Composition and environment-friendly specimen preserving fluid prepared from same

Abstract

The invention discloses a composition used for preserving a dead body and animal and plant specimens and an environment-friendly specimen preserving fluid which is prepared from the composition and has controllable fixation effect and relates to corrosion preservation, preservation, mould prevention and the like on the dead body and animal and plant specimens in medical teaching and scientific research. The composition comprises an anticorrosion and mouldproof active ingredient, a penetrating agent, a controllable fixation regulating agent and a solvent. The environment-friendly specimen preserving fluid is prepared by dissolving the composition in the solvent. The anticorrosion and mouldproof active ingredient is one plant extract, namely genipin. Compared with other existing specimen preserving fluids, the preserving fluid disclosed by the invention has a certain fixation effect and can be used for the corrosion prevention, preservation, mould prevention and the like of the dead body and animal and plant specimens. The preserving fluid disclosed by the invention has the characteristics of long corrosion prevention and mouldproof time, good effect, no formaldehyde, safety, no toxicity, non-volatile effective ingredients, available raw materials and low price.

Description

technical field [0001] The invention relates to the field of anticorrosion, preservation and mildew prevention of corpses and animal and plant specimens in medical teaching and scientific research, in particular to a composition and an environment-friendly specimen preservation solution with controllable fixation prepared by the composition. Background technique [0002] In the process of medical and biological analysis, observation, and research, animal and human tissues are fixed first, and then processed, observed, detected, and preserved. The fixation of animal and human tissue is to maintain the inherent shape and structure of cells and tissues through a series of treatments such as fixatives and dehydrating agents, so as to prevent bacterial corrosion and tissue autolysis, preserve the inherent substances of cells, make the tissues harden for cutting, and prevent Disease spread and enhanced staining, among other purposes. The most commonly used tissue fixative is form...

AI Technical Summary

Problems solved by technology

However, phenolic solutions can damage peripheral nerve endings, and phenols can easily be oxidized into benzoquinones. After a long time, there will be yellow-brown mud deposits in the corpse pool, which will reduce the antiseptic effect.

Commonly used salt solution is 20% sodium chloride solution. Due to the high concentration, the dehydration effect is too strong, and the corpse tissue may shrink due to dehydration, which brings certain difficulties to dissection.

Brogeramine solution is a fungicide with a common concentration of 0.1-0.2%. It is non-irritating, has low toxicity and has strong bactericidal power. However, because brogeramine is easily affected by organic matter and reduces the effect, it is contraindicated for use with many inorganic salts. Aluminum instruments should be avoided

Due to the high toxicity of heavy metal salts, their application is also greatly restricted

At present, there is no environmentally friendly specimen preservation solution on the market that can achieve the effect of specimen preservation without causing certain pollution to the environment.
