Only one isozyme of hexokinase (type I) was found in a soluble fraction of smooth muscle of rabbit stomach using column chromatography and polyacrylamide gel electrophoresis. By the pattern of metabolism the smooth muscle of rabbit stomach accupies an intermediate position between rapidly and slowly contracting sceletal muscles, approaching to musculus soleus by the activity and isozyme spectra of hexokinase and lactate dehydrogenase (LDH). Activity of these enzymes was altered not uniformly in dissimilarly functioning muscles of rabbits with experimental allergic encephalomyelitis: it was increased in musculus gastrocnemius of rabbits and decreased in soleus or in smooth muscles. LDH isoenzyme spectra changed towards an increase in aerobic H-subunits and decrease in anaerobic M-subunits in the soluble fraction of musculus gastrocnemius of rabbits with experimental allergic encephalomyelitis. Content of LDH-5 and LDH-4 was about 2-fold increased and content of LDH-1 and LDH-2 was decreased in musculus soleus.

Nitrosative stress has been implicated in the pathophysiology of several CNS disorders, including multiple sclerosis (MS) and its animal model experimental autoimmune encephalomyelitis (EAE). We have recently shown that protein nitrosothiols (PrSNOs) accumulate in the brain of MS patients, and there is indirect evidence that PrSNO levels are also increased in EAE. In this study we sought to identify the major PrSNOs in the spinal cord of EAE animals prepared by active immunization of C57/BL6 mice with MOG(35-55) peptide. For this purpose, PrSNOs from control and EAE mice at various disease stages were derivatized with HPDP-biotin, and the biotinylated proteins were isolated with streptavidin-agarose. Proteins from total and streptavidin-bound fractions were then analyzed by Western blotting using antibodies against the major S-nitrosylated substrates of CNS tissue. With this approach we found that the proportion of S-nitrosylated neurofilament proteins, NMDA receptors, alpha/beta-tubulin, beta-actin, and GAPDH is increased in EAE. Other potential substrates either were not S-nitrosylated in vivo (HCN3, HSP-72, CRMP-2, gamma-actin, calbindin) or their S-nitrosylation levels were unaltered in EAE (Na/K ATPase, hexokinase, glycogen phosphorylase). We also discovered that neuronal specific enolase is the major S-nitrosylated protein in acute EAE. Given that S-nitrosylation affects protein function, it is likely that the observed changes are significant to the pathophysiology of inflammatory demyelination.

1. Brain homogenates of mice infected with the Theiler FA strain of mouse encephalomyelitis virus show marked inhibition of glucose phosphorylation. 2. A similar effect can be obtained by incubating normal brain homogenates with small amounts of ferrous sulfate. 3. Partially purified preparations of Theiler FA virus contain iron in amounts corresponding to their inhibitory effect on brain glycolysis. The virus preparations were purified by chemical fractionation and differential centrifugation and were dialyzed against potassium cyanide or pyrophosphate and potassium chloride for several days before they were analyzed for iron content. 4. The inhibitory effect of the virus preparations and of ferrous sulfate has been shown to be dependent on a heat-labile factor present in normal brain ("inactivating factor"). 5. The glycolytic activity of brain homogenates of mice infected with the Theiler FA virus can be restored by addition of a factor prepared from rabbit muscle extract. This "restoring factor" is non-dialyzable and is heat-labile. It has no hexokinase or phosphohexokinase activity. Its restoring activity is destroyed by the "inactivating factor" present in brain.
