sPLA2 protein expression following SCI. A) Representative western blots from sham or contused animals at 15 min, 4 hr, 1 day, or 1 wk post injury. The top panel in A shows time course of sPLA2-IB (16 & 14 kDa) showing no changes following SCI. SCI induced significant increase in sPLA2-IIA (15 kDa) and IIE (18 kDa) beginning at 4 hr and 1 day post injury, but returning to baseline by 1 week. Group X (13 kDa) showed no change in expression. Note lane 6 in IIA blot is equal amount of splenic protein for control. B - E) Quantification of western blots in A (n = 4/group, mean ± SD). (**p < 0.01 versus sham)
