Description:
Veratridine-stimulated uptake of sodium-22 in brain synaptosomes was significantly reduced by ionizing radiation over a dose range of 10 to 1000 rads. The response was dose-dependent and involved a decrease in the maximum effect of veratridine on uptake. The central nervous system may be more sensitive to ionizing radiation than generally thought, perhaps through a loss of the ability of the sodium channel to respond properly to stimulation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wixon, H N -- Hunt, W A -- New York, N.Y. -- Science. 1983 Jun 3;220(4601):1073-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6302846" target="_blank"〉PubMed〈/a〉
