抗菌素是用粮食生产的。现在生产1吨四环素、青霉素和链霉素需要20吨粮食,而生产出1吨卡那霉素和庆大霉素就需100吨粮食。可见,节约抗菌素就是节约粮食,是响应毛主席关于“广积粮”伟大号召的大事情。从医疗和预防的观点来说,合理应用抗菌素,可避免或减少一些不必要的麻烦,如毒性反应、过敏反应、耐药性、二重感染等。因此,我们必须重视抗菌素类药物的合理应用。下面谈谈抗菌素应用中的几个问题。 Antibiotics are made from food. It now takes 20 tons of food to produce 1 ton of tetracycline, penicillin and streptomycin, and 100 tons of food are required to produce 1 ton of kanamycin and gentamicin. It can be seen that saving antibiotics is saving food and responding to Chairman Mao’s great event on the great call for “wide food rationing”. From a medical and preventive standpoint, rational use of antibiotics can avoid or reduce some unnecessary troubles such as toxic reactions, allergic reactions, drug resistance, double infection and so on. Therefore, we must attach importance to the rational use of antibiotics. Below to talk about several issues in the application of antibiotics.
