The preparing results and conditions were studied. After extracting and purification, HA was detected through ultraviolet spectra and infraction spectrum, and its content and purity were tested by carbazole and Elason-Morgan, respectively. This results indicated that significant quantities of HA could be prepared in fresh pigskin with biologic enzyme, and the pure HA was cosmetic grade and food grade.展开更多

Methods: from January 2016 to December 2020, 40 burn patients admitted to the emergency department of our hospital were selected and divided into control group (n=20) and experimental group (n=20) by random number table method. The control group was treated with conventional burn treatment, and the experimental group was treated with irradiated pigskin technology. The curative effect and complications of the two groups were compared. Results: after treatment, the effective rate of burn treatment in the experimental group was significantly higher than that in the control group, and the incidence of complications such as invasive infection, scar and water electrolyte disturbance was lower, and the wound healing and hospitalization time were shorter, the difference was statistically significant (P < 0.05). Conclusion: irradiated pigskin technology in emergency department has outstanding clinical effect, high safety and high clinical application value.展开更多
