In this study we analysed the changes in the properties of rat cerebral cortex Na+K(+)-ATPase in streptozotocin induced diabetes (STZ-diabetes). Special attempt was made to determine whether insulin treatment of diabetic animals could restore the altered parameters of this enzyme. Na+/K(+)-ATPase activity was found to be decreased by 15% after 2 weeks, and(More)
The sarcoplasmic reticulum Ca(2+)-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(More)
AIMS/HYPOTHESIS Diabetes mellitus has a serious effect on most of the properties of skeletal muscles. Changes in neuromuscular transmission are also involved in propagating the disease. METHODS In our experiments, acetylcholinesterase was extracted from the fast extensor digitorum longus and slow soleus muscles of control, non-treated 6-week-diabetic and(More)
The activity of acetylcholinesterase molecular forms were examined after separation on sucrose gradients during notexin-induced necrosis and the following regeneration in rat extensor digitorum longus (EDL) and soleus (SOL) muscles. All forms dropped rapidly in both muscles in the first few days after single notexin injection. After a delay small globular(More)
