Objective To investigate the effect of lead acetate on the growth of cultured hippocampal neural cells and expression of nNOS.

目的 研究不同剂量醋酸铅对原代培养的海马神经细胞生长和神经元型一氧化氮合酶表达的影响。

Objective To study the damage effect of lead acetate on DNA and its mechanism and the changes of antioxidative enzymes in vivo.

Methods: The lead-poisoned mice were prepared by drinking water containing lead acetate, and the administration of Yinling Ⅰ or EDTANa2Ca to lead-poisoned mice was performed for 3 weeks. The number of white blood cell, the rate of carbon expurgation, the index of immune organ of mice were detected to evaluate the non-special immune function.

小鼠自由饮用醋酸铅溶液造模，分别予银苓Ⅰ号或依地酸钠钙治疗3周；观察外周血弊细胞计数、碳粒廓清指数K及校正指数α、免疫脏器指数等非特异性免疫功能指标的变化。

The pigment in colored cotton fibers was extracted by methanol at room temperature. The results of color reactions HCl-Mg reaction, NaBH4 reaction, NaOH reaction, FeCl3 reaction and Pb(Ac2 reaction of the pigment extractive showed that the pigment extracted by methanol was flavone or flavonol with two adjacent hydroxide groups (Table 2, Fig. 1). The results of UV spectral analysis further proved that the pigment extracted by methanol from brown fiber belonged to flavone with two adjacent hydroxide groups in B ring, and that from the green fiber contained not only flavone but also flavonols with two adjacent hydroxide groups both in A ring and B ring and indican replaced a hydroxide group at 3-site of A ring Fig.

通过盐酸－镁粉反应、四氢硼钠还原反应、碱反应、醋酸铅反应、氯化铁反应和紫外光谱吸收的分析表明，甲醇室温提取的棕色棉纤维色素可能是黄酮类化合物，B环上带有邻二酚羟基；甲醇室温提取的绿色棉纤维色素除黄酮类化合物外，还含有3-位羟基被糖甙化的黄酮醇类化合物，A、B环上都带有邻二酚羟基。

Aim To study the toxicity of the lead acetate on the fertilization ability of sperm and the development of early embryo in mice.

目的研究醋酸铅对公鼠精子受精能力及受精卵发育的毒性，为进一步研究提供依据。

The lead acetate could remarkably affect the fertilization ability of sperm and the development ability of embryo.

醋酸铅能明显影响小鼠精子的受精能力，并影响受精卵的进一步发育。

Another preparation is electrooxidation of lead acetate in acid solution.

另一种方法是在酸性溶液中对醋酸铅进行氧化。

Bw?d lead acetate for 30 days,followed by treatment with 30 mg/kg?

bw？d醋酸铅联合灌胃30 d，后用去离子水灌胃10 d；锌治疗组用15 mg/kg？

Objectives: Lead acetate is a kind of toxic metal and contributes to the damages of functions of many systems especially nervous system.

目的： 醋酸铅作为一种常见的金属毒物，对人体多种组织、器官造成损害，尤其对神经系统的损害更为严重。

Lead acetate and beryllium salts, along with most antifreeze compounds, are syrupy sweet and lethal.

醋酸铅和铍盐以及很多的低溶点的化合物像糖浆一样甜，并且是致命的。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
