Abantu abangekho kumayeza, xa bebazali kwaye bajamelana neengxaki zokuqala ngempilo yengane yabo, bahlala bezibuza ukuba bangazihlaziya ngokuzimeleyo njani iziphumo zeemvavanyo ngokwabo ngaphandle kooncedo lwabagqirha. Ingcinci encinci kunoma iyiphi i-encyclopedia yezonyango, ulwazi oluyimfuneko lunokufumaneka. Enyanisweni, ngolwimi aluhlali luqondwa ngumntu olula. Masizame ukuqonda iziphumo zokuhlolwa kwegazi usebenzisa umzekelo we-monocytes.
Ngoko, i-monocytes iiseli zegazi, enye yeentlobo ze-leukocytes - abakhuseli abaziintloko bamasosha omzimba. Xa kuthelekiswa nezinye iiseli, nazo ziyi-leukocytes, i-monocytes zikhulu kakhulu kwaye zininzi kakhulu.
Ifomu leMonocytes kwisalathisi lesithambo, kwaye emva kokuvuthwa kwabo bangena kwinkqubo yejikelezayo, apho bahlala khona malunga neentsuku ezintathu, ke bawela ngqo kwiinqununu zomzimba, kwintlone, i-lymph nodes, isibindi, umongo wethambo. Apha ziguqulwa zibe yi-macrophages - iiseli eziseduze ne-monocytes ngomsebenzi wazo.
Benza umsebenzi wokuqala wamacwecwe emzimbeni, ukuxhamla iiseli ezifile, ii-microorganisms ze-pathogenic, ukukhuthaza i-cloor clots resorption nokukhusela izicubu ekuphuhliseni. I-Monocytes inokutshabalalisa izifo eziphilayo ezinkulu kunokuba zikhulu. Kodwa i-monocytes ibonisa umsebenzi omkhulu kunabo bonke xa besengumntwana kwi-circulatory system.
I-Monocytes iyingxenye ebalulekileyo yegazi, bobabini abadala kunye nabantwana. Benza imisebenzi eyahlukeneyo emzimbeni womntwana. I-Monocytes ibandakanyeka kwimveliso yegazi, ikhusele kwiindawo ezahlukeneyo ze-neoplasms, zokuqala ukuma ngokumelene neentsholongwane, i-microbes, iipasasiti ezahlukeneyo.
Isiqhelo se-monocytes kubantwana
Isiqhelo se-monocytes ebantwaneni sihluke kwiimeko eziqhelekileyo kumntu omdala kwaye akusiyo rhoqo, kodwa kuxhomekeke ngqo kwiminyaka yomntwana. Ngaloo ndlela, ngexesha lokuzalwa, isiqhelo sisuka kwi-3% ukuya kwi-12%, ukuya kunyaka ukusuka kwi-4% ukuya kwi-10%, ukususela kunyaka omnye ukuya kwiminyaka elishumi elinesihlanu, ukususela kwi-3% ukuya kwi-9%. Xa umntu omdala, inani le-monocytes ayifanele lidlule i-8%, kodwa ingabi ngaphantsi kwe-1%.
Ukuba izinga le-monocytes egazini lomntwana liyancitshiswa okanye ngokuphambene, koko kuyimfuneko ukuqhuba uphando ukuze ufumane izizathu zokuphambuka kwesi siqhelo.
Ukwanda kwama-monocytes kubantwana kuthiwa i-monocytosis. Kwenzeka, njengomthetho, ngexesha lesifo esithathelwanayo. Kwaye kungabonakalisa i-brucellosis, i-toxoplasmosis, i-mononucleosis, isifo sofuba, izifo zefungal.
I-monocytes ephakamileyo ngokukhawuleza kumntwana inokubangelwa yimiphunga emibi kwi-lymphatic system. Kwiimeko ezininzi, izinga labo lihle kwaye emva kokusuleleka.
I-Monocytosis ingaba nexabiso - xa ipesenteji ze-monocytes ziphezulu kunezinye eziqhelekileyo, kodwa ngokubanzi inani lamaseli egazi ezimhlophe lihlala liqhelekileyo. Isizathu siyancipha kwinani lezinye iintlobo ze-leukocyte. I-monocytosis engapheliyo ingenzeka xa inani leeseli ze-phagocyte kunye ne-macrophages landa.
I-monocytes eyanciphekileyo egazini kumntwana kuthiwa i-monocytopenia, kwaye, njengokuba i-monocytosis, ixhomekeke ngqo kwiminyaka yomntwana. Izizathu ezikhokelela ekunciphiseni kwi-monocytes zingaba ngolu hlobo:
- izifo zesifo somongo ngenxa ye-chemotherapy;
- emva kokuhlinzwa;
- ukwehla ngokubanzi kuzo zonke iiseli zegazi ngenxa yezifo ezahlukahlukeneyo zegazi, ezifana ne-aplastic anemia, umkhuhlane we-typhoid;
- Ukusetyenziswa kwexesha elide lamarmone;
- ukugqithwa ngokubanzi komzimba;
- kunye neenkqubo ezihlambulukileyo emzimbeni.
Ukuba umntwana wakho wehlise okanye waphakamisa i-monocytes egazini, kufuneka ufumane uviwo olongezelelweyo olunzulu ukuze ufumane isizathu.
