In the toxicity inhibition test, the accumulated amount of oxygen uptake of BAC was decreased with the increase of Monochloroacetic acid dosages, especially when concentration of MCAA over 100 μg/L. It can be concluded that high concentration of MCAA can inhibit the microorganism's metabolism.

在毒性抑制方面，随著添加加氯消毒副产物一氯醋酸的浓度增加，微生物之累积摄氧有降低趋势，尤其是浓度高於100 μg/L后更为明显，显示MCAA在高浓度下对BAC附著微生物的代谢机制有抑制作用。

The peridotitic xenoliths can be divided into two groups based on their composition s, namely, the H-type and L-type.

Whole-cellpatch-clamp technology demonstrated that VDPG (1g/L) had notsignificant effects on the delayed-rectified K~+ current, TTX-sensitive Na~+ current and high-voltage-activated Ca~(2+) current of rat dorsalroot ganglion cells. The fast transiet K~+ current of cottonbollworm dorsal DUM cells, the fast transiet K~+ current, Na~+ current andhigh-voltage-activated Ca~(2+) current of Periplaneta Americana dorsalunpaired median cells were also not significantly affected byVDPG at the same concentration. However, VDPG had significant effecton the fast transiet K~+ current of Pieris rapae. The VES had not significanteffects on the high-voltage-activated and low-voltage-activated Ca~(2+)current of rat DRG cells.

膜片钳电生理实验显示1g／L毒囊粗毒对蜚蠊DUM神经元的快瞬时钾电流、钠电流、高电压激活的钙电流，对棉铃虫快瞬时钾电流和大鼠DRG细胞延迟整流钾电流、TTX-S型钠电流、高电压激活的钙电流均无明显作用，却对菜青虫快瞬时钾电流有明显作用；电刺激粗毒对大鼠DRG细胞低电压和高电压激活的钙通道无明显作用。

It reports that L-ascorbic acid's polarographic oxidation wave in acid solution and its application.

报道了L-抗坏血酸在酸性溶液中的极谱氧化波及其应用。

In the presence of L-isoproterenol (through local infusion into area CA1), the theta-pulse stimulation with the parameter of 10 Hz, 150 pulses/train, 1 train, a frequency weakly modifying synaptic strength, induced a robust LTP, and this effect was blocked when DL-propranolol was co-administered. By contrast, the theta-pulse stimulation with the parameter of 5 Hz, 150 pulses/train, 3 train, a frequency strongly modifying synaptic strength, induced a significantly smaller LTP when DL-propranolol was administered into area CA1. Accordingly, DL-propranolol impaired rat's spatial learning in the water maze when infused into area CA1 20min pretraining.

正常情况下对突触传递效能仅有微小调制作用的10Hz的θ节律刺激（每串150个脉冲，1串），在CA1区局部给予L-异丙肾上腺素后，显著地诱导出LTP，这一效应可被DL-心得安所阻断；相反，正常情况下对突触传递强度有显著调制作用的5Hz的θ节律刺激（每串150个脉冲，3串），在CA1区局部给予DL-心得安后，所诱导出的LTP被显著压抑。

MethodsIn the solvent of 1 mol/L NaOH, using the reaction of the water-soluble phenolic acidity in Radix Salviae Miltiorrhizae and the NaNO_2-Al(NO_3)_3, the total components of water-soluble phenolic acidity in Radix Salviae Miltiorrhizae injections and drip solution(calculated with protocatechualdehyde) were determined by colorimetric s...

方法利用丹参中水溶性酚酸类成分与亚硝酸钠和硝酸铝溶液在碱性条件下的显色反应，比色法测定该两种制剂中水溶性酚酸的总量。结果原儿茶醛在3.336~14.46mg/L范围内呈良好的线性关系，回归方程为：A=0.02777C+0.01279(r=0.9996)，加样平均回收率为100.8%，RSD为0.96%。结论该法简便快速，结果准确，重现性好，可用于该制剂的质量控制。
