Chokutanga, tichazonzwisisa izwi: metaplasia inoshandiswa mumamiriro ehutachiona, kuwanikwa kwahwo kwezviratidzo zveimwe mhuka mukati mehutano hwebhuruki rimwe remubryonic, kureva kuti, mhuka dzomukati mumwe chete. Kazhinji kazhinji ichi chiitiko chinowanikwa mu epithelial kana chinogadzirisa mavara. Maererano nekliniki inonzi classified, squamous cell metaplasia yemukirini inoreva kubata zvirwere.
Mechanism of the process of metaplasia
Metaplasia ye epithelium yemukirini inotora nguva yakakwana panguva yekuwedzera uye kuparadzaniswa kwezvitsva, zvinonzi, kuchengetwa kana masero emadziro . Mumuviri wemukati, iyo inotsanangurwa inowanikwa inonyanya panguva yekupararira kwemasero. Kazhinji kazhinji, masero e-single-layer prismatic epithelium (unhu hwemuviri wechibereko) inotsiva masero emasero akabatanidzwa akawanda (ari mumukadzi). Kana kuti zvinokambaira zvemasero epamisium epamineum mumasero emagetsi. Kazhinji, pane inowanikwa, yakajeka mutsauko pakati pe epithelium iyi.
Zvinokonzera metaplasia yemukati
Kazhinji kazhinji metaplasia inopindurwa nehutachiona hwehutachiona hwechirwere, somuenzaniso, kuvhuvhuta, utachiona, kuchinja mumarimoni emuviri wemukadzi, kutyora kwepH yemukadzi, kana chiratidzo chekuporesa kwekutsvaira kwemuviri wechibereko . Apo hutsinye hunoshungurudza hwezvinhu zvinogumbura zvinoguma, mhuka yacho inodzokera kune yakagadziriswa morphological structure.
Chii chaungaita nemetaplasia?
Hazvidikanwi kuti nguva isati yasvika, kusagadzikana epithelium pachako hakusi kuipa kunogadzirisa uye hakutsananguri nemamiriro ezvinhu anononoka. Kunyange zvazvo isiri iyo nzira yakanaka uye inoda kuongorora zvakare uye kujekeswa kwechikonzero chinokonzera. Iko kufanana nekuchinja kwemuviri kwemuviri kushandura mamiriro ezvinhu, kupa chiratidzo pamusoro pehutachiona huripo. Mushure meizvi, kurapwa kwomunhu mumwechete we metrolasia inofanira kuitwa. Chero zvazvingava, chirwere ichi chinoda kugara chichiongororwa nechiremba anoenda.
