WebCerebrospinal fluid (CSF) and brain tissue sodium levels increase during migraine. However, little is known regarding the underlying mechanisms of sodium homeostasis disturbance in the brain during the onset and propagation of migraine. Exploring the cause of sodium dysregulation in the brain is important, since correction of the altered sodium … WebThe osmolarity of the four preparations was within the physiologic range of CSF for 7 days at both 2-8℃ and 25℃. The pH values close to the physiologic range of CSF were stable … up dress monkey bars
