Aplasia - a zokugula ezingathinta kabi noma isiphi isitho

Aplasia - ibonakalisa kombungu, okuyinto sivezwe kula ukungabi khona noma iyiphi ingxenye yomzimba noma izicubu izigaba. Lokhu zokugula kuyinto okumelwe ahlukaniswe kusuka hypoplastic lapho umzimba kungase kube isakhasa noma encishisiwe ngobukhulu futhi khulula isakhiwo evamile.

Yingakho kukhona zokugula

Kufanele kuqashelwe ukuthi aplasia - yesifo azalwa naso ukuthi kwenzeka ngenxa umthelela embungwini ngokuqondile noma ngokungaqondile ngokusebenzisa umzimba kamama ka ephathelene nomzimba namakhemikhali awo kanye izici zokwakheka komuntu. Bona, ukulalela gametes abazali noma okhokho bawo, kungabangela kwezinso chromosomal nge ukungabi khona uhlaka noma izicubu.

By the way, i ongakasetshenzwa eyodwa isitho embryo kuyinto awahlangani futhi uhola ngokuvamile ukufa okuhlobene nezinye umzimba. Ngokwesibonelo, e-ukungabi khona ihlumela ureteric kwenzeka yesibili kwezinso aplasia, futhi m. P.

Usuku asikiwe, ngemva kwalokho izici ezichazwe umbungu ayisakwazi ukuthuthukisa, - lena inyanga yokuqala yokuphila intrauterine.

Izici kumiswa zokugula

akukho ndawo lapho asikwazi waphawula aplasia kubantu. Lesi simo sokugembula elilodwa kwezitho abhanqiwe ngokuvamile ibangela enye hypertrophy (aplasia omunye nezindlala endocrine kungadala hypertrophy we abanye). Ngakho, kukhona esikhundleni, isinxephezelo imisebenzi elahlekile.

Ngokuvamile akukho ingxenye yomzimba, ezifana aplasia of the callosum Corpus noma ubuchopho olfactory (isifo okuthiwa i arinentsefaliey), njll Aplasia ijwabu ngokuvamile kubonakala ekhanda. Kuleli qophelo embhalweni usana ozalwa isici itholiwe, ngokuvamile ingeqi 5 cm. Kodwa isimo esinjalo kuhlangene, elitholakala ezijulile, isibonelo njengoba umthetho, izicubu aplasia, esimweni embryonic izimbotshana selivaliwe (t. N. Dizarfiya).

ukuthuthukiswa okungavamile ithambo izicubu

Njengoba kulezi zimo ezichazwe ngenhla, aplasia thambo ifomu acezile kumane ezingavamile kakhulu. Ngakho, lapho isifo onjalo esitho fibula nesineke mfushane eba equinovarus unyawo deformity (ngaphambili onqenqemeni ngesikhathi esifanayo ezikhulela kuyo yangaphandle - ivinjelwe), tibia lwalugobile, akukho ithole imisipha peroneal.

Aplasia amacala ngabanye ezilotshwe wezokwelapha izingxenye zomzimba, ngokuvamile kwenzeka nemilenze womuntu. Lokhu kungaba yokuntula isakhi esisodwa noma ngaphezulu iminwe noma sonke isandla noma unyawo. yokuntuleka njalo zokukhonjiswa ibhodi lemisindo, umbala, ehlombe, ethangeni, ebukhoneni unyawo noma isandla.

Aplasia we kogebhezi nobuchopho

Lapho aplasia ebalulekile amathambo skull, okuyinto kwezokwelapha ubizwa nangokuthi "skull fenestrated", kwakheka ngokusebenzisa ukukhubazeka ukuba usayizi ezahlukene kanye shape. Kodwa periosteum (ulwelwesi fibrous ukumboza bone) kanye isikhumba endaweni la ukukhubazeka ahlale. Basuke etholakala ikakhulu parietal futhi frontal izifunda.

Uma usana olusanda kuzalwa akukho amathambo Yekhanda, ngokuvamile nabo lapho umnkantsha aplasia (Ibizwa nangokuthi anencephaly). Lokhu zokugula 100% ebulalayo. Ngaphezu kwalokho, u-75% izingane basafa e utero, kanti bonke abanye baphile akukho kuka izinsuku 5 emva kokuzalwa.

Nakuba kunjalo aziwayo lokuzalwa e-United States ngo-1992, intombazane kokutshelwa ngokukhubazeka kwengane, owaphila eminyakeni 2 nezinsuku 174. Ukuphefumula futhi ukusebenza kwezitho zangaphakathi ku isidumbu sakhe owenziwa walondoloza ubuchopho stem. Kodwa, noma kunjalo, le ntombazane ezikhathini ezithile uxhumeke ngomshini kanye nezibhelu ezilandela lokhu abasafufusa kuholele stop yayo.

Aplasia kwesibeletho futhi emomozini

Amacala nokungathuthuki noma ukungabi khona kwesibeletho, fallopian amashubhu kanye emomozini - angahlangani akuvamile ihlangabezane. Abesifazane abanalo, awukwazi okukhulelwa noma enze ingane yakho.

Inkinga itholwa ngokuvamile kakade ukufinyelela nokuthomba. Kowesifazane udokotela ukuletha izikhalazo ngokuntuleka esikhathini (ngokungabi bikho sangasese), ukungabi nakwenzeka aphila ngayo ngokobulili. Kulokhu, isiguli ngokuvamile igcinwa ekwakhekeni nasekumeni komzimba evamile futhi evuthiwe izici ngokobulili yesibili.

Uma isiguli sine-aplasia ngokwengxenye sangasese, kungase akhononde nyangazonke acinene ukopha, webele isisa umdwebo izinhlungu esiswini engezansi, okuyinto ahambisana ekuqongeleleni ukugeleza kokuya esikhathini, selokhu outflow uma uphethwe lakhe lingeke ladalulwa.

into okunjalo kuholela ekuphikeni zokwakheka isimila - the hematocolpos okuthiwa. Njengoba zikhula, ephansi besisu ubuhlungu isiyaphuma avele abukhali, nalapho suppuration imali kusheshisa lokushisa likhuphuka, ukudala izimo ezikahle ukuze sepsis. Isiguli kulokhu kubonisa eyohlinzwa esiphuthumayo.

Lapho izimila esibelethweni akuyona akukho ndlela, ngoba akukho emzimbeni, ukukhulula igazi.

Aplasia - akusiwona isigwebo sokufa njalo

Umthelela on the umzimba womuntu aplasia kwezitho ezahlukene, izicubu noma izitho zomzimba lihlukile. Ezinye izinhlobo aplasia (engekho ama- cerebral, imisipha yenhliziyo, kokubili izinso, nokunye. N.) Ingabe aluhambisani nawo ekuphileni. Abanye kungabangela ukungasebenzi kabi umzimba, futhi akukho ukuhlinzwa kuzoholela ukufa isiguli (hernia diaphragmatic , noma Hirschsprung isifo).

Kodwa ukungabi kwengxenye noma kwakho konke esinye sezitho zomzimba wakho, kanye aplasia kwesibeletho, iyahambisana ukuphila. Ipheya elilodwa umzimba ezibalulwa kanjena ngokufanele, ezifana sohlangothi olulodwa aplasia kwezinso, hypertrophy ngezinye izikhathi ihlawulelwa ngokugcwele lomunye, futhi ngaleyo ndlela kungenza emtholampilo ukuzibonakalisa kukho konke ukuphila kwesiguli.
