Isiqhelo se-hemoglobin egazini labesetyhini

Ukusebenza komzimba wesetyana kunzima kakhulu kunokuba kwindoda, kuba umsebenzi walo kuxhomekeke kumlinganiselo wokugqibela we-endocrine. Ngokomzekelo, inkqubo ye-hematopoietic inempembelelo enkulu kwi-hematopoiesis. Ngenxa yoko, isiqhelo se-hemoglobin kubasetyhini asisoloko sigxina kwaye siyahluka ngokukhawuleza ngokuxhomekeke kumhla wokuhamba kwimihla , ubukho bokukhulelwa.

Injani i-hemoglobin ekuhlaziyeni kwegazi kwabafazi?

I-hemoglobin ye-pigment ye-pigment iqukethe insimbi kunye neprotheni. Akaxanduva lokunikela ngegazi elibomvu, kodwa kunye nokuthutha i-oksijeni. Emva kokuba umbane we-biological uqhutyiswe ngomoya kwimiphunga, i-oxyhemoglobin yenziwa. Ijikeleza egazini legazi, ukuhambisa i-oksijini kumalungu kunye nezicubu. Emva kokuqhekeka kwee-molecules zegesi, i-carboxyhemoglobin equlethwe kwi-bio fluological fluid iyafumaneka.

Ukumisela isiqhelo se-hemoglobin emzimbeni, ukuhlolwa kwegazi kwenziwa kubasetyhini, oku kuquka ukubala inani elipheleleyo le-pigment e-organic in capillaries okanye emithanjeni.

Iyiphi inqanaba eliqhelekileyo le-hemoglobin egazini labesetyhini?

Ingxininiso yecandelo elihlolwe i-erythrocytes ayinciki nje kuphela kwisini, kodwa nakwixesha elide:

1. Ngaloo ndlela, kubasetyhini abaqhelekileyo, iimpawu eziqhelekileyo ze-hemoglobin zivela kwi-120 ukuya kuma-140 g / l.
2. Amazinga aphakamileyo asemgangathweni amele abantu ababhema (malunga ne-150 g / l) kunye nabadlali (ukuya kwi-160 g / l).
3. Ukunciphisa ubuncinane be-hemoglobin umxholo kubonakala kwabasetyhini abadala kuneminyaka engama-45-50-ukusuka kwi-117 ukuya kwi-138 g / l.

Kubalulekile ukuba uqaphele ukuba izithethe ezichazweyo nazo zichaphazelwa ngumhla wokujikeleza kwakhe. Inyaniso kukuba ngexesha lokuya esikhathini, umzimba wesifazane uphulukana negazi kwaye, ngokufanelekileyo, isinyithi. Ngoko ke, ngokukhawuleza emva kokuphela kokuya esikhathini, isantya se-hemoglobin kwisini esifanelekileyo sinokuncitshiswa ngamaqumrhu ama-5-10.

Isiqhelo se-hemoglobin epheleleyo egazini labasetyhini abakhulelweyo

Ukuzala umntwana kubandakanya utshintsho olukhulu emzimbeni, oluchaphazela imvelaphi ye-hormonal kunye neprogram ye-hemopoietic.

Kwi- trimester yokuqala yokukhulelwa, ukuguquka okuphawulekayo kwi-concentration ye-hemoglobin akufanele kwenzeke. Ngokuqhelekileyo, ixabiso eliqhelekileyo lisetyenziswe kwibanga ukusuka ku-105 ukuya ku-150 g / l.

Utshintsho oluphawulekayo kwimiba ye-pigment ye-pigment inombandela evela ekuqaleni kwe-trimester yesibini. Oku kuchazwa yinyaniso yokuba, ngokukhula kwe-fetus, umthamo opheleleyo wegazi ojikelezayo emzimbeni womama ozayo uya kwanda malunga nama-50%, kuba inkqubo yegazi kubo kunye nosana ngowesibini. Kodwa inani le-hemoglobin alinyuli, kuba umongo wethambo awukwazi ukuvelisa le pigment engokwemvelo ngokunyuka kwamanani. Kufuneka ukuba uqaphele ukuba isinyithi equlethe i-hemoglobin sele isetyenziselwa ukubunjwa kwembungu kunye ne-placenta ecaleni kwayo. Ngoko ke, oomama abazayo bayacetyiswa ukuba bajonge ngokugqithiseleyo ukusetyenziswa kwezidakamizwa ezineetsimbi okanye iivithamini ngale nxalenye yokulandelela. Emva koko, xa uqhuba iimfuno insimbi ikhula ukusuka ku-5-15 mg ngosuku, ukuya kwi-15-18 mg ngosuku.

Ukuqwalasela ezi ngongoma ezingentla, iimiselo zecandelo elichazwe ngamaseli obomvu amabhinqa akhulelwe aphuma kwi-100 ukuya ku-130 g / l.

Ngokuqinisekileyo, ukubaluleka kwe-hemoglobin eqhelekileyo kumama ngamnye wesikhathi esizayo kuyomntu ngamnye kwaye kuxhomekeke kwiminyaka yobudala, imeko yempilo yowesifazane, inani leziqhamo (kwi-embrasi 2-5, i-hemoglobin incinci kakhulu kuneyona evamile). Kwakhona kuchaphazela inkqubo yokugaya, ukufumaneka kwezifo ezingapheliyo kwenkqubo yokujikeleza kunye neengxaki zokukhulelwa.
