The invention discloses a scald powder, which is composed of powdery raw materials vitamin B2, chloramphenicol and dexamethasone, and the weight ratio among the components is 1-4:2-5:1-3. In order to improve the anti-inflammatory effect, 1-3 parts by weight of powdery raw material sulfadiazine is also added. The medicine of the invention is an external medicine, and the preparation method is simple, and the raw materials of each component are crushed and mixed. The medicine of the present invention has the advantages of fast recovery of poisonous water for treating burns and scalds, strong ability of dispelling poisons, and rapid growth of flesh and skin. For small-area scalds and burns, it can be cured after two times of medication; for large-area scalds and burns, after two to three times of medication, the poisonous water will no longer flow, and the wound will scab. . The medicine of the present invention has an effective rate of 100% in treating various types of burns and scalds, a cure rate of 100%, no side effects, no scratches on the flesh, no scars, unblocked pores and intact skin after recovery, and is effective in treating bruises, bruises, and sores. Same effect.

The invention discloses a preparation method of a composition for inhibiting wound cicatrix healing, comprising the following steps: (1) weighing L-selenium-methylselenocysteine ​​and transparent uric acid, and measure the ultrapure water according to the ratio, and dissolve the weighed L-selenium-methylselenocysteine ​​in the ultrapure water, stir, shear, and vibrate with an ultrasonic mixer Shake or vortex until L-selenium-methylselenocysteine ​​is completely dissolved in ultrapure water, then add the weighed hyaluronic acid, and swell at room temperature for 1-2 days to obtain the composition stock solution; ( 2) Under sterile conditions, pass the composition stock solution through a 0.22 μm microporous membrane to sterilize, subpackage under sterile conditions after sterilization, and store at 2-8°C to obtain the antibacterial Composition for wound cicatrix healing. The composition for inhibiting wound cicatrix healing prepared by the invention can effectively reduce wound cicatrix healing, and can reduce the pigmentation of the wound site in the wound shaping stage.

The invention discloses an amniotic membrane biological preparation and a preparation method thereof.
