Kutheni umzimba udinga i-oxytocin?
Ekuqaleni, nangaphambi kokuvavanywa kweekliniki ezininzi, i-oxytocin yayithathwa njenge-hormone kuphela kwabasetyhini abakhulelweyo. Yingakho wayeneli gama, kuba ekuguquleleni kolwimi lwesiGrike, i-oxytocin ithetha "ukuzalwa ngokukhawuleza".
Ngoko, ngexesha lophando lwe-British neuroscientist lifumene ukuba i-oxytocin inceda umfazi ekuzalweni. Yibangela ukunyakaza kwezivumelwano zeentlobo ze-uterine myometrium. Ngaphezu koko, uthatha inxaxheba ekuzaleni ubomi.
Nangona ngexesha lokuchumisa, ngokukhawuleza ngexesha lomzimba, inkosikazi egazini iphakamisa izinga le hormone, leyo leyo eyenza i-spermatozoa ifinyelele ngempumelelo i-oocyte.
Ukongeza, le hormone ithintela umzimba womfazi kwaye emva kokuzalwa komntwana. Ngoko i-oxytocin emva kokubeletha ikhuthaza ukubunjwa kwesidalwa sowesifazane, ithatha inxaxheba ngokuthe ngqo kwinkqubo yokuhlambalaza.
Ingakanani i-analog yokufakelwa kweli hormone isetyenziswa rhoqo?
Ukwanda kwinqanaba le-oxytocin egazini lomfazi okhulelweyo lisebenza ngomzimba njengombonakaliso wokuqala kokunikezelwa. Kungenxa yoko, kunye nexesha elide labasebenzi, khuthaza inkqubo yokuhanjiswa kwe-oxytocin. Kule meko, isilwanyana sidla ngokulawulwa ngaphakathi, esikuvumela ukuba ufikelele ngokukhawuleza umphumo oyifunayo. Sekunjalo ngokoqobo imizuzu embalwa emva kokulawulwa, ukuphindaphindwa kwee-muscle fibers ze-myometrium kwanda, okwandisa ubukhulu kunye nokuphindaphindiweyo kwezinto eziphambeneyo.
Kwakhona, le hormone ingasetyenziselwa ukukhutshwa kwangaphambili kwephacenta, apho kwiimeko ezithile kunokuba nzima.
Yintoni enokuyenza xa umzimba unomgangatho ophantsi we-oxytocin?
Ngaphambi kokunyusa izinga le-hormone oxytocin kwigazi lomfazi, kufuneka adlulise uhlalutyo olufanelekileyo. Ukuba iyancitshiswa koko, ke unyango olunobungozi be-hormonal lubekwe.
Xa kuziwa kwabasetyhini abakhulelweyo abanamaqondo aphantsi e-oxytocin egazini, ngoko ke ukuhanjiswa kwangethuba, i-hormone ilawulwa kwangaphakathi. Kule meko, umyinge ubalwa kuphela ugqirha ngokusekelwe kwimeko yowesifazane okwangoku.
Ukuze ugweme le meko, abaninzi abanezinyama zezilwanyana bancomela ukuba banakekele ukuphakamisa izinga le hormone egazini kwangaphambili. Ngoko ngenxa yokuba i-hormone i-oxytocin iqulethwe kwezinye ukutya, umfazi angakwazi ukuzimela ngokuzimeleyo ukwandisa ukugxininiswa emzimbeni. Okokuqala, ezi zinto ziquka i-selenium: i-zucchini, i-squash, i-asparagus, isilimo esidliwayo esinamagatsha anamanzi, njl. Ukongezelela, isayinwe ibonisa ukuba ukuhlanganiswa kwe-oxytocin kwanda ngokubambisana, kumanga. Ngoko ke, elowo umntu, ngelixa umfazi ekhulelwe, kufuneka abe nesisa, ngovakalelo kunye nokuthuthumela, umphathe ngamazwi othando.
Iyiphi indima ye-oxytocin emzimbeni womfazi?
Ekuqaleni, i-hubbub ye-oktobini yowesifazane iveliswa kwi-hypothalamus, kodwa ihanjiswa kwi-lobe yangemva kwe-pituitary gland, apho emva kokuqokelelwa kukhutshwa kwigazi.
Imisebenzi ye-hormone i-oxytocin emzimbeni wesetyhini ilandelayo:
- ukuvuselela i-myometrium nge-uterine ngokunyusa umsebenzi wayo wesivumelwano;
- igalelo kwiintlobo ze-uterine kwimigangatho yesi-2 neye-3 yenkqubo yokuzalwa;
- ukwandiswa kwemveliso yeprolactin nge-pituitary gland;
- ukwandisa ukunqanda igazi, okukunceda ukuyeka ukuphuma kwegazi emva kokubeleka;
- ibangela ukunciphisa iiseli ezikuyo ngqo kwindawo ye-alveolar yeengqungquthela ze-mammary, ezikhokelela ekugqibeleni ubisi lwebele kunye nokunyuka kwama- lactation .
