Okokuqala, siya kuqonda isigama: i-metaplasia iyitshintsho kwiipropati zezicubu, ukufunyanwa kwayo ngeempawu zesinye isisu phakathi kweentlobo ezahlukeneyo zamagqabha emhlophe, oko kukuthi, izicubu zesigxina esisodwa. Ngokuqhelekileyo esi siqhelo senzeke kwii-epithelial okanye izicubu ezixhamlayo. Ngokwezigaba zeklinikhi, i-squamous cell metaplasia yomlomo wesibeleko ibhekisela kwiinkqubo ezinobungozi.
Inkqubo yenkqubo yemetaplasia
I-metaplasia ye-epithelium yomlomo wesibeleko iyenzeka ixesha elide ngexesha lokusasazeka kunye nokwahlukana kwezinto ezintsha, ezibizwa ngokuba, zigcinwe okanye ziseli . Kwi-cervix, inkqubo echazwe iyenzeka ngokukhawuleza ngexesha lokusasazeka kweeseli. Ngamaxesha amaninzi, iiseli ze-prismatic epithelium (uphawu lwesalathisi somlomo wesibeleko) zithathe iiseli zamaseli adibeneyo amaninzi (aphakathi kwesini). Okanye ukunyuka kweeseli ze-epithelium ezinqamlekileyo zibe ngamaseli angama-cylindrical. Ngokuqhelekileyo, kukho umda obonakalayo, ocacileyo phakathi kwezi epithelium.
Iimbangela ze-metaplasia yomlomo wesibeleko
Ngokuqhelekileyo i-metaplasia yindlela yokuphendula kwinkqubo yesifo esingapheliyo, umzekelo, ukuvuvukala, ukusuleleka, utshintsho kwimvelaphi ye-hormone emzimbeni wesifazana, ukuphulwa kwe-pH yesisu, okanye uphawu lokuphulukiswa kwindalo yesisu . Xa iimpembelelo ezinobuhlungu zendalo ziphelile, izicubu zibuyela kwisakhiwo sayo esiqhelekileyo se-morphological structure.
Yintoni enokuyenza nge-metaplasia?
Akuyimfuneko ukusazela kwangaphambili, i-metaplastic epithelium ngokwayo ayiyiyo into eyingozi kwaye ayibhekiseli kwiimeko ezinqabileyo. Nangona akusiyo inkqubo efanelekileyo kwaye idinga uviwo olongezelelweyo kunye nokucaciswa kweyona nto. Kufana nokuphendula okuguquguqukayo komzimba ukutshintsha iimeko, ukunika isalathiso malunga nenkqubo ekhoyo ye-pathological process. Emva koko, unyango ngamnye lwe-metaplasia yomlomo luya kwenziwa. Kukho nawuphi na, esi sifo sidinga ukubeka esweni rhoqo ngugqirha.
