Abstract EN
Purpose.
Macrophages serve as sweepers of microbes and inflammation-derived wastes and regulators of inflammation.
Some traditional Japanese medicines are reported to have adjuvant effects by modifying macrophages.
Our aim was to characterize the actions of jumihaidokuto (JHT) for treatment of skin inflammations including acne vulgaris, in which Propionibacterium acnes has pathogenic roles.
Methods.
Dermatitis was induced in rat ears by intradermal injection of P.
acnes.
JHT or prednisolone (PDN) was given orally, and ear thickness and histology were evaluated.
The effects of constituents and metabolites of JHT on monocytes were tested by cell-based assays using the human monocytic THP-1 cell.
Results.
JHT and PDN suppressed the ear thickness induced by P.
acnes injection.
Histological examinations revealed that JHT, but not PDN, promoted macrophage accumulation at 24 h after the injection.
PDN suppressed the macrophage chemokine MCP-1 in the inflamed ears, while JHT did not affect it.
The JHT constituents liquiritigenin and isoliquiritin increased expression of CD86 (type-1 macrophage marker) and CD192 (MCP-1 receptor) and enhanced phagocytosis by THP-1.
Conclusions.
JHT suppressed dermatitis, probably by enhancing type-1 macrophage functions, with an action different from PDN.
JHT may be a beneficial drug in treatment of skin inflammation induced by P.
acnes.
