Since that tumor metastasis is accompanied with proteolytic degradation of the extracellular matrix and changed cell motility, MMP-2, MMP-9 and u-PA activity were also studied via gelatin zymography and casein zymography assay to show that they all were inhibited by Terminalia catappa leaves.

在 gelatin zymography 与 casein zymography assay 中也发现到榄仁树的叶萃取物可以抑制 SCC-4 细胞中 MMP-2、MMP-9 及 u-PA 的表现。

Motilin and gastrin induced contraction of isolated gastric smooth muscle cells in a dose-dependent manner.(2) Motilin- and gastrin-induced antral smooth muscle cell contraction was inhibited by antibodies against Gαi-3. Motilin and gastrin caused an increase of Guanosine-5′-(3-［35S］thio)triphosphate(［35S］GTPγS) binding of Gαi-3.(3) Contraction of antral muscle cells induced by motilin and gastrin was inhibited by the phospholipase C inhibitor U-73122 and the IP3 receptor antagonist heparin.

结果显示：(1)胃动素和胃泌素对胃窦平滑肌细胞均有收缩作用；(2) Gαi-3抗体可抑制胃动素和胃泌素加强胃窦平滑肌细胞的收缩，胃动素、胃泌素明显增加Gαi-3抗体与［35S］GTPγS的结合；(3)磷脂酶C抑制剂U-73122、三磷酸肌醇受体拮抗剂肝素可抑制胃动素和胃泌素引起的胃窦平滑肌细胞的收缩。

During retrograde metamorphism with amphibolite facies, a little Zr released from rutile, which was transformed into titanite, can be supplied to zircon overgrowth. Therefore, SHRIMP U-Pb ages of retrograde overgrowth zircon should represent retrograde amphibolite facies age.

在退变质过程中，金红石退变为榍石的反应可释放少量Zr，因此退变质增生锆石U-Pb年龄应指示角闪岩相退变质时代。

However, Fermi resonance is an important role in the intramolecular vibrational energy transfer process, so we use the bend triatomic molecule model described by potential energy calculated from U(4) algebra, and the chaos of high excited molecular vibration can be studied by analyses of the intramolecular vibrational energy transfer process.

Fermi共振相互作用作为分子内能量转移的一种机制，在描述分子激发的完全振动方面有着重要的作用，因此，我们在构建弯曲三原子分子模型时引用了U(4)代数方法获得的势能面，从能量传递角度研究体系的混沌性质，是在多原子分子激发态领域研究非线性问题的合理延伸。

One integrative transformant was obtained through PCR and phenotype identification, designated as A.oryzae ONL1. The 7-day fermentation broth of A.oryzae ONL1 could hydrolyze tributyrin verified by forming transparent cleared zone on tributyrin plate, and the enzyme activity reached 2.5 U/mL. The SDS-PAGE electrophoretic map of the fermentation broth demonstrated that there was a typical RML band at 32.5 kDa.

其培养7天的培养液上清在以三丁酸甘油酯为底物的平板上形成清晰的水解透明圈，碱滴定法酶活测定表明培养液酶活可达2.5 U/mL，培养液上清的SDS-PAGE图谱在32.5 kDa处有RML的特征条带。

Inflorescence of paired racemes, or occasionally subdigitate, terminal and axillary, exserted or sometimes supported by a spatheole; racemes 1-sided, when paired often locked back to back and appearing as a single cylindrical raceme, spikelets of a pair similar or not; rachis internodes and pedicels stoutly linear to thickly clavate, U-shaped or triquetrous in cross section.
