Abstract
The invention discloses auricularia polytricha glycopeptide with a lead removing function and a preparation method and application thereof. The technical scheme provided by the invention is the application of glycopeptide in preparing a medicine for treating lead poisoning, wherein the glycopeptide is named APL and is derived from auricularia polytricha; the N-terminal sequence of the APL is shown as a sequence 1 in a sequence table. The APL contains mannose, rhamnose, glucose, galactose, xylose, glucuronic acid and galacturonic acid. Experiments prove that compared with a model group, each dose group containing the glycopeptide APL extracted by the invention can effectively remove lead in liver, particularly the APL high dose group has a liver lead removal rate of 17.96 percent and an effect superior to a positive medicament liver lead removal rate of 16.01 percent. The glycopeptide APL of the present invention can be used for treating lead poisoning.
Description
Technical Field
The invention relates to the technical field of biology, in particular to auricularia polytricha glycopeptide with a lead-removing function and a preparation method and application thereof.
Background
Lead is a toxic heavy metal, has the characteristics of high utilization rate, low recovery rate and difficult degradation, and is extremely harmful to human bodies. In addition to lead released from the environment due to natural causes, a great amount of pollution is generated by human activities such as raw ore mining, smelting and production of lead-containing products, and the lead pollution situation is very severe due to weak environmental awareness, imperfect environmental protection mechanism and the like. Lead pollution is mainly present in the atmosphere, soil and food, and lead in the environment can finally enter human bodies through biological enrichment or direct contact.
Lead metabolism in human body is quite slow, half-life period in blood and soft tissue exceeds one month, lead is mostly combined with erythrocytes or distributed in each tissue, the content of lead in liver and kidney is highest, lead has toxic effect on each system and organ, and lead mainly affects nervous system, reproductive system, cardiovascular system, urinary system, blood and the like. Lead has direct toxic effects on central and peripheral nervous systems, and can cause character changes such as depression or hyperactivity, mental retardation, sensory functions such as visual, auditory, olfactory disorders, and muscle damage. The existing medicines for treating lead poisoning mainly comprise chelating agent medicines, metallothionein, antioxidants and traditional Chinese medicines, different treatment methods can cause other problems while discharging lead, the chelating agent medicines can discharge trace elements necessary for a human body while discharging lead, some medicines can cause the phenomena of nausea, dizziness and weakness, even kidney injury, the natural extract has definite lead discharging curative effect, and the natural extract has great potential in research and development with small toxic and side effects.
