〔Abstract〕 To explore the effects of lipopolysaccharide⁃binding protein (LBP) on the skin reconstruc⁃tion process and to compare the differences in the healing rate and healing quality of scald wounds in C57BL/6J wild⁃type (WT) mice and LBP knockout ( LBP - / - ) mice were compared. Methods Based on WT mice and periodically after scald injury , and images were acquired and weighed. After the scar matured , the material was taken for HE staining , oil red staining and Masson staining , which were used to assess the quality of the newborn skin. Results The wound healing time of WT mice and LBP - / - mice was 18 days and 24 days , respectively. The results of pathological staining of skin tissue showed that compared with WT mice , the skin of LBP - / - mice had thinner new fat layer, fewer hair follicles and dysplasia of accessory glands. The mature scar tissue of LBP - / - mice was thicker and the collagen content was higher. Conclusion After scalding in LBP - / - mice , due to the lack of LBP , the wound healing rate is slowed down and the skin structure reconstruction is impaired.
