Background/Aims: Our previous study confirmed that Loureirin B (LB) can inhibit hypertrophic scar formation. However, the mechanism of LB-mediated inhibition of scar formation is still unknown. Methods: Immunohistochemistry was used to detect expression of Col1, FN and TGF-β1 in skin and scar tissue. Fibroblasts were stimulated with TGF-β1 to mimic scar formation. LB or MAPK inhibitors were used to study the pathways involved in the process. Western blotting was used to evaluate the expression of p-JNK, p-ERK, p-p38, Col1 and FN. The contractile capacity of fibroblasts was evaluated using a gel contraction assay. Tissues were cultured ex vivo with LB to further investigate the participation of ERK and JNK in the LB-mediated inhibition of scar formation. Results: FN and Col1 were up regulated in hypertrophic scars. LB down regulated p-ERK and p-JNK in TGF-β1-stimulated fibroblasts, while levels of phosphorylated p38 did not change. The down regulation of p-ERK and p-JNK was associated with a reduction of Col1 and FN. Similarly, inhibition of ERK and JNK down regulated the expression of Col1 and FN in TGF-β1-stimulated fibroblasts. LB down regulated protein levels of p-ERK and p-JNK in cultured hypertrophic scar tissue ex vivo. Conclusions: This study suggests that LB can inhibit scar formation through the ERK/JNK pathway.

For the past 3 years, Nottingham City Hospital Burns and Plastic Surgery Unit have been using silicone gel in addition to, or as an alternative to, accepted methods of treating hypertrophic scarring. This paper outlines the history, properties and indications for use of silicone gel. Its findings result from a retrospective study based largely on clinical observations.
