硝基四氮唑兰(N.B.T)是一种细胞免疫功能检查法,是检测中性粒细胞杀菌功能的一种简易方法,中性粒细胞在杀菌过程中、能量消耗骤增,糖代谢活跃,葡萄糖分解中间产物葡萄糖—6磷酸氧化脱氢成为戍糖,所脱的氢被外加的四氮唑兰染料接受,使淡黄色的四氮唑兰还原为兰黑色的点状或块状甲(月替)颗粒沉积于中性粒细胞浆内,在油镜下容易识别,当细菌感染时,本试验阳性细胞增高,在病毒感染时阳性细胞正常,或减少;为了探讨流行 Nitroblue tetrazolium (NBT) is a cellular immune function test, is a simple way to detect neutrophil bactericidal activity, neutrophils in the sterilization process, the surge in energy consumption, active glucose metabolism, Glucose decomposition intermediate glucose -6 phosphate oxidative dehydrogenation to become sugar, the removal of hydrogen by the addition of tetrazolium dye to accept, the light yellow tetrazolium reduced to blue-black dot or massive armor (month For the particles deposited in the neutrophil cytoplasm, easy to identify under the oil microscope, when the bacterial infection, the test positive cells increased positive cells in the virus infection normal, or reduced; in order to explore the epidemic
