Note ① community block fixation, dehydration, and wax dipped transparent quality directly affects the slice preparation. The difficulties encountered during the first slice should be noted from the above link to find the reasons in the previous sections. ② quality slicer is an important prerequisite for the preparation of high-quality slice. To use good quality slicer, slice standardized, well-maintained slicer. ③ via endoscopy, puncture tiny community acquired should be multi-faceted intermittent serial sections (general preparation of at least six wax, animal Specimens manufacturers supply, if necessary, produce additional photos). Need for special staining, immunohistochemical staining of cases, you can pre-wax backup. ④ slice should careful operation, to prevent being cut dicer. Embedded (1) conventional manual embedding: Meet the above "(i) manual" item. (2) community embedding machine, press the provisions relating to the operation of the manufacturer's instructions. ⑵ hollow organs: esophagus, stomach, intestines, etc. should be taken first, spread on a cork board for the mucosa, animal anatomical specimens manufacturers supply, and the edge of the specimen with a pin nailed to the board, and then placed in fixative, mucosal surface covers absorbent cotton or gauze, or mucous membrane face down dip and fixative. ⑶ Brain: The whole brain tissue fixation, downtown bottom up, the first in a long suture through the basilar artery rings, then holding hands has been injected into the brain tissue fixative container, then the suture ends up slightly Lift, animal embedded specimens manufacturers, by means of the buoyancy of water suspended in the brain tissue fixative, then the suture is fixed to the wall of the container. Brain tissue fixation time is required, specimen, usually 10 to 15 days, fixed one week should be replaced once the fixative. ⑷ the eye: eye surface structure is dense, fixative not penetrate, fixed corneal diameter should be done by a sagittal incision of the cornea, the small pieces of paper rolled into a predetermined thickness is inserted into the incision, thereby making the incision into the eye fixative inside, in order to facilitate fixation. ⑸ non-small whole organs directly with a sufficient amount of tissue fixative fixed.
