We analyzed the polymorphism of MHC class II B gene in 14 Chinese alligators sampled from three different areas: the wild population of Xuancheng in Anhui, the captive population of Changxing in Zhejiang and the captive population of Anhui Research Center for Chinese Alligator Reproduction. The gene fragment was amplified using a pair of specific primers designed from the MHC gene sequence of the Spectacled caiman. A total of thirty-four different sequence (15, 10 and 9, respectively) were detected in sampled Chinese alligators.

为了研究扬子鳄种群MHC基因的多态性，我们选取了安徽宣城野生扬子鳄种群、安徽省扬子鳄繁殖研究中心饲养种群和浙江长兴饲养种群三个亚种群的14条扬子鳄，利用一对特异性引物扩增出扬子鳄MHC II类B基因第三外显子的部分片段，并对其进行了克隆、测序，结果从这些扬子鳄样本中共获得34种不同序列，每个亚种群内分别检测到15，9和10个不同序列。

On the other hand, poetry is also advantageous to nature; it is the eulogy of poetry that achieves the fame for the places of interest; it is the poetry that beautify the natural surroundings, which will consequently enhance the original value; it is the wisdom in poetry that spiritualize human mind, therefore, nature will be correspondingly preserved and protected.

另一方面，诗歌也对自然产生了多方面的助益：借助诗歌的传颂，许多自然风景得以流芳千古；借助诗歌的力量，自然物也平添了更多的人文色彩，提升了原有的价值；借助诗歌的智慧，人类的心灵获得了净化，自然则得到了更多人的尊重与保护。
