Administration of a single dose of 1 mg carrageenan to mice cause a temporary blockade of hepatic phagocytosis of 51Cr-labelled sheep erythrocytes (SRBC) and a prolonged reduction in the number of splenic plaque-forming cells (PFC) against SRBC. The in vitro responses to phytohaemagglutinin (PHA) and SRBC were also suppressed, whereas the response to the T cell-independent antigen DNP-Ficoll was not affected. Other in vitro experiments have shown that responses of normal cells can be actively suppressed by macrophages from carrageenan-treated mice and the possible mechanisms of this suppression are discussed.
给小鼠单次注射1毫克角叉菜胶会导致对51Cr标记的绵羊红细胞(SRBC)的肝脏吞噬作用暂时受阻,以及针对SRBC的脾斑块形成细胞(PFC)数量长期减少。对植物血凝素(PHA)和SRBC的体外反应也受到抑制,而对T细胞非依赖性抗原DNP-菲可的反应不受影响。其他体外实验表明,来自角叉菜胶处理小鼠的巨噬细胞可主动抑制正常细胞的反应,并对这种抑制的可能机制进行了讨论。
