On the contrary, oral administration of flaxseed oil cultivars (G9 or G10) at a dose of 270 mg/kg b.wt for 2 weeks to rats with PPD induced by HSP significantly restored the hippocampal redox balance state and attenuated PPD-induced oxidative damage (Table 5). The gene discussed is HSP90B2P; the disease is progressive pseudorheumatoid arthropathy of childhood.
