Copaiba Oil-Resin Treatment Is Neuroprotective and Reduces Neutrophil Recruitment and Microglia Activation after Motor Cortex Excitotoxic Injury

Figure 1

COR treatment effects on gross histopathology at 1 day following NMDA injection into the rat motor cortex, as revealed by cresyl violet staining. Animals treated with 5% tween (a-b) or 400 mg/kg of COR (c-d). COR treatment reduced polymorphonuclear cell infiltration and tissue loss (c-d) compared to vehicle animals (a-b). Arrows point to polymorphonuclear cells (d). Asterisks indicate the excitotoxic necrotic center. Scale bars: (a–c) (300 μm); (b–d) (50 μm).
