2.1 DON和APTF对鸡胚腺胃脏器指数的影响
图1 DON和APTF对鸡胚腺胃脏器指数的影响数据柱形标注不同字母表示差异显著(P<0.05),相同字母表示差异不显著(P>0.05)。图3至图5同。 Fig.1 Effects of DON and APTF on organ index of glandular stomach in chicken embryos Data columns with different letters indicated significant difference (P<0.05), while with the same letter indicated no significant difference (P>0.05). The same as Fig.3 to Fig.5. |
2.2 DON和APTF对鸡胚腺胃组织病理结构的影响
图2 DON和APTF对鸡胚腺胃组织病理结构的影响腺胃组织苏木精-伊红染色图。绿框:腺小叶上皮细胞排列紊乱,部分区域出现上皮空泡化和脱落;黄框:间质可见大量淋巴细胞和粒细胞浸润;红色箭头:黏膜上皮细胞空泡化严重;蓝色箭头:局部血管扩张明显。 Fig.2 Effects of DON and APTF on histopathological structure of glandular stomach in chicken embryos (40×) Hematoxylin-eosin staining images of glandular stomach tissues. Green box: disorganized arrangement of glandular lobule epithelial cells, with vacuolization and exfoliation in some areas; yellow box: interstitial infiltration of numerous lymphocytes and granulocytes was observed; red arrow: severe vacuolization of mucosal epithelial cells; blue arrow: marked local vascular dilation. |
