The study of Na+, K(+)-ATPase activity of rat brain during Crush syndrome.
Crush syndrome (CS) results from severe traumatic damage to the organism that is characterized by stress, acute homeostatic failure of the tissues, and myoglobinuria with severe intoxication. This leads to an acute impairment of kidneys and heart. The peripheral and central nervous systems are also the subject of significant changes in CS. Na(+), K(+)-ATPase is a critical enzyme in neuron that is essential for the regulation of neuronal membrane potential, cell volume as well as transmembrane fluxes of Ca(++) and Excitatory Amino Acids. In the present study, Na(+), K(+)-ATPase activity of rat brain regions [Olfactory lobes (OL), Cerebral cortex (CC), Cerebellum (CL), and Medulla oblongata (MO)] during CS was investigated. Experimental model of CS in albino rats was induced by 2-h of compression followed by 2, 24, and 48-h of decompression of femoral muscle tissue. In this study, we have observed elevation in Na(+), K(+)-ATPase activity above normal/control levels in all parts of brain (OL: 34.4%; CC: 1.0%; CL: 3.3% and MO: 45%) during 2-h compression in comparison to controls.
