A simple and sensitive method is described for quantitative analysis of chlorpromazine in blood, serum, urine and tissue homogenate. The chlorpromazine cation radical produced by adding perchloric acid and 2,3-dichloro-5,6-dicyano-p-benzoquinone to the sample can be detected by the ESR method at room temperature. The sensitivity limit is 10 ng, that is, 20 μl of the solution containing 0.5 μg chlorpromazine/ml. The time needed for the measurement is within 10 min. The chlorpromazine radical thus produced is very stable; for example, 95% of the radical was observed after 24 h. The advantage of this method is discussed by comparing with the ordinary spectrophotometry which requires the purification of the sample. 相似文献

With deeper integration into the global economy and expanded penetration by multinational firms and other nonChinese actors
following accession to the WTO, skills in bureaucratic entrepreneurship are not likely to be sufficient by themselves to bring
about China’s sustainable development. In today’s interdependent and highly competitive trade, economic-cooperation, and resource-limited
environment, sustainable development requires that subnational managers also possess transnational competence in collaborating
with, negotiating with, and transforming foreign counterparts. However, survey research among Chinese executives based in
Shanghai revealed that only a small proportion of the reporting current and future managers recognized the growing importance
for China of an interculturally competent workforce. Without increased attention to enhancing the transnational competence
of government and state-enterprise managers, peaceful and ecologically sound development will be difficult to sustain given
the demands of multinational production chains, global resource constraints, and the challenges involved in managing transnational
relations in the interest of China’s long-term economic progress.

以30日龄仔猪睾丸组织块为培养对象,应用飞利普TECNAI10电子显微镜对培养前后的生精细胞类别进行了观察,对培养后的组织块进行生精细胞分化程度鉴定,建立了仔猪睾丸组织生精细胞爬片体外培养模型。培养前后电镜观察及HE染色结果显示,培养前细胞种类主要有2种:支持细胞和精原细胞,有少数几个初级精母细胞;培养第20 d的睾丸组织块HE染色观察到3个精子细胞,电镜观察到2个精子细胞。证实,在没有添加睾酮的情况下,此培养体系能够提供睾丸组织块生精细胞分化所需要的条件,使非精子细胞类生精细胞减数分裂为精子细胞。 相似文献

以陕西8株鸡传染性支气管炎病毒(AIBV)分离株M蛋白的基因序列为基础,应用DNAStar软件中的MegAlign模块对其进行了同源性分析;用Kyte-Doolittle方法、Jameson-Wolf方法、Karplus-Schulz方法、Plot-Emini方法和Garnier-Robson方法综合预测了其中4株代表毒株的M蛋白B细胞抗原表位和二级结构。结果,8株AIBV的M蛋白主要在10~40 aa和90~175 aa处存在无规律的点突变,与参考毒株H52、M41、SAIB20、LX和Gray的M蛋白的核苷酸序列和预测的氨基酸序列的同源性分别介于87.4%~99.5%和96.3%~99.5%;分离株间的核苷酸序列和预测的氨基酸序列同源性分别介于91.8%~99.8%和95.4%~100%。4株代表株的M蛋白B细胞优势抗原表位都在159~164 aa和181~193 aa肽段区(这2个区域都包含了无规则卷曲和β-转角结构)或其附近。结果表明,AIBV分离株的M蛋白基因相对保守,只存在无规律的点突变,该变异对AIBV M蛋白B细胞表位的稳定性无影响。 相似文献

We investigated the differences in the levels of carboxyhemoglobin (COHb), cyanide (HCN) and petroleum fuels (gasoline and kerosene) between left and right ventricular bloods from fire victims. COHb was slightly, and HCN and petroleum fuels were markedly higher levels in the left than those in the right. These effects were so called 'first pass phenomena' due to the circulation, diffusion and metabolization before the deaths of fire victims. 相似文献

Blood previously acidified with aqueous saturated ammonium chloride solution was extracted with ethyl acetate. The dried extract was subjected to acetonitrile–hexane partition. The acetonitrile portion was analysed for the presence of acidic and neutral drugs by HPLC–DAD (200 mm×2.1 mm I.D. microbore ODS-Hypersil column) and GC–FID (25 m narrow-bore×0.25 mm I.D. HP-5 column with 0.33 μm film thickness). The protocol was found to be suitable for both clinical toxicology (including emergency toxicology) and postmortem toxicology. At least 66 drugs of interest were unequivocally identified by RRTs (HPLC) and UV spectra (DAD) match while another 12 were unequivocally identified by double RRTs match (HPLC and GC). Quantitation was facilitated by incorporating calibration blood standards in each assay batch. The five drugs most commonly encountered in clinical blood specimens (1150 cases) were: paracetamol (47.4% of the cases); chlormezanone (6.6%), theophylline (1.74%), naproxen (1.65%) and mefenamic acid (1.56%). The following drugs were detected in toxicologically significant quantities in postmortem blood specimens (245 cases): phenobarbitone (1.22% of the cases), naproxen (0.82%), chlormezanone (0.82%), theophylline (0.82%), carbamazepine (0.41%) and paracetamol (0.41%). 相似文献
