Vim muaj ntau yam kab mob ntsws, sab nrauv lossis sab hauv, cov nqaij ntawm lub cev muaj peev xwm nkag mus tsis tau kev hloov thiab tuag taus. Nws yuav tsis ua tau kom rov tuag hlwb, tab sis nws yog ua tau kom tsis txhob muaj txoj kev no, limiting nws faib. Rau txoj kev kho mob yog tsim nyog kom paub txhua yam ntawm cov necrosis, txij li qhov sib txawv ntawm qhov kev ntsuam xyuas pub rau feem xyuam rau txoj kev tsim nyog ntawm cov nqaij mos, thiab tsis yog nws lub txim.
Lub ntsiab ntawm necrosis thiab qhov ua rau nws zoo li
Hauv cov tshuaj, nws yog kev cai lij choj los cais cov necrosis ntawm cov hlwb raws li cov txheej xwm 3.
Raws li, cov nram qab no cov ntaub ntawv ntawm tus kab mob no txawv:
- trophononeurotic;
- ischemic;
- tsis haum;
- kev puas ntsoog;
- toxigenic.
Lub tswv yim ntawm kev txhim kho yog qhov sib txawv ntawm cov necrosis, uas yog muaj ob hom kab mob ntawm cov kab mob saum toj no, thiab ib hom kab mob pathology, uas muaj tag nrho lwm cov ntawv.
Muaj kuj yog ib qho kev cais tawm nyob ntawm seb qhov tshwm sim ntawm tus kab mob thiab nws cov yam ntxwv ntawm cov yam ntxwv:
- Caseous;
- plawv nres;
- coagulative lossis qhuav;
- fibrinoid;
- gangrene;
- puas;
- siab qhov ntswg;
- colliquated los ntub dej;
- kev sib tw;
- rog.
Hom mob necrosis uas nquag feem ntau yog ischemic (vascular) tuag ntawm lub plawv daim tawv nqaij - lub plawv nres . Cov ntawv ntxiv uas pom muaj nyob hauv kwv yees li qhov sib npaug qub.
Cov txiaj ntsig ntawm cov hom mob necrosis hauv ntau theem
Muaj ntau heev ntawm cov txheej txheem ntawm tus txheej txheem nyob rau hauv kev saib xyuas. Ntawm lawv, muaj 7 tus kab txawv loj ntawm cov kev kawm ntawm pathology, uas nws qhov kev paub ua ntej yog nyob ntawm:
- Demarcation - muaj ib qho tawg tsam ntawm cov tuag lub hlwb, thiab nyob ib ncig ntawm lawv ua kom pom tseeb ntawm cov mob npau taws. Qhov no ua rau kev sib cais ntawm kev noj qab nyob zoo thiab mob cov nqaij. Hauv thaj chaw uas muaj kev puas tsuaj muaj kev kho thiab redness, ntau ntxiv ntshav, uas tso cai rau leukocytes thiab phagocytes rau nws tus kheej tshem tawm cov hlwb puas.
- Lub koom haum - hloov cov ntaub so ntswg nrog ib qho caws pliav. Tom qab txiav ib lub necrosis ntawm nws qhov chaw nws muaj qhov caws pliav.
- Encapsulation - ib qhov chaw uas muaj hlwb tuag rau ib lub khob tshuaj ntsaws.
- Calcification lossis petrification yog qhov sib sib zog nqus ntawm thaj chaw hauv thaj tsam ntawm cov kab mob necrotic vim qhov txuam nrog calcium ntsev hauv nws (dystrophic calcification).
- Ossification yog ib qho kev xaiv tsis tshua zoo rau kev ua haujlwm ntxiv, thaum pob txha pob txha tshwm rau ntawm qhov chaw ntawm necrosis.
- Kistoobrazovanie - qhov tshwm sim ntawm colliquative daim ntawv ntawm tus kab mob.
- Meltdown yog feem ntau hom tshuaj tiv thaiv ntawm tus kab mob. Lub hearth nrog cov ntaub so ntswg necrotic melts nyob rau hauv qhov kev txiav txim ntawm purulent kev thiab pathogenic kab mob .
