Chiremba wezvekuzvara anozivikanwa nekutarisa kwake uye tsvakiridzo pamusoro penhumbu dzakawanda akawana kuti kuchinja kwekudya kunogona kukanganisa mikana yemukadzi yekuzvara mapatya, uye kuti mikana yese inotarwa nekusanganiswa kwekudya uye nhaka.
Nokuenzanisa mapatya evakadzi vevegan vasingadyi zvigadzirwa zvemhuka nevakadzi vanodya zvigadzirwa zvemhuka, Dr. Gary Steinman, chiremba wevashandi paLong Island Jewish Medical Center muNew Hyde Park, New York, akawana kuti zvigadzirwa zvevakadzi, kunyanya mukaka. zvigadzirwa, zvine mukana wakapetwa kashanu wekuita mapatya. Chidzidzo ichi chakaburitswa muna Chivabvu 20, 2006 chinyorwa cheJournal of Reproductive Medicine.
The Lancet yakaburitsa tsananguro yaDr. Steinman pamusoro pemigumisiro yezvokudya pamapatya munyaya yayo yaMay 6.
Mhosva inogona kuva insulin-yakafanana nekukura factor (IGF), puroteni inovanzwa kubva pachiropa chemhuka - kusanganisira vanhu - mukupindura kukura kwehomoni, inotenderera muropa, uye inopinda mumukaka. IGF inowedzera kunzwa kwemaovari kune follicle-stimulating hormone, kuwedzera ovulation. Zvimwe zvidzidzo zvinoratidza kuti IGF inogona kubatsira embryos kurarama matanho ekutanga ekukura. Iko kusungirirwa kweIGF muropa revakadzi vegan inenge 13% yakaderera pane yevakadzi vanodya zvigadzirwa zvemukaka.
Huwandu hwemapatya muUS hwakakwira zvakanyanya kubva 1975, panenge nguva yakaunzwa tekinoroji yekubereka (ART). Kuregedza kubata pamuviri nemaune kwakabatsirawo mukuwedzera kwenhumbu dzakawanda, sezvo mukana wemukadzi wekuzvara mapatya uchiwedzera nezera kunyangwe pasina chirongwa cheART.
"Kuramba kuchikwira kwemapatya mu1990, zvisinei, kunogonawo kuva chikonzero chekuiswa kwehomoni yekukura mumhou kuti ivandudze kushanda," anodaro Dr. Steinman.
Muchidzidzo chazvino, Dr. Steinman paakaenzanisa mapatya evakadzi vanodya zvakajairika, vanodya miriwo vanodya mukaka, uye vegans, vakawana kuti vegans vanozvara mapatya zvakapetwa kashanu kazhinji pane vakadzi vasingasiyanise mukaka kubva mukudya kwavo.
Pamusoro pemhedzisiro yehutano pamazinga eIGF, kune genetic link mumhando zhinji dzemhuka, kusanganisira vanhu. Mumombe, zvikamu zveiyo genetic code inokonzera kuzvarwa kwemapatya ari padyo neiyo IGF gene. Vatsvakurudzi vakaita tsvakurudzo yakakura yevakadzi veAfrica-America, vachena, uye vekuAsia uye vakawana kuti IGF mazinga aive akakwirira muAfrica-America vakadzi uye yakaderera muAsia vakadzi. Vamwe vakadzi vane genetically predisposed kugadzira IGF yakawanda kupfuura vamwe. Mune idzi huwandu hwevanhu, iyo mapatya mamakisi graph inofanana neiyo FMI level graph. "Ichi chidzidzo chinoratidza kwekutanga kuti mukana wekuve nemapatya unotarirwa nezvose zviri zviviri nhaka uye zvakatipoteredza, kana, nemamwe mazwi, zvisikwa uye kudya," anodaro Dr. Steinman. Mhedzisiro iyi yakafanana neinocherechedzwa nevamwe vaongorori mumhou, zvinoti: mukana wekuzvara mapatya unopindirana zvakananga nehuwandu hwe insulin-sekukura kwechinhu muropa remukadzi.
“Nekuda kwekuti mimba dzakawanda dzinowanzosangana nematambudziko akadai sekuzvarwa nguva isati yakwana, kutadza kubereka, uye BP yaamai pane nhumbu dzesingleton, zvakabuda muongororo iyi zvinoratidza kuti madzimai ari kufunga kubata pamuviri anofanira kufunga kubvisa nyama nemukaka nezvimwe zvinovaka mapuroteni, kunyanya munyika. uko ma<em>hormone okukura anobvumirwa kupiwa kumhuka,” anodaro Dr. Steinman.
Dr. Steinman anga achidzidza maitiro ekuberekwa kwemapatya kubva paakatora mapatya mana akafanana mu1997 paLong Island EMC. Ongororo yake ichangoburwa, yakaburitswa mwedzi uno muJournal yeReproductive Medicine, pamapatya ehama, ndeyechinomwe munhevedzano. Vatanhatu vasara, vakaburitswa mujenari rimwechete, vanotarisa pamapatya akafanana kana akafanana. Pfupiso yezvimwe zvabuda inopiwa pazasi.
Ongororo Yakapfuura
Dr. Steinman vakaona kuti vakadzi vanova nepamuviri vachiyamwisa vane mukana wakapetwa kapfumbamwe wekuita mapatya kupfuura avo vasingayamwisa panguva yekubata pamuviri. Akasimbisawo ongororo dzakaitwa nemamwe masayendisiti dzinoratidza kuti mapatya akafanana anowanikwa zvakanyanya pakati pevasikana pane vakomana, kunyanya pakati pemapatya akabatana, uye kuti mapatya akafanana anogona kupfupfudzika kupfuura mapatya ehama.
Dr. Steinman, vachishandisa kudhinda zvigunwe, vakawana humbowo hwekuti huwandu hwevana vakafanana hunowedzera, misiyano yavo yemuviri inowedzerawo. Muongororo ichangobva kuitwa pamusoro pemagadzirirwo ekuzvara mapatya, Dr. Steinman vakatsinhira kuti kushandisa in vitro fertilization (IVF) kunowedzera mukana wekuita mapatya akafanana: kudyara mazai maviri kunobereka vana vatatu, akakurudzirawo kuti kuwedzera kwecalcium. kana kuderera kwehuwandu hwechelating agent - ethylenediaminetetraacetic acid (EDTA) munharaunda yeIVF inogona kuderedza dambudziko rematambudziko asingadiwi.
