西尼罗病毒空斑形成试验方法的建立与应用

目的建立西尼罗病毒的空斑形成试验方法，应用于病毒滴度测定和实验感染蚊虫及来亨鸡血液样本中病毒的定量检测。方法将稀释的样本接种常规制备的Veto细胞单层，用琼脂糖凝胶覆盖，孵育一定时间后，加中性红染色，计数空斑数，计算空斑形成单位。结果在琼脂糖凝胶中西尼罗病毒可形成直径大约1～3mm的圆形或类圆形空斑。20％病毒鼠脑悬液的病毒滴度为10^7空斑形成单位。感染蚊虫样本和来亨鸡血液样本也出现典型的空斑。结论建立了西尼罗病毒的空斑形成试验方法，该方法可应用于病毒滴度测定和实验感染蚊虫及来亨鸡血液样本中病毒的定量检测。

Detection of the cyanobacterial hepatotoxins microcystins

Concern regarding the presence of microcystins in drinking water and their possible contamination in food (e.g., salad vegetables, fish, shellfish) has resulted in the need for reliable methods for the detection and accurate quantification of this class of toxins. Currently, routine analysis of microcystins is most commonly carried out using high-performance liquid chromatography with photodiode array detection (HPLC-PDA), although more sensitive biological assays such as antibody-based ELISAs and protein phosphatase inhibition assays have also proven useful. However, many of these methods have been hindered by the availability of a wide range of purified microcystins. Although over 60 variants have now been reported, only a very small number are commercially available and calibrated standards are not yet obtainable. This has led to the common practice of reporting microcystin-LR equivalence regardless of which variant is present. The increased availability of HPLC with online mass spectral analysis (HPLC-MS) may facilitate more accurate detection of toxin variants but as several microcystins share the same molecular mass, definitive identification can be difficult. A further difficulty in analyzing microcystins is the requirement for sample processing before analysis. Solid phase extraction (SPE) is typically used to enrich environmental concentrations of microcystins, or to eliminate contaminants from complex samples such as animal and plant tissues. Recently, new technologies employing recombinant antibodies and molecularly imprinted polymers have been exploited to develop assays and biosensors for microcystins. These novel detection systems are highly sensitive, often do not require sample processing, and offer a simpler, less expensive alternative to analytical techniques. They have also been successfully employed in solid phase extraction formats for the concentration and clean up of environmental samples before HPLC analysis.
