SOD2 and congenital rubella syndrome: The animals exposed to CRS treated with lithium showed decreased levels of SOD2 mRNA by 16% (p < 0.05, t-test, Figure 6(b)) and protein by 14% (p < 0.05, t-test, Figure 6(b)) and the enzyme activity by 37% (p < 0.001, t-test, Figure 5(b)) compared with CRS animals.
