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

Figure 5

H&E staining of subcutaneous mouse tissue. The nonirradiated hydrogel caused more inflammatory reactions in the surrounding fat than did the irradiated hydrogel (black arrowhead: inflammatory cell infiltration into the fatty tissue; : the space in which the hydrogel was located).
