Isingeniso
I-Oxytocin, iyi-hormone ye-peptide kanye ne-neuropeptide, uhlobo lomuthi we-uterine contractile, ongakhishwa ku-pituitary yangemuva yezilwane noma wenziwe ngamakhemikhali.Uma kuhlanganiswa ngamakhemikhali angenayo i-vasopressin futhi engenawo umphumela wengcindezi.
Ingakwazi ukukhetha ngokukhetha umsipha obushelelezi wesibeletho futhi iqinise ukufinyela kwayo.Isibeletho se-parturient sizwela kakhulu i-oxytocin ngenxa yokwanda kokukhiqizwa kwe-estrogen.Isibeletho esingavuthiwe asinakusabela kulo mkhiqizo.Ukusabela kwesibeletho ku-oxytocin kwakuphansi ekuqaleni kwe-trimester yokuqala noma emaphakathi yokukhulelwa, kodwa kwanda kancane kancane ngasekupheleni kwe-trimester yokukhulelwa, futhi kwafinyelela okuphezulu kakhulu ngaphambi kokusikwa.
Umthamo omncane ungaqinisa ukufinyela okunesigqi kwemisipha ebushelelezi ezansi kwesibeletho, uqinise ukufinyela kwawo, usheshise imvamisa yokufinyela, futhi ulondoloze i-polarity nokulinganisa okufana nokuletha kwemvelo.Ngakho-ke, isetshenziselwa ukwelapha ukunxenxa abasebenzi noma i-oxytocia.
Umthamo omkhulu wenza imisipha yesibeletho ifinyele ngendlela ye-tetanic.Isetshenziswa emtholampilo ukucindezela imithambo yegazi phakathi kwemicu yemisipha, ukuvimbela ukopha kwangemva kokubeletha kanye nokungaphelele kwangemva kokubeletha.Ikhuthaza ukuncelisa, inciphisa umgudu webele, futhi ikhuthaze ukuphuma kobisi ebeleni.Kodwa-ke, ayikwazi ukwandisa ukukhishwa kobisi, kodwa ingakhuthaza kuphela ukukhishwa kobisi.
I-Oxytocin ivame ukuhlanganiswa nokulungiswa kwe-ergot ukwelapha ukopha kwangemva kokubeletha.Isetshenziselwa ikakhulukazi ukubeletha okubangelwa ukukhulelwa sekwephuzile kanye nokubeletha okubambezelekile okubangelwa i-atony yesibeletho ngesikhathi sokubeletha.Iphinde isetshenziselwe ukuhlola ukuzwela kwe-oxytocin kanye nokusiza ekukhipheni ubisi lwangemva kokubeletha.
I-Oxytocin ikhishelwa egazini njengehomoni ekuphenduleni umsebenzi wocansi kanye nangesikhathi sokubeletha.Iyatholakala futhi ngefomu lezemithi.Kunoma yiluphi uhlobo, i-oxytocin ivuselela ukufinyela kwesibeletho ukuze kusheshiswe inqubo yokubeletha.Ukukhiqizwa nokukhishwa kwe-oxytocin kulawulwa indlela yokuphendula eyakhayo, lapho ukukhululwa kwayo kokuqala kukhuthaza ukukhiqizwa nokukhululwa kwe-oxytocin eyengeziwe.
