The cAMP content lowered in pituitary, but nor in testes; clear histological changes occurred in testicular tissue; Se-GSH-Px activity in both testis and adrenal gland lowered while LPO level significantly increased. Both Se-GSH-Px activity and LPO level in liver increased.These results indicate that MSG is harmful to the function of the hypothalamus-pituitarytarget system of neonatal rats展开更多
