叮咚，叮咚，门铃响了，在医院工作的妈妈劳累一天回家了，我立刻把椅子拿来，关心的端一杯水给妈妈。让妈妈疲惫的身体放松一下。并关切的问：为什么现在患者这么多呀？妈妈说：“现在人们生活水平提高了，节奏快，当然希望病早点好呀！所以有一点小病都要吃药输液”。“是呀！药物注射进去病就好了，而且越贵的见效就越快。”我马上回答。妈妈摇摇头说：“其实这都是人们的误解。病情发展是有一定的发展周期，当身体在与疾病做斗争的过程中，身体的免疫力大大增强，只要注意休息一般都可以自愈的。也许时间会长些。但是人们为了尽快战胜细菌，就用抗生素来参战。虽说胜利了。岂不知细菌也是生命体，在抵抗抗生素的杀灭作用时，会产生耐药性。在不合理使用抗生素的情况下，抗生素频繁刺激细菌，使细菌迅速耐药，甚至任何一种耐药菌都有可能发展成为超级耐药菌。长此下去，抗生素越来越失效，很多感染性疾病将无药可治。 而且在使用抗生素时也杀掉了一些有益的菌群”。 我恍然大悟，怪不得我一生病妈妈都不给我挂盐水，我还以为妈妈舍不得给我挂盐水呢。妈妈还说：北京的一家知名医院曾经救治过一位年轻的患者，尽管医生竭尽全力为这位患者试用了多种类型的抗生素，都遏制不了病情的发展，即便药效最强的万古霉素抗生素，对这个患者也没有效果，患者最终死亡了。在死者家属的同意下，专家们对尸体进行了医学解剖研究，然而检查结果却出人意料！尸体解剖发现，他的体内存在着大量的耐药菌的感染，而且这些耐药菌对目前使用的这些抗生素是没效的！更令人意外的是，这种能耐多种抗生素的细菌竟然是死者自己买抗生素吃出来的。原来，死者每天都在单位食堂吃饭，由于顾虑单位食堂不干净，所以他每次吃完饭后都要吃两粒抗生素。天天吃，所以日积月累，最后就出了问题。 医学界流传着一句话：“美国枪支容易买得到，抗生素很难买得到，而中国恰好相反。”用这句话来形容抗生素的重要性和在中国的滥用程度再恰当不过了！ 一句话,为了我们人类自身，我要大声呼吁,合理应用抗生素吧.！让大家从我做起，还原绿色的社会,绿色的环境,！让你我更
