将各种组织浸在化学试剂内,使组织或细胞内的蛋白质等成份迅速凝固或沉淀,不再发生变化,称之为固定。在病理组织切片的制作过程中,组织块固定是重要的一个环节,组织固定洽当与否,直接影响组织切片的质量,固定不佳的组织,除不能制出良好的切片外,还影响到不能及时或正确的作出病理诊断,因此,应当加以重视的,今将其要点及个人体会如下: Will be immersed in various chemical reagents within the organization or intracellular proteins such as rapid solidification or precipitation, no change, called fixed. Tissue block fixation is an important link during the production of pathological tissue slices. Whether the tissue is fixed or not will directly affect the quality of the tissue sections. Poorly fixed tissues can affect not only good slices but also Therefore, pathological diagnosis can not be made promptly or correctly. Therefore, important points should be given and personal experience as follows:
