Table 3: p-values of pair wise comparisons. Values of gene expression of liver are reported above the diagonal. The corresponding values for testis are reported below the diagonal. The set of four values correspond to the expression of Gpx1, SOD, FMO2 and GAPDH, respectively. C7: animals instilled with control solution and sacrificed at day 7; NP7: animals instilled with NP suspension and sacrificed at day 7; Ag7: animals instilled with AgNO3 solution and sacrificed at day 7; C28: animals instilled with control solution sacrificed at day 28, NP28: animals instilled with NP suspension and sacrificed at day 28; Ag28: animals instilled with AgNO3 solution and sacrificed at day 28. (p-value <0.05; p-value <0.01).
