Kutheni bayavuka okanye ubuza iiseli ezimhlophe zegazi count?

iiseli ezimhlophe zegazi ezi iqela leeseli ukuba zahluke umsebenzi imbonakalo. Bona luphawulwa kukungabikho umbala, kwakunye ebusweni core. iiseli ezimhlophe zegazi ziveliswa lomongo wethambo kunye zamanzi. Nangona kunjalo, indima yabo emzimbeni womntu liphezulu kakhulu. Ezi seli igazi kuvela kuzo umzimba kulawo iintsholongwane ezahlukeneyo, iintsholongwane, iintsholongwane kunye neeseli amazwe. Nangona kunjalo, ukuba umsebenzi kuphela ye enilinyatheleyo, kodwa nayo yathatha inxaxheba omzimba, ukuvelisa izilwa-buhlungu kunye ndilutshabalalise arhente Ukuhlanganisa ngolunya.

Ngokutsho kulwakhiwo lwalo zonke iiseli zegazi ezimhlophe egazini ziye nohlulwe granular kunye nezernistye. basophils, eosinophils, monocytes, neutrophils, lymphocyte: Ngokutsho zohlobo olufanayo kukho amaqela ezihlanu. Nganye kwezi ntlobo yi uzalisekisa ngokungqongqo umsebenzi wayo ethile. Umzekelo, basophils ziqulathe histamine kunye lweeHedfowuni, ukunceda umzimba bokulungisa negazi kunye nokudumba. Eosinophils kwi ezakheke arhente antihistamine. main umsebenzi wabo - ohlambululayo umzimba yibhaktheriya kunye kwamagciwane. Neutrophils fagotsintoz kwenziwe hayi kuphela kutshabalalisa iintsholongwane, kodwa imveliso zabo inkunkuma (ityhefu). Ngamanye amazwi, eli qela leukocytes eqhuba kweentsholongwane ephilayo. Manotsity kutshabalalisa amagciwane kunye ngeempahla zabo. Lymphocyte banoxanduva kwimveliso omzimba, ukwandisa ukuxhathisa komzimba xa iyonke.

Leukocytes equlethwe igazi isixa malunga 4-9 amawaka / ml. Ukuba ngexesha uhlalutyo ukutenxa inani afunyanwa, oku kubonisa ithi ezimbini: leukocytosis okanye leukopenia.

Leukocytosis yimeko apho legazi amhlophe sibale landa. Amaninzi oko kubonisa izifo ezihlasela zosulele (idla virus) okanye ukudumba. Nangona kunjalo, qaphela ukuba akukho mfuneko inqanaba eliphezulu leukocytes ithetha nasiphi na isifo, oko maxa wambi yokusabela enjalo utshintsho emzimbeni. Umzekelo, ukwandisa inani ukukhulelwa kunye ntshikilelo, emva neengxaki ngokwasemzimbeni kunye imithwalo, emva kokufumana ehomereni ke ngokugqithiseleyo eshushu okanye ebandayo, kwaye nkqu ngexesha premenstrual. Ukongeza, izinga iiseli zegazi ezimhlophe egazini abantwana liphezulu ngokubanzi ngaphezu koko abantu abadala. Kwaye ke uhlalutyo bonke zingenakukwazi ukuba zibe zezichanekileyo emva kokutya ukutya. Kungenxa yoko le nto kubaluleke kakhulu ukuba isiphumo ukuba uyithathele ingqalelo yonke imibandela.

Lokufunyaniswa leukopenia ukubeka abo iiseli ezimhlophe zegazi egazini zivunyelwe, nto leyo amanqaku mayinganxaxheli yehle nezifo. Leukopenia kungenzeka kanye njengoko ulwamkelo iziyobisi (anticonvulsants, analgesics, njl) Yaye zizifo ezahlukahlukeneyo viral (chicken pox, umkhuhlane, rubella, njl). Nezinye izinto ezibangela kuncitshiswa ngokuqulathwe leukocytes zingasebenza collagenosis, ukwenzakala kwemitha (radiation,-x reyi), izifo igazi, qhagamshelana ne imvelaphi into imichiza (iarseniki, benzene, DDT kunye nabanye.). Spleen izifo okanye ukusilela luvo okanye kophulwe imigaqo hemopoiesis, izifo ezithile ezidalwe kunye Ukudlulela yamathumba kwi umongo - sonke ezikhokelela leukopenia. Noko ke, akulula kunokubonwa kwinqanaba elisezantsi iiseli ezimhlophe zegazi kubantu abadala, okanye ediniwe nje.

Asimele silibale ukuba uhlahlelo igazi kubalwa ingundoqo nje kuphela kodwa amaxabiso relative okuqulethwe iintlobo ezahlukeneyo iiseli ezimhlophe zegazi. Ngaphezu koko, ukuba norm kudlulela ngaphaya ipesenti kuphela iindidi ezithile leukocytes, loo nto ithathwa inani lilonke, ukuba libe lichanekile, ngoko uhlalutyo ngokuqhelekileyo uthathwa okulungileyo. Ngenxa yoko, kuba sisalathisi nto kuthiwa ulwazi ngakumbi. Kuphela kule ebangela ukufumana umfanekiso jikelele yempilo.
