Calcium ionophore-induced tryptase release was inhibited 60% and 69% by 10 and 50 microM of DL, respectively, and anti-IgE-induced tryptase release was inhibited 33%, 47% and 66% for 1, 10 and 50 microM of DL.

研究发现浓度分别为1、10和50mM的DL分别使钙离子载体诱导的LTC4释放下降29%、35%和39%，分别使IgE诱导的类胰蛋白酶释放下降33%、47%和66%。

Results:The results showed that the apoptosis of neutrophiles was promoted by the treatment of 1 μg/ml LPS and 1 μm A23187,in 6 hours and 12 hours respectively.The apoptosis of neutrophil was markedly delayed by a PLA2 inhibitor,4-bromophanacyl bromid (p-BPB 0.01～1 mM).

结果：脂多糖（LPS 1μg/ml）和钙离子载体（A23187 1 μmol/L）等PLA2激动剂分别在共同培养6 h和12 h之内促进中性粒细胞凋亡，而PLA2阻断剂4-溴苯甲酰溴甲烷(p-BPB 0.01～1 mmol/L)可明显减弱上述激动剂的促凋亡作用。

A great interest has been evinced in the recent past to examine their role on the structure and properties of molecular complexes.

弱相互作用在生物分子识别，离子载体的选择性，晶体的组装，分子簇的形成等方面都起着决定性作用。

In this experiment, mouse eggs were cultured in a medium containing various reagents, including cycloheximide, Ca2+ ionophore A23187 and Ca2+ chelator.

本实验发现，CHX诱导的卵母细胞孤雌活化是Ca2+依赖性的，其效率可被钙离子载体A23187大大提高。

ADP and the calcium ionophore A23187 both stimulated platelet aggregation with a concomitant increase in intracellular calcium ion concentration.

ADP与钙离子载体A23187在诱导血小板聚集过程中都伴随细胞内Ca2+浓度增加。

Polyether antibiotics, also known as ionophore antibiotic, was widely used as high- efficiency, broad-spectrum anti-Coccidiostats, can also be used as animal growth-promoting agent.

中文摘要聚醚类抗生素又称离子载体抗生素，是目前广泛使用的高效、广谱抗球虫药，也可作为畜禽的促生长剂。

The use of penicillins in veterinary medicine does not present the same risks of hypersensitivity in animals as in humans. Although incidents of hypersensitivity have been recorded in horses and dogs, there are other materials which are toxic to certain species, e.g. the ionophore antibiotics in horses.

在兽用药中使用青霉素并不存在人用时过敏的危险，虽然有偶然的关于马和狗对青霉素有过敏的报导，有些药物对某些动物甚至是有毒性的，如离子载体抗生素对马。

So far they have been synthesized with various substituted groups and cavity-size of 4-20 phenol units. Calixarenes have been utilized in fields of complexation, catalysis, extraction, ionophore and so on.

目前已经合成出了4-20个苯酚单元所构成的不同环腔尺寸和具有不同取代基的杯芳烃：它已在配位、催化、萃取、离子载体、分离材料等领域得到了应用，在色谱中的应用也日益受到关注。

In darkness, the Ca〓-ionophore A23187 could mimic the effect of R, the volume and 〓 accumulation in protoplasts were 82. 91% and 90.62% respectively as those of R treatment when 5μmol/L A23187 was added to the medium.

在黑暗条件下，钙离子载体A23187（1～10μmol/L）可模拟红光的作用，5μmol/L A23187使原生质体膨大程度达红光处理的82.9l％，〓积累量达红光处理的90.62％。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
