Conference report: Third annual young researcher forum of the Japan Society of Medical and Pharmaceutical Sciences for Traditional Medicine

Four young researchers presented their studies in the field of traditional Japanese herbal medicine (Wakan‐yaku) at the third annual young researcher forum entitled “Respecting and Breaking Traditions,” held 1 week before the 2022 annual meeting of the Japan Society of Medical and Pharmaceutical Sciences for Traditional Medicine. Dr. Yokogawa presented her research focusing on the mechanism of the Ayurveda drug‐eluting string, Kshara Sutra, in treating anal fistulas, reporting on its effects on the anal tissue in an anal fistula rat model and its antibacterial activity against Escherichia coli and Staphylococcus aureus, the causative organisms of anal fistulas. Mr. Nakamichi presented his research focusing on the relationship between the efficacy of Kampo medicines with anti‐obesity effects and intestinal microbiota composition. His results partially revealed that bofutsushosan and boiogito affect lipid metabolism in mice and correlate with the intestinal microbiota composition. Dr. Manse reported the anti‐inflammatory activity of diterpenoid components in Enmei‐so (Isodonis Herba), revealing its novel inhibitory activity on nitric oxide released from activated macrophages and on inflammatory cytokines, and identified active components contributing to the inhibition and the mechanism of action. Mr. Yoshikawa reported the anticancer activity of small molecular compounds isolated from the medicinal plants, Valeriana fauriei and Hypericum erectum. His results suggest that five compounds may increase the sensitivity of human cervical carcinoma cells to adriamycin via HSP105 expression suppression. The event was conducted online, and included 78 participants. We intend to hold and improve this forum in 2023 and the future.
