Abstract

After transferrin injection to the slow m. soleus of guinea pig no immunohistochemical changes in myosin composition with monoclonal antibodies (AB) against fast myosin heavy chain (HCf) have been found. All muscles fibers in intact and experimental animals were identified as slow ones (type I of muscle fibers). After colchicine treatment of nerve trunk innervating slow muscle, some muscle fibers reacting with monoclonal AB against myosin HCf have been found. However, after colchicine treatment of nerve trunk and transferrin injection also some muscle fibers in slow muscle reacting with monoclonal AB against myosin HCf have been found. In appears that transferrin probably can not be the factor of neurotrophic control for myosin composition in skeletal muscle.

Abstract

The immunohistochemical profile of intact and denervated soleus muscle of guinea pigs after sensibilization was studied. It is shown, that intact soleus muscle consists of slow fibers, which have low ATP-ase activity and don't react with monoclonal antibodies against fast myosin heavy chain. No changes of immunohistochemical profile were found after denervation or sensibilization. At the same time, the fibers, reacting with monoclonal antibodies against fast myosin heavy chain and having low ATP-ase activity, were found in denervated muscles after sensibilization. It is concluded, that the synthesis of fast myosin is induced after sensibilization of denervated muscles. Validity of myosin ATP-ase histochemistry for muscle fibers typing is discussed.

Abstract

After experimental cease of neurotrophic control of skeletal muscle by denervation no changes in myosin ATP-ase histochemistry and immunohistochemical profile in slow (m. soleus) muscle of guinea pig were found. All muscle fibers in intact muscle fibers). However after colchicine blockade of axoplasmic transport in this slow muscle some muscle fibers reacting with monoclonal antibodies against fast myosin heavy chain were found. At the same time no changes in histochemical ATP-ase profile were observed. Validity of myosin ATP-ase histochemistry for muscle fibers typing as well as possible influence of nerve activity and neurotrophic control itself were discussed.

Abstract

Myosin ATPase and succinic dehydrogenase activity and fast myosin (indirect immunochemical test) were assayed in m. soleus of guinea-pigs after the administration of T4 (200 micrograms/kg) to animals every day for 3 weeks. This was followed by the application of 10 mM colchicine solution to sciatic nerve for 6 min. Fast muscle fibers and the line of precipitation with antiserum to fast myosin were revealed in soleus muscle of experimental animals after the application of colchicine and T4 injection.
