目前,对肌营养不良症是一种“原发肌肉变性疾病”的传统概念,已有怀疑,认为实际上可能为神经性。作者等采用神经和肌肉联合培养的方法研究本病的发病原理。实验分四组:正常神经/正常肌肉(10),正常神经/“营养不良”肌肉(21),“营养不良”神经/正常肌肉(6),“营养不良”神经/“营养不良”肌肉(7)。标本取自正常鼠和同型合子的肌营养不良鼠。神经组织为14～15天胎鼠的含有一对神经节的脊髓横切 At present, muscular dystrophy is a traditional concept of “primary muscle degenerative disease”, which has been suspected and may actually be neuropathic. The authors studied the pathogenesis of this disease using a combination of nerve and muscle culture methods. The experiment was divided into four groups: Normal Nerve / Normal Muscle (10), Normal Nerve / “Malnourished” Muscle (21), “Malnourished” Nerve / Normal Muscle (6), “Malnourished” Nerve / 7). Specimens were taken from dystrophic rats of normal mice and homozygotes. Nerve tissue is 14 to 15 days of fetal rat spinal cord containing a pair of transverse
