纯化布氏菌素(Purified Brucellin)为新制的一种细菌提取物,它的主要成份为热稳定性蛋白。对于布氏菌感染或曾接受过布氏菌活菌苗免疫之机体,作皮试抗原时,可引起特异的皮肤变态反应。其稀释液中含有微量酚作为防腐剂,评价它的质量优劣,首要的是它对动物和人体能否产生毒副反应,重复使用,能否使机体致敏;出现过敏反应。为此,在向布病防治工作中推广这一新制品之前,必需对其安全和毒副作出评价,以确保今后本品在全国各疫区使用时,人体不会受到伤害。因此,进行了这一方面的试 Purified Brucellin is a freshly prepared bacterial extract whose main ingredient is thermostable protein. For the brucellosis infection or have been exposed to the body of live bovine vaccine for skin test antigen, can cause specific skin allergies. Its diluent contains trace amount of phenol as a preservative to evaluate the quality of its advantages and disadvantages, the most important is that it produces toxic side effects on animals and humans, re-use, can make the body sensitized; an allergic reaction. To this end, in the brucellosis prevention and control work to promote this new product before the safety and toxic side must make an assessment to ensure that the future use of this product in all affected areas, the human body will not be harmed. Therefore, carried out this aspect of the trial
