补充资料:残质体
吞噬性溶酶体到达末期阶段时,由于水解酶活性下降,还残留一些未被消化和分解的物质,被保留在溶酶体内,形成在电镜下呈现电子密度较高,色调较深的残余物,这种溶酶体称为残质体(residual body),常见的残质体有脂褐色,含铁小体,多泡体和髓样结构等,有的残质体能将其残余物通过胞吐作用排出细胞,有的则长期存留在细胞之内而不被排出如脂褐素
1、 常含有脂滴的脂褐色
围以单位膜的小体,内容物电子密度高,色调深,常含有浅亮的脂滴,常见于神经细胞和心肌细胞中,如皮肤上的老年斑,即为脂褐素堆积而成。
2、内部充满铁颗粒的含佚小体
含铁小体(siderosome)被以单位膜,内部充满电子密度高的含铁颗粒,在正常的单核—巨噬细胞系统细胞中可见到含铁小体。在溶血的病人脾脏中明显增多。
3.由许多小泡构成的多泡体
多泡体外被以单位膜,内含许多小泡,小泡可能来自高尔基体或细胞吞饮的小泡。
4、膜性成份呈同心层状的髓样结构
髓样结构的特点是:它所含有的膜性成份呈同心层状,板状或指纹状等排列,可见于正常细胞(巨噬细胞)及病变细胞如肿瘤细胞和病毒感染的细胞。
