Decidua izicubu: definition, izinkomba kanye nezici

Umzali noma decidua, izicubu elise phakathi nele-embryo ne kwesibeletho, kubalulekile ukuba zokwakha ye-yolk sac sokukhulelwa, ukuthuthukiswa kwe-fetus, ukuzalwa kwengane enempilo.

lokukhulelwa

Mature zesifazane germ cells uyakwazi isishiya impilo entsha. Iqanda, zizungezwe izigidi isidoda tube fallopian, vuma eyodwa nje, ihlangana ne-ke yinye. Amahora angu-24 yokuqala iqanda eselivundisiwe iyona iphila kunazo, umthelela izici zokukhulumisana ezilimazayo imvelo iyalimala akunayo imiphumela emibi. Lokhu kungenxa amandla ephezulu ukuvuselelwa.

Ngu ngosuku 4-5-th kusuka ngesikhathi sokukhulelwa iyona core, kokuba ibanga elide, iwela ngalo ingaphakathi lesizalo. Ngalesi sikhathi, iqanda avundiswa kaningi wabelane, aluthola amakhono entsha, imisebenzi ezidingekayo.

Iqanda kudedela enzyme akhethekile, elikwaziyo ukuncibilikisa endometrium - ulwelwesi abami kwesibeletho. Uma iqanda eselivundisiwe amkhethile indawo, kuba oncibilikayo ingxenye endometrium kwakubenza nendawo yokuhlala, it is busuka ingaphakathi lesizalo. Lokhu ihlala cishe 2 izinsuku. Hole ngenhla isayithi nolwelwesi ikhula, ukwakha uhlobo ophahleni ngendlu yakhe. Khona-ke okwamanje sokukhulelwa, inqubo uphela.

Lwamafinyila edonsa amandla imfihlo adingekayo-embryo yoke, - jelly royal.

izigaba zokuqala wokukhula kwengane esiswini libhekene ukubukeka amagobolondo ezintathu, amniotic fluid ezizungezile ekuvikeleni sondle ke.

Izikhumba esibelethweni:

• decidua izicubu;

• fleecy;

• amanzi.

imisebenzi decidua

Ngesikhathi kufika endometrium esibelethweni is ibe decidua, ukuhlinzeka izimo ezidingekile umsebenzi umbungu. Ukuthuthukiswa esibelethweni kanye ukuguqulwa endometrium okufanele uhambe kanyekanye, noma yenzeka ingekho, ukukhulelwa kuphazamisekile ku izindawo ekuseni.

Caduca - ingxenye komama umzanyana, echaza umsebenzi walo:

1. Ukudla, ngoba iqukethe glycogen, lipids, mucopolysaccharides, nosawoti, izakhi trace, ama-enzyme, immunoglobulin, ayisiza.

1. Ukuvikelwa, njengoba enakekela zonke Amagciwane, ubuthi, izinto eziyingozi.

1. Development, kusukela emva wonke umsoco ziphele, iqala synthesize carbohydrate, amafutha, amaphrotheni, ama-hormone.

1. Immune futhi endocrine umsebenzi.

iziphazamiso ezazingase zibe khona ku isakhiwo ulwelwesi

Kukhona izinhlelo eziningi indawo futhi zesifunda, ukuqapha, aphatha ngayo abesifazane abakhulelwe, abesifazane abakhulelwe, izinsana. Izidingo zohlelo isifundo esiphathelene yi-placenta, kungakhathaliseki ukuthi umuntu mdala sokukhulelwa, indlela ukuthi kwenziwe ukulethwa. Lucwaningwa ezisicasulayo decidua izicubu.

Inhloso yalolu cwaningo sithi:

• ukuqashelwa kanye nokubhaliswa izici ezikhona ingozi lesi sifo lapho ukhulelwe;

• ngesikhathi esifanele isixwayiso izifo ezisanda kubelethwa;

• ukwelashwa kanye nokuvimbela yezinkinga yokukhulelwa kanye kwesikhathi kwangemva kokubeletha;

• ukuhlolwa izinga, ikhumbula Ukwenza abesifazane eyalandela okhulelweyo;

• ukuhlonza izimbangela kwezingane;

• ukuvezwa izizathu ukufa fetus.

Zonke ukuhlolwa esengeziwe kwenziwa, usebenzisa izindlela ukuxilongwa umehluko. Ukuhunyushwa imiphumela senziwa maqondana kukamama kanye nengane.

Decidua izicubu kungaba nezinguquko ezilandelayo:

• ukopha;

• necrosis;

• aphambane;

• ukuvuvukala;

• ukuqina.

Konke lokhu kwaziswa usungenile amarekhodi zezokwelapha abesifazane kanye kuzalwa, umlando inkathi yokukhulelwa, ukugula, amarekhodi esibhedlela, acabangele ngokuba ezimali sinenkonzo yokunakekela iziguli emakhaya Dispensary.

necrosis

Necrosis - ukufa izicubu wendawo esiholela endaweni ukuvuvukala e ukugeleza kwegazi ukuze izicubu futhi engavikelekile nezilwanyana ezincane kanye nemikhiqizo yabo umzimba. Lokhu kwazicasula mzimba, endocrine, secretory umsebenzi igobolondo izicubu decidual iqala iba yingxenye yomhlabathi futhi wasenqaba.

hyalinosis

Hyalinosis - uhlobo ukuvuselelwa nezicubu kubekwa uphawu, lapho uyofana uqwanga. Imbangela hyalinosis decidua izicubu is akukaqondwa ngokuphelele. Kodwa-ke kuholela ukopha okukhulu, wazalwa kungakabi isikhathi, ukuzalwa kwengane isishonile.

ukuvuvukala

iziyaluyalu kwegazi, kukhuphuke permeability semithambo, edema, ukwakheka ngokweqile wesabelo Ushintshe kwamaseli elichaza ukuvuvukala. Esikhundleni yisishiso ivame inqwaba egazi, livela decidua izicubu nge leukocyte kokuziphatha, okuyinto ekuqaleni ine uhlamvu oluhambelana. Kodwa nge ukuqhubeka le ndwangu afuthwe ngesibulali inqubo lenqwaba amangqamuzana amhlophe egazi, ubomvu livela. Ngisho nangemva kokuba yokwelashwa okuphumelelayo yenqubo ubovu nakanjani kwakhiwa ukuvuvukala engaholela nenzalo. Yileyo indlela eziyingozi decidua izicubu ukuvuvukala.

Izizathu kungaba: endometritis, yisishiso amniotic fluid lapho ukutheleleka okudlulela ngokuthintana. Ehamba ukopha, okungaholela isisu ku term mayelana 3 izinyanga yokukhulelwa. endometritis Decidual livela belyami uchichima ezinyangeni zokuqala ngemva kokubamba. Nge ukuqhubeka inqubo yokuthuthukisa amakhono kwesisu ngasekupheleni, ukungeza, ngaphambi kwesikhathi lamabutho yomzanyana lesizalo involution.

ukopha

Ngezinye izikhathi decidua izicubu ne ukopha. Kutfutfukisa ngesikhathi ukuchithwa kwegazi ngaphandle kodonga umkhumbi permeability okusezingeni eliphezulu, encibilika nofana ukuphula ubomvu nomgudu sokugembula. Kubonakala isisu nokuguqulwa, ukhulela ethunjini, horionkartsinoma.

igebe

Ngezinye izikhathi kukhona igebe futhi kukhona kuphela izinsalela decidua izicubu. ukudabuka singakafiki isikhathi kuholela ekubeni amagobolondo eside isikhathi anhydrous ephelezelwa kwengozi yokutheleleka, ukopha. Utfutfukisa ephethwe izifo ezifana izifo igazi, isifo sikashukela, khona inani elikhulu kwezisu ukukhulelwa odlule.

Igobolondo liyakwazi ukwandisa umthamo ebukhoneni ukuvuvukala, ukonakala, sesatshiswa isisu.

Izizathu izinguquko decidua

• angahlangani bofuzo umbungu.

• izinqubo okuvuthayo kwesibeletho.

• kahle kwegazi.

• Ukutheleleka.

• isifo Hemolytic.

• zokugula Extragenital: sikashukela, izifo zenhliziyo, izifo igazi, yegilo, isimiso sezinzwa.

Ngokuba nokuvimbela isisu ezisengozini kuyadingeka ukwenza kube efiselekayo. Kuyadingeka ukulungiselela, ukuhlela kusengaphambili, ukuze ahole indlela yokuphila enempilo, ukuqeda yokwamukela utshwala nogwayi, ukwelapha zonke ukuphathwa kwabathintwayo nezifo ezithathelwanayo kanye ukuvuvukala.

Ngaphambi uhlela ukukhulelwa kufanele abe egazi noma omchamo ukuhlolwa (ku igazi ekunqandeni, ama-hormone), ukuthola iqembu omama igazi ihlolwe izifo esicashile. iqembu Igazi, RH isici futhi ukuhlolwa ukutheleleka esicashile kukhona kokubili abazali. Ukuze uhlu edingekayo kwegazi for ukutheleleka yilezi: toxoplasmosis, rubella, cytomegalovirus, herpes.

Esimeni ukukhulelwa kusenesikhathi kungcono ukuba babhalise e emtholampilo, udokotela njalo, ukugcwalisa zonke iziphakamiso zayo, ukuthatha ukuhlaziya isimo ngendlela esifike ngesikhathi.
