was decreased in growing-finishing pig diets (p = 0.06). A growing-finishing diet of 13.82 MJ/kg diet of ME with the high CP level can improve growth performance and show better fatty acids composition of pork.

To obtain the immunomodulating polysaccharide from chaga mushroom (Inonotus obliquus sclerotia, IO), crude polysac- charide fractions (IO-M-CP and IO-CP, respectively) prepared from hot-water extract (IO-W) of I. obliquus by EtOH precipitation after MeOH reflux or not. After IO-W was re-dissolved in water followed by EtOH addition in the case without MeOH reflux, EtOH mixture was fractionated into EtOH-soluble (IO-E) and crude polysaccharide (IO-CP). In the meanwhile, MeOH-soluble fraction (IO-M) was separated from IO-W after MeOH reflux. The residue was dissolved in water and was added by EtOH, and then EtOH mixture was also fractionation into EtOH-soluble (IO-M-E) and crude polysaccharide (IO-M-CP). As a result of the macrophage stimulating activity of these fractions, IO-CP and IO-M-CP showed significantly increased cell proliferation and cytokines production than IO-W. Particularly, IO-M-CP promotes the production of IL-12 more than IO-CP. In the splenocytes proliferating activity and intestinal immune system modulating activity through Peyer's patch, both of 2 crude polysaccharide fractions were significantly promoted in cell proliferation and cytokines production than IO-W, and IO-M-CP was more potent than IO-CP in IL-2 production from splenocytes and GM-CSF production ($10{\mu}g/mL$) in Peyer's patch cells. In addition, immunomodulating polysaccharide fractions (IO-M-CP and IO-CP) prepared from IO-W by EtOH precipitation with or without EtOH reflux showed no significant difference in the chemical composition and component sugar. These results suggested that MeOH reflux might exclude low-molecular weight materials from IO-W and consequently increase the immunomodulating activity of IO-M-CP. Therefore, it was confirmed that immunomodulation of polysaccharide prepared from hot-water extract of chaga mushroom was enhanced by fractionation including MeOH reflux and EtOH precipitation.

This experiment was conducted to study the effects of chromium (Cr), dietary crude protein (CP) level and potential interactions between these two factors on growth rate and carcass response, insulin activity and lipid metabolism in lambs. Forty-eight, 9-week-old weaned lambs (Dorper$\times$Small-tail Han sheep, mean initial body weight = $22.96kg{\pm}2.60kg$) were used in a $2{\times}3$ factorial arrangement of supplemental Cr (0 ppb, Cr0; 400 ppb, Cr1; or 800 ppb, Cr2 from chromium yeast) and CP levels (157 g/d to 171 g/d for each animal, LP; or 189 g/d to 209 g/d for each animal, HP). Growth data and blood samples were collected at the beginning and end of the feed trial, after which the lambs were killed. Both Cr additive groups and the HP group increased final weight and average daily gain, especially the Cr1 and HP group (p<0.01). HP increased pelvic fat weight (p<0.05), fat thickness of the 10th rib (p<0.05), longissimus muscle area (p<0.01) and rate of deposition of intramuscular fat (p<0.01). Supplemental Cr decreased the rate of deposition of intramuscular fat (p<0.05). Fasting insulin level and the ratio of insulin to glucose were lower with Cr1 than other groups, but with no significant difference. Glucose concentration was not affected by any treatment. Nonesterified fatty acids increased in the Cr1 (p<0.05) and HP (p<0.05) conditions and there was a significant $Cr{\times}CP$ interaction (p<0.05). Cr1 decreased triglycerides (p<0.05) and total cholesterol (p = 0.151) and HP increased high-density lipoprotein cholesterol (p<0.05). Cr1 decreased lipoprotein lipase activity in subcutaneous adipose tissue (aLPL, p<0.05) and the ratio of aLPL to lipoprotein lipase activity in skeletal muscle (mLPL, p = 0.079). mLPL and hepatic lipase (hHL) were not affected by any treatment. In the present study, Cr had limited effects on growth rate and carcass response, whereas Cr and CP had some notable effects on plasma metabolites and enzyme activities. Cr has a potential effect on energy modulation between lipid and muscle tissue. In addition, few $Cr{\times}CP$ interactions were observed.

지난 10년 동안 인공지능의 도움으로 노화를 정량화하기 위한 수많은 연구가 수행되었다. DNA 메틸화 데이터를 사용하여 다양한 모델이 개발되었으며 흔히 후성유전학적 시계라고 불린다. 후성유전학적 나이 가속화는 일반적으로 질병 상태와도 주로 연관이 있어 보인다. 조현병은 가속 노화 가설과 관련있는 정신질병으로 심각한 정신적, 신체적 스트레스를 동반한다. 다른 심리 질환과 비교했을 때 이 질병은 젊은 사람들에서 높은 사망률과 질병률을 유발한다. 과거 연구에서는 이 질병이 가속 노화 가설과 연관있다고 알려져 있었다. 이번 연구에서는 조현병 환자의 후성유전학적 나이 가속도 변화를 통해 질병에 대한 후성유전학적 통찰을 얻고자 하였다. 후성유전학적 나이 가속화를 측정하기 위해 두 가지 다른 DNA 메틸화 시계 모델을 사용했으며 이는 범조직 모델인 Horvath clock과 Epi clock을 사용하였다. 우리는 Horvath clock과 Epi clock이 모두 호환되는 450k 어레이 데이터를 사용하였다. 그 결과, Epi clock을 사용했을 때 환자샘플에서 후성유전학적 나이 가속화가 더 느리다는 것을 발견했다. Epi clock이 질병으로 인한 DNA 메틸화 변화를 잘 감지해낼 수 있음을 알아내었다. 또한 Epi clock에서 대조군과 환자군에서 차등적으로 메틸화된 CpG 부위를 분석하고 경로 농축 분석을 수행한 결과, 대부분의 CpG가 신경 세포 과정에 관여한다는 사실을 발견했다.
