树qu(Tupaia belangeri chinensis)的脊神经丛

树qu脊神经丛的研究结果: 颈丛恒定由C_(2-4)组成, 但各条神经的组成不十分恒定; 没有真正的舌下袢, 支配肩胛舌骨肌、胸骨舌骨肌和胸骨甲状肌的神经仅来自C_(10); C_(4)和C_(5)为膈神经的恒定成分, 其变化范围为C_(3-7); 臂丛由C_(5)-T_(2)组成, 结合为三干三索; 肩胛上神经在组成上有变化, 可由C_(5,6)或C_(5-7)组成; 腰骶丛由L_(1)-S_(2)或L_(2)-S_(2)组成;腰骶丛各条神经的组成有一定的变化, 似乎没有一条神经在其神经根组成上是恒定不变的。图5参21

树鼩(Tupaia belangeri chinensis)消化系统解剖和组织学观察

该文对云南产中国树鼩的消化系统作了大体解剖和组织学观察, 在此基础上描述了树鼩消化系统的主要特征, 并与其他有关种类作了比较和讨论。

树qu(Tupaia belangeri Chinensis)的动脉

中国树qu动脉系的主要特征与树qu科中的其他种类如笔尾树qu、普通树qu和 地树qu等的动脉系极为相似,而与灵长类中的猿猴类有较大差异。图4参14

树Qu(Tupaia belangeri Chinensis)卵巢的显微结构及不同季节的卵巢活动

树Qu卵巢的间质腺组织稀少,但普遍有“睾丸索”型的髓质索结构。卵泡发育过程类似于大多数哺乳类和灵长类。孕期黄体和副黄体结构见于7月份 ,10月份未见孕期卵巢结构,多数卵巢缺乏生长活性的大囊状卵泡的发育,表明树Qu的卵巢活动同睾丸的精子发生一样,有季节性变化。图版1表3参14

中华双腔吸虫（Dicrocoelium Chinensis Tang et Tang，1978）（Trematoda：Digenea）卵子发生的超微结构研究

利用透射电镜技术观察了中华双腔吸虫（ＤｉｃｒｏｃｏｅｌｉｕｍｃｈｉｎｅｎｓｉｓＴａｎｇｅｔＴａｎｇ，１９７８）的卵巢结构和卵子发生过程，同时提出了划分复殖吸虫卵子发生过程的标准，总结了复殖吸虫卵子发生的一般规律以及中华双腔吸虫卵子发生的特有特征。此外比较分析了不同复殖吸虫的皮质颗粒特征，指出它在分类上可能有重要意义。中华双腔吸虫卵巢和卵子发生的超微结构与大多数复殖吸虫相似，但其卵巢中的各生殖细胞间有网状片层结构及一些颗粒、膜状碎片等支持和营养结构，还有退化的成熟卵母细胞。中华双腔吸虫的卵子发生分为卵原细胞

Indole Alkaloids from the Leaves of Anthocephalus chinensis

Anthocephalusine A (1) and 3 beta-isodihydrocadambine 4-oxide (2) were isolated from the leaves of Anthocephalus chinensis (Rubiaceac), together with five known compounds. The structures were established by spectroscopic methods including 2D-NMR analyses.

Studies on lignan constituents from Schisandra chinensis (Turcz.) Baill. fruits using high-performance liquid chromatography/electrospray ionization multiple-stage tandem mass spectrometry

A reversed-phase high-performance liquid chromatography-diode array detector-electrospray ionization multiple-stage tandem mass spectrometry (RP-HPLC-DAD-ESl-MSn) method has been developed for the detection and analysis of lignan constituents in the methanol extract from the fruits of Schisandra chinensis (Turcz.) Baill. RP-HPLC-DAD-ESI-MSn and electrospray ionization Fourier transform ion cyclotron resonance multiple-stage tandem mass spectrometry (ESI-FT-TCR-MSn) have been applied to investigate the characteristic product ions of four lignan reference compounds. Then, the logical fragmentation pathways of the lignans have been proposed. By comparing the retention time (t(R)) of HPLC, the ESI-MSn data and the structures of analyzed compounds with the data of reference compounds and in the literature, 11 peaks in HPLC have been unambiguously identified and another 5 peaks have been tentatively identified or deduced. Also, in the present paper, the extracted ion chromatograms (EIC) have been used to analyze the lignan isomers. The experimental results demonstrate that RP-HPLC-DAD-ESI-MSn is a specific and useful method for the identification of the lignan constituents and their isomers.

Foreign gene transfer into Chinese shrimps (Penaeus chinensis) with gene gun

Plasmids pG DNA-RZ1 with a GFP (green fluorescent protein) reporter gene and a ribozyme gene incising penaeid white spot baculovirus (WSBV) were first introduced into the fertilized eggs of Chinese shrimps by gene gun. The treated and control samples of different development stages were observed with a fluorescent microscope. The transient expression of GFP gene was high in nauplius and zoea larvae. Results from RT-PCR and PCR for adults showed that the foreign genes had been transferred into the shrimps and had expressed the corresponding proteins. This work has established a transgenic method for penaeid shrimps, which will set base for the application of genetic engineering breeding into industry.
