现代免疫学的迅速发展,推动了基础医学和临床医学的研究和发展,同时,也促使人们研究、试制和生产更理想的免疫生物制剂。牛脾转移因子是其中的一种。其理化和生物学指标均能达到或超过人脾转移因子,初步临床试用已获得满意的疗效。而且,牛脾转移因子的材源充足、价格便宜、生产工艺简单,更无污染HBV之危险。因此认为,本研究所提供的方法具有实用价值,预料经济效益十分显著。 The rapid development of modern immunology has promoted the research and development of basic medicine and clinical medicine, and at the same time, it has also prompted people to study, trial-manufacture and produce more ideal immunobiological preparations. Bovine spleen transfer factor is one of them. Its physical and chemical and biological indicators can reach or exceed the human spleen transfer factor, the initial clinical trials have been satisfactory results. Moreover, adequate sources of bovine spleen transfer factor, cheap, simple production process, but also no danger of contamination of HBV. Therefore, the method provided by this research is of practical value and the expected economic benefits are very significant.
