Objective To analyse the vasodilative mechanism of isocorydine, its effects on the increasing of the cytosolic free Ca 2+ level ([Ca 2+ ]i) induced by noradrenaline and high potassium in the blood vessel smooth muscle cells were investigated.

目的 观察扩血管药异紫堇啡碱对去甲肾上腺素和高钾所致血管平滑肌细胞内游离钙浓度([Ca2 + ]i)增高的影响，分析该药扩血管作用的原理。

Objective To analyse the antiarrhythmic mechanism of isocorydine,its effects on the increasing of the cytosolic free Ca 2+ level ([Ca 2+ ] i) induced by noradrenaline and high potassium in the cultural newborn rat beart cells were investigated.

目的 观察异紫堇啡碱对去甲肾上腺素和高钾所致培养乳鼠心肌细胞内游离钙浓度([Ca2 + ]i)增高的影响，初步分析该药心脏效应的作用原理。

Interestingly, in ventricular myocytes, there was a significant expression of the Ca〓-independent isotype PKC-ε in 4 and 20 weeks SHR compared with WKY, while Ca〓-dependent isotype PKC-r could not show expression.

结果显示：1。在幼、成年SHR大鼠脑皮质组织中，PKC-r亚型基因表达均较同龄对照鼠显著升高，而PKC-ε亚型基因表达在二组无显著差异。2。

Studies of the binding of metal to calmodulin and the subsequent binding of metal-calmodulin complexes to the target protein/peptide revealed that the La-content calmodulin complexes to its target exhibit similar affinity with the Ca-calmodulin complexes.However, there were substle differences in protein conformation as well as the kinetical properties between the two kinds of metal-calmodulin complexes, suggesting Ln could produce cellular effects via the Ca/calmodulin signaling systems.

稀土离子和钙调蛋白的结合以及后续和靶酶的结合，在热力学上与钙离子激活蛋白具有相同的亲合力，但在动力学性质上以及细微构象上明显不同，显示稀土离子可通过细胞钙相关信号系统产生特别的生物效应。

The mice with alloxan-induced diabetes mellitus were orally administrated with the crude extracts and the crystal phloridzin from Lithocarpus polystachyus Rehd, and their fasting blood level as well as no-fasting level were reduced significantly, and their glucose tolerance curves also were improved.

降血糖机制研究结果表明，CA和PHL对正常和糖尿病小鼠的降血糖机制与阿卡波糖不同；CA和PHL有效降低了血清MDA水平，提高了血清SOD和GSH-Px活性，说明糖尿病小鼠体内的抗氧化能力增强。

The paper discusses interaction of Cr and As with nutritional element: Ca, Mg, P and finds that Ca and Mg have decrease absorption of loessial soil to Cr and have increase to As.

初步发现钙、镁对黄土吸附Cr有减小作用，对吸附As有增大作用；Cr和As同时存在时，似乎在黄土中的吸附量有相互促进趋势。

There are some overlapped features between basal-like ca and metaplastic ca as Dr. Huang mentioned. There are no good IHC and genetic features to distingush these two for some case.

如Dr。 Huang所说，基底细胞样癌和化生性癌之间有重叠，在很多病例中，两者之间也没有很好的免疫组化和遗传学特征来进行区分。

In fact most cases of metaplastic carnoma belong to the spectrum of basal-like carcinomas based on the definition, such as spindle cell ca, squamous cell ca, adenosqumous.

实际上，按照定义大多数化生性癌属于基底细胞样癌的范围，如：梭性细胞癌、鳞状细胞癌和腺鳞癌。

Resting [Ca(2+)] and [Ca(2+)] transients evoked by large depolarizations exhibited similar properties in control fibres and in fibres loaded with tenth millimolar levels of the NOs inhibitor N-nitro-L-arginine.

对照组肌纤维与含有1/10毫克分子浓度的一氧化氮合酶抑制剂N-硝基-左旋精氨酸的肌纤维内，静息钙离子浓度及由大去极化诱发的钙离子浓度瞬变表现出了类似的性质。
