METHODS: The vasodilatory effects of pinacidil and nifedipine were studied on rat aorta rings precontracted with 10 μmol·L -1 norepinephrine or 80 mmol·L -1 potassium chloride respectively.

大鼠离体主动脉环以10μmol·L－1去甲肾上腺素或80mmol·L－1KCl预收缩后，分别以不同浓度的吡那地尔和硝苯地平对抗。

Isolated rat pulmonary artery was perfused and the tension of the vessel was measured, the effect of isopropyl 3-(3,4-dihydroxyphenyl)-2-hydroxypropanoate on the pulmonary artery precontracted by noradrenaline and concentration-response curves of 5-hydroxytryptamine(5-HT), endothelin-1(ET-1), U46619 and KCl was also observed.

局壮性脑梗塞三天后，双侧大脑皮质内CA膨体的数量与膨体内CA的浓度均显著减少，梗塞灶边缘区可见大量CA颗粒聚集，其荧光特征与正常皮质内的CA颗粒不同；双侧大脑皮质内的去甲肾上腺素含量显著减少，多巴胺含量无明显变化。

The mechanism of co-fluorescence effect has been discussed. In chapter six, the new fluorescence enhancement phenomenon was observed by adding some crown ethers to samarium-thenoyltrifluoroacetone system.

在第六章中，研究发现当向钐-噻吩甲酰三氟丙酮中加入配位能力很强的大环配体冠醚时，冠醚对稀土有机配合物体系产生显著的荧光增强作用，其中冠醚二苯并18冠6后（DB18C6）可使钐-TTA二元配合物体系荧光强度增强280倍。

The test results of acute toxicity were examined with Pearson's degree of fitting. The results indicated that the silkworm was extremely sensitive to Chlorantraniliprole. The median lethal concentration (LC50) was 4.0905×10^(-3) mg/L and median lethal dose (LD50) was 1.1435×10^(-8) mg/larva for the 3rd instar newly exuviated larvae. No toxicity was observed when normal concentrations of Chlorantraniliprole were used to fumigate the silkworm rearing room. Both irrigation and leaf spraying with 1.25×10^(-4) mg/L Chlorantraniliprole solution showed strong systemic transmission properties in root, leaf and whole plant. The residual toxic period of this insecticide to silkworm was very long. Mulberry leaves sprayed with 1.25×10^(-4) mg/L Chlorantraniliprole solution could still cause 100% mortality of the 3 and 5 instar larvae after 60 d. Furthermore, toxic reaction was very quick. The poisoning symptoms emerged within 1~5 h after feeding on the poisonous leaves. The poisoned larvae experienced such symptoms as stopping ingestion, remaining still, vomiting slightly and body atrophy sequentially, and died ultimately.

食下毒力试验结果经Pearson拟合度检验表明，氯虫苯甲酰胺对3龄起蚕的食下致死中浓度(LC50)为4.0905×10^(-3)mg/L，致死中量(LD50)为1.1435×10^(-8)mg/头；药剂在常规浓度下对家蚕无熏蒸毒性；1.25×10^(-4)mg/L稀释药液对桑树根灌和喷叶处理，表现极强的根部、叶部和全株性内吸传导特性；药液对家蚕的残毒期很长，1.25×10^(-4)mg/L稀释药液田间喷雾桑叶，间隔60 d后采叶饲喂3龄和5龄蚕的死亡率均为100%，且中毒反应极快，添食毒叶后1~5 h出现中毒症状，经停止食桑、静伏、少量吐液、蚕体萎缩等过程后陆续死亡。

Our method featured employing the glycosyl donor with Bz as the protectivegroups and 0.05 equiv of TMSOTf as the promoter.

即：用苯甲酰基保护的三氯乙酰亚胺酯作给体，用5％当量的TMSOTf作促进剂，在室温下反应5min至15min。

目的 ：探讨甲胎蛋白异质体检测对原发性肝癌、良性肝病的临床应用价值。

In addition to the two axial ligations provided by His18 and Met80, the hydrogen bond and hydrophobic interactions between the heme and the protein polypeptide, the heme also covalently linked to the protein matrix through two thioether bonds which are formed between vinyl groups of the heme and cysteine residues of a classic Cys-Xaa-Xaa-Cys-His heme-binding motif of the polypeptide chain.

Cyt c是血红素蛋白中电子传递蛋白的典型代表，其辅基heme与蛋白肽链的结合除了来自heme轴向配体组氨酸(His18)和甲硫氨酸(Met80)的配位作用、氢键和疏水相互作用等非共价键作用方式外，血红辅基heme的两个乙烯基还与蛋白肽链上的结构片段域Cys-Xaa-Xaa-Cys-His中的两个半胱氨酸形成硫醚键以共价键方式相结合。
