Traditional Chinese medicine type nano-titanium dioxide specimen preservation solution

Abstract

The invention discloses a traditional Chinese medicine type nano-titanium dioxide specimen preservation solution, the raw materials of which include: honeysuckle flower extract, radix salviae miltiorrhizae extract, nano-titanium dioxide, glacial acetic acid, auxiliary ingredients and water. With the glacial acetic acid, the honeysuckle flower extract, the radix salviae miltiorrhizae extract and the nano-titanium dioxide as main ingredients of the specimen solution, the traditional Chinese medicine type nano-titanium dioxide specimen preservation solution can expand tissues in a specimen whichare rich in fibers, and can also fix protein and fat and eliminate bacteria; and with ethanol and glycerol as the auxiliary ingredients, while fixation is accelerated, an organic solvent in the solution can be adsorbed. The preservation solution disclosed by the invention can ensure that specimens do not have the phenomenon of rotting within a year, moreover, the skin, mucous membranes and the like of the specimens do not have obvious changes, no mould can be produced in the preservation solution, specimen fixation is good, and the specimen preservation solution does not have irritating odor.

Description

technical field [0001] The invention relates to the technical field of biological anatomy, in particular to a traditional Chinese medicine nano-titanium dioxide specimen preservation solution. Background technique [0002] In clinical anatomy experiments, it is usually necessary to soak the specimens in the preservation solution to achieve the purpose of preserving the experimental specimens for a long time and fixing proteins and fats. Since the discovery of formaldehyde as an effective preservative in 1886, formaldehyde has been widely used as a specimen preservation solution fixative to preserve tissues, organs and whole remains. The advantages of the traditional specimen preservation solution using formaldehyde as an antiseptic fixative are that it is cheap, has strong bactericidal ability, has a thorough antiseptic effect, can inhibit the growth of mold and yeast, has a good effect on fixing and hardening tissues, and can remove the bacteria produced in the remains of t...

Problems solved by technology

The advantages of the traditional specimen preservation solution using formaldehyde as an antiseptic fixative are that it is cheap, has strong bactericidal ability, has a thorough antiseptic effect, can inhibit the growth of mold and yeast, has a good effect on fixing and hardening tissues, and can remove the bacteria produced in the remains of the decay process. The amine odor and the operation method are simple and the dosage is small, but formaldehyde is volatile and highly toxic, which greatly irritates the respiratory mucosa and skin of the experimenters; long-term exposure can also cause damage to multiple systems and organs, and even has certain effects. Carcinogenicity; and the maintenance of the color, texture and tissue elasticity of the specimen is poor. With the gradual development of the fields of medicine, science and technology, and environmental protection technology, the traditional specimen preservation solution and the specimens preserved by the traditional preservation solution have gradually been unable to satisfy people's scientific research and teaching.
