Abstract

The invention provides an application of pearl oyster small molecule peptide in skin wound repair. The pearl oyster small molecule peptide has a new application of repairing skin wounds. The preparation method of the pearl oyster small molecule peptide comprises the following steps: S1, preparing a pearl oyster zymolyte; and S2, selecting a ceramic membrane with a pore diameter of 0.05-0.5 mu m, performing full filtration, separating the material by adopting ultrafiltration membranes with different molecular weight cutoff, collecting peptide fragments with different molecular weights, including any one of bioactive peptide with the molecular weight of less than 3000Da, bioactive peptide with the molecular weight of 3000Da-5000Da and bioactive peptide with the molecular weight of 5000Da-10000Da, and performing freeze-drying to obtain the pearl oyster small molecule peptide. The invention provides a new application of the pearl oyster small molecule peptide in preparing a medicine for repairing skin wounds such as skin burn, wound, burn and scald, the effect of the pearl oyster small molecule peptide is obviously superior to that of the medicine in the prior art, the wound is quicklyrepaired, no scar is left, and the effect of promoting wound repair is more obvious.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and in particular relates to the application of a pearl oyster small molecule peptide in skin wound repair. Background technique [0002] Worldwide, more than 40 million people suffer from skin trauma each year. If the damaged skin cannot be repaired in time, the wound will be easily infected and become a chronic wound, severe trauma or even life-threatening. A good remodeling effect will reduce skin scars and even achieve scarless healing. [0003] Wound healing mainly includes four periods: hemostasis and coagulation, inflammation, proliferation and tissue remodeling. After the body suffers trauma, platelets are activated and secrete related factors to promote blood coagulation into thrombus to achieve coagulation and stimulate the body to produce inflammatory reactions. During the inflammatory phase, the immune system engulfs tissue fragments and kills environmental pollutants such as...
