  • Objectives : The purpose of this study is to investigate effects of Scutellariae Radix Water Extract on hydrogen peroxide production in RAW 264.7 mouse macrophages. Methods : Scutellariae Radix produced from South Korea (SK) and Scutellariae Radix produced from China (SC) were extracted by hot water. Effects of SK and SC on hydrogen peroxide production in RAW 264.7 were measured by dihydrorhodamine 123 assay after 2, 4, 20, 24, 28, 44, and 48 h incubation at the concentrations of 10, 25, 50, and 100 ug/mL. Results : SK significantly increase hydrogen peroxide production in RAW 264.7 cells for 2, 4, 20, 24, 28, 44, and 48 h incubation at the concentrations of 10, 25, 50, and 100 ug/mL (P < 0.05). SC also significantly increase hydrogen peroxide production in RAW 264.7 cells for 4, 20, 24, 28, and 48 h incubation at the concentrations of 10, 25, 50, and 100 ug/mL (P < 0.05). For 2 h incubation, SC significantly increase hydrogen peroxide production in RAW 264.7 cells at the concentrations of 10, 25, and 100 ug/mL (P < 0.05). For 44 h incubation, SC significantly increase hydrogen peroxide production in RAW 264.7 cells at the concentrations of 10, 25, and 50 ug/mL (P < 0.05). Conclusions : These results suggest that Scutellariae Radix has the immune - enhancing property related with its increasement of hydrogen peroxide production in macrophages.

  • 본 연구는 만삼추출분말의 모돈 사료 내 첨가급여가 모돈 및 자돈에 있어서 면역력과 생산성에 미치는 영향을 조사하기 위하여 실시하였다. 20두의 F1 임신돈(Landrace ${\times}$ Yorkshire)을 옥수수와 대두박을 기초로 하는 임신돈 기초사료 급여구와 만삼추출분말 0.5% 첨가 급여구로 나누어 각각 10두씩 배치하여 공시동물로 이용하였다. 실험사료를 분만예정일 40일 전부터 분만 후 이유 시(25일)까지 급여하였다. 만삼은 항산화 효과와 더불어 면역증강 효과가 있는 것으로 알려져 있어, 모돈 사료 내 만삼추출분말의 급여는 모돈의 면역능력을 증강시켜 결과적으로 자돈의 면역력 상승효과를 가져올 것으로 예상하였다. 또한 면역력 상승에 따른 보상효과로 자돈의 생산성 및 성장 촉진을 기대하였다. 본 연구의 결과에서는 만삼추출분말의 첨가급여가 모돈 및 자돈에 있어서 면역력과 생산성에 영향을 미치지 않는 것으로 나타났다. 초유 내 IgG 함량과 자돈 혈액 내 IgG 함량 사이의 상관관계는 유의적이지는 않았지만, 양의 상관관계(correlation coefficient, 0.435 P=0.102)를 나타내어, 초유 내면역력의 상승은 자돈에 이로운 영향을 미칠 수 있음을 시사하였다. 이상의 결과로부터, 면역항진 기능을 가진 만삼추출분말의 생리활성 물질은 임신 모돈의 생체 내에서 충분한 면역촉진효과를 나타내지 않은 것으로 사료된다. 따라서, 면역증강제로써 임신돈 사료 내 만삼추출분말의 이용 가능성을 평가하기 위해서는, 만삼추출분말 내 생리활성 물질의 생체내 대사 메커니즘과 작용기전을 검토할 필요가 있는 것으로 판단된다.

  • Objective: The objective of this study was to examine the effects of alfalfa flavonoids on the production performance, immunity, and ruminal fermentation of dairy cows. Methods: The experiments employed four primiparous Holstein cows fitted with ruminal cannulas, and used a $4{\times}4$ Latin square design. Cattle were fed total mixed ration supplemented with 0 (control group, Con), 20, 60, or 100 mg of alfalfa flavonoids extract (AFE) per kg of dairy cow body weight (BW). Results: The feed intake of the group receiving 60 mg/kg BW of AFE were significantly higher (p<0.05) than that of the group receiving 100 mg/kg BW. Milk yields and the fat, protein and lactose of milk were unaffected by AFE, while the total solids content of milk reduced (p = 0.05) linearly as AFE supplementation was increased. The somatic cell count of milk in group receiving 60 mg/kg BW of AFE was significantly lower (p<0.05) than that of the control group. Apparent total-tract digestibility of neutral detergent fiber and crude protein showed a tendency to increase (0.05<$p{\leq}0.10$) with ingestion of AFE. Methane dicarboxylic aldehyde concentration decreased (p = 0.03) linearly, whereas superoxide dismutase activity showed a tendency to increase (p = 0.10) quadratically, with increasing levels of AFE supplementation. The lymphocyte count and the proportion of lymphocytes decreased (p = 0.03) linearly, whereas the proportion of neutrophil granulocytes increased (p = 0.01) linearly with increasing levels of dietary AFE supplementation. The valeric acid/total volatile fatty acid (TVFA) ratio was increased (p = 0.01) linearly with increasing of the level of AFE supplementation, the other ruminal fermentation parameters were not affected by AFE supplementation. Relative levels of the rumen microbe Ruminococcus flavefaciens tended to decrease (p = 0.09) quadratically, whereas those of Butyrivibrio fibrisolvens showed a tendency to increase (p = 0.07) quadratically in response to AFE supplementation. Conclusion: The results of this study demonstrate that AFE supplementation can alter composition of milk, and may also have an increase tendency of nutrient digestion by regulating populations of microbes in the rumen, improve antioxidant properties by increasing antioxidant enzyme activities, and affect immunity by altering the proportions of lymphocyte and neutrophil granulocytes in dairy cows. The addition of 60 mg/kg BW of AFE to the diet of dairy cows was shown to be beneficial in this study.

  • An experiment was conducted to study the performance, carcass traits, serum lipid profile and immune competence in commercial broilers (2 to 42 d of age) fed graded levels (25, 50, 75 and 100%) of finger millet (FM) (Elusine coracana) in place (w/w) of yellow maize (YM). Each diet was fed to eight replicates (five female Vencobb broilers/replicate) housed in stainless steel battery brooders. The estimated metabolizable energy content of FM was about 540 kcal less than the YM. FM contained more protein (10.42 vs. 9.05%) and fibre (9.52 vs. 2.24%) compared to YM. Body weight gain, ready to cook yield, relative weights of giblet, liver, intestine and length of intestine at 42 d of age was not affected due to replacing YM with FM. But, the feed efficiency decreased in broilers fed diets containing 75 and 100% FM in place of YM at both 21 and 42 d of age. The amount of fat deposited in abdominal area decreased and the relative weight of gizzard increased with increase in level of FM in the diet. The serum HDL cholesterol at 21 and 42 d of age and serum triglycerides at 42 d of age decreased with increase in level of FM in diet. The relative weight of spleen and antibody titers against sheep red blood cells (SRBC) at 5 d post inoculation (PI) decreased in broilers fed FM at 100% of YM. However, the relative weight of bursa, SRBC titers at 10 d PI, antibody titers against ND virus and mortality were not affected due to incorporation of FM in place of YM in diet. The fat content in thigh muscle and liver decreased, while the protein content in these tissues increased with increase in the level of FM in broiler diet. Based on the results, it may be concluded that YM can be replaced with FM up to 25% on weight basis without affecting weight gain, carcass yields and immunity in commercial broiler diet (up to 42 d of age). Further, inclusion of finger millet reduced the fat deposition in thigh muscle, liver and in abdominal area compared to those fed maize as the principal source of energy.

  • As negative regulators of cytokine signaling pathways, suppressors of cytokine signaling (SOCS) proteins have been reported to possess both pro-tumor and anti-tumor functions. Our recent studies have demonstrated suppressive effects of SOCS1 on epithelial to mesenchymal signaling in colorectal cancer cells in response to fractionated ionizing radiation or oxidative stress. The objective of the present study was to determine the radiosensitizing action of SOCS1 as an anti-tumor mechanism in colorectal cancer cell model. In HCT116 cells exposed to ionizing radiation, SOCS1 over-expression shifted cell cycle arrest from G2/M to G1 and promoted radiation-induced apoptosis in a p53-dependent manner with down-regulation of cyclin B and up-regulation of p21. On the other hand, SOCS1 knock-down resulted in a reduced apoptosis with a decrease in G1 arrest. The regulatory action of SOCS1 on the radiation response was mediated by inhibition of radiation-induced Jak3/STAT3 and Erk activities, thereby blocking G1 to S transition. Radiation-induced early ROS signal was responsible for the activation of Jak3/Erk/STAT3 that led to cell survival response. Our data collectively indicate that SOCS1 can promote radiosensitivity of colorectal cancer cells by counteracting ROS-mediated survival signal, thereby blocking cell cycle progression from G1 to S. The resulting increase in G1 arrest with p53 activation then contributes to the promotion of apoptotic response upon radiation. Thus, induction of SOCS1 expression may increase therapeutic efficacy of radiation in tumors with low SOCS1 levels.

  • In recent year, We are concerned in anti-aging, disease-protection, long-life, many method are used in solving this problem. Recently, We heard that Luffae Fructus Retinervus(LFR) has effect of anti-aging, disease-protection, long-life. So I let made a experiment for this result. The purpose of this study is to; 1) the anti-oxidant effect of Luffae Fructus Retinervus(LFR) used for 3 methods, those are DPPH radical scavenging activity, Nitric oxide(NO) radical scavenging activity, Superoxide anion radical scavenging activity, 2) cultivation 3T3-L 1 Preadipocytes and Protein chip used for ProteoPlexTM 16-Well Murine Cytokine Array Kit. We measured level of DPPH radical scavenging activity. And we experienced that the ability of DPPH radical's elimination was increased by rising concentration of LFR. When the concentration of LFR was 5 mg/ml, the ability of DPPH radical's elimination was Maximum. We measured level of Nitric oxide(NO) radical scavenging activity. And we founded that the ability of NO radical's elimination was significant when concentration of LFR was from 1.25 mg/ml to 2.5 mg/ml. We measured level of Superoxide anion radical scavenging activity. And we founded that the ability of Superoxide anion radical's elimination was maximum when concentration of LFR was 0.3125 mg. When we inspected Antioxidative Effects with BSA, we experienced that ability of defense was increased by rising concentration of LFR. We known the immunity of LFR about 3T3-L1 Preadipocytes and gained the increase of Cytokines(IL-2, IL-4, GM-CSF) without IL-12p70, $INF-{\gamma}$, $TNF-{\alpha}$ So I guess that Luffae Fructus Retinervus(LFR) has effects of anti-aging, disease-protection, long-life, etc.

  • An experiment was conducted with twenty crossbred male lambs to assess the effect of cotton (Gossypium) seed meal (CSM) on blood constituents and immunity. Lambs were randomly assigned to a reference diet (30% deoiled peanut meal, DPNM) and four test diets containing 40% of either raw, 45 minutes cooked, 1% $Ca(OH)_2$ and iron (1 free gossy-pol, FG : 0.3 Fe) treated CSM (replacing approximately 50%, reference concentrate mixture). These isonitrogenous and isocaloric concentrate mixtures were fed to meet 80% of protein requirements (NRC, 1985) along with ad lib maize hay for 180 days. Blood was collected at 60, 120 and 180 days post feeding. The lambs were sensitized with Brucella abortus S99 antigen after 140 days and were subjected to ELISA and delayed type hypersensitivity. Blood haemoglobin, erythrocyte count, leucocyte count, total protein, total albumin, total globulin, urea, creatinine concentration and aspartate aminotransferase activity in lambs fed on raw or processed CSM were comparable to the values of reference lambs. The higher (p<0.01) blood glucose levels observed in CSM fed lambs at 60 days of feeding was latter reduced to the levels comparable with those on reference diet at 120 and 180 days of feeding. The alanine amino transferase activity was lower in lambs fed raw and cooked CSM containing diets at 120 and 180 days of feeding. A marginal increase in serum iron and alkaline posphatase activity was observed in iron treated group and raw CSM fed lambs, respectively. The humoral immune response and DTH reactivity was lower (p<0.05) in lambs fed raw CSM (consuming 302.83 mg FG/day). Cooking, $Ca(OH)_2$ and iron treatment of raw CSM showed a positive response in alleviating the suppression of immune response owing to the reduced consumption of FG by 40.19, 17.40% and 26.73%, respectively in these diets. The present study thus indicated that consumption of 40% raw CSM (302.83 mg FG/day) though did not affect majority of the haematological and blood biochemical parameters, but markedly suppressed the immune mechanism of lambs.

  • The recognition that omega-3 polyunsaturated fatty acids (n-3 PUFA) possess potent anti-inflammatory properties in human models has prompted studies investigating their efficacy for animal growth and immunity. This study examined the effect of feeding an n-3 PUFA-enriched diet on growth and immune response of weanling piglets. Newly weaned pigs (averaging $27{\pm}2$ days of age and $8.1{\pm}0.7kg$ of body weight) were assigned randomly to receive a control (3% vegetable oil, n = 20) or n-3 PUFA-supplemented (3% marine n-3 PUFA, n = 20) diet for 28 day after weaning. Female pigs consuming the n-3 PUFA-enriched diet were lighter at week 4 post-weaning than those fed the vegetable oil supplement. Weanling pigs gained more weight, consumed more feed and had better growth to feed ratios between days 14 and 28 than between days 0 and 14 post-weaning. Plasma insulin-like growth factor I (IGF-I) decreased between days 0 ($87.2{\pm}17.0ng/mL$) and 14 ($68.3{\pm}21.1ng/mL$) after weaning and then increased again by day 28 ($155.2{\pm}20.9ng/mL$). In piglets consuming the vegetable oil-enriched diet, plasma tumor necrosis factor alpha (TNF-${\alpha}$) increased from $37.6{\pm}14.5$ to $102.9{\pm}16.6pg/mL$ between days 0 and 14 post-weaning and remained high through day 28 ($99.0{\pm}17.2pg/mL$). The TNF-${\alpha}$ increase detected in the piglets fed vegetable oil was not observed in the piglets fed n-3 PUFA. Results indicate that weaning induces considerable immune stress in piglets and that this stress can be mitigated by dietary supplementation of n-3 PUFA.

  • Background and Objectives : Although the incidence of allergic rhinitis has increased specific therapeutics with a certain medicine is not well developed yet. In therapeutics of allergic rhinitis, limited medicines just have been used in the clinin. Sochungyong-tang has been a widespread medicine for allergic rhinitis. However, okbyeongpung-san has been taken for raising immunity. In medical treatment of allergic rhinitis, raising immunity is a necessary part of the process. In this reason, this study aimed to find out therapeutic effects of combination of sochungyoung-tang and okbyeongpung-san extract on allergic rhinintis of nasal tissue in rats. Materials and Methods : The Sprague-Dawley male rats, about 200g of body weight, were divided into three groups: the normal group, the control groups, and the sample groups. With the Levine and Vaz method, the allergic reaction was induced with ovalbumin as antigen in the intraperitoneal route. Rats of the sample groups were treated with 2cc of sochungyoung-tang plus okbyeongpung-san extract once a day for 28days. I observed historical changes in nasal tissue. I also found changes in the segment of lympocyte and neutrophil of Leukocyte and erythrocyte. I used the statistical methods of post Hoc test(p<0.05) Results : The increase of the goblet cell and mucous secretion in the sample groups was rare when compared to the control groups. Effects of sochungyoung-tang plus okbyeongpung-san extract on the liver function were also studied in rats. Treatment of sochungyoung-tang plus okbyeongpung-san extract did not affect GOT and GPT. The number of lymphocyte was decreased, while the number of erythrocyte was increased in sample groups. Conclusion : This study shows that sochungyoung-tang plus okbyeongpung-san plus okbyeongpung-san extract has considerable effects on allergic rhinitis.
