Mast Cell Infiltration in the Myocardium After Localized Cardiac RT

Adult female rats were administered 24 Gy of localized cardiac radiation therapy (RT) or sham treatment, and at 10 weeks post-treatment, their hearts were harvested. Mast cells were stained using toluidine blue and quantified. The figure shows a significant increase in mast cell infiltration after RT, n = 4/condition. Values are mean ± SEM. SS = salt-sensitive.
