摘要

本研究旨在描述割草机(Thryonomys swinderianus, Temminck 1827)大腿肌肉中的纤维成分。本研究使用了 10 只 4 至 6 个月大(3 至 4 千克)的雄性割草机。大腿的 11 块骨骼肌[股二头肌 (BF)、股直肌 (RF)、股外侧肌 (VL)、股内侧肌 (VM)、股筋膜张力肌 (TFL)、半腱肌 (ST)、半膜肌 (ST)半膜肌(SM)、半膜肌接入肌(SMA)、萨尔托里肌(SRT)、栉水母肌(PCT)、内收肌(AM)]在动物安乐死后采集,并用光学显微镜进行观察。利用酶组织化学技术[肌苷腺苷三磷酸酶(ATPase)和烟酰胺腺嘌呤二核苷酸四唑还原酶(NADH-TR)]在这些肌肉中发现了三种肌纤维类型(I、IIB 和 IIA)。在这 11 块肌肉中,有 10 块肌肉由 89% 至 100% 的快速收缩纤维(IIA 型和 IIB 型)组成,而 SMA 几乎完全由慢收缩纤维组成。

Fiber Composition of the Grasscutter (<i>Thryonomys swinderianus</i>, Temminck 1827) Thigh Muscle: An Enzyme-histochemical Study.

Fiber Composition of the Grasscutter (Thryonomys swinderianus, Temminck 1827) Thigh Muscle: An Enzyme-histochemical Study.

The aim of this study was to describe de fiber composition in the thigh muscles of grass cutter (Thryonomys swinderianus, Temminck 1827). Ten 4 to 6-month-old (3 to 4 kg) male grasscutter were used in this study. Eleven skeletal muscles of the thigh [M. biceps femoris (BF), M. rectus femoris (RF), M. vastus lateralis (VL), M. vastus medialis (VM), M. tensor fasciae latae (TFL), M. semitendinosus (ST), M. semimembranosus (SM), M. semimembranosus accessorius (SMA), M. Sartorius (SRT), M. pectineus (PCT), M. adductor magnus (AM)] were collected after animals euthanasia and examined by light microscopy. Three muscle fiber types (I, IIB and IIA) were found in these muscles using enzyme histochemical techniques [myosine adenosine triphosphatase (ATPase) and nicotinamide adenine dinucleotide tetrazolium reductase (NADH-TR)]. Ten of these eleven muscles are composed by 89% to 100% of fast contracting fibers (types IIA and IIB), while the SMA was almost exclusively formed by slow contracting fibers.
