In the sublethal model, AKBR decreased transiently (p &lt; 0.01) and superoxide production by isolated liver macrophages increased significantly after opsonized zymosan (OZ) stimulation (p &lt; 0.05). On the other hand, in the lethal model, AKBR decreased markedly (p &lt; 0.01) to below 0.4 without recovery, and superoxide production was not activated by OZ stimulation. Thus, when AKBR decreases to an irreversible level, below about 0.4, superoxide production by liver macrophages is impaired, while as long as AKBR remains reversible, more than about 0.4, it is enhanced. It is suggested that superoxide production by the Kupffer cells is related to the intrahepatic oxidation-reduction state in the septic model.<\/jats:p>","DOI":"10.1159\/000129229","type":"journal-article","created":{"date-parts":[[2008,4,28]],"date-time":"2008-04-28T02:35:14Z","timestamp":1209350114000},"page":"363-371","source":"Crossref","is-referenced-by-count":8,"title":["Superoxide Production by Liver Macrophages in a Septic Rat Model \u2013 Relation to Arterial Ketone Body Ratio"],"prefix":"10.1159","volume":"24","author":[{"given":"Y.","family":"Iimuro","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Yamamoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Inoue","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Kohno","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.","family":"Matsumoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2008,4,23]]},"container-title":["European Surgical Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000129229","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T12:06:02Z","timestamp":1777550762000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000129229"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008,4,23]]},"references-count":0,"journal-issue":{"issue":"6","published-online":{"date-parts":[[1992,6,1]]},"published-print":{"date-parts":[[1992,6,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000129229","archive":["Portico"],"relation":{},"ISSN":["0014-312X","1421-9921"],"issn-type":[{"value":"0014-312X","type":"print"},{"value":"1421-9921","type":"electronic"}],"subject":[],"published":{"date-parts":[[2008,4,23]]}}}
