蜂猴(Nycticebus coucang)和树鼩(Tupaia belangeri chinensis)mt DNA 10种限制酶物理图谱

本研究用10种限制性内切酶对蜂猴和树鼩肝脏线粒体DNA进行了分析. 蜂猴线粒体DNA, BglⅠHind Ⅲ、PstⅠ、SalⅠ和XhoⅠ均各只1个切点、EcoRⅠ、BglⅡ和Pvu Ⅱ各有2切点, BamHⅠ和 EcoRⅤ 分别有3个切点. 对于树鼩线粒体 DNA, BglⅡ、Hind Ⅲ、PstⅠ、SalⅠ和 XhoⅠ均只1个切点, BamHⅠBglⅠ和 PvuⅡ 分别有2个切点, EcoRⅠ 有3个切点, EcoRⅤ有4个切点. 根据单酶和双酶解片段的数目和分子量, 建立了蜂猴和树鼩线粒体 DNA 的物理图谱。

Anti-HIV-1 activities of extracts from the medicinal plant Rhus chinensis

Rhus chinensis, a species used in folk medicine by Chinese native people, the anti-HIV-1 activities of the petroleum ether, ethyl acetate, butanol and aqueous extract of Rhus chinensis, named as RC-1, RC-2, RC-3 and RC-4, respectively, was evaluated. The

Anti-HIV-1 activities of compounds isolated from the medicinal plant Rhus chinensis

Aim of the study: Previously, we reported that the petroleum ether fraction, RC-1, and EtOAc fraction, RC-2, of the medicinal plant Rhus chinensis showed potent anti-HIV-1 activities. To address anti-HIV-1 constituents of RC-1 and RC-2, 17 compounds were

Isolation and characterization of miscellaneous terpenoids of Schisandra chinensis

Two new bisnortriterpenoids with 18-norschiartane skeleton, wuweizidilactones G (1) and H (2), four new highly oxygenated nortriterpenoids based on a schisanartane skeleton, schindilactones D-G (3-6), a pre-schisanartane skeleton, pre-schisanartanin B (7)

树鼩(Tupaia belangeri chinensis)花斑病的研究

树鼩作为一种实验动物已在许多实验室驯养繁殖. 在进入家养条件下, 由于环境的改变可能导致一系列生理功能和病理变化. 在作者实验室饲养的树鼩中, 有部分树鼩出现块状脱毛现象. 作者进行了临床检查. 血液氨基酸, 矿物质和睾酮含量的测定。

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
