Sunflower seed oil and N-acetylcysteine (NAC) moderated the effects of prenatal stress on multivacuolated microglia. a Oil reduced total microglia density and the density of amoeboid and ramified microglia compared to saline. Oil with prenatal stress (PS oil) reduced prenatal stress-induced levels (solid line) of multivacuolated microglia. b Concomitant NAC with prenatal stress (PS/NAC) resulted in no difference in microglia density for any subtype compared to NS/NAC, but reduced prenatal stress-induced levels (solid line) of multivacuolated microglia. (*p < 0.05 and **p < 0.01 compared to saline or NS/NAC). Previous findings on microglia density indicated by dotted line for non-stress (NS) and solid line for prenatal stress (PS) levels, [13].(^†p < 0.05 compared to PS)
