【摘要】 本实验采用 70 只伊褐红公雏鸡进行急性及慢性冷应激实验(比常温低 8 ℃),通过甲苯胺蓝染色法光镜下观察腺胃中肥大细胞数目的变化。结果表明:急性冷应激 2h 时,雏鸡腺胃肌层中肥大细胞数目明显增加(p<0.01);慢性冷应激 3d 时,雏鸡腺胃肌层中肥大细胞数目减少(p<0.05);慢性冷应激 10d 时,腺胃肌层中肥大细胞数目明显增加(p<0.01)。本实验结果提示在冷应激过程中肥大细胞可能通过其炎性介质的释放对胃道粘膜充血有一定影响。更多还原

【Abstract】 In the experiment,70 male yihehong chickens were used to observe the effects of cold stress (lower 8 ℃ than the control) on amount of mast cells in glandular stomach by histochemistry and improved toluidine dye methods. The results showed as follow: Compared with the control group, the numbers of mast cells in muscle layer of glandular stomach was increased significantly (p<0.01) after 2 hours cold stress, and lowered in 3 days post-cold stress (p<0.05), increased markedly in 10 days post-cold stress (p<0.01). The results indicate that mast cells might affect gastric hyperemia by releasing of mediators in cells in the course of cold stress.更多还原
