段落翻译一A mother in the US is eager to find bone marrow donors

在美国的一位母亲正急于找寻骨髓捐赠者来挽救她三个女儿的性命,她们都患上一种罕有的血液紊乱症.现在,她正与联邦法例周旋,因法例禁止她向准捐赠者付钱.
fighting against the law 的意思是打官司,不单止是反对,故翻作“与联邦法例周旋”.
原文如下：
A mother in the US is eager to find bone marrow donors to save the lives of her three daughters who are suffering from a rare blood disorder.Now,she's fighting against a federal law stopping her from paying future donors.
