Histological structures of bursas of Fabricius were observed at the different developmental stages from chicken embryoes to chickens. The results were as follows. The bursa of Fabricius began to develop on the 13th day of post-hatching and its cell aggregated into the nodosity clique underneath the epithelium mucosae. On the 15th day of post-hatching, those cell cliques were surrounded by the flat epithelium and formed the basic structure of folliculus lymphaticus. The number of lymphocytes in the folliculus lymphaticus increased gradually, and the medulla and cortex of a majority of folliculus were not discriminated obviously. Until on the 7th day for chickens, the medulla and cortex of folliculus formed completely and the number of folliculus increased significantly. From 21 to 35 days old, the folliculus lymphaticus transformed from polygon into rectangle. Mucosa epithelial cells increased gradually and their cytoblasts arranged compactly into aline in the basilar part on the 35th day.

本研究观察了从鸡胚到出壳后的不同生长发育阶段法氏囊的组织结构，结果表明：胚胎13日龄时，法氏囊开始发育，粘膜上皮下形成结节状细胞集团；胚胎15日龄，聚集的细胞集团形成初始的淋巴滤泡；胚胎18日龄到出壳后1日龄，滤泡内淋巴细胞数量增多，多数滤泡髓质和皮质界限仍不明显；7日龄雏鸡法氏囊髓质皮质分界清晰，滤泡数量显著增多；21日龄到35日龄，滤泡由多边形逐渐转变成长方形；在35日龄时，粘膜上皮细胞逐渐增多，排列紧密，细胞核紧密排列成直线位于基底部。

Modern astronomers has proved to be the ancient Maya predicted in 2012 on 21 December, the Earth, the Sun and the Galactic Centre will precisely in a straight line, the astronomical events only every other year 25800 occurs only once, no one knows this unusual arrangement on earth can, but the Mayan people know this is terrible.

现代天文学家已证实古玛雅人所预言的在2012年12月21日，地球，太阳和银河中心将精确地排列成一条直线，这个天文现象只有每隔25800年才会发生一次，没人知道这种非同寻常的排列方式对地球会有怎样的影响，但玛雅人知道这是可怕的。
