Mhuri dzakaroorana dzinosarudza kuwana vana hazviwanzofungi nezvehutano hwemapoka eropa nokuda kwekubata pamuviri, kunyanya kana mushure mekushingaira vanogamuchira mhinduro yakanaka. Uye chete kana pane nguva yekukundikana, inguva yekufunga nezvezvikonzero. Chimwe chekukundikana kwakadaro kusinganzwisisiki kwevashanduki pakubata pamuviri. Kusagamuchirwa kwevakaroorana muboka reropa uye Rh factor ndewokuti hapana mhirizhonga, nokuti nekubatanidzwa kwekuzvimba kunogona kuitika. Chimwe chinhu ndechekuti kusanganiswa kwemapoka eropa akasiyana uye rhesus kunogona kukonzera nguva yekuzvitakura.
Kubatana kweropa nekuda kwemimba
Izvo zvikamu zvikuru zveropa zvinokanganisa nguva yekuzvitakura iropa boka uye Rh factor (Rh). Kuratidzirana kwakanaka kweropa pakuberekwa kwomwana - mazana emaropa uye Rh zvimwe zvevakaroorana, asi izvi hazvisi zvisizvo. Chinhu chinonyanya kuipa kumwana asati aberekwa ndechekusagadzikana kweH Rh panguva panguva yekurohwa.
The Rh factor is a protein (antigen) iyo iri pamusoro penhengo yeropa tsvuku (erythrocyte), uye vanhu vane antigen iyi vanonzi Rh-positive, uye vasina Rh-negative. Kana amai vane Rh asiri uye chibereko chinoguma chinowana Rhesus yakanaka, mhuka yemadzimai inotanga kubudisa zvirwere zvinopesana ne erythrocytes ye embryo (i erythrocytes ye fetus inononoka kupinda mumuviri waamai kuburikidza nechigadziro chinokonzera).
Kusagadzikana kwakadaro pakati pemadzimai nemwana kunogona kukonzera kusapererwa pamuviri munguva yekutanga, intrauterine fetal death munguva inotevera kana kukura kwehemolytic chirwere chechecheche. Muhosha ye hemolytic, fetal erythrocytes inoparadzwa, kupererwa kwehutachiona kunoitika, chiropa chinowedzera uye chirwere che bilirubin muropa rechecheche rinowedzera.
Kuvhiringidzika kwemazana emaronda munguva yekuzvitakura kwakawanda kudarika uye kunoratidzira sehosha ye hemolytic yemucheche wakaberekwa.
Nzira yekutungamira sei pamuviri nekusawirirana neboka reropa uye Rh factor?
Kana Rh-asina kunaka ari kuronga kubata pamuviri, anofanira kutarisisa huwandu hwezvirwere muropa kusvika kuR Rh factor. Mushure mokutanga kwekuita pamuviri, kubva pamasvondo manomwe mwedzi mumwe nomumwe unofanirwa kutarisa huwandu hwesiramende muropa risati rapera. Mushure mekuberekwa, mukati maawa makumi manomwe nemasere, zvakakosha kuzivisa immunoglobulin antiresusive, iyo inodzivisa kuumbwa kwezvirwere mumakamu amai kana ropa rekuberekwa richirayiwa munguva yebasa.
Kubatana kwevadzidzi pamwe chete pakuita pamuviri
Chikonzero chekusagadzikana kwevadzidzi vanogona kugadziriswa nehutano hwekuedzwa kwemimba, iyo inonzi postcoital test. Uyu muedzo unoitwa muchikamu chekuvhura, zvichienderana nezvinotevera zvinotevera:
- zvakakosha mazuva matatu kuti urege zvepabonde;
- Pamberi pechiito chepabonde vanoita maitiro ehutsanana, uye vasati vasvika kuna chiremba kwete seringiri;
- Usabva pamubhedha mushure mekuita zvepabonde kwemaminitsi makumi matatu, uchiisa chidzitiro chekuchenesa kuti urege kurasikirwa nemasikirini emvura;
- kune gynecologist haafaniri kuuya mberi kwemaawa matanhatu uye kwete pashure maawa gumi mushure mekuita zvepabonde.
Kuti uone kuwirirana kwevamwe vakabatana pakubata pamuviri, tora muenzaniso wekusvina kubva mumuviri wemukati, shandisa iwo pakati pemasvidi maviri uye uongorore pasi pe microscope. Sarudza kusagadzikana kwemukoko, crystallization, yakawandisa uye pH yepakati.
Kuongororwa kwechimiro che spermatozoa pachiyero kubva pa "A" kusvika ku "G" kunoitwa:
- dhigirii "A" rinoenderana nekufamba zvakanaka kwakanaka;
- dhigirii "B" kufamba kunonoka, kwakasvibiswa uye kusingarevi;
- dhigirii "B" kufamba pasina-progressive;
- dhigirii "G" spermatozoa haina kusimba.
Kuwirirana kwevamwe vanobatana pakuberekwa hakusipo nehuwandu hwemhando ye spermatozoa "B" uye "G"; hutema, veccocc, cristallizing cervical mucus nemhando yakashata yepakati.
Kana kusakundikana kwekuedza kuita pamuviri usaora mwoyo, nokuti mushonga wemazuva ano une chikwata chikuru chezvikonzero zvekubatsira vana vasina vana. Nzira dzakadai se intrauterine insemination kana in vitro fertilization dzichabatsira mhuri dzisingakwanisi kugadzirisa dambudziko risina kuwirirana pakuberekwa kwomwana uye kuwana mwana akamirira kwenguva refu.
