Embodiment Construction
[0033] The content of the present invention is further explained or illustrated by the following examples. However, the provided examples should not be construed as limiting the protection scope of the present invention.
[0034] 1) Perfusion: After shaving the hair of the corpse, removing dirt and oil stains on the skin, and disinfecting, the corpse is shaped according to the anatomical posture with a bandage or plastic film, and the femoral artery is inserted through the femoral artery to perfuse the fixative. 15% (weight ratio, hereinafter the same) formalin solution, and play a preservative role at the same time. The amount of fixative perfused through the femoral artery of the corpse should be sufficient, generally calculated according to height and weight, and the amount of 15% (weight ratio, the same below) formalin solution perfused is generally 10,000-20,000ml, so that the tissue can be better fixed.
[0035] During this step, you will directly contact the blood, bo...

The invention relates to an AIDS based preparation method of three-dimensional faulting specimens for researching and teaching. The preparation method is characterized by comprising the following steps: preparing the operation environment and operation conditions; shaping a corpse specimen of an AIDS patient, and pouring a formalin solution through femoral artery intubation for anticorrosion; after pouring the formalin solution into the corpse specimen, placing for 10-12 hours, and fully soaking the corpse in a formalin solution with the weight ratio of 5% for fixing for 6 months; positioning and scribing on the corpse specimen surface in the methyl violet elastic line method; placing the corpse specimen at the environment of -30 DEG C for freezing for 7-10 days; sawing the corpse specimen through a wood serrulate band saw for traverse, coronary and sagittal faulting specimens; conducting pathologic sampling on the faulting specimens; processing and preserving the specimens. The AIDS three-dimensional faulting specimens prepared through the preparation method realize the general perfect combination of the faulting specimens, CT images and pathological corroboration.
Description
technical field [0001] The invention relates to a preparation method of scientific research and teaching specimens, in particular to a preparation method of AIDS-based scientific research and teaching specimens. Background technique [0002] AIDS, namely human acquired immunodeficiency syndrome (acquiredimmune deficiency syndrome, AIDS) is widely prevalent in the world and has become a major problem that seriously threatens human health. In the initial stage of human immunodeficiency virus (Human Immunodeficiency Virus, HIV) infection, it is mainly the replication of the virus and the destruction of lymphocyte subsets T lymphocytes, such as CD4, CD8 and other immune function cells, which lead to the decline of cellular immune function. As the course of the disease progresses to the AIDS stage, the immune system function is suppressed or lost, and the patient is vulnerable to the invasion of various condition-causing pathogens and fatal opportunistic infections or tumors. Su...
