Embodiment 1~ Embodiment 5
[0023] Embodiment 1~Example 5: Take the pathological tissue taken from human liver as an example
[0024] A method for processing pathological specimens, which is to sequentially fix, dehydrate, transparent, soak in wax, embed, section, stain and seal the pathological tissues obtained to obtain the pathological specimens, wherein:
[0025] Fixing: the pathological tissue was fixed with a fixative solution for 6 hours, and the composition of the fixative solution is shown in Table 1;
[0026]Dehydration: Use 50% ethanol, 60% ethanol, 75% ethanol and absolute ethanol as dehydrating agents in order of volume concentration, and gradually replace the water in the fixed pathological tissue. The dehydration treatment time of the above concentrations is 1~ 3 hours;
[0027] Transparency: The dehydrated pathological tissue is sequentially immersed in 50% xylene and 100% xylene solution for transparency treatment, wherein the 50% xylene solution transparency treatment time is 2 to 4 ho...
Embodiment 6~ Embodiment 11
[0035] Embodiment 6~Example 11: Take the lung pathological tissue taken from the human body as an example
[0036] A method for processing pathological specimens, which is to sequentially fix, dehydrate, transparent, soak in wax, embed, section, stain and seal the pathological tissues obtained to obtain the pathological specimens, wherein:
[0037] Fixation: Fix the pathological tissue with a fixative solution for 8 hours. The fixative solution is composed of 13g of atractyl alcohol, 7ml of ethoxylated acetylene glycol, 13g of chlorogenic acid, 40g of polyvinylpyrrolidone, and sodium chloride. 32g, ethyl acetate 6ml, pure water to 1000ml;
[0038] Dehydration: Use 50% ethanol, 60% ethanol, 75% ethanol and absolute ethanol as dehydrating agents in order of volume concentration, and gradually replace the water in the fixed pathological tissue. The dehydration treatment time of the above concentrations is kept for 2~ 4 hours;
[0039] Transparency: The dehydrated pathological t...
Embodiment 12~ Embodiment 17
[0047] Embodiment 12~Example 17: Taking the brain pathological tissue taken from the human body as an example
[0048] A method for processing pathological specimens, which is to sequentially fix, dehydrate, transparent, soak in wax, embed, section, stain and seal the pathological tissues obtained to obtain the pathological specimens, wherein:
[0049] Fixation: Fix the pathological tissue with a fixative solution for 10 hours. The fixative solution is composed of 13g of atractyl alcohol, 7ml of ethoxylated acetylene glycol, 13g of chlorogenic acid, 40g of polyvinylpyrrolidone, and sodium chloride. 32g, ethyl acetate 6ml, pure water to 1000ml;
[0050] Dehydration: Use 50% ethanol, 60% ethanol, 75% ethanol and absolute ethanol as dehydrating agents in order of volume concentration, gradually replace the water in the fixed pathological tissue, and keep the dehydration treatment time of the above concentrations for 3 hours ;
[0051] Transparency: The dehydrated pathological t...
