摘要：Sasa veitchii (S. veitchii) is a traditional herb derived from the bamboo genus, which is collectively called Kumazasa. Although Kumazasa extract is believed to have various effects on the skin, there is little scientific evidence for these effects. In this study, we aimed to obtain scientific evidence regarding the wound-healing and skin-moisturizing effects of Kumazasa extract. Kumazasa extract was applied to the skin of a mouse wound model for 14 days, and the wound area and dermal water content were measured. Mice treated with Kumazasa extract had smaller wound areas than control mice. The dermal water content in the Kumazasa extract-treated group was significantly higher than that in the control group. The mRNA and protein expression levels of cutaneous aquaporin-3 (AQP3), which is involved in wound healing and increases in dermal water content, were significantly increased by treatment with Kumazasa extract. Kumazasa extract-treated HaCaT cells exhibited significantly higher AQP3 expression and p38 mitogen-activated protein kinase (MAPK) phosphorylation than control cells. With continuous application, Kumazasa extract increases AQP3 expression and exerts wound-healing and moisturizing effects. The increase in AQP3 expression elicited by Kumazasa extract may be due to enhancement of transcription via activation of p38 MAPK signaling.
