Kuthetha umthamo corpuscular wawisa: Oonobangela

Iiseli zahlulwe zibe zokuzikhusela zokuhamba. Ukuze ufake isicelo i emhlophe zokhuselo iiseli zegazi neeplatelets. Ukuze zokuthutha erythrocytes.

Yintoni na iiseli ezibomvu zegazi

Iiseli ezibomvu - a ebomvu legazi. Umsebenzi main benza umsebenzi, - ukuthuthwa iigesi igazi (carbon dioxide neoksijini) ye ancedisana emiphungeni kunye umva.

Ukuvavanya imeko ezi seli kumisela ezinye iparameters rhoqo. Ezi ziquka igazi elibomvu cell count, umthamo erythrocyte, ubungakanani kunye nemilo.

Inani iiseli ezibomvu wayezimisele kuvavanyo egazini jikelele. Ubukhulu kunye nokumila iiseli - on iimviwo ngemikroskopu mvavanyo igazi. A ukuthini corpuscular umthamo futhi umthamo xi tiyimisele kuphela phantsi uphando olulodwa. Ngokusekelwe kwezi data Sigwetywa ngokobunjani ezisebenzayo.

Kwezinye izifo zingatshintsha ezahlukeneyo parameters ezi seli.

Kwenzeka njani ukuba ukujonga umthamo athetha corpuscular? Ukulungiselela le njongo, kukho eyandisiweyo segazi, apho umthamo kungabonwa kunye iseli enye.

Uhlolisiso iiseli ezibomvu zegazi

Ukubekwa umthamo yeseli koko kwenziwa lwekhompuyutha zemathematika. Isalathisi ibanjiwe ngokwahlula-hlula hematocrit yi-avareji yenani iiseli ezibomvu zegazi.

Esi salathisi idlala indima ebalulekileyo lokufunyaniswa kwegazi kunye nokutshintsha ebomvu zobungakanani legazi, nto leyo ekhokelela ukuba kwabo phansi kunye nomonakalo nokomzimba. Kule meko, kukho uphuhliso efanelekileyo yesikolo ngasinye komfanekiso kwezonyango sifo.

Ireyithi eqhelekileyo kuthathwa ukuba umthamo malunga 90 femtolitrov. Ukwanda kwenani waphawula kuphuhliso anemia macrocytic. Ukunciphisa isixa zikhokelela kuphuhliso microspherocytosis mikrotsetarnoy anemia. Ezi seli ezibomvu igazi ngokukhawuleza kufa ngenxa kwabo phansi.

Umthamo avareji iiseli ezibomvu kuyehla xa ezi zifo. Oku kwabangela ukuba ukungabikho kwezinye izondlo ezifunekayo ukuze zikhule kunye nophuhliso iiseli ezibomvu zegazi.

anaemia

Njengoko kukhankanyiwe, izifo eziziintloko kuncitshiswa umthamo kuthetha corpuscular, ukuba igazi. Bonke ayashiyana ukunqongophala kwezinto ezithile, nto leyo ebangela ukuba kusekwe engachanekanga iiseli ezibomvu zegazi, ke ngoko, kwekhono zabo. Kuye ekhankanywe apha ngasentla ukuba iiseli ezibomvu - a elements zothutho enkulu igazi, oko kukuthi, indawo yokuqala kungaphazamiseka unikezelo oksijini carbon dioxide wotshintshiselwano kunye ...

Yaba iintlobo enjalo kwegazi, ezifana nesinyithi, igazi sideroblasticheskaya, thalassemia. Zonke ezi zifo, xa ukunikezelwa mbilini ukhathalelo lwempilo, kungakhokelela ekubeni ukunyhashwa ezibalulekileyo kwicala zonke iinkqubo kunye nezigqeba isigulane. inxaxheba kangangoko kule nkqubo zophendlo lwezifo kunye nezinye izinto ze hematopoiesis.

Ukujongana nale ngxaki ikakhulu zegazi kulo, nangona uxilongo ephambili yezi zifo kufuneka kwenziwa zeetheraphisti zezithili.

Ngenxa yoko asakhasayo data-imibala anemia, yaye ziziphi iinkalo mava ngamnye kubo? Kutheni Kwenzeka ukuba lo mqulu koko corpuscular uvikivwa?

Anaemia ezinxulumene ukunqongophala yentsimbi egazini

Eyona ixhaphakileyo anemia ayoni. Olu hlobo leengxaki ibangwa ukuphazamiseka mpilo amagama - protein zezithuthi eziqulathwe erythrocytes. Le molecule inoxanduva nomphetho owujikelezileyo ioksijini bephefumla emiphungeni kunye nezothutho wayo emzimbeni.

Iron nguye ion ezinkulu, kuyimfuneko ekwakheni zinemoletyhule mpilo. Xa ayanelanga ukuba imbuyekezo kwimfuno ioksijini, umzimba uqalisa ukuvelisa erythrocytes ezincinane (m. Umsebenzi E. Umgangatho linani kufakwe leseli).

Yonke idatha ngaphantsi kwe iiseli eziqhelekileyo abomvu ubukhulu. Ngako oko, umthamo koko corpuscular uvikivwa kwisisele ngasinye. izinto ezinjalo ukunika ngokupheleleyo nezihlunu mpilo, nto leyo evusa umfanekiso ethile lwezonyango.

Ngaphandle kokuba iiseli ezibomvu zegazi benziwa emincinane kakhulu kunaleyo kufuneka, inani uhlala kwi kumqolo yesiqhelo. Ayajika kwaye kakubi elula zonke iintlobo zingentla kwegazi.

thalassemia

Thalassemia i sisifo yemizila yemfuza, nto leyo ekhokelela ukuba Yindibanisela hemoglobins ezingaqhelekanga. Kukho degrees ezintathu nobungozi besi sifo - inobulali, aphakathi kunye kakhulu.

Kule sifo kuguquka point inempembelelo ebalulekileyo isakhiwo yonke kwemolekyuli mpilo. Ngenxa ye yemfuza chain haemoglobin ukungasebenzi stop kuyilwa, apho kuba ayilunganga. athwala okunjalo ayisekho ukwimeko oluzinzileyo, nto leyo ke ithetha ntoni? Erythrocytes ethwele zinemoletyhule enjalo ayikwazanga ukuba elide egazini. Hemolysis iphuhlisa kwabo, nto leyo ekhokelela ekubeni ukugxagxiseka okubalulekileyo imeko yomguli kunye nokuphuhlisa nokothuka.

Ngenxa yokuba bukwavelise haemoglobin njengesonakeleyo, iseli ebomvu igazi ayikwazi kuba ngathi ufuna. Ngenxa yoku, kwaye kunciphisa umthamo iiseli ezibomvu, kukho uphazamiseko umsebenzi zothutho.

Esi sifo kuqhelekile kakhulu, nto leyo esinye sezizathu eziphambili ezibangela ukuba nokunciphisa umthamo iiseli ezibomvu zegazi.

Sideroblasticheskaya anaemia

Le meko lubonakala ngokuba ukuswela vitamin _B6, ehamba ngenxa apho haemoglobin esinesiphene ku kwaphula neenkqubo zokwenziwa. Xa molecule protein elinikiweyo proporfirinov coproporphyrins ayanelanga. Ngenxa yale ioksijini zokuphazamiseka ndibopha erythrocytes kunye nomthamo wabo kunciphisa.

Ngenxa ezingafanelekanga njini siphene baqale erythroblasts kunye nokwanda yentsimbi kwi kwiseli kukho icytoplasm. Ngokweliso iiseli enjalo neemicroscope azimisele ngokohlobo erythroblasts kunye inclusions cytoplasmic.

Ngenxa kuyondelelaniswe ezinesiphene iiseli ezibomvu ukuphuhlisa kwiklinikhi kakhulu anemia. iiseli ezineziphene abomvu phantse musa ukufeza umsebenzi zothutho, nto leyo ekhokelela kwingxaki kunaniselwano kunye nobomi yonke eziphilayo. ke ayohlulwanga Inani iiseli ezibomvu zegazi kwesi sifo, kodwa ngokukhawuleza kufa.

Isifo ifuna ngoncedo ezingxamisekileyo kunye nonyango olufanelekileyo. E ngaphambi ukunceda kunokwenzeka obulalayo.
