It is shown ultrastructurally that intravenously injected and liposome-entrapped dichloromethylene diphosphonate (DMDP) causes marked damage to marginal zone macrophages in the mouse spleen which finally results in the elimination of these cells. Marginal zone lymphocytes are also affected by this treatment, probably as a result of action of the enzymes released by dying macrophages. Marginal zone macrophages largely disappear, 24 h after i.v. injection, leaving an open-meshed reticulum in which a few viable and necrotic lymphocytes are present. The proposed method to eliminate macrophages for some time may be used to study functional aspects of these cells in vivo.
超微结构显示,静脉注射并包裹于脂质体中的二氯亚甲基二膦酸盐(DMDP)对小鼠脾脏边缘区巨噬细胞造成显著损伤,最终导致这些细胞被清除。边缘区淋巴细胞也受到这种处理的影响,这可能是垂死巨噬细胞释放的酶作用的结果。静脉注射后24小时,边缘区巨噬细胞大量消失,留下一个开放网孔状的网状结构,其中存在一些存活和坏死的淋巴细胞。这种在一段时间内清除巨噬细胞的方法可用于研究这些细胞在体内的功能方面。
