课文(一):吃鸡蛋也会过敏

记得四个月前,我第一次交代老妈给儿子吃鸡蛋。那天晚上下班一进家门,老妈就兴奋地对我说:“宝宝今天好厉害,一个蒸蛋吃掉大半儿个呢!”我听了好高兴,心想以后可以每天给他加餐了!

谁知到了晚上八点多,我发现宝宝脸上开始出现一些小红疹子。到了九点多,疹子越来越多。我当时心里十分着急,赶忙抱起孩子开车到了医院。医生经过一番检查,确定孩子对蛋黄过敏。怎么会对鸡蛋过敏?当时我真不敢相信自己的耳朵。

原来,过敏指的是人体的一种过度反应,医学上叫变态反应。引起变态反应的物质称为过敏原。过敏反应至少包括四个方面的内容:过敏原、容易过敏的人、过敏反应过程和过敏反应的结果。过敏原可以是食物、药物、环境中的各种化学物质以及空气中的尘土等。过敏原是过敏性疾病的病因,去除过敏原患者便可以脱敏

看来我儿子的疹子就是过敏反应,那不用说,过敏原肯定就是鸡蛋了。可儿子怎么会对鸡蛋过敏呢?医生说目前还不清楚为什么处在同样环境下有些人发生过敏而多数人不发生反应,遗传因素肯定起了作用,但是局部环境因素同样重要。唉,儿子以后就不能吃鸡蛋了?我真为他感到难过。

Text (1): Allergic to eggs

I remember four months ago, I told my mother for the first time to give my son steamed eggs. That night, as soon as I came into the house from work, my mother excitedly said to me, “the baby is very strong today. one steamed egg, he can eat half of it!” I listened and was very happy, thinking I can add something to his meal every day in the future!

But at 8 pm, I noticed that the baby’s face began to show some red rashes. At nine o’clock, rashes were getting more and more. At that time, I was very worried and quickly picked up the child and drove to the hospital. The doctor checked to make sure the child was allergic to egg yolk. How can he have an allergy to eggs? I couldn’t believe my ears.

It turns out that allergy refers to an excessive reaction in the human body, which is called an allergic reaction in medicine. The substances that cause allergic reactions are called allergens. Anaphylaxis includes at least four aspects: allergen, allergic person, anaphylaxis process and anaphylaxis result. The allergen may be food, drugs, various chemicals in the environment, dust in the air, etc. Allergens are the cause of allergic diseases, and patients who remove allergens can desensitize.

It seems that my son’s rash is an allergic reaction, needless to say, the allergen must be eggs. But how can my son be allergic to eggs? Doctors say it is still unclear why some people develop allergies in the same environment while most people don’t respond. Genetic factors must play a role, but local environmental factors are also important. Alas, my son can’t eat eggs in the future? I feel so sorry for him.
