Figure 1From: Prostanoid receptor EP1 and Cox-2 in injured human nerves and a rat model of nerve injury: a time-course study EP1 immunoreactivity in human injured brachial plexus nerves and avulsed DRG. EP1-IR was observed in nerve fibres in control nerves (A) and appeared more intense in injured nerves (B). EP1-IR was detected mainly in some small/medium diameter neurones (arrowheads) of control (C) and more so in injured human DRG (D). Scale bars = 50 μm.Back to article page
