1 材料与仪器 新鲜猪囊尾蚴、用全蝎乙醇提取物分别培养了4h、6h、8h的猪囊尾蚴,依次记为样品1、2、3、4,放入3％戊二醛中固定。日立835—50型氨基酸分析仪。美国DE—5000型原子吸收分光光度计。化学试剂均为优级纯或分析纯。2 氨基酸分析 取均重的猪囊尾蚴个体样品各4枚,采用保护性氧化、盐酸水解蛋白质法制备样品液,采用包括含硫氨基酸衍生物在内的50min快速分析法进行分析,结果见表1,图 1 Materials and equipment Fresh porcine cysticercosis cysticercus were cultured for 4 h, 6 h, and 8 h with ethanol extracts of whole fleas, and were recorded as samples 1, 2, 3, and 4, respectively, and fixed in 3% glutaraldehyde. Hitachi 835-50 amino acid analyzer. American DE-5000 type atomic absorption spectrophotometer. Chemical reagents are all grade pure or analytically pure. Two amino acid analysis were performed on four individual samples of cysticercus cellulosae. The protective solution was prepared by protective oxidation and hydrochloric acid hydrolysis. The analysis was performed using a rapid 50 min analysis method involving sulfur-containing amino acid derivatives. The results are shown in Table 1. , Figure
