近百年来,随着抗生素在临床上的广泛应用,一些致病菌产生抗药性的现象日趋严重。其结果是许多“王牌药”黯然失色,使抗生素的应用受到限制,给治疗上带来不少困难。此外,还容易罹患霉菌感染和其它疾病,使患者备受痛苦甚至危及生命。为了解决这一难题,科学家们经过辛勤努力,研制出了头孢菌素,为人类健康作出了新贡献。 In the past century, with the widespread use of antibiotics in clinical practice, some pathogenic bacteria become more and more drug-resistant. As a result, many “ace drugs” have been eclipsed, limiting the use of antibiotics and creating considerable difficulties in their treatment. In addition, it is also susceptible to mold infections and other illnesses that make patients suffering and even life-threatening. In order to solve this problem, scientists have worked hard to develop cephalosporins, made a new contribution to human health.
