开放性肺结核病人经适当地抗结核药物治疗后,会很快地失去传染性。这一观点已被广泛接受。为了使这一观点得到实验证实,而进行了如下动物实验。首先取3例未经治疗的开放性肺结核病人的痰液给豚鼠皮下注射,在结核菌素转阳6周后进行尸检,均有全身性结核病变。实验2、采集7例病人经过4周标准化疗(R、H、E)后的痰,分别注入7只豚鼠,其中6只在尸检中发现结核病灶。而将痰培养呈弱阳性反应(只有3个
Open tuberculosis patients who receive proper antituberculosis medications can quickly lose their transmissibility. This view has been widely accepted. In order to make this point of view confirmed by experiments, the following animal experiments were carried out. First of all, 3 cases of untreated sputum from patients with open pulmonary tuberculosis were injected subcutaneously into guinea pigs and autopsy was performed 6 weeks after tuberculin transfection. All of them had systemic tuberculosis. In Experiment 2, seven guinea pigs were injected into the sputum of seven patients after 4 weeks of standard chemotherapy (R, H, E) respectively. Six of them were found to have tuberculosis at autopsy. The sputum culture was weak positive reaction (only 3
