A: Ama-leukocyte, ikakhulukazi ama-neutrophils nama-macrophage, adlala indima ebalulekile ekuvuvukeni kwamaselula Lawa maseli akhangwa indawo evuvukele ngama-chemotactic gradients futhi anesibopho sokuqeda i-phagocytosing kanye nokucekela phansi amagciwane namaselula. Aphinde akhulule amakhemikhali akhulisa noma alawule impendulo yokuvuvukala.

Q: Imiphi imiphumela engaba nayo ukuvuvukala kwamaselula isikhathi eside?
A: Ukuvuvukala kwamangqamuzana okungapheli kungaholela ekulimaleni kwezicubu futhi kukhuthaze ukuthuthukiswa kwezifo ezingapheli, njenge-arthritis ye-rheumatoid, izifo zenhliziyo, izifo ezingapheli ze-pulmonary obstructive, izifo ze-neurodeergenerative kanye nezinye izinhlobo zomdlavuza.

Umbuzo: Kungelashwa kanjani ukuvuvukala kwamaselula?
A: Ukwelashwa kokuvuvukala kwamangqamuzana kuncike kumbangela ewumsuka. ⁤Lokhu kuhlanganisa ukusetshenziswa kwezidakamizwa ezingezona ukuvuvukala, i-corticosteroids, imishanguzo evimbela ukuvuvukala, kanye nemithi ⁤ehlosiwe eqondile. Ukwelashwa ngokomzimba kanye nokwamukela indlela yokuphila enempilo nakho kungasiza ekunciphiseni ukuvuvukala. Kubalulekile ukuthintana nochwepheshe bezempilo ukuze uthole ukuxilongwa okufanele kanye nohlelo lokwelapha.

Ekuphetheni

Kafushane, i-pathophysiology ⁢ukuvuvukala kwamaselula⁤ inqubo eyinkimbinkimbi ebandakanya uchungechunge lwezehlakalo zamangqamuzana namaselula. Njengoba sifunda kabanzi mayelana nezinqubo eziyisisekelo kanye nezindlela zokubonisa ezihilelekile, umnyango uvula amasu amasha okwelapha okwelapha izifo ezivuthayo. Kubalulekile ukukhumbula ukuthi ukuvuvukala kwamaselula kuyimpendulo yemvelo yamasosha omzimba, futhi ukuhoxiswa kwawo kungaba nemiphumela emibi empilweni. Kodwa-ke, ngocwaningo lwesikhathi esizayo, singathemba ukuthola izinhloso ezintsha zokwelapha kanye nezindlela ezisebenza kahle zokushintsha ukuvuvukala kwamaselula nokuthuthukisa izinga lempilo yeziguli.
