This study was carried out to investigate the
wound healing effect of caffeic
acid in
skin-incised
mice. Caffeic
acid showed significant effects on anti-inflammatory activity and
wound healing, such as
myeloperoxidase activity,
lipid peroxidation,
phospholipase A2 activity and
collagen-like
polymer synthesis, in incised-
wound tissue. On the other
hand, it significantly stimulated
collagen-like
polymer synthesis in NIH 3T3
fibroblast cells, while inhibited both
silica-induced
reactive oxygen species generation and
melittin-induced
arachidonic acid release and
PGE2 production in
Raw 264.7 cells, and
histamine release in RBL 2H3
cells stimulated by
melittin or
arachidonic acid. Therefore, caffeic
acid appears to have a potent
antioxidant and anti-inflammatory effect in
cell culture system, which may be related to
wound healing in
skin-incised
mice.
