Thermosensitive Hydrogels as a Controlled Release System for Alkannin to Improve Localized Treatment of Candida Vaginitis after External Beam Radiotherapy in Vitro and in Vivo.

External beam radiotherapy increases the risk of Candida vaginitis in cervical cancer patients, which brings a lot of insufferable influence to their life. Here, we explored the efficacy of alkannin in the treatment of Candida vaginitis after external beam radiotherapy. We exploit thermosensitive hydrogel-mediated alkannin as the topical formulation in a rat model established in our work. Periodic acid-Schiff of vaginas indicated little Candida albicans adhered to the vaginal tissue in treatment group. Additionally, hematoxylin and eosin stain revealed that inflammatory response of high dose alkannin was reduced. Above all, the animal model was first established in our work for the clinical desire. Our results suggested the promising application of alkannin for the disease with satisfying fungicidal activity and anti-inflammatory activity.
