Objective:
To observe the changes of expression of phosphorylation c-Jun NH2-terminal kinase (p-JNK) during the skin burned wound healing in patients and discuss the molecular mechanism of burned wound healing.
Methods:
The staining intensity and distribution of p-JNK were detected by immunohistochemistry and routine histology in burned skin samples of 12 patients and normal skin samples of 12 control subjects.
Results:
In normal skin, the positive signals of p-JNK were mostly localized in basal layer cells of the epidermis, with a positive rate of (8.8+/-1.3)%. In the burned group, the positive signals of p-JNK were mainly localized in the epidermal cells and some inflammatory cells, with a significantly higher positive rate of (31.2+/-3.3)% than the normal group(P<0.01).
Conclusion:
The changes of p-JNK expression after skin burned might correlate with wound healing.
