Teratogenic Migumisiro: zvinhu

zvinodhaka Teratogenic kunokonzera chimiro urema, uyewo mwana kukura anomalies nokuda kushandisa kwavanoita mai panguva yepamuviri. Teratogenesis anovandudza pasi pokudzora zvinokonzera kuita kubva kunze pamusoro zvichiitika mutumbi mudumbu Zvinogonekawo pasi pokudzora enhaka zvirwere.

Pane akafanirwa?

Teratogenic migumisiro nokuda kwemutemo zvinodhaka kana ravo kushanduka zvinhu kuburikidza chipingamupinyi pakati dumbu uye placenta, nokudaro kuvhiringidza paumbwe zvomukati uye nyama embryo.

dzinonetsa nguva

Panguva dzakasiyana zvokukura pamuviri pane siyana kukuvadzwa chokuita anotevedzana paumbwe hurongwa muviri - ichi ndiyo yakaoma. Zvikuru ngozi panyaya zvakakomba kutyorwa ndiwo 2-3 mwedzi pamuviri rokutanga. Zvinofanira kucherechedzwa kuti pane imwe yapfuura padanho pasi pokudzora zvinhu kutyorwa zvakadai kuitika uyewo ari zvichiitika mumuviri, asi ivo haawirirani upenyu: pane kupfupfudzika (vaingoerekana pamuviri). Critical nguva nokuti miviri yakasiyana akasiyana: Mazuva 23-28 fetus kukura zvinokosha uropi, 23-45 zuva - nokuti nhengo nechaanoona, maoko nemakumbo vari yakaumbwa pazuva 28-56 zuva uye zvichingodaro.

Zvii kukonzera?

Teratogenic matambudziko anokonzerwa zvinhu zvinotevera: zvinodhaka, zvirwere (rubella, herpes, cytomegalovirus, parvovirus, njovhera, toxoplasmosis), metabolic zvirwere mu pamuviri (endemic goiter, decompensated cheshuga, kwenguva refu pyrexia, androgen mapundu), zvinodhaka (androgens, methotrexate, captopril , enalapril, iodides, methimazole, tetracyclines, thalidomide, valproate, warfarin, busulfan), ionizing nemwaranzi (nemwaranzi kurapa nokuda kenza, kurapa pamwe radioactive ayodhini, adioaktivnye kunonaya) uye zvakawanda.

Zvinoumba simba

Zvinhu izvi sei zvimwe zvinhu. Teratogenic migumisiro nokuda dose. Uyezve, asati nokufumura chero chinhu subthreshold anokoshesa malformations ari mudumbu haasi kuumbwa. Teratogenic migumisiro dzakasiyana mhando uye kunyange pakati zvakasiyana vamiririri chete kwemarudzi angava akasiyana, nokuda mumwe unhu muviri (Absorção de Água, kuparadzirwa uye excretion mumuviri raamai uye zvakananga zvinopfuura uterine-placental chipingamupinyi). Zvisinei, kana pachena zvirwere muviri mai Hazvibviri kuona pachikumbaridzo dose.

vachiparadzira chinhu

Teratogenic zvinhu inowanzobvunzwa anowanikwa zvakatipoteredza. Somugumisiro zvidzidzo yakawana kuti mukadzi panguva pamuviri zvinotora anenge 3-4 zvinodhaka. Uyewo, vakadzi vane pamuviri vari kubasa kana kumba kuonana siyana yeimwe hunokuvadza. Teratogenic mishonga vanofanira kuiswa iri tsvakurudzo: kuti nekusimba kubatana pakati zvakananga simba pamusoro chinhu chakaonekwa kuremara nokusimbisa epidemiological mashoko. Uyezve, kushanda chinhu chinofanira nezvatakarerekera dzinonetsa nguva.
