The authors have shown that an anti-CD11d antibody treatment attenuates leukocyte infiltration and improves neurological function when administered beginning 2 hours after SCI. A more clinically relevant time for the initiation of treatment after SCI, however, is 6 or more hours postinjury.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>In Study 1, the T-4 vertebrae in four groups of rats were injured by a 50-g clip-induced compression method, and the anti-CD11d antibody (1 mg\/kg) was intravenously administered starting 2, 6, 12, or 24 hours postinjury. All groups received subsequent doses at 24 and 48 hours, and animals were killed at 72 hours. The anti-CD11d antibody treatment starting at 6 hours postinjury caused significant attenuation of leukocyte infiltration, reactive oxygen species\u2013associated enzymes, and secondary tissue damage. Based on these findings, Study 2 included two groups of rats receiving the aforementioned injury and treatment beginning at 6 hours postinjury (with subsequent treatments at 24 and 48 hours) with the anti-CD11d or a control antibody (1B7); these rats were then observed for 5 weeks. Basso-Beattie-Bresnahan (BBB) scores were significantly higher in anti-CD11d\u2013treated rats (mean BBB score 8.9 \u00b1 0.1) than controls (mean BBB score 7.7 \u00b1 0.1) 5 weeks postinjury. Increases in mean arterial pressure during colon distension were smaller in anti-CD11d\u2013treated rats (19.5 \u00b1 3.7 mm Hg) than in controls (37.4 \u00b1 4.7 mm Hg).<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>These findings suggest that antiinflammatory treatments that reduce secondary tissue damage after SCI may be delayed until 6 hours postinjury and still be effective.<\/jats:p><\/jats:sec>","DOI":"10.3171\/spi.2006.5.4.343","type":"journal-article","created":{"date-parts":[[2008,1,24]],"date-time":"2008-01-24T13:12:52Z","timestamp":1201180372000},"page":"343-352","source":"Crossref","is-referenced-by-count":37,"title":["A
