본 연구는 구멍갈파래 급여가 육계 혈액 내 항산화, 면역조절 효과에 미치는 영향을 구명하기 위해 실시 하였으며, 이를 위해 LPS로 염증반응이 유도된 육계에서 혈액 SOD 유사 활성, immunoglobulin 농도 및 비장 조직 내 cytokine mRNA 발현을 조사하였다. 공시계로는 1일령 Ross종 육계수컷 96수를 선별하여, 육계전기(0~3주), 육계후기(3~5주)의 5주 동안 사양시험을 실시하였다. 처리당 24수(3수${\times}$8반복)씩 4처리구에 총 96수를 임의배치 하여 실시하였다. 시험구 배치는 무첨가구(Negative Control ; NC), 시판 면역증강제 첨가구(Positive Control ; PC, ${\beta}$-glucan 25 ppm), 구멍갈파래 분말 3% 첨가구(Ulva pertusa kjellman Powder ; Ulva P) 및 구멍갈파래 추출물 0.3% 첨가구(Ulva pertusa kjellman Extract ; Ulva E)로 배치하였다. 혈액 내 SOD 유사 활성을 분석한 결과 구멍갈파래 첨가구 (Ulva P, Ulva E)는 무첨가구와 면역제제 첨가구보다 높은 항산화 활성을 가지는 것으로 나타났다(P<0.05). immunoglobulin 농도에서 IgA와 IgG 농도는 처리구간의 차이가 나타나지 않았지만 IgM농도에서 구멍갈파래 추출물 처리구가 무첨가구에 비해 유의적으로 낮은 수준을 나타냈다(P<0.05). 이는 구멍갈파래 추출물이 LPS에 대한 면역자극을 조절하여 과잉면역반응을 억제한 것으로 사료된다. 비장 조직 내 cytokine mRNA 발현량을 조사한 결과 IL-1, IL-2 및 IL-6에서 처리구별 공통적인 차이를 나타내었는데 구멍갈파래 처리구(Ulva P, Ulva E)의 mRNA 발현 비율이 무첨가구와 면역제제 처리구에 비해 낮았으며, 구멍갈파래 처리 간 비교에서 구멍갈파래 추출물이 분말보다 더 낮았다(P<0.05). iNOS의 경우 구멍갈파래 분말 첨가구는 무첨가구와 유의적인 차이가 없었지만 구멍갈파래 추출물 첨가구는 모든 처리구보다 iNOS의 발현이 낮았다(P<0.05). 구멍갈파래 분말과 추출물은 LPS 주입에 의한 염증 관련 사이토카인 mRNA 발현을 억제하는 경향을 나타내며, 특히 구멍갈파래 추출물이 발현억제 효과가 더 높은 것으로 확인되었다(P<0.05). 본 연구 결과 육계에서 구멍갈파래 급여는 염증, 질병의 원인인 활성산소 제거에 효과가 있다고 사료된다. 특히 구멍갈파래 추출물은 혈액 내 IgM의 농도를 조절하여 외부항원에 대한 과잉면역반응을 억제하고 염증 관련 cytokine mRNA 발현을 억제하여 육계 면역조절에 긍적적인 영향을 미치는 것으로 사료된다.

목 적 : 마이코플라스마 폐렴은 일부 천식의 과거력이 없는 환자에서도 천명, 호흡곤란 등의 증상을 보여 천식의 발생과 관계된다고 한다. VEGF는 천식의 만성 염증 형성에 중요한 역할을 한다. 본 연구는 마이코플라스마 폐렴에서 천명이 동반되는 환아와 천명이 없는 환아에서 혈청 VEGF의 농도가 차이가 있는지 알아보고자 하였다. 방 법 : 2006년 8월부터 2007년 2월까지 고려대학교 안암병원 소아과에 천식의 과거력이 없는 마이코플라스마 폐렴으로 입원한 환아들 중 의사의 청진상 천명음이 처음으로 확인된 환아 9명(천명군)과 천명음이 한번도 없었던 비천명군 63명을 대상으로 혈청 VEGF농도, M. pneumoniae 항체가, 혈액 호산구 염증지표 및 혈청 IgE 농도 등을 측정하였다. 결 과 : 천명군의 혈청 VEGF 농도는 $650.2{\pm}417.9pg/mL$로 비천명군($376.5{\pm}356.2pg/mL$) 보다 높게 나타났고(P=0.049), M. pneumoniae 항체가도 천명군에서 더 높았다(1:1,380 vs. 1:596, P=0.048). 혈청 총IgE 값은 천명군이 591.8 IU/mL, 비천명군이 162.2 IU/mL 이었다(P=0.032). 두 군의 말초혈액 호산구수(천명군 : $263.0/{\mu}L$ vs. 비천명군 : $166.5/{\mu}L$)와 혈청 ECP 농도(천명군 : $22.8{\mu}g/L$ vs. 비천명군 : $17.4{\mu}g/L$)는 유의한 차이가 없었다. 천명군에서 혈청 VEGF 농도는 항체가와 유의한 상관관계를 보였다(r=0.568, P=0.034). 결 론 : 천식의 과거력이 없는 아토피 소아에서 높은 VEGF 농도는 마이코플라스마 폐렴에서 천명 발생과 관계가 있는 것으로 생각할 수 있으며, 이들 환자에서 앞으로 천식 발생 유무에 대한 추적 관찰이 필요하리라 생각한다.

The general pharmacological properties of YJA20379-1 2-dimethylamino-4,5-dihydrothiazolo[4,5:3,4]pyridol[1,2-a]benzoimidazole, a novel proton pump inhibitor with antiulcer activities were investigated in mice, rats, guinea pigs and rabbits. YJA20379-2 at oral doses of 50, 100 and 200 mg/kg did not affect the general behaviour, hexobarbital hypnosis and motor coordination in mice. The drug did not have analgesic or anticonvulsant action at 200 mg/kg. Locomotor activity and body temperature were not influenced at 100 mg/kg. At a concentration up to 2{\times}10^{-4} g/ml$, YJA20379-2 did not produce any contraction or relaxation of isolated preparations, such as the rat fundus, the guinea pig ileum and the rat uterus, and did not antagonize the contractile response to several spasmogens, such as histamine, acetylcholine, serotonin and oxytocin. At dosages up to 200 mg/kg p.o. YJA20379-2 did not affect the pupil size of mice. Intestinal propulsion of mice was not affected up to 200 mg/kg p.o. and the drug did not affect urinary excretion at 100 mg/kg p.o. These results indicate that at dosages up to 100 gm/kg p.o. YJA20379-2 was found not to affect this pharmacological profile. However, at 200 mg/kg the drug lowered body temperature and showed decreased in locomotor activity and urine volume.

This study was designed to investigate the antibody production to sheep red blood cells(SRBC) and proliferation of mitogen-stimulated spleen cells in Balb/c mice which received cadmium chloride. The mice were divided into three independent groups which were one control and two experimental groups by the cadmium treatment or not. No specific treatment was done for the control group. One of two experimental groups, which is called 'pre-treatment group' in this paper, was subcutaneously injected with low dose of cadmium chloride(0.5 mg/kg/day) for 5 consecutive days before the primary SRBC immunization. The other called 'non-pretreatment group' was only pretreated with normal saline. Both experimental groups were intraperitoneally injected with high dose of cadmium chloride(5 mg/kg) 8 hours before the primary immunization. Mice were intraperitoneally immunized twice with 2% SRBC suspension containing $10^8$ cells. The results obtained were as follows, 1. The PFG responses to SRBC were significantly increased in two experimental groups, cadmium pretreatment and non-pretreatment compared with that of control group(p<0.05). 2. The total antibody titers to SRBC in cadmium treated groups were similar to that of control group, but titers of IgG antibody were significantly elevated(p<0.01). 3. The proliferation response of spleen lymphocytes to various mitogens was suppressed in proportion to the concentration of cadmium and the degree of cadmium accumulation in liver was increased in the cadmium treated groups. These results suggest that cadmium chloride could affect on mouse immune response, especially its cell mediated immune response could be decreased while its humoral immune response could be increased, which may not be influenced by the administration methods or pretreatment of cadmium to mouse.

Objective : The main purpose of this study was to evaluate the effect of Jasinwhalhyul-tang (Zishenhuoxue-tang, JWT) on MRL/MpJ-Ipr/Ipr mouse model with systemic lupus erythematosus. Methods: The effect of JWT on MRL/MpJ-Ipr/Ipr mice that have autoimmune disease similar to SLE in humans was evaluated after JWT per oral in the present study. Mice were administered with Jasinwhalhyul-tang (Zishenhuoxue-tang, JWT) (80 or 400mg/kg) or distilled water for control group from experimental week 10 for 22 weeks. Results : The amount of erythematosus skin lesion and proteinuria were significantly decreased. The size and weight of cervical lymph nodes and spleen were significantly reduced. The ratio between activated $CD3^+CD69^+$ T-cells and undifferentiated $CD3^+CD4^-CD8^-$ T-cells in lymph nodes, spleen and kidney was effectively reduced. The gene expression of TGF-$\beta$ in spleen and kidney was increased. The amount of anti-dsDNA IgG in blood was decreased. The gene expression of TGF-$\beta$ in normal mouse spleen cells was increased depending on concentration by treatment of with T cell stimulating agent. In the histological examination of skin and kidney, the amount of infiltration of immune cells involved in the inflammatory response was decreased. Conclusions : According to the above results, JWT should be considered as an applicable therapeutic agent to SLE in clinical practice. Further research is required to investigate other efficacies of JWT on SLE.

Two experiments were conducted to investigate the effects of supplemental glutamine on growth performance, plasma parameters and LPS-induced immune response of weaned barrows after castration. In experiment 1, forty-eight weaned male piglets were used and fed maize and soybean meal diets supplemented with 0 (Control) or 2% L-Gln (Gln+) for 25 days. The results indicated that the Gln+ group tended to increase average daily gain compared to control in stages of days 7 to 14 and 0 to 25. The Gln+ had significantly better feed efficiency than the control group did during days 14 to 25 and 0 to 25. The plasma blood urea nitrogen and alkaline phosphatase contents of Gln+ group were higher than those of the control group on day 14 post-weaning. In experiment 2, sixteen weaned male piglets were injected with E. coli K88+ lipopolysaccharide (LPS) on day 14 post-weaning. The results showed that the Gln+ group had lower concentrations of plasma adrenocorticotrophic hormone and cortisol than the control group on day 14 pre-LPS challenge. In addition, Gln+ group had higher plasma IgG concentration than the control group for pre- or post-LPS challenged on day 14 post-weaning. In summary, dietary supplementation of Gln was able to alleviate the stressful condition and inflammation associated with castration in weaned barrows, and to improve their immunity and growth performance in the early starter stage.

Critical parameters affecting sensitivity and specificity of an enzyme-linked immunosorbent assay(ELISA) for detection of antibodies to avian infections bronchitis virus(IBV) were standardized. By adopting the optimized conditions an equation calculating ELISA antibody titers from the observations at single serum dilution was formulated. The purified antigen of IBV Mass-41 strain was dispensed into polystyrene microplate wells at a concentration of 300ng per well($100{\mu}l$) and the plates were coated by completey drying at $37^{\circ}C$. Diluted chicken serum and horseradish peroxidase conjugated goat anti-chicken IgG were added in order in $100{\mu}l$ volumes per well and allowed to react for 30 minutes each at room temperature. Just before use and after each reaction the plates were washed three times with distilled water. Finally o-phenylenediamine solution was added as an enzyme substrate. After incubation for another 15 minutes at room temperature absorbances were read at 492nm. Hyperimmune serum against Mass-41 strain was used as internal reference positive(IRP) serum. After repeated titration of IRP and negative serum, a constant titer of IRP was determined. Serum titrations were carried out for various sample sera together with IRP and negative sera and the observed titers of sample sera were corrected by reflecting the ratio between observed and constant titers of IRP serum. These corrected titers of the sample sera were plotted against sample/positive(S/P) OD ratios. All the OD's measured in the serum titrations were also corrected by substracting negative serum OD. The following equation was formulated from the above data; $Log_{10}$ ELISA titer=$5.568({\log}_{10}S/P)+4.161$ Thus it was possible to calculate ELISA titer by measuring absorbance at 1/400 single serum dilution. Titer measured by cross ELISA tests employing Mass-41 strain and three local IBV isolates were similar. These results suggest that the ELISA tests standardized in this study can be used for evaluating not only vaccinal immunity but also for infection status against fields IBV's.

This study was designed to evaluate the influence of dietary supplementation of Tenebrio molitor larvae (TM) as an alternative source of protein to fish meal on growth response, retention of nutrient, hematological factors, immune system, and intestinal integrity in weaned pigs. A total of 180 weanling pigs (initial bodyweight of 6.27 ± 0.15 kg; 21 d) were distributed based on the bodyweight between 3 treatments with 6 replicates in each treatment including 10 piglets per replicate. The diets corresponding to treatments consisted of a fish meal diet (CON), a fish meal-dried mealworm diet (TM1, 50% replacement of fish meal with TM meal), and a dried mealworm diet (TM2, 100% replacement of fish meal with TM meal). This study was performed in two phases as phase 1 (d 0 to 14) and phase 2 (d 15 to 28). The pigs in the TM2 treatment showed a greater gain to feed ratio compared with the TM1 pigs in phase 1. Throughout the experimental period, the average daily gain (ADG) of the TM1 pigs was significantly greater than that of the TM2 treatment. The IgG concentration was increased in the TM1 and TM2 treatments compared with the CON pigs in phase 1. In conclusion, the supplementation of TM meal (50% replacement of fish meal) did not show any adverse effects in the performance of weanling pigs, however, 100% replacement of fish meal with TM meal is not recommended.

This study was conducted to evaluate the effect of honeybee venom, purified using bee venom collector, and feeding of probiotics on the body weight gain, growth rate and hematological characteristics of pigs. A total of 120 pigs were examined and divided into 4 groups 1) Control (basal diet), 2) BV (basal diet + bee venom), 3) PB (basal diet + probiotics), 4) BVPB (basal diet + BV + PB). Average daily weight gain improved significantly in all test groups, especially BVPB (P < 0.05) compared to the controls. There was a significant difference in the feed conversion rate (P < 0.05) and efficiency (P < 0.05) between BVPB and control pigs. Weight gain and survivability was higher in the tests than the controls, but white blood cell count was not. Serum total protein, albumin and IgG concentration of BVPB were slightly higher than those of controls. These results suggest that treated honeybee venom and probiotics should be used together to effectively increase the productivity of pigs.
