Prostaglandin (PG) $E_2$ is an important mediator of skin wound healing without excessive scarring and gastric ulcer healing. However, $PGE_2$ has a short lifetime in vivo because it is metabolized rapidly by 15-hydroxyprostaglandin dehydrogenase (15-PGDH). Ethanol extract of Eriobotryae folium (EFEE) elevated intracellular and extracellular $PGE_2$ levels in HaCaT cells and inhibited 15-PGDH ($ED_{50}$ : $168.4{\mu}g/mL$) with relatively low cytotoxicity ($IC_{50}$ : $250.0{\mu}g/mL$). Real-time PCR analysis showed that mRNA expression of cyclooxygenase (COX)-1 and COX-2 enzymes were increased and prostaglandin transporter (PGT) was decreased in HaCaT cells by EFEE. Moreover, wound healing effect of EFEE ($168.4{\mu}g/mL$) was comparable to that of TGF-${\beta}1$ (300 pg/mL) as a positive control. These results demonstrate that EFEE may be valuable therapeutic materials for the treatment of $PGE_2$ level dependent diseases.
