Abstract
We treated 57 patients with abnormal sensation in the throat without inflammation on inspection. 34 patients were treated with lysozyme chloride (Acdeam®) commbined with minor tranquilizer (Group A) and 23 patients were treated with minor tranquilizer only (Group B). Use of only minor tranquilizer was effective for 43.5%, on the other hand, combined use of minor tranquilizer and lysozyme chloride (Acdeam®) was 73.5%. Statistical difference was found between Group A and Group B. Therefore, lysozyme chloride (Acdeam®) is effective for patients with abnormal sensation in the throat without inflammation on inspection, because they have surely occult inflammation in the upper respiratory organ.
