Vocal Fold Augmentation with Beta Glucan Hydrogel Cross-Linked by γ Irradiation for Enhanced Duration of Effect: In Vivo Animal Study

Figure 2

Serial findings of the mice after subcutaneous injection of irradiated (left side) and nonirradiated (right side) β-glucan. The volume of the irradiated hydrogel was maintained until 2 weeks whereas the nonirradiated hydrogel was absorbed completely; the photographs from the left to right were serially taken immediately after injection, and at 3 days, 7 days, and 2 weeks after injection.
