Abstract

Normal guinea-pig serum was found to have a cytotoxic effect upon several newly induced mouse lymphoblastic leukaemias and on normal mouse thymocytes. This reaction was complement dependent, and cross-absorption experiments showed that the reactivity could be abolished by absorption with any susceptible cell type. It was concluded that normal guinea-pig serum contained a natural antibody which reacted in common with normal mouse thymocytes and certain lymphomas. The growth of lymphomas which had proved highly sensitive to guinea-pig serum was inhibited by guinea-pig serum . In contrast, lymphomas showing insensitivity to guinea-pig serum were also insensitive to it . It is suggested that the inhibition of lymphoma growth was due to the natural cytotoxic antibody present in guinea-pig serum.

摘要

研究发现,正常豚鼠血清对几种新诱导的小鼠淋巴细胞白血病以及正常小鼠胸腺细胞具有细胞毒性作用。该反应依赖补体,交叉吸收实验表明,用任何敏感细胞类型进行吸收均可消除其反应性。由此得出结论,正常豚鼠血清中含有一种天然抗体,它能与正常小鼠胸腺细胞和某些淋巴瘤发生共同反应。对豚鼠血清高度敏感的淋巴瘤的生长受到豚鼠血清的抑制。相比之下,对豚鼠血清不敏感的淋巴瘤对其也不敏感。有人认为,淋巴瘤生长受到抑制是由于豚鼠血清中存在天然细胞毒性抗体。
