Osmotic nephrosis condition, or it may confused with other nephrotic conditions such as Tubular calcineurin-inhibitor toxicity. Affected cells of the proximal tubule may be passed in the urine, but a kidney biopsy is the only sure way to make a diagnosis. Responsible exogenous solutes include sucrose-containing IVIg, mannitol, dextran, contrast dye, and hydroxyethyl starch. Prevention includes standard preventions for iatrogenic kidney damage. Osmotic nephrosis is usually reversible but can lead to chronic renal failure. Osmotic nephrosis Osmotic nephrosis refers to structural changes that occur at the cellular level in the human kidney. Cells, primarily of the straight proximal tubule, swell due to
Wallerian degeneration effect is due to its presence in axonal and terminal compartments. The protection provided by the WldS protein is intrinsic to the neurons and not surrounding support cells, and is only locally protective of the axon, indicating an intracellular pathway is responsible for mediating Wallerian degeneration. The mutation causes no harm to the mouse. The only known effect is that the Wallerian degeneration is delayed by up to three weeks on average after injury of a nerve. At first, it was suspected that the "Wld" mutation slows down the macrophage infiltration, but recent studies suggest that the mutation protects axons
