Zegazi: izinga kumadoda egazini

Zegazi - a iiseli non-nuclear semilo ungqukuva kunye ububanzi of microns 2-4 (micrometer). Ezi seli, ukongeza leukocytes neeplatelets ezi corpuscles igazi. Ewe kuthiwa ziiplatelets. Ubuninzi kwemithambo yegazi ziquka zegazi abaqolileyo - malunga ne 87% ye cell yabo endala - 4.5% kunye abatsha okanye ubuntwana - 3.2%. ixesha ekukhuleni zegazi-avareji ihlala iintsuku-8. Ngokuba egazini we-9 ukuya kowe-11 iintsuku ziiplatelets.

Ummiselo amadoda, abafazi kunye nabantwana ziya kwahluka kancinci. Ukongeza, ngokuxhomekeka kubudala yomntu iyatshintsha. Kuhlalutyo egazini jikelele kunye leucocytes, ihemoglobin, izinga erythrocyte neentlenge (ESR) kunye nefomula leukocytic iquka sisalathisi ezifana ziiplatelets. oyindoda oqhelekileyo ezi seli kukuba ukusuka 180 ukuya 400 yeebhiliyoni ilitha.

kumiswa phi na kutshatyalaliswa?

Zegazi kwakheka zeeseli amakhulu megakaryocytes, ezo zizaliswe phantse ngokupheleleyo kukho icytoplasm. Oku iiseli nyama- umongo wethambo. Emini, umzimba abunjwe zegazi ezintsha malunga 70 lamawaka - ziiplatelets. ngamaqhekeza amancinci megakaryocyte kukho icytoplasm bahlukane kwaye ufake egazini - ziiplatelets benziwa. Emva koko, ezi seli abaqolileyo, ukwenza imisebenzi yazo, yaye ngo-9-11 imihla bawatshabalalisa udakada. Eli ziko lijongene ngaphandle kwegazi kwakheka izakhi isakhiwo ezaphukileyo, ephezulu.

Enye megakaryocyte ukuze kwakheke phambi kokuba ziiplatelets 8000. Kuba uphuhliso iiseli lomongo wethambo emzimbeni ukuphendula hormone ethile - thrombopoietin, nto leyo kuhlelwe esibindini, zezintso, kunye umsipha skeletal. Ukusuka apho egazini oko kuya umongo wethambo ebomvu. Kwaye ilawula ukuyilwa megakaryocytes neeplatelets. Ngenxa yokwanda zegazi kwenzeka inhibition of Yindibanisela thrombopoietin hormone.

iipropati bokuphila

Zegazi zidlala indima ebalulekileyo nokomzimba. Ukuba enze le misebenzi ilandelayo:

• stop ukopha Initial.
• Ukugcina ithoni semithambo kunye permeability.
• basabela kukhuseleko.
• Kunye leukocytes inxaxheba ukuphelisa iinkqubo arhabaxa.
• Ukugcina igazi sikarhulumente engamanzi.

Kodwa abaninzi bavakalisa umsebenzi wabo hemostatic. Xa isitya igazi yonakele reflex ukuvala le mithambo. Zegazi ne collagen (coalescence zabo kwenzeka) kwaye ihlwili legazi ezikhandelwa ekhuthaza hemostasis.

Yintoni ichaphazela zegazi count?

Makhe sibone oko kuchaphazela sisalathisi ezifana ziiplatelets. Ummiselo amadoda engaphezulwana nje kancinane kunalowo kwabasetyhini kunye nabantwana. Ngamacala zegazi, phakathi kwezinye izinto, abantwana kunye nabantu abadala abachatshazelwa yi ubudala. Ngoko, kwi kuluhlu usana eqhelekileyo zegazi libanzi impela kwaye isusela ukusuka 100 ukuya 420 x 10 ⁹ / L (bn / l). Le ukwahluka ihlobene nenyaniso yokuba inkqubo yokujikeleza of kuzalwa iyahlozinga kakhulu neeplatelets, kwakunye nezinye iiseli ligazi, ukuphuhlisa inxaxheba baze bafe. Oku kuqhuba phezulu ukuya kunyaka.

Inani zegazi egazini abe jinga onyaka, ukwanda emva amandla kakhulu emzimbeni kwaye okunzulu ngemihla.

zegazi norm for amadoda, abafazi, abantwana

Yazi nge imithetho loo amadoda, abafazi kunye nabantwana ngokwakho, ngokuxhomekeke ubudala kule theyibhile ingezantsi.

Eminye imithombo lubonise ukuba izinga zegazi emadodeni ukuya ku-320 x 10 ⁹ / l. Yinto a bit data lixesha.

Zegazi: izinga emadodeni

Yehlisa ixabiso inokuba sex ngokomelela emva kweminyaka engama-60. Kuxhomekeka yobudala kwezinye yokuhlaziya jikelele yemida igazi zingatshintsha. Oku kukwasebenza kwisingqinisiso enjalo, njengoko neeplatelets. Ummiselo emadodeni abangaphezu kweminyaka yobudala eli eyesibini iparameter ayisebenzi umsebenzi kule theyibhile.

Ebudaleni, inani zegazi libe ezisezantsi kancinane. Le tafile ibonisa ngokucacileyo indlela kuyahlukana nedlela ubudala kwizalathisi ezikwinqanaba ziiplatelets. Ummiselo emadodeni engama-60 ubudala yehliswe kancane kuthelekiswa amanani abantu abatsha.

Ntoni kwenqanaba ziiplatelets?

Le Uhlalutyo jikelele legazi , kunye haemoglobin, leucocytes, umyinge neentlenge erythrocyte kunye leukocyte count sisalathisi esibalulekileyo, neeplatelets. amadoda Eqhelekileyo na egazini labo ukuya ku 400, abasetyhini - ukuya ku-380 x 10 ⁹ / l. Ukuba eli nani liphezulu kakhulu, ngoko imeko ekuthiwa thrombocytosis. Oku kunokubangela ekunqandeni yegazi eyonyukileyo. Kodwa ke oko akuthethi symptomatically kubonakaliswa. Kudla kutyhilwa ngengozi - ngelo xesha uvavanyo lwegazi jikelele ngexesha kuhlolwa. Thrombocytosis kunokwenzeka phantsi kwale miqathango ilandelayo:

• iinkqubo Oncological.
• Mielofiboz.
• iinkqubo Chronic arhabaxa.
• izifo ezosulelayo.
• Ithuba postoperative.
• Eritromiya (leukemia ezingapheliyo).
• Emva ukususwa udakada (splenectomy).
• Xa ayoni anemia.
• Ngenxa yokusebenzisa elide amayeza ezithile, ezifana corticosteroids.

Zonke ezi meko kunokubangela ukunyuka zesi salathisi, njengoko neeplatelets. Ummiselo egazini babantu zisoloko engaphezulwana nje kancinane kune kwabasetyhini kunye nabantwana. A ukunyuka okungephi kwi zegazi kunokwenzeka emva umthambo olunzulu. Oku ngezifo. Emva kokuba abanye, eli nani uza zibuyele esiqhelweni. Thrombocytosis lo zamabanga aphakamileyo.

Kubanga thrombocytosis Primary

Iziphumo thrombocytosis ephambili evela ukuphazamiseka of hematopoiesis (ukusekwa kunye ekukhuleni iiseli zegazi), iiseli stem umongo wethambo. Izizathu kungaba:

• Ezinye iintlobo kwegazi.
• Eritromiya.
• leukemia Chronic myeloid.
• yamehlo Fibrotic of lomongo wethambo (myelofibrosis).
• thrombocythemia Idiopathic, i zegazi count kufuneka kwandiswe ku 4,000.

Kubanga thrombocytosis Secondary

thrombocytosis Secondary ikhula ngenxa yeemeko zophendlo lwezifo (izifo) ukuba aziphazamise imizimba krovetvoritelnyh. Unobangela oqhelekileyo thrombocytosis zamabanga wosulelekile.

Izizathu ezinokwenzeka of thrombocytosis eziziisekondari:

• isifo samathambo.
• Rheumatism (igama echanekileyo yesi sifo - fever etsolo rheumatism).
• Osteomyelitis okanye inkqubo necrotic kwi umongo wethambo.
• okwenziwa sisilonda sikabhobhosi.
• izifo zesibindi ezimandundu, ezifana ukuqina.
• Tuberculosis.
• iinkqubo Neoplastic, umz, carcinoma, lymphoma okanye isifo Hodgkin kaThixo.
• ukopha amakhulu.
• hemolysis Acute (imeko kakhulu apho kuwohloka erythrocytes kwenzeka).

Yintoni zegazi low count?

Thrombocytopenia - yimeko apho zegazi uncipha. Ummiselo emadodeni kwezinye imithombo ekhoyo ukuya ku-320 billion iiseli ilitha nganye, ngexesha kwamanye - 400, kwaye esezantsi ebotshiwe nayiphi na imeko ukusukela kuma-180 cells. Ukunciphisa le nani izihlandlo eziliqela ziya kuqwalaselwa thrombocytopenia.

Izizathu kungaba:

• iinkqubo Infectious.
• ukungaqheleki olusebenzayo umongo wethambo.
• Ukukhulelwa kunye ndaba kwabasetyhini.
• Anaemia ezahlukahlukeneyo.
• Leukemias.
• Yofuzo.
• Imiphumo eyingozi enzima.
• Utywala kukuninzi.
• ukopha zikawonke.
• Ukuthatha iziyobisi ezithile (ezifana antibiotics, analgesics, estrogen).

Ukutenxa amaxabiso zegazi eqhelekileyo kuyo naliphi icala lufuna uviwo ngenyameko kunye nonyango kuphela iziyobisi, kodwa ngokunciphisa efanelekileyo.
