Previous studies have shown that the Na-K-Cl cotransporter of cerebral microvascular endothelial cells and astrocytes is a major participant in ischemia-induced cerebral edema in stroke. The present study was conducted to test the hypothesis that the Na-K-Cl cotransporter also contributes to cerebral edema in DKA. Sprague-Dawley rats were administered streptozotocin to induce DKA, and then cerebral edema was assessed by determination of apparent diffusion coefficients (ADC) with magnetic resonance diffusion-weighted imaging. Cerebral ADC values in DKA rats were significantly reduced in both cortex and striatum compared with non-DKA control rats, indicating the presence of cerebral edema. Intravenous administration of bumetanide to DKA rats abolished the drop in cortical ADC values, while having no significant effect in the striatum. Insulin and saline treatment had no effect when given after bumetanide but increased both cortical and striatal ADC values when given before bumetanide. Evidence is also presented here that acetoacetate and \u03b2-hydroxybutyrate stimulate brain microvascular Na-K-Cl cotransporter activity. These findings suggest that the Na-K-Cl cotransporter contributes to brain edema in DKA.<\/jats:p>","DOI":"10.2337\/diabetes.54.2.510","type":"journal-article","created":{"date-parts":[[2007,3,6]],"date-time":"2007-03-06T19:04:22Z","timestamp":1173207862000},"page":"510-516","update-policy":"https:\/\/doi.org\/10.2337\/ada-journal-policies","source":"Crossref","is-referenced-by-count":60,"title":["Bumetanide Reduces Cerebral Edema Formation in Rats With Diabetic Ketoacidosis"],"prefix":"10.2337","volume":"54","author":[{"given":"Tina I.","family":"Lam","sequence":"first","affiliation":[{"name":"Department of Physiology and Membrane Biology, University of California, Davis, California"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Steven E.","family":"Anderson","sequence":"additional","affiliation":[{"name":"Department of Physiology and Membrane Biology, University of California, Davis, California"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicole","family":"Glaser","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University of California, Davis, California"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Martha E.","family":"O\u2019Donnell","sequence":"additional","affiliation":[{"name":"Department of Physiology and Membrane Biology, University of California, Davis, California"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1167","reference":[{"key":"2022031208410350800_R1","doi-asserted-by":"crossref","unstructured":"Edge JA: Cerebral oedema during treatment of diabetic ketoacidosis: are we any nearer finding a cause?Diabetes Metab Res Rev\u200816:316\u2013324,2000","DOI":"10.1002\/1520-7560(2000)9999:9999<::AID-DMRR143>3.0.CO;2-R"},{"key":"2022031208410350800_R2","doi-asserted-by":"crossref","unstructured":"Glaser N, Barnett P, McCaslin I, Nelson D, Trainor J, Louie J, Kaufman F, Quayle K, Roback M, Malley R, Kupperman N: Risk factors for cerebral edema in children with diabetic ketoacidosis.
