In order to at day evaluate effect of dietary 2.0 % brown seaweed(Undaria pinnatifida) with bean extract on performance and nutrients utilization during acute phase response, one day-old broiler chicks were fed basal diet and diets substituted with 2.0 % brown seaweed and 2.0 % brown seaweed with bean extract instead of wheat bran in basal diet for 4weeks. Dietary 2.0 % brown seaweed with bean extract enhanced dietary ME value and protein accumulation due to the increased NB and decreased UAN excretion. increased feed intake during acute phase response and had the highest body weight among birds fed experimental diets. The resulted indicated that dietary 2.0 % brown seaweed with bean extract improved performance of broiler chicks due to the increased protein accumulation during acute phase response.

The effect of dietary Antartic krill(Euphausia Superba) meal on the performance of broiler chicks during the acute phase responses was studied. One d-old male broiler chicks(Avian) were fed on the experimental basal (0.0 % krill meal), and 0.5 and 1.0 % krill meal diets, and then the acute phase response were activated by injecting Salmonella typhymurium lipopolisaccharide(LPS) three times i. p. at 8, 10 and 12 day of age. The 1.0% krill meal diet group had reduced daily gain and feed efficiency during the acute phase response of the 2nd week of age, while during recovery from the acute phase response of the 3rd week of age the lowered performance disappeared. The acute phase response increased the relative weight of liver and spleen, and dietary krill meal enhanced the activities of MnSOD and Cu/ZnSOD in liver and erythrocyte cytosols during the acute phase response, although neither the acute phase response or dietary krill meal affected significantly PHA-p hypersensitivity. The results indicated that dietary krill meal affected the performance and SOD activity of broilers chicks during the acute phase response.

녹용의 알려진 약리작용 중에서 녹용의 상용량 투여에 의해 나타나는 것은 강장작용과 창상치유작용이므로 이러한 작용이 진정한 녹용의 효능으로 간주될 수 있으나 이러한 작용을 생물활성 검색법으로 활용하여 녹용의 유효성분을 검색하기에는 재현성과 간편성이라는 면에서 어려운 점이 없지 않다. 녹용의 효능이 생체의 질소평형이 음의 방향으로 진행되었을 때 이를 정상 수준으로 복귀시키는 생물활성에 기인할 것이라는 가정하에서, 실험적으로 생체내 질소편형을 음의 방향으로 전환시킬 수 있는 급성기 반응 (acute-phase responce)을 야기시킨 다음 녹용의 효과를 연구하였다. 흰쥐의 급성기 반응물질 (acute-phase reactants, APR) 중에 서 positive ARP인 ceruloplasmin, $\alpha$-cysteine pretense inhibitor(= T-kininogen)는 비색정량법으로 간편하게 측정될수 있음에 착안하여 이 단백질을 지표로 삼아 turpentine oil로 급성 염증을 유발시킨 전후에 녹용 물추출액의 효과를 측정하였다. 그 결과 녹용의 상용량에서 괴소 4일 이상 경구투여한 흰쥐에서 급성 염증유발 후 4일에서 ceruloplasmin 의 혈중농도가 현저히 감소함을 알수 있었다. 급성 염증 유발후 녹용의 경구투여한 실험에서는 적어도 녹용 상용량의 3배 이상을 투여하여야 만 ceruloplasmin 혈중 농도를 감소시킬 수 있었다. 본 연구에서 수립된 생물활성을 이용하여 녹용의 유효 성분을 단리할 계획이다.

We report the case of a 7-year-old boy who showed treatment-nonresponsive hypotension (59/29 mmHg) and decreased left ventricular systolic function (fractional shortening 22%) in the acute stage of Kawasaki disease (KD). The present case serves to highlight that methylprednisolone pulse therapy should be considered in patients with intravenous immunoglobulin nonresponsive symptomatic myocarditis during the acute stage of KD.

Two experiments were conducted to examine the effects of the acute phase response on the performance and superoxide dismutase(SOD) activities in liver and erythrocyte of broiler chicks fed dietary krill meals A and B in experiment 1 and krill meal A in experiment 2. The experimental diets are basal diet based on yellow corn and soybean meal and diets substituted 2.0% of krill meal A or B with soybean meal of the basal diet, respectively. Day-old birds fed on the experimental diets and the acute phase response(immunological stress) was activated in the birds on 8-day of age by alternate day injection i.p. with 3 doses the Salmonella typhymurium lipopolysaccharide(LPS) in saline. The values during the acute phase response were compared with those controls injected with saline. The performance; daily gain, feed intake, and feed efficiency were different between dietary krill meal A and B in birds during the acute phase response and in the control. The acute phase response increased relative liver and spleen weights. Recovery of birds from the immunological stress was different between krill meals. Dietary krill meals increased activities of MnSOD and Cu/ZnSOD in erythrocyte cytosols during the actute phase response. Dietary krill meals did not affect the PHA-p response. The results indicated that the dietary krill meals may accentuate oxidative stress during the acute phase response.

Purpose : Kawasaki disease is a systemic vasculitis, leading cause of pediatric acquired heart disease. Vascular endothelial growth factor (VEGF) has functions as vascular permeability factor, plays an important role in coronary artery lesion (CAL). We studied the clinical significance of serum VEGF in Kawasaki disease. Methods : Kawasaki group was 49 patients, and control group was 15 patients. Diagnosis followed AHA (American Heart Association) diagnostic criteria, with blood sampling in acute, subacute, and convalescent phase. Echocardiographic abnormalities were defined and the definition of intravenous gamma globulin (IVGG)-responsive and IVGG-resistant was determined. Results : Serum VEGF of Kawasaki group was significantly higher than of control group. Comparison of serum VEGF between CAL and non-CAL group, between carditis group and non-carditis group showed no significant differences. Subacute serum VEGF was statistically higher in IVGG-resistant group than in IVGG-responsive group, and serum VEGF of IVGG-resistant group in subacute phase was statistically higher than in the other phases. Serum VEGF of convalescent CAL and non-CAL group in acute and subacute phase had meaningful differences. Total fever duration and subacute serum VEGF had positive correlation. Acute serum VEGF had positive correlation with ESR and CRP, all phases serum VEGF had also positive correlation with WBC. Acute and subacute serum VEGF had negative correlations with hemoglobin and albumin. Conclusion : Serum VEGF can help to determine the severity of Kawasaki disease, especially subacute serum VEGF seems to be used as a prognostic factor of coronary complication. Afterward, further studies needed with more strict diagnostic criteria and more study groups.

In this study, the effects of dietary krill meal levels on cellular immunity in LPS-injected broiler chicks was evaluated. One day-old male broiler chicks(Ross) were fed on the experimental basal meal(0.0% krill meal), or diets containing 0.5%, 1.0% and 2.0% krill for 3 weeks, and the acute phase response was activated by intraperitoneally injection of Salmonella typhimurium lipopolysaccharide(LPS) 3 times at 9, 11, and 13 days of age. 1. Acute phase response induced a significant reduction in(p<0.05) daily weight gain and feed intake, and increases in liver and spleen weight. However, it was not affected by dietary krill meal levels. 2. The krill meal diets reduced TNF-α activity as compared to the basal diet after 24 hours (acute phase response) and 1 week(recovery from the acute phase response) following LPS injection (p<0.05). The acute phase response induced a significant increase(p<0.05) in TNF-α activity relative to the control in chicks fed on a basal diet, but this was also unaffected by dietary krill meal levels. 3. Acute phase response-mediated ovotransferrin levels(relative to what was measured in the control bird) were increased in birds fed on the basal, 1.0% and 2.0% krill diets, and were reduced in birds fed on the 0.5 % krill diet. 4. In LPS-injected chicks, 1.0% and 2.0% krill meal diets induced a significant reduction in(p<0.05) the Con A-induced proliferation of PBMC and splenocytes relative to what was observed in the chicks fed on a 0.5% krill diet, whereas the splenocytes proliferated in a linear fashion with the krill levels in the diets of the control birds. The results showed that the dietary levels of krill meal reduced TNF-α activity in the blood and also influenced blood ovotransferrin levels and the proliferation of PBMC and splenocytes, and krill meal is considered to be associated with both innate and cellular immunity in broiler chicks.

Three experiment were designed to determine the effects of dietary(n-3) fatty acids on the growth-suppressive effects of the inflammatory response and anti-oxidant enzyme activity and balances of nitrogen and energy. Day-old chicks were fed diets containing 1.0 ％ soybean oil in experiment 1, or diets containing 1.0 ％ of fish oil in experiment 2, and then on 7-d of age chicks were fed diets containing 1.0 ％ of either soybean oil or fish oil. In experiment 3, day-old chicks were fed on diets containing 1.0 ％ of either soybean oil or fish oil. In chicks of half pens within each dietary treatments of each experiments, the acute phase response were induced by injecting with Salmonella typhymurium lipopolysaccaride(LPS) i.p. 3 times at 8, 10 and 12-d of age. During acute phase response, chicks fed dietary fish oil from 1-d of age enhanced energy balances and did not give negative effect on nitrogen balance and uric acid excretion, but elevated MnSOD and Cu/ZnSOD activity In liver and erythrocyte cytosols compared with those fed dietary soybean oil. The results indicated that enhanced daily gain and metabolizable energy value of diet in birds fed fish oil from one-d of age seems due to change on the antioxidants systems during acute phase response.

Effects of interaction of dietary soybean oil with NaHCO$_3$on the energy metabolism and antioxidants enzyme activity in broiler chicks during acute phase response was studied, Broiler chicks 10 d-old were fed on diets containing 5.0 ％ of soybean oil with or without 0.5 ％(60 meq/kg) of NaHCO$_3$. Then acute phase response were induced by injecting Salmonella typhymurium lipopolysacharide(LPS) In saline 3 times i.p. at alternative day on 16-d of age. Dietary soybean oil with NaHCO$_3$lessened the performance(growth, feed efficiency, calcium balance, excretion of uric acid, and nitrogen balance) -suppressing effect of the LPS effect, but enhanced metabolizable energy value of diet due to increased digestive absorption of energy sources and phosphoruse balance, and decreased activities of SOD in erythrocyte cytosols and circulating ceruloplasmin in plasma. The results indicated dietary energy utilization and electrolytes levels may interact with the antioxidants systems during acute phase response.

To study effect of bean extracts to lessen the growth-suppressing-effect of krill meal diet, dietary krill meal with bean extracts on the performance of broiler chicks and proliferation of splenocytes and peripheral blood mononuclear cells(PBMC) and levels of circulating TNF-$\alpha$ and ovotransferrin in plasma was assayed. The krill meal with bean extracts diet lessened the growth-suppressing effect of the krill meal diet. During acute phase responce, the krill meal with bean extracts diet decreased the proliferation of splenocytes and increased the proliferation of the PBMC and reduced the circulating levels of TNF-$\alpha$ and ovotransferrin in plasma. The results Indicated that the krill meal with bean extracts diet related with the acute phase response in broiler chicks.
