Compared with classical cytotoxic T lymphocytes , NK cells are superior in the following aspects: NK cells are among the first cell types to be activated after intracellular pathogen stimuli, the activity of NK cells peaked between 1 to 3 days, retained during the first 7-10 days, and the T cells response emerged only after 7 days when the NK cell responses begin to decline; though comprising of only 10%-15% of peripheral lymphocytes, NK cells mobilize most of the cell populations in a strong and high level response to different invasions, and act as key factors at early defense before a specific immune response could mount, while only certain clones were involved in T cell response; NK cells kill virus-infected or malignant transformed cells without pre-sensitization and without restriction by major histocompatibility antigen, which is usually a mechanism of immune escape to T cell recognition by virus-infected or tumor cells, thus NK cell in complementary with T cells play crucial roles in tumor and virus eradication.
NK细胞以其强大的细胞毒活性为特征,与细胞毒性T细胞相比,NK细胞具有如下特点:NK细胞虽然只占外周血淋巴细胞的10-15%,但是对刺激性因素产生应答的过程十分迅速,一次可以调动大多数细胞共同参与,而不是几个克隆的活化,免疫应答的强度高;病毒感染或恶性转化细胞的一个主要特征是细胞表达的MHCⅠ类分子下降或消失,并借助这一机制逃避特异性T细胞应答的识别,NK细胞介导的杀伤活性无需抗原刺激,不受MHCⅠ分子表达的限制,从而与T细胞应答互为补充发挥免疫防御的功能;NK细胞的免疫活性可以被多种细胞因子上调,其中IFNα,IL-2,IL-12,IL-15和IL-18具备更强的作用;NK细胞具有强大的细胞因子分泌功能,对于启动T细胞特异性应答必不可少。

Based on the previous literatures, the following major innovation works were carried out in this dissertation:(1) The derivatization reaction conditions of ephedrine and pseudoephedrine with sensitive derivation reagent in aqueous system were studied and two new methods were developed for the assay of them by microemulsion electrokinetic chromatography and micellar electrokinetic chromatography with LIF detection. The sensitivity and analysis times were greatly improved compared with the previous reports;(2) A new method of CZE with indirect LIF detection was developed for the simultaneous determination of six coumarin compounds (esculin, esculetin, isofraxidin, genistein, naringin and sophoricoside) with fluorescein as the probe. The proposed method enlarges the application range of LIF detector, and provides new approach for the analysis of certain compounds difficult to derivatize;(3) Based on the above research, an MEKC with indirect LIF detection method for the simultaneous determination of adenine and guanine in DNA extracts from fungus, maize and soybean was established;(4) A new method for the investigation of the complexes formed between human serum albumin and ampicillin sodium under the simulated physiology conditions using laser light scattering technique was developed.

The background of the play is this: Some time after Oedipus was banished from Thebes, his two sons, Eteocles and Polyneices, quarreled over the rightful succession. The kingship went to Eteocles, rightfully; Polyneices fled to Argos, the traditional enemy of Thebes, and returned with seven armies, each of which attacked Thebes at one of its seven gates.
