Since there exists some disadvantages such as poor mechanic properties and much higher burning rate pressure exponents (?1) in the fundamental formulations, this work is devoted to the improvements of combustion characteristics and mechanic properties of LOVA propellants. The effects of the crystal shape, size and contents of nitroamine particles, the types of binder, plasticizer and surface-active agents and the contents of NC on combustion performance are studied by closed bomb tests. In the mechanic properties tests, the effects of the types of binders, plasticizers and solid fillers, the interaction between binders and solid fillers and technological procedures on propellant mechanic properties are researched.

As results, TEM showed characteristic ultrastructure morphology of apoptosis cell with chromatin marginal condense, nucleus pycnosis, mitochondrion vacuoles and cell shrinkage in IR injury group and no apoptosis cells in control group. Increased TUNEL-positive cell and typical DNA laddering were found and cells apoptotic rate were approximately 20% by flow cytometry assay in experimental groups.

值得探讨。本试验通过流式细胞仪、生物电镜、TUNEL法、RT-PCR以及DNA电泳等试验方法研究了带血供同种异体骨移植过程的细胞凋亡现象，并检测了Fas、FasL、Caspase-1、Caspase-3、Bcl-2等凋亡相关基因在IR损伤时的表达及变化情况，初步探讨了骨移植时IR损伤中细胞凋亡的发生机制及其在IR损伤中的生物学意义，希望为今后更深入的研究打下一定基础。

This non-specific antigen detects reagin , an IgM or IgG immunoglobulin present in the plasma or serum of patients with syphilis and occasionally present in the serum or plasma of individuals with other acute or chronic conditions. If reagin is present it binds to the cardiolipin antigen resulting in flocculation.

对个别病人应用同一种试验方法做连续的血清学检测，最好在同一个实验室进行，VDRL和RPR都是同样有效的方法，但是，由于RPR的滴度常常比VDRL的滴度略微偏高，两种方法的定量结果不能直接比较。

Results: The result indicated ELISA method was more sensitive, but the reaction time was much longer, the process is more complex, and the special instrument operation was needed. The agglutinates testing method was simple, their results could be observed in the short time visually, but the sensitivity was nothigh.

结果：几种方法结果表明，ELISA方法更灵敏，但反应时间长，过程复杂，需特殊仪器操作；而凝集试验方法简单，可在短时间直接观察结果，但灵敏度不高。
