现正广泛地研究吸入(气溶胶)接种法,以保证动物或人群免疫力之形成。许多作者的研究表明:以吸入法按种EV鼠疫活菌苗时,豚鼠和猿猴肺组织的反应过程在形态学上具有保护性的适应性,表现在网状组织系统细胞成份的增生。但是对吸入抗原时
Inhalation (aerosol) inoculation is now being extensively studied to ensure the formation of immunity in animals or populations. Many authors’ studies have shown that the morphological protective response of guinea pigs and simian lung tissues during inhalation of live attenuated vaccine strains of EV is manifested in the proliferation of cellular components of the reticuloendothelial system. But for antigen inhalation
