Ngenxa yeemeko ezahlukeneyo zesifo, zangaphandle okanye zangaphakathi, izicubu eziphilayo zomzimba zinokuguquka kwaye zife. Ngeke kwenzeke ukubuyisela iiseli ezifile, kodwa kunokwenzeka ukuyeka le nkqubo, ukunciphisa ukusasazwa kwayo. Ukufumana unyango oluchanekileyo kuyimfuneko yokwazi zonke iintlobo ze-necrosis, ekubeni ukuchongwa ngokuchanekileyo kokuhlukana kwemvume kuvumela ukuchaphazela imbangela yokuqala yokufa kwesisu, kungekhona imiphumo yayo.
Iintlobo eziphambili ze-necrosis kunye nezizathu zokubonakala kwayo
Kwiyeza, kuyisiko ukukhetha i-necrosis yeeseli ngokwemiqathango ye-3.
Ngako oko, ezi zilandelayo zifom zesifo ziyabonakala:
- trophononeurotic;
- ischemic;
- i-allergenic;
- buhlungu;
- i-toxigic.
Indlela yokuphuhlisa ihlula i-necrosis ngqo, equka iindidi ezimbini zokugqibela zezifo ezivela kuloluhlu olukhankanywe ngasentla, kunye nolunye uhlobo oluchanekileyo lwe-pathology, olubandakanya zonke iifom.
Kukho ukwenziwa ngokwemiqathango kuxhomekeke kwizibonakaliso zekliniki zesifo kunye neempawu zayo zokuziphatha:
- Ebuhlungu;
- ukuhlasela kwentliziyo;
- i-coagulative okanye eyomile;
- fibrinodi;
- i ngqumbo;
- ukuxhoma;
- izilonda zoxinzelelo;
- idibene okanye imanzi;
- kulandelwa;
- amanqatha.
Uhlobo oluqhelekileyo lwe-necrosis yi-ischemic (i-vascular) ukufa kweethambo zenhliziyo - ukuhlaselwa kwentliziyo . Iifom ezisele zifunyenwe malunga nomlinganiselo ofanayo.
Isiphumo seentlobo eziphambili ze-necrosis kwizigaba ezahlukeneyo
Kukho imiphumo eninzi yenkqubo ekuqwalaselwa ngayo. Phakathi kwazo, kukho iinguqu ezi-7 eziphambili zekhosi yokukhubazeka, apho i-pregnination of pregnination is dependent:
- Ukutyunjwa - kukho ukwahlukana kweeseli ezifile, kunye nabo bajolise ekugxileni ngokutsha. Oku kuqinisekisa ukuhlukana kwezicubu ezinempilo kunye nezifo. Kwindawo echaphazelekayo kukho i-edema kunye nobomvu, ukunyuka kwegazi, okwenza i-leukocytes kunye ne-phagocytes zikhuphe iifelesi ezonakalisiweyo ngokuzimeleyo.
- Umbutho - ukutshintshwa kwezicubu ezifile kunye nebala. Emva kokupheliswa kwe-necrosis kwindawo yayo kukho inkohlakalo.
- Ukucaphulwa kwempahla - isayithi kunye neeseli ezifile zikhawulelwe kwi-capsule yezicubu ezinxibelelwano.
- Ukubalwa okanye ukunyusa ukuqina kancinci kwendawo enobungozi ngenxa yokuqokelela i-calcium isaliti kuyo (calcyphic calcification).
- I-ossification yindlela engavumelekanga yokuqhubeka nokubalwa, xa izicubu zethambo zivela kwisiza se-necrosis.
- I-Kistoobrazovanie - isiphumo sohlobo oluhambelana nesi sifo.
- Utywala luhlobo olubi kakhulu lweziphumo zesifo. Iintloko kunye nezicubu ezinamahloni ezincibilika phantsi kwezenzo zeenkqubo ezingenanto kunye ne- bacterium ye-pathogenic .
