Renal sexual segment, the hypertrophied region of the distal convoluted tubule and/or the forehead of the collecting duct of kidneys in the reptiles of Diapsida Lepidosauria, especially in male individual of Squamata, is a secondary structure of the male.

肾性节是一种雄性副性结构，主要存在于爬行动物双孔亚纲 Diapsida 鳞龙下纲 Lepidosauria ，尤其是有鳞目的雄性，由肾脏的集合管前端或肾单位的远曲小管末端膨大特化而成。

Results: CK18 was not detected in normal and abnormal oral tissue sections. But in normal nonkeratinized mucosa, CK19 was detected in the basal cell layer dispersively. In epithelial dysplasia, CK19 was detected in the suprabasal cell layer and the number of CK19-positive cell layers was correlated with the dysplasia degree of epithelia. Furthermore, CK19 was detected in oral squamous cell carcinoma, especially in the poor-differentiated cancer cells.

结果：正常和异常的口腔粘膜均未检测到CK18；CK19可表达于正常非角化上皮的基底层细胞、异常增生上皮的基底上层细胞及口腔鳞状细胞癌中，阳性细胞数与上皮的异常增生程度及鳞癌的分化程度相关。

The Diplodactylini + padded carphodactylines were the sister group of pygopods + padless carphodactylines. We propose a new higher order classification of the Gekkota that reflect these results.

我们据此提出了壁虎类高级阶元新分类系统的建议，把Kluge (1987)的鳞脚虎科改订为三个科，即鳞脚虎科、絮趾虎科和刺尾虎科。

In the present project,the project group investigated Cololejeunea flora of some provinces of China, collected over 500 specimens of Cololejeunea and over 7000 specimens of other liverworts,and borrowed over 3500 specimens （including 416 types）from other important herbaria. The species diversity and distribution weree clarified preliminary by means of mophologocal and ecologoical observation and studies on oil bodies and chromosomes as well as bioactivity of some species.

本项目对我国部分省区作了详尽的野外考察，采集了500余份我国疣鳞苔属的标本和7000多号其它苔类植物标本，从世界各大标本馆借阅了3500余份标本（包括416份模式标本），通过形态学，解剖学和生态学的观察，结合一些种类的染色体和油体以及生物活性的研究，初步搞清了我国和其它亚洲国家疣鳞苔属的种类和分布。

The hybrid between Brachymystax lenok and Hueho taimen were not a live in the past 2 years. However, the fertility and eyed rate of BH were significantly higher than that of HH and BB (P.05), while the hatching rate were significantly lower (P.05). The larvae died within 1 to 2 hours after hatching. It was observed that the tail of yolk-sac larve couldn't stretch around the yolk, and there were hyperemia in the middle and posterior segment of the tail. The reason why the hybrid between Brachymystax lenok and Hucho taimen couldn't snrvive might was the karyoplasms of the gametes from Brachymystax lerwk and Hucho taimen by distant hybridization were not compatible.

细鳞鲤×哲罗鱿的杂交经过2年多批次实验均未得到成活杂交子代，但在胚胎发育阶段BH的杂交受精率、发眼率均显著高于双亲自繁对照组(P.05)，但其孵化率显著低于双亲对照组(P.05)，BH杂交子代在破膜后1~2h内即死亡，刚破膜的仔鱼尾干中后段至尾鳍部分盘绕于卵黄囊表面不能伸展，且所有破膜仔鱼的尾干中后段均存在充血点，本研究认为，这种反交［细鳞鲑×哲罗鲑］子代不能成活的原因可能是由远缘杂交受精卵核质不相容所导致。
