应用体外培养的人小梁细胞，观察其吞噬乳胶微粒的能力。结果显示吞噬过程开始４小时内，吞噬功能随时间延长而增强；但吞噬过久细胞则出现变性或死亡；电镜示吞噬微粒后的细胞呈“激惹”状态。结合小梁细胞功能，对吞噬过程的重要性进行了讨论。
Human trabecular cells cultured in vitro were used to observe their ability to phagocytose latex particles. The results showed phagocytic function within 4 hours of phagocytosis began to increase over time; however, phagocytosis of too long cells resulted in degeneration or death; electron microscopy showed that the phagocytic particles were “provoked”. In connection with trabecular cell function, the importance of phagocytosis is discussed.
