图 3：正常<br>十二指肠远端黏膜 X 100（冷冻切片）中的维生素 D 受体染色。染色<br>在隐窝中最大，沿绒毛减少。箭头<br>标记隐窝颈部，从该隐窝颈部<br>向上获取到绒毛尖端（箭头）<br>和向下到绒毛基部（箭头）的核吸光度读数。见图 2。

Figure 3: Vitamin D receptor staining in normal distalduodenal mucosa X 100 (frozen section). Staining ismaximal in the crypts, diminishing along the villus. Arrowsmark the crypt neck from which nuclear absorbancereadings are taken upwards to the villous tip (arrow),and downwards to the villous base (arrow). See Figure 2.<br>

图3:正常远端的维生素D受体染色十二指肠粘膜X 100(冰冻切片)。染色是在隐窝中最大，沿绒毛递减。箭头标记隐窝颈部，从那里核吸收读数被向上带到绒毛顶端(箭头)，向下到达绒毛基部(箭头)。参见图2。
