The fibre density of the extensor digitorum communis muscle was examined with a monopolar single fiber electrode in 2 definite, one probable and 15 possible Duchenne-carriers. In addition serum-CK was evaluated three times in intervals of a least one week. The fibre density was increased in one definite, one probable and 4 possible carriers (greater than 1.6). The highest value was 2.0. Excepting one case the increase of fibre density was accompanied by an increase of serum-CK (greater than 60 mg%). The highest value of CK was 1626 mg%. The conventional EMG was pathological in 2 cases. In no case with an increase of CK or with pathological EMG the fibre density was normal. The fibre density is an unspecific but rather sensible indicator of Duchenne-carriers but as we could observe in a definite carrier, negative results do not exclude carriers.
使用单极单纤维电极对2例确诊、1例疑似和15例可能的杜兴氏携带者的指总伸肌纤维密度进行了检测。此外，每隔至少一周对血清肌酸激酶（CK）进行三次评估。1例确诊、1例疑似和4例可能的携带者的纤维密度增加（大于1.6）。最高值为2.0。除1例外，纤维密度增加的同时血清CK也升高（大于60mg%）。CK的最高值为1626mg%。2例患者的常规肌电图检查结果异常。在CK升高或肌电图检查结果异常的病例中，纤维密度均未正常。纤维密度是杜兴氏携带者的一个非特异性但相当敏感的指标，但正如我们在1例确诊携带者中观察到的，阴性结果并不能排除携带者。
