  • The animals were from the MNU mammary carcinogenesis experiment described in Table 4 <$REFLINK> .

  • Results are expressed as mean ± SE (n = 8).

  • P < 0.05, compared with the corresponding control value.

  • P < 0.05, compared with the corresponding value from the Se-methylselenocysteine group.
