Tissue sections refers to the biological tissue as materials handling for thin tissue sections, apply to a microscope slide to fit the observed. This is an important tool and method for histological development. Often associated with improved production techniques and microscopy slides and hair growth. Widely used in tissue sections, agronomy (plant pathology) and other areas of biology, medicine (pathology, infectious diseases, etc.). Slice slice species biology refers to the material tools (such as a blade, slicing machine) cut into sheets of suitable procedures to microscopic examination; or complete specimens after this procedure is also known as slices. Common types of slices, depending on the nature of materials and processing methods are: unarmed slices, slices of wood, wax buried slice, transparent method, dissociation method, smear method [1]. In terms of the more stringent definition, smear slides made law is often called smear, dissociation method, transparent method produced slide specimens not called slices. In accordance with the nature of the slide can be saved into temporary and permanent piece of sheet; terms of the use of tools and methods, there are sliced ??by hand or using a slicer ① fresh frozen cryostat sections 6 ~ 8μm thick pathological tissue sections, flat against. coverslip. ② drop staining: Frozen sections will have coverslips (sample side up) flat on the preheated dish (bottom cushion a wet filter paper), the incubation medium was added dropwise to cover all tissues, the temperature at 37 ℃ and incubated for 45 to 60 minutes (liver tissue slices manufacturers, myocardial tissue 15 minutes). ③ in saline rinse twice (Sway slice technique to prevent the off-chip). ④10% saline formalin fixed 10 minutes. ⑤15% alcohol immersion 5 minutes (in other secondary). ⑥ glycerogelatin mounted. ⑸ results: strong activity at blue particles (double A precipitation), the formation of purple monomethyl lower activity. In the light microscope, the enzyme activity in the lobular distribution is obviously zoning, surrounding band is stronger than the central belt. In cardiomyocytes longitudinal section, enzyme granules aligned along the long axis of myocardial cells, cardiomyocytes in the space adjacent to intercalated disk.
