1.比较了肉鸡慢抽动和快抽动尾部肌束膜和肌内膜的胶原纤维构筑。2.多克隆抗体免疫组织化学染色显示，I型和III型胶原在肌束膜和肌内膜均有分布。3.无肌纤维的肌内膜包被的细胞在颅部较大，这是因为存在较大的慢收缩肌纤维。内膜的蜂窝状结构被厚厚的周膜分成几部分。4.肌腱周胶原纤维粗大，纤维平行，由疏松的网状纤维和细小纤维相连，颅部比尾部更多、更厚。5.颅部较厚的肌内侧壁由略厚的胶原纤维组成，而尾部较薄的细胞侧壁较粗。6.这些结果表明，在肉鸡背阔肌中，慢抽动部分的肌周胶原纤维和肌内胶原纤维的生长均远大于快抽动的尾部。
1. Collagen fibre architectures of perimysium and endomysium in the slow-twitch cranial and fast-twitch caudal parts of broiler M. latissimus dorsi were compared. 2. Type I and III collagens were distributed in both perimysium and endomysium as indicated by their positive immunohistochemical reactions to polyclonal antibodies. 3. Cells invested by endomysium with no myofibres were larger in the cranial part because of the presence of larger slow-twitch myofibres. The honeycomb structure of endomysium was divided into several parts by thick perimysium. 4. The thick perimysial collagen fibres with parallel fibrils, which were interconnected by the loose reticular fibrils and thin fibres, were more numerous and thicker in the cranial part than the caudal. 5. Thick endomysial sidewall of cells in the cranial part was composed of a rougher reticulum of slightly thicker collagen fibrils compared with the thin sidewall in the caudal part. 6. These results indicated that both perimysial constitutions of collagen fibres and endomysial collagen fibrils had attained much larger growth in the slow-twitch cranial part than the fast-twitch caudal in broiler latissimus dorsi muscle.
