图4. H.hepaticus感染小鼠16周后结肠组织HE染色(A)、阿尔辛蓝-过碘酸希夫染色(B)和Masson染色(C)
注:VDR-/-小鼠感染组表现为更为严重的淋巴细胞浸润,杯状细胞缺失和黏液分泌减少,并且胶原纤维沉积变多。其中放大倍数×40的比例尺为500 μm,×200的比例尺为100 μm,×100的比例尺为200 μm。

Note: The VDR-/-+H.h group exhibited more severe lymphocyte infiltration, loss of goblet cells, and reduced mucus secretion, along with increased collagen fiber deposition. The magnification is ×40 with a scale bar of 500 μm, ×200 with a scale bar of 100 μm, or ×100 with a scale bar of 200 μm.
