应用扫描电镜和冷冻蚀刻电镜法观察了体外培养中ＬＡＫ细胞及对Ｒａｊｉ瘤细胞的杀伤攻击现象。文中首先描述了ＬＡＫ细胞及Ｒａｊｉ瘤细胞的超微形态，并重点探讨了对瘤细胞的杀伤效应。作者认为杀伤过程可分为两步：第一步系ＬＡＫ细胞主动性识别靠拢和贴附包围瘤细胞，第二步系攻击效应，攻击杀伤时主要表现为ＬＡＫ细胞以胞吐分泌方式对靶细胞进行穿凿性降解，导致靶细胞胞体空洞形成或贯通性损伤，最终引起靶细胞胞浆外泄而死。作者还就上述过程进行了讨论。
Scanning electron microscopy and cryo-etching electron microscopy were used to observe the in vitro killing of LAK cells and Raji tumor cells. The article first described the ultrastructure of LAK cells and Raji tumor cells, and focused on the killing effect on tumor cells. The author believes that the killing process can be divided into two steps: the first step is to identify and mobilize LAK cells move closer to the surrounding tumor cells attached to the second step attack effect, killing mainly when LAK cells to excrete secretion of target cells To wear chisel degradation, resulting in the formation of target cell vacuoles or through-cell damage, and ultimately cause the target cell cytosol leakage. The author also discussed the above process.
