Figure 8From: Prostanoid receptor EP1 and Cox-2 in injured human nerves and a rat model of nerve injury: a time-course study Cox-2 and OX42 immunoreactive cells in sham and CCI rat nerve at 4 days post operation. Very few Cox-2 immunoreactive cells (arrowheads) were observed in the left sciatic nerve of sham-operated (A) compared to CCI (B). Similarly, sham-operated nerves (C) showed much less macrophages in the sciatic nerve than CCI nerves (D). Scale bars = 50 μm.Back to article page
