摘要
采用贵妃雏鸡进行冷应激实验(比常温低5℃),通过甲苯胺蓝染色方法观察贵妃雏鸡中脾脏、胸腺中肥大细胞数目的变化。结果表明:在脾脏中,应激2h、4hMC数目显著增加,应激15d略有增加;在胸腺中,MC数目与对照组相比明显增加,应激12h差异显著,应激24h、15d差异极显著。结果提示较正常饲养温度低5℃冷应激对不同免疫器官免疫水平影响不同:应激15d后脾脏免疫水平略有提高而胸腺的免疫水平显著提高。
Royal chickens fed at relatively cold condition （lower 5℃ than normal temperature） were used to observe changes in amount of mast cells of the spleen, thymus by toluidine blue dye methods.The results showed as followed： In spleen, with 2 h, 4 h cold stress, the number of mast cells significantly increased slightly with 15 d cold stress. In thymus, amounts of mast cells increased obviously, compared with the control. Duringl2 h, change of amounts of mast cells in thymus was markedly. During cold stress 24 h, 15 d, amounts of mast cells in thymus was very markedly different from ones in the control. The result indicated that impacts of cold stress on different immune organs were different, immunity level in spleen was lightly improved, but that of the thymus were improved significantly on 15 d after cold stress.
