摘要
High blood ammonia, as seen in severe liver disease and urea cycle disorders, is neurotoxic and difficult to treat. A new study shows that the toxic effects are caused by impaired astrocyte potassium buffering—not astrocyte swelling, as previously thought—and can be partially blocked by the diuretic bumetanide (pages 1643–1648). © 2013 Nature America, Inc.
