抗蝮蛇毒磷酸二酯酶单克隆抗体的制备及鉴定

从蝮蛇毒中提取磷酸二酯酶,用此酶免疫BALB/c小鼠,取其脾细胞与小鼠骨髓瘤细胞Fo融合,以间接ELISA检测杂交瘤细胞培养上清液和小鼠腹水中的特异性抗体,其效价分别为1∶128和1∶51 200.抗原阻断试验结果表明,此抗体对蛇毒磷酸二酯酶具有特异性.该杂交瘤细胞株定为G_8,该株单抗属鼠IgG_(2a)亚型,经体外持续培养6个月,其分泌抗体性能稳定.     

LDPE／CPE／炭黑三相复合导电体系的电学性能

研究了ＬＤＰＥ／ＣＰＥ／炭黑三相复合导电体系的导性能和电流－电压特性。实验结果表明复合体系具有明显的导电渗滤效应，在共混比ＬＤＰＥ／ＣＰＥ＞５０／５０时，导电性能随ＣＰＥ含量增加而显著提高，这主要是由于炭黑粒子在ＬＤＰＥ和ＣＰＥ两组分分中的分布不均匀性所致。     

米非司酮作用于兔输卵管收缩活动与Ca^2＋关系的研究

通过“结合化学分离与原子吸收分光光度法”对Ca^2 含量测定和离体输卵管肌条收缩记录方法，研究米非司酮（Ru486)对增加假孕（4d)兔输卵管平滑肌收缩频率，而不改变其收缩张力和振幅时与Ca^2 之间的关系，结果提示：（1）Ru486对输卵管分泌液和组织内Ca^2 的含量分布无明显影响；（2）Ru486具有降低细胞外液高Ca^2 浓度促Ca^2 内流，而使收缩增强的效应，且能协同Ca^2 通道阻断剂（Verapamil)抑制细胞外Ca^2 内流，而致收缩减弱的效应。

Capacitively coupled electrical stimulation of bovine growth plate chondrocytes grown in pellet form

Pellets formed from isolated bovine growth plate chondrocytes were grown in various capacitively coupled electrical fields. The signals chosen were 0, 10, 100, 250, 500, 750, 1,000, and 1,500 V peak-to-peak, 60 kHz. The effect on cell proliferation and matrix production of these different voltages was determined by [3H]thymidine and [35S]sulfate uptake, respectively, Cyclic AMP assays were done to determine if increases in either thymidine or sulfate uptake were associated with changes in cAMP levels. Significantly increased cell proliferation occurred at 500, 750, and 1,000 V peak to peak. The calculated electric fields were 1.5 to 3.0 x 10(-2) V/cm. Proliferation was significantly inhibited at 1,500 V peak-to-peak with a calculated field of 4.5 x 10(-2) V/cm. Little if any change was seen in cAMP levels at 30 or 60 min following application of the appropriate electric signals.     

Estimating neuron dendritic length in 3D from total vertical projections and from vertical slices

The recently developed method of total vertical projections is illustrated to estimate the total dendritic length of a human Substantia Nigra neuron. Next, the length of the different orders of dendritic branches, and the mean segment length for each order - commonly regarded as important parameters in neuron physiology - are also estimated. Finally, it is shown how to estimate the mean dendritic length in a population of neurons from vertical slices of arbitrary and unknown thickness. Being unbiased and highly efficient, the proposed methods offer interesting alternatives to current procedures used for the metric analysis of neuron arborizations.
