Making a biopsy. Drawn (1) Material Fresh: Fresh drawn more better organization, human tissue in general from the body, the animal tissues fixed quickly after death, in order to ensure that the original morphological structure. (2) the size of the organization blocks: the ideal volume of tissue blocks 2.0cm × 2.0cm × 0.3cm, so fixative to penetrate quickly and evenly within the organization, but according to the producer of the material and for different purposes, tissue blocks The ideal size is also different, such as the production of pathological external examination, research section, the organization blocks can take 0.1 ~ 0.2cm thin you can, so you can shorten the time fixed dehydration transparent, if the production of teaching thick slices take 0.3 ~ 0.5cm, so You can create the same wax block teaching more slices. (3) Do not squeeze tissue block: tissue blocks were cut with scissors to be sharp, cutting can not move back and forth filing. Do not overtighten gripping tissue, so as to avoid leaving squeeze tissue, cell deformation. 2 derived tissue blocks should be taken regularly shaped, medium size, thickness consistency, usually 11.5mm × 11.5mm × 1.2mm. For some organizations drawn Shaanxi biopsy can be flexible, hard and tough confrontation desirable thinner tissue biopsy, such as leiomyoma tissues; and some loose tissue may be appropriate to get thicker, such as fat; derived bone tissue should be decalcified Shandong biopsy performed after the full, with a pin prick of light can penetrate to the bone tissue. Never squeeze drawn, or easy to make tissue compression deformation, structural damage. 3 organization after dehydration drawn in the process of various reagents can volatilize Jinan biopsy, resulting in reduced reagent concentration; when mixed with other reagents reagent or tissue debris, it can affect tissue dehydration, transparent, wax dipped or pollute the organization, and even misdiagnosed.
