作者等选择厚莢膜强毒菌株,应用血液馬丁琼脂,制成一种免疫效力比較滿意的菌苗,两次注射每次1毫升,可以抵抗7—9个M.L.D.强毒菌的攻击,免疫期最少可达100天(未作更长时間的测定)。作者等认为,莢膜物质可能在鸡霍乱菌苗的免疫中具有重要意义,故在創造有利于莢膜形成的条件以外,尽量避免或减少热和化学剂对此种有效抗原物质的破坏作用。此外,提高菌苗中的抗原浓度,借以增加抗原刺激的强度,似乎也是保証有效免疫的必要条件。

A new and simple method for bulk isolation and preparation of serum β-lipoprotein by pure chemical means was presented. By taking advantage of certain properties of the β-lipoprotein-dextran sulfate complex it was found possible to avoid ultracon- trifugation altogether.It was found that macromolecular dextran sulfate could interact specifically at neutral pH with serum β-lipoprotein to form an insoluble complex and that it did not react with serum α-lipoprotein or other serum proteins. The complex formed could be rendered soluble by increasing the ionic strength of the medium. The loosely combined macromolecular dextran sulfate was then removed by precipitating it with barium acetate, thus leaving the free β-lipoprotein in solution.The purity and properties of the isolated β-lipoprotein was characterized by means of paper electrophoresis, agar gel electrophoresis and immunoelectrophoretic and ultracentrifugal analyses. It was found that the isolated β-lipoprotein solution no longer containe an appreciable amount of dextran sulfate upon detecting the polyanions with acid polysaccharide dyes. On agar gel electrophoresis there appeared only one spot whose position corresponded to α_2-globulin. On paper electrophoresis there was revealed only one band corresponding to that of β-globulin of whole serum, whether it was stained with protein or lipid dyes. Upon ultracentrifugation with a maximum speed of 50,000 rpm it could float in a high density medium of 1.063g/ml. All the above data suggest that the isolated β-lipoprotein is quite pureUltracentrifugal analysis showed that the lipoprotein contained mainly the β-lipoprotein of S_f 2-6, but there was also a small amount of low density lipoprotein of higher S_f values. Immunoeletrophoretic analysis showed, however, only one precipitating arc with antiwhole serum, indicating that β-lipoproteins of different S_f values may have similar immunochemical properties.The newly prepared β-lipoprotein is transparent and light yellow in color and has 2 to 3sorption peaks in visible light, between 410mμ to 500mμ, and one in ultraviolet light at 275mμ. It can be stored at 2° to 4℃ for 14 days or concentrated at 4℃ without the formation of any precipitate.Finally, the characteristics of dextran sulfate-β-lipoprotein complex in concentrated salt solution was studied by stainning the protein and polyanions with Azo-carmine and Alcian Blue dyes on the same paper strip after electrophoresis. It was found that the complex was still in a state of combination and not at all dissociated.

In this paper, we report for thefirst time the mediation of cytotoxicimmune reactions against human livercancer cells in vitro by xenogeneic "im-mune" RNA. The human liver cancercell strain (BEL-7402) employed wasestablished in tissue culture in ourlaboratory by explant from a surgicalspecimen. The cell-mediated assayusing ~(125)I-iododeoxyuridine (~(125)IUdR)-labeled target cells was used for thestudies. Normal, nonimmune humanperipheral blood lymphocytes were con-verted into "killer cells", which effectedimmune cytolysis of human liver cancercells, by incubation with "immune"RNA extracted from the lymph nodesand spleens of sheep which had pre-viously been immunized with the hu-man liver cancer cells being studied.It was observed that the cytotoxicityindex of lymphocytes increased signi-ficantly after incubation with "immune"RNA in ten experiments. The controlRNA from sheep non-specifically im-munized with complete Freund's adju-vent did not enhance cytotoxicity indexof lymphocytes except in one experi-ment. The immune response mediatedby the "immune" RNA was abrogatedwhen the "immune" RNA was treatedwith RNase prior to incubation withlymphocytes. Treatment with DNaseor pronase did not effect the activityof the "immune" RNA. From thesestudies, it was demonstrated that thexenogeneic "immune" RNA couldtransfer the cell-mediated immunitydirected against the surface antigenson the human liver cancer cells tonormal human lymphocytes. Thus, itwould be suggested that xenogeneic"immune" RNA might be consideredas an approach to immunotherapy forhuman hepatocarcinoma.

从人肝癌细胞(BEL-7402)高度免疫过的绵羊的淋巴器官中抽提的肝癌“免疫”RNA,和正常人外周血淋巴细胞温育后,在体外能介导肝癌细胞的免疫细胞溶解。用5-~(125)碘-2′-脱氧尿嘧啶核苷标记人肝癌靶细胞的微量细胞毒性试验进行测定时观察到,正常人淋巴细胞经肝癌“免疫”RNA处理后,其细胞毒性指数在16次实验中有10次有显著增高,但是,在与对照RNA温育后其细胞毒性指数(除一次实验外)均未出现有显著意义的变化。肝癌“免疫”RNA在用RNA酶降解后,传递细胞毒性免疫反应的活性即消失,而用DNA酶或灰链霉菌蛋白酶处理,却仍保持这种传递能力。由此证明,异种“免疫”RNA能够把针对人肝癌细胞表面抗原的细胞免疫性传递给正常人淋巴细胞。
