Problems solved by technology

In addition, the specimens preserved in formaldehyde solution for a long time will have mildew, yellowing, and hardening of the specimens.
The concentration of formaldehyde solution will also decrease due to the volatilization of formaldehyde, the inhibitory effect on bacteria will be reduced, and the function of preserving specimens will gradually be lost.

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.

[0018] The present invention provides a preservation solution of human anatomical viscera specimens, calculated in parts by weight, the preservation solution comprises the following components:

[0019]

[0020] Animal specimens are rich in water and polar substances,

[0021] Diethylene glycol has a strong dehydration effect, which can remove the water on the cell surface, loosen the molecular structure of the protein, and denature and solidify the protein to act as a preservative; polyethylene glycol 400 is a colorless, odorless, viscous It can be mixed with diethylene glycol arbitrarily, and the solution formed by it is relatively stable, so it is a high-value solvent and preservation solution component; polyethylene glycol 400 has high moisture retention and plays a role in prev...

Abstract

The invention relates to a human anatomy internal organ specimen preservation solution. The preservation solution comprises diethylene glycol, polyethylene glycol 400, an osmotic regulator, a preservative, a mildew inhibitor and a color retention agent. The preservation solution has the advantages of no contain formaldehyde, low volatilization, no irritating odor, low toxicity, high safety, no pollution to the experimental environment, good preservation effect, no mildews during long-term preservation, and realization of soft texture and good color of specimens.

Description

technical field [0001] The invention relates to the field of anatomy, in particular to a preservation solution for human anatomical viscera specimens. Background technique [0002] As we all know, to preserve the specimens in a transparent liquid to keep the specimens as original as possible is beneficial to scientific research, teaching and people's viewing. The liquid currently used is mainly formalin solution, which is injected into the blood vessels of the human body. prevents the decay of corpses. Formalin specimen preservation solution has a good fixation effect, which is due to the large amount of formaldehyde combined with the functional groups of the specimen protein, and after long-term storage, it further polymerizes to form paraformaldehyde. This process makes it form a moderate cross-link between protein peptide chains, which can not only kill bacteria, but also maintain the tissue shape of the specimen. However, formaldehyde and benzene have been identified a...
