变态反应一、什么是变态反应? 变态反应,或称超敏反应,是机体对某些抗原物质产生的异常增高的免疫反应。这种反应超过了正常的生理范围,导致组织损伤和功能障碍,因而发生各式各样的变态反应性疾病。例如,有的人注射青霉素时发生过敏性休克,有的人吃鱼、蟹、蛋等食物发生腹痛、吐泻或气喘、荨麻疹等。这些都是变态反应。 Allergies First, what is the allergic reaction? Allergy, or hypersensitivity, is the body’s abnormal immune response to some of the antigen substances. This reaction exceeds the normal physiological range, resulting in tissue damage and dysfunction, resulting in a variety of allergic diseases. For example, some people experience anaphylactic shock when injecting penicillin. Some people eat fish, crabs, eggs and other foods for abdominal pain, vomiting and diarrhea or asthma, and urticaria. These are allergies.
