ABSTRACT
OBJECTIVE@#To explore the microvessel counts and the expressions of interleukin-8 (IL-8), monocyte chemoattractant protein-1 (MCP-1), and macrophage inflammatory protein-1 ( MIP-1) alpha mRNA in the pathological scar tissues.@*METHODS@#Immunohistochemical method of avidin-biotin complex was used for microvessel counts on the routinely formalin-fixed and paraffin-embedded sections of specimens of hypertrophic scars, keloids, normal skin, and surgical scar, and in situ hybridization for the expressions of IL-8, MCP-1, MIP-1alpha mRNA.@*RESULTS@#The microvessel counts as well as the positive rates and the scorings of IL-8, MCP-1, and MIP-1alpha mRNA were significantly higher in pathological scars than those in the normal skin and surgical scar (all P < 0.05). The microvessel counts were significantly higher in the positive cases of IL-8, MCP-1 and MIP-1alpha mRNA than those in the negative ones (P < 0.05). The close positive correlations were found among the microvessel counts and the expressive scorings of 3 factors (P < 0.05). The close positive correlations were also found among the expressive scorings of IL-8, MCP-1, and MIP-1alpha mRNA in pathological scars. Microvessel counts were significantly higher in hypertrophic scars with the course less than 1 year than those with the course more than 1 year.@*CONCLUSION@#IL-8, MCP-1 and MIP-1alpha play important roles in promoting the neovascularization of pathological scars.
