Ulwazi Oluyisisekelo
I-Melatoniniyi-hormone ekhiqizwa i-pineal gland, futhi isakhiwo sayo samakhemikhali sasiyi-5-methoxy-N-acetyl tryptamine, umsebenzi we-physiological wokuvimbela i-gonad, i-thyroid, i-adrenal gland, i-parathyroid gland kanye nomsebenzi we-pituitary, ukuvimbela ukuthomba ngaphambi kwesikhathi, ukunciphisa ukukhishwa kwe-pituitary Melanotropin;futhi inomsebenzi wesimiso sezinzwa esimaphakathi, ingathuthukisa ukudlikizela umbundu, ibangele ukozela.Lapho i-pinealectomy ngemva kokuhlolwa kwezilwane ikhombisa i-hyperplasia yezindlala, ukwanda kwesisindo, ikakhulukazi ubulili nezitho zobulili zamagundane angavuthiwe kusenesikhathi, ukukhiqizwa kwe-pituitary ye-LH ne-FSH kwanda, okwandisa ukukhishwa kwe-thyroid kanye ne-adrenal cortex hormone melatonin.I-MSH ye-pituitary encishisiwe kakhulu futhi yenza isikhumba sale ndima sibe mhlophe.Imiphumela ohlelweni lwezinzwa olumaphakathi, ku-EEG yomuntu yabonisa isigqi esinensayo, ukwanda kokubanjwa, ukozela, kodwa akuphazamisi ukuziphatha kwabo nobuntu, yesithuthwane se-lobe yesikhashana kanye nesifo se-Ba Jinsen kunganciphisa i-motor nerve Izinguquko ezingavamile ze-EEG.
Ukusetshenziswa
1. I-Melatonin ingasetshenziswa njengemikhiqizo yokunakekelwa kwezempilo, ukuze kuthuthukiswe ukusebenza kwamasosha omzimba, kuvimbele ukuguga nokubuyela ebusheni.Ngaphezu kwalokho, liphinde libe uhlobo “lwephilisi lokulala” lemvelo.

3. Ucwaningo lwamakhemikhali ezinto eziphilayo.
4. I-hormone postulated ukulamula photoperiodicity ezilwaneni ezincelisayo.Ivimbela i-cerebellar nitric oxide synthetase
5. I-Melatonine ingasetshenziswa ekwenziweni kokulala, iguqula isigqi se-circadian, i-antioxidant, i-free radical scavenger
