In this study we have examined the correlation between pDNA and these blood parameters in health and stroke. Acid\u2013base equilibrium, oxygen status, hemoglobin affinity to oxygen and concentration of pDNA in arterial blood were measured after the intravenous injection of homologous long\u2010chain DNA to healthy rats and rats subjected to common carotid arterial occlusion. In addition the effect of adding homologous DNA to human and rat venous blood samples was studied <jats:italic>in vitro<\/jats:italic>. Hyperoxia, alkalemia, and an increase in hemoglobin affinity to oxygen were seen in rats with artificial stroke. A marked decrease in pulmonary hyperventilation and hemoglobin affinity to oxygen was observed after injection of homologous genomic DNA (10<jats:sup>\u22126<\/jats:sup> g\/mL of blood). After the DNA injection, blood gas measurement and concentration of pDNA were correlated. Addition of DNA at a concentration of 10<jats:sup>\u22127<\/jats:sup> g\/mL to venous blood samples <jats:italic>in vitro<\/jats:italic> increased oxygen saturation that disappeared when the dose of the DNA increased 10\u2010fold. Thus, a change of pDNA concentration or size can alter acid\u2013base equilibrium, oxygen status, and oxygen transport. These results may be important for a better understanding of the mechanisms of stroke and other diseases associated with the elevation of pDNA concentration, and they open the possibility of new therapeutic approaches.<\/jats:p>","DOI":"10.1196\/annals.1448.040","type":"journal-article","created":{"date-parts":[[2009,8,11]],"date-time":"2009-08-11T11:29:58Z","timestamp":1249990198000},"page":"278-282","source":"Crossref","is-referenced-by-count":0,"title":["Influence of Plasma DNA on Acid\u2013Base Balance, Blood Gas Measurement, and Oxygen Transport in Health and Stroke"],"prefix":"10.1196","volume":"1137","author":[{"given":"Irina L.","family":"Konorova","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natalya N.","family":"Veiko","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Viktor E.","family":"Novikov","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2008,9,16]]},"reference":[{"key":"e_1_2_5_2_2","first-page":"2","article-title":"Analysis of 16S rRNA gene sequences and circulating cell\u2010free DNA from plasma of chronic fatigue syndrome and non\u2010fatigued subjects","volume":"23","author":"Vernon S.D.","year":"2002","journal-title":"BMC Microbiol."},{"key":"e_1_2_5_3_2","first-page":"135","volume-title":"Proceedings of the First International Congress on Rheology","author":"Toms B.A.","year":"1948"},{"key":"e_1_2_5_4_2","doi-asserted-by":"publisher","DOI":"10.1038\/211170a0"},{"key":"e_1_2_5_5_2","first-page":"16","article-title":"Hemodynamic effect of plasma DNA","volume":"5","author":"Gannushkina I.V.","year":"1998","journal-title":"Vestn.
