本文采用14种吸入抗原:如螨、屋尘、霉菌、花粉、枕垫料、羽毛、棉絮、烟等的浸出液注射至左右上臂外侧皮内,形成小皮丘,15分钟后查看结果,用此法对114例患儿进行观察,106例阳性(92.9%)。其中对一种抗原呈阳性反应者28例,二种抗原阳性者86例,三种以上抗原阳性者42例。在各种抗原中,对尾尘过敏最高(74.5%),其次为花粉类(43.4%),螨(36.8%)。本文还对抗原阳性者进行特异性脱敏治疗,能坚持注射、并可作为考核对象者51例,显效32例(62.7%),好转13例(25.4%),无效6例(11.9%),有效率为88.1%。治疗前后作了嗜酸性白细胞绝对计数及免疫指标测定,前者多呈中度升高,提示大多数患者属于变态反应性哮喘。免疫指标在治疗前测定与正常组相比无明显差别;治疗后IgA有明显上升,提示经免疫治疗后能激发机体产生阻断性抗体,使IgA值增高。
In this paper, 14 kinds of inhaled antigens: such as mites, house dust, mold, pollen, pillow material, feathers, cotton wool, smoke and other leaching solution injected into the lateral arm of the left and right upper arm, the formation of small hillock, 15 minutes after the results, 114 cases of children were observed, 106 cases were positive (92.9%). Among them, 28 cases were positive for one antigen, 86 cases were positive for two antigens and 42 cases were positive for three or more antigens. Of the various antigens, the highest sensitivity to tail dust (74.5%), followed by pollen (43.4%), mites (36.8%). In this paper, 51 patients with persistent positive antigen were treated with specific desensitization, which can be inspected and injected. Among them, 51 (62.7%) were markedly effective, 13 (25.4%) were improved, 6 were ineffective (11.9%), The effective rate is 88.1%. Before and after treatment made eosinophils absolute count and immune index determination, the former mostly moderately elevated, suggesting that most patients belong to allergic asthma. Immunological indicators in the treatment before the test was no significant difference compared with the normal group; IgA after treatment increased significantly, suggesting that after immunotherapy can stimulate the body to produce blocking antibodies, IgA value increased.
