Abstract
Electron microscopic studies confirm and extend the conclusions derived previously from a quantitative biochemical study of the phagocytosis of polystyrene and polyvinyltoluene latex beads by Acanthamoeba (1). Latex beads 1.305, 1.90, and 2.68 micro in diameter are ingested individually, with each bead tightly surrounded by a membrane derived from the plasma membrane. Latex beads 0.557, 0.264, 0.126, and 0.088 micro in diameter are accumulated at the surface of the ameba and then phagocytosed, with many beads tightly packed within one membrane-bounded vesicle.
摘要
电子显微镜研究证实并拓展了先前通过对棘阿米巴吞噬聚苯乙烯和聚乙烯甲苯乳胶珠的定量生化研究得出的结论（1）。直径为1.305、1.90和2.68微米的乳胶珠被单独摄取，每个珠子都被源自质膜的膜紧密包围。直径为0.557、0.264、0.126和0.088微米的乳胶珠在阿米巴表面聚集，然后被吞噬，许多珠子紧密堆积在一个有膜包被的囊泡内。
