Cooling Sodium Alginate Has Stronger Analgesic Effect with Respect to Adverse Reaction-induced Pain in Radiotherapy

In the treatment of cancer,radiotherapy is equally important to chemotherapy,and the pain arising from the adverse reactions of esophagitis and stomatis is treated with sodium aliginate (AL-Na).We decided to try cooling AL-Na because it was felt that doing this would enhance the analgesic effect.When cooled,the time of adhesion to the affected part was longer than that for AL-Na at room temperature and the pain relieving effect was greatly enhanced.
