文蛤多肽体外对人肺癌A549细胞的抑制作用

我们已从文蛤肉中提取得到1种具有抗癌活性的多肽,命名为Mer2.本文报道Mer2对体外培养的肺癌A549细胞的生物学效应.采用溴化二苯偶氮盐(MTT)法检测Mer2对肺癌A549细胞的抑制效果,并应用细胞形态观察法、Hoechst荧光染色和流式细胞术等方法,探讨了Mer2对细胞形态、细胞周期的影响.结果表明,Mer2对体外培养的肺癌A549细胞的生长有较强的抑制作用,对作用含量和时间均具有一定的依赖性.Mer2使细胞形态发生明显变化,明显地出现凋亡峰,但并没有出现明显细胞周期阻滞现象.这表明文蛤多肽可能通过诱导细胞凋亡从而抑制癌细胞的生长

Characteristic Evaluation of Endothermic Fuel for Regenerative Cooling System

There exists the regenerative cooling system using endothermic fuel for refrigeration as one of the means for cooling heat load of hypersonic vehicle. The hydrocarbon fuel has been known to exhibit the endothermic thermal decomposition reaction. Cooling capacity of the regenerative cooling becomes about three times by employing the endothermic reaction. In the present study, endothermic thermal decomposition characteristics were verified experimentally and analytically for the fuels tested in order to construct the regenerative cooling system using the endothermic thermal decomposition by the catalytic reaction of methylcyclohexane (MCH) and bioethanol (BE). From the experimental results, it was found that the decrease of initiation temperature in the decomposition of fuels was about 350 K for MCH and 150K for BE with the catalysts, respectively.特集 : 航空宇宙機システム研究センターにおける開発研究2 : 1. オオワシII飛行にむけて並びに関連技術の研究開発（推進系
