Abstract: | The metabolism of trimethylselenonium ions (TMSe) was studied in male and female rats during maturation. Selenium (Se) retention
in the whole body as well as in organs was found to be significantly higher in male rats than in female a few hours after
parenteral administration of TMSe. The pronounced Se accumulation was observed in male kidneys. This sex-linked difference
was dependent on the presence of gonades and started to be manifested with sexual maturation during the third decade of postnatal
life. The effects of steroid hormones on the retention of Se from TMSe were examined in female and castrated male rats. The
results indicate that TMSe metabolism in rat kidneys may be influenced by androgen steroids. |
