中文摘要 | 本研究以添加不同濃度的維生素E (all-rac-α-tocopherol) (0、50、500和5000 mg/kg) 的四種飼料分別餵飼平均體重10.2 ± 0.3 g 的點帶石斑 (Epinephelus coioides) 稚魚,以探討飼料中維生素E的含量對石斑稚魚頭腎白血球的吞噬、呼吸猝發 (respiratory burst) 和白血球增生等活性之影響。結果顯示,攝取添加維生素E飼料的各組試驗魚,其成長和頭腎白血球的吞噬和增生活性等均顯著優於未添加維生素E者,但活存率則不受飼料維生素E影響。餵飼添加維生素E 500 mg/kg DW (dry weight) 飼料的試驗魚,其白血球的吞噬活性顯著高於其他試驗組者 (p < 0.05),然頭腎白血球的呼吸猝發活性則不受維生素E影響。當以Con-A、PHA-P或LPS誘導白血球,攝取含高量維生素E飼料 (500或5000 mg/kg DW) 的試驗魚之增生活性顯著高於攝取不添加維生素E試驗組者。因此,攝取500 mg/kg DW維生素E可有效地促進石斑魚的白血球之吞噬和增生活性,但不會影響呼吸猝發活性。 |
英文摘要 | Juvenile orange-spotted grouper (Epinephelus coioides) were fed experimental diets with four levels of vitamin E (all-rac-α-tocopherol) (0, 50, 500, and 5000 mg/kg diet) for 12 wk to investigate the effects of feeding these vitamin E-enriched diets on phagocytic, respiratory burst, and leukocyte proliferative activities. Fish fed the diet without vitamin E showed reduced growth, head-kidney leucocyte phagocytic activity, and proliferation, but no difference was detected in survival. When fish were fed 500 mg/kg dry weight (DW) vitamin E, enhanced phagocytic activity was found, which was significantly higher (p < 0.05) than those of fish fed the other diets. There were no effects of dietary vitamin E intake on respiratory burst activities of head-kidney leucocytes. Leucocyte proliferation was significantly higher in fish fed the diet with higher vitamin E levels (500 and 5000 mg/kg) than those fed the diet without vitamin E, when stimulated by Con-A, PHA-P, and LPS. Data showed that vitamin E (500 mg/kg DW) could efficiently stimulate grouper leucocyte phagocytic and proliferative activities, but not respiratory bursts. |
