Cerebral edema early stroke or hypoxia, cardiac arrest, and pseudotumor cerebri. During an ischemic stroke, a lack of oxygen and glucose leads to a breakdown of the sodium-calcium pumps on brain cell membranes, which in turn results in a massive buildup of sodium and calcium intracellularly. This causes a rapid uptake of water and subsequent swelling of the cells. It is this swelling of the individual cells of the brain that is seen as the main distinguishing characteristic of cytotoxic edema, as opposed to vasogenic edema, wherein the influx of fluid is typically seen in the interstitial space rather than within the
Tissue bank and tissue are acceptable organs for donation. A Willed Body Donation program is a program that allows people to donate their bodies after death. Most U.S. tissue bank companies get their supply of cadaver tissue through Willed Body Donation programs run by the tissue bank itself. These programs then charge their customers (mainly medical instrument companies) for services associated with preparation of the cadaver tissue ("e.g." transportation, refrigeration, and recovery) rather than charging money for the donated tissue itself, though it is not illegal to do so for non-transplant and or research organizations per the Uniform Anatomical Gift Act as
