3 dehydration dewaxing agent without a net or too old, they tend to cause broken or thick slices, stained adverse affect diagnosis; there flyer sliced ??incomplete, often poor tissue fixation, dehydration is not complete, resulting in paraffin tissue can not be immersed internal cause; wax block central depression appears to produce white halo between the organization and the wax, generally by excessive tissue dehydration, dipping wax temperature is too high pathology What does it mean, for too long causes tissue to become brittle, hard and embedded tissue stiffness hardness greater than paraffin, wax blocks pop cause tissue slices or sliced ??wrinkled, easy to expand and see the water naturally disengaged [1]. Therefore, the amount should be based on the size of the specimen or observation biopsy tissue handling of practices, the timely replacement of reagent biopsy, master dehydration time, do a thorough dehydration, dipping wax temperature control organization fit. 6 slices toasted slices of roast temperature is also very important, I will slice hospital pathology department with an oven set at a temperature of 80 ℃, 20min, so as not to cause tissue contraction, we would not have off-chip. 7 hematoxylin staining is the world's only conventional dye nucleus. Many of its recipes pathology report, Harris recipe most commonly used. The advantage of this solution is that you can use after the match, dyeing and strong, but it can easily form a precipitate, and easy to aging shortcomings can not be ignored. This room after a long practice, improved preparation of dye improves the quality of HE staining. Harris summed up with a method to improve the following: (1) the volume of potassium aluminum sulfate in distilled water, heated to completely dissolve, Akzo wood finishing each 10g aluminum potassium sulfate heat to boil 2 minutes. (2) Take away quickly put the fire source of iodine, sodium 0.1g, shake cooling (accelerated oxidation of iodine, sodium, shortening the dosing process).
