We performed the ultrastructural evaluation of presence and of some basic morphometric parameters of nemaline structures (NS) and Z band malformations in the musculus soleus fibres of rats kept in 7 months lasting immobilisation. Disturbances in Z band, leading to NS formation, were observed very often. Also numerous, classically rod-shaped NS were found in analyzed material. We demonstrate, for the first time in literature, that long-lasting hypokinesia induces NS formation. The pictures obtained may suggest successive steps in NS formation and maturation.

The sarcoplasmic reticulum Ca2+-ATPase (SERCA) isoforms are normally expressed in coordination with the corresponding myosin heavy chain (MyHC) isoforms in the fibers of skeletal muscle but this coordination is often disrupted in pathological conditions. In the streptozotocin-induced diabetes of rats (stz-rats), the soleus muscle showed peripheral neuropathy and the SERCA2a level decreased in type I (slow-oxidative) fibers compared to the control muscles, whereas the expression of the corresponding slow MyHC1 did not change. No difference was found at the mRNA and protein levels of SERCA and MyHC isoforms in the whole soleus, except that the level of the SERCA2a protein specifically declined in stz-rats compared to the controls. This shows that the coordinated expression of SERCA2a and MyHC1 is disrupted at the SERCA2a protein level in the diabetic soleus. The results are in line with previous observations that regulators of the Ca-homeostasis may adapt faster to type I diabetes than the contractile elements.
