中文摘要 | 本研究在探討飼糧中添加鉻對離乳仔豬血液各型淋巴球(lymphocyte subsets)之影響。試驗採用12頭4週齡無特定病原(specific-pathogen-free)雜交離乳仔豬,逢機分配於四處理組中,基礎飼糧含有1,370 ppb鉻,各組再額外添加�p啶甲酸鉻,其鉻添加量分別為0、200、400或800 ppb,測定第7、9 及11週齡各型淋巴球比率,淋巴球種類乃利用流體細胞螢光分析儀(flow cytometer)分析各型淋巴球持有的細胞膜表面抗原(cluster of differentiation antigen)1(CD1)、CD2、CD4及CD8。試驗結果顯示,飼糧添加鉻量對不同週齡間之血液各型淋巴球比率和數目差異不顯著,但隨鉻之添加量增加具有呈直線增加第9週齡CD1�均]P<0.06)數目之趨勢,且總和第7、9及11三週之平均發現,飼糧中添加400 ppb 鉻顯著增加CD4�均]P<0.05)數目,增加至800 ppb並沒有劑量效應存在。綜合上述結果,飼糧中添加400 ppb鉻可能增加離乳仔豬之CD1�妝MCD4�妓O巴球數目。 |
英文摘要 | The effect of chromium (Cr) supplementation with chromium picolinate on the lymphocyte subsets of weanling pigs was investigated. Twelve specific-pathogen-free crossbred pigs (4 weeks old) were randomly assigned to 4 groups supplemented with 0, 200, 400, and 800 ppb of chromium. Lymphocyte subsets of cluster of differentiation antigen (CD)1, CD2, CD4, and CD8 were analyzed by the flow cytometer at age of 7,9, and 11 weeks. The data showed that the number and percentage of lymphocyte subsets were not influenced by dietary Cr levels during different week, but the number of CD1�� lymphocytes at the age of 9 weeks tended to increase linearly (P < 0.06). The overall mean number of CD4�� lymphocytes within the three weeks of study was highest for the group supplemented with 400 ppb Cr (P < 0.05). The results suggest that the supplement of 400 ppb Cr from chromium picolinate may increase the population of CD1 �� and CD4 �� lymphocyte subsets in weanling pigs. |
