    Daim ntawv thov

    1. Hormone postulated los kho cov photoperiodicity nyob rau hauv cov tsiaj. Inhibits cerebellar nitric oxide synthetase

    2. Melatonine tuaj yeem siv rau hauv kev pw tsaug zog induction, hloov kho circadian atherosclerosis, antioxidant, dawb radical scavenger

    3. Immunostimulant; Melatonin receptor ligand

    4. Melatonin muaj kev cuam tshuam rau txoj hauv kev apoptotic, inhibiting apoptosis hauv lub cev tiv thaiv kab mob thiab neurons tab sis txhim kho apoptotic cell tuag ntawm cov qog nqaij hlav cancer. Inhibits proliferation / metastasis ntawm cov qog nqaij hlav cancer ntawm lub mis los ntawm inhibiting estrogen receptor action.
