Figure 2.

Mean latencies (± SEM) of rats to balance on a beam before and after TBI with secondary hypoxemic insult. Before injury, rats were tested for their ability to balance for up to 60 seconds on a beam. Beginning 1 day after injury, beam-balance latencies were measured daily for 5 consecutive days. All injured groups had shorter latencies (indicating impairment) on day 1 after injury. Shown are saline (filled diamonds), AG (filled circles), and L-NIL (open triangles) treatments. *P < 0.05 vs. sham (open squares; shams were not subjected to CCI or hypoxemia). There were no differences between groups treated with iNOS inhibitors vs. saline after TBI.
