IL1B and congenital rubella syndrome: However, compared with the CRS group, FG administrated at 1 g/kg significantly inhibited the increases of TNF-α (F4,34 = 0.488, p < 0.05), FG (0.5 and 1 g/kg) and DNP markedly diminished the level of IL-1β (F4,35 = 0.150, F4,35 = 2.986, F4,35 = 0.437, p < 0.01, p < 0.001 and p < 0.05).
