초록

부화 초기의 육계 병아리에게 천화분추출물을 급여한 후, LPS 처리에 의한 염증유도로 천화분추출물이 염증반응에 미치는 영향을 검토했다. 각 처리군 별 혈장 ceruloplasmin 및 ${\alpha}$-산성단백 농도의 경시적 변동경향은 전 처리군 동일하게 LPS 처리 후 증가하였다. 그러나 각 처리군 별 농도는 LPS 처리 후 3h, 9h 및 24h째 모두에서 천화분 추출물의 첨가량이 증가함에 따라 감소하는 경향을 보였다. 혈장 일산화질소 농도는 전 처리군 모두가 LPS 처리 후, 3h째에 급격하게 증가하였다. 각 처리군 별 수치는 LPS 처리 후, 3h 및 9h째 모두에서 천화분 추출물의 첨가량이 증가함에 따라 하락했다. LPS 처리 후, 간장 내의 IL-2 mRNA량은 모든 처리군들이 동일하게 2h째에 급격한 증가 현상을 보였다가, 그 후 점진적으로 하락하여 9h째에는 LPS처리 전 수준으로 회복했다. 각 처리군 별 경시적 변동 경향은 LPS 처리 후, 2h, 3h 및 4h째에서 천화분 첨가군 모두가 대조군보다 낮은 값을 보였다. LPS 처리 후, 비장 내의 IL-2 mRNA 량은 모든 처리군 들이 4h째에서 가장 높은 수치를 보였다. 처리군 별 변동 값은 천화분 0.2% 및 0.3%첨가군들이 LPS 처리 후, 3h 및 4h에서 대조군과 0.1% 천화분 첨가군들보다 높은 수치를 나타내었다. LPS 처리 후, 간장 및 비장내의 IFN-${\gamma}$ mRNA량은 모든 처리군들이 LPS 처리 후, 2h 및 3h째까지 증가하였으나, 4h에서 하락하여, 9h째에서는 LPS 처리 전 수준으로 하락했다. 그러나 각 처리군별 경시적 변동치는 최고치를 나타낸 LPS 처리 후 2h 및 3h에서, 천화분 추출물 첨가량이 증가함에 따라 하락하였다. LPS 처리 후, 간장 및 비장 내의 iNOS mRNA량은 전 처리군이 3h째에서 가장 높은 수치를 나타내었으며, 9h째에서 LPS 처리 전 수준으로 회복되었다. 처리군별 2h째, 3h째 및 4h째의 수치는 천화분 추출물 첨가군이 대조군보다 낮은 수치를 나타내었다.

Effect of Trichosanthes kirilowii extract on the inflammatory responsse was investigated in the lipopolysaccharide (LPS)-treated broiler chickens. Plasma ceruloplasmin and ${\alpha}$-acidic protein concentrations of all the experiment groups were increased at 3, 9 and 24h after LPS treatment. Plasma ceruloplasmin and ${\alpha}$-acidic protein concentrations of Trichosanthes kirilowii extract groups were lower than those of control group. Plasma nitrogen oxide concentration of all the experiment groups was rapidly increased at 3h after LPS treatment. However, plasma nitrogen oxide concentration was decreased at 3 and 9h after LPS treatment with increasing amount of Trichosanthes kirilowii extract added. Liver IL-2 mRNA concentration of all the experiment groups was rapidly increased at 2h after LPS treatment, and then gradually decreased to the level similar to that before LPS treatment at 9h after LPS treatment. Liver IL-2 mRNA concentration of Trichosanthes kirilowii extract groups were lower than that of control group. Spleen IL-2 mRNA concentration was the highest at 4h after LPS treatment in all the experiment groups. Spleen IL-2 mRNA concentration of 0.2 and 0.3% Trichosanthes kirilowii extract groups were higher than that of 0.1% Trichosanthes kirilowii extract group and control group at 3 and 4h after LPS treatment. Liver and spleen IFN-${\gamma}$ mRNA concentrations were increased at 2 and 3h after LPS treatment, decreased at 4h after LPS treatment, and then reached to the level similar to that before LPS treatment at 9h after LPS treatment. Liver and spleen IFN-${\gamma}$ mRNA concentrations of Trichosanthes kirilowii extract group were lower than those of control group at 2h and 3h after LPS treatment. Liver and spleen iNOS mRNA concentrations were the highest at 3h after LPS treatment, and then decreased to the level similar to that before LPS treatment at 9h after LPS treatment. Liver and spleen iNOS mRNA concentrations of Trichosanthes kirilowii extract groups were lower than those of control group at 2, 3 and 4h after LPS treatment.
