Kodi othandiza magazi kuundana? udindo wawo thupi ndi chiyani? Amene matenda othandiza magazi kuundana kuchuluka

Othandiza ang'ono sanali nyukiliya anapanga zinthu magazi. Iwo nawo hemostasis (a zovuta za zochita umalimbana wotseka magazi ndi chenjezo). Othandiza ndi kuzungulira kapena chowulungika mu mawonekedwe. The m'mimba mwake kwa maselo ndi awiri ndi anai microns.

Mu mitsempha ya magazi, maselo othandiza magazi kuundana imakonzedwa pa makoma kapena m'magazi. Ngati chachiwiri, maselo a boma wakhazikika ndipo ali chimbale mawonekedwe. kupatsidwa zinthu za m'mwazi kutsegula kumathandiza kusintha mtundu uliwonse: maselo kukhala sphericity ndi protuberances yeniyeni mawonekedwe (pseudopodia). Mwa njira imeneyi amatha zinthu magazi chotsatira mzake kapena kuti mpanda wa chotengera ndi kuwonongeka. zodabwitsazi amatchedwa loitanirana (kusagwirizana). Othandiza Komanso, adzalandira katundu kwa guluu wolimba ndi (cohesion), degranulation (amasulidwe zili), aumirira Anabweza (kapena kupatukana wathunthu cha kuchepa magazi aumirira ku seramu). Pamwamba pake, maselo amatha kulekerera fibrinogen, chinthu biologically yogwira (serotonin), anticoagulants, ndi maofesi m'thupi (kufalitsidwa).

Ndi guluu wolimba ndi kupatsidwa zinthu za m'mwazi loitanirana amapereka hemostasis m'zotengera ang'ono-likungosonyeza (maselo kudziunjikira pa malo kuwonongeka). Monga ogalamutsa coalescence ndondomeko ndi zikuwonjezereka masiku ano, thrombin, kolajeni, serotonin. Ndi nawo thrombin ndi njira mapangidwe (pseudopodia). Kupatsidwa zinthu za m'mwazi pellets muli clotting zinthu (serotonin, peroxidase enzyme kupatsidwa zinthu za m'mwazi fibrinogen, adenosine diphosphate (ADP), serotonin, kupatsidwa zinthu za m'mwazi-linachokera kukula chinthu, Von Willebrand chinthu).

Pa Anabweza wa magazi aumirira amapezeka guluu wolimba kuti Ulimbo filaments ndi kumasula trombostenina zomwe zikukhazikitsa pa iwo. Chifukwa chisindikizo ndi kupotoza ulusi, motero kupanga thrombus chachikulu.

Analysis wa othandiza magazi kuundana magazi kudziwa magawo coagulation. Akuti ndende wabwinobwino wa 180-320 zikwi pa milliliter.

Ngati maselo othandiza magazi kuundana ndi kuchuluka, ndiye pali thrombocytosis. Chotero chikhalidwe kungasonyeze matenda aakulu a chilengedwe, zotupa, matenda opatsirana magazi. Thrombocytosis zingachititse mapangidwe magazi kuundana mu ziwiya. Ngati maselo othandiza magazi kuundana ndi kuchuluka, n'zotheka thupi limafooka. Chotero chikhalidwe akhoza zidzayambike ndi kusanza, kuchepa madzimadzi madyedwe, chopondapo matenda.

The ndende ya maselo othandiza magazi kuundana m'magazi zingasiyane malingana ndi nyengo pa chaka, kapena tsiku. Kutsitsa zili selo zingaoneke mu msambo kapena mimba. Nthawi zambiri othandiza kuchuluka pambuyo zofuna kukhetsa thukuta.

Thrombocytosis angayambe akulu ndi ana omwe. Kuwonjezeka kupatsidwa zinthu za m'mwazi ndende akhoza kukhala yaikulu kapena sekondale.

Ana thrombocytosis pambuyo osati kuvutika kobadwa nako.

Poyamba kuchuluka othandiza magazi kuundana, amangoona pa eritremii, aakulu myeloid khansa ndi matenda ena magazi. Kuwonjezera ndende ya maselo magazi amagwirizana ndi mathamangitsidwe wa gulu la kalambulabwalo (megakaryocytes). Zimenezi ndi khalidwe kusinthika zilonda.

thrombocytosis Secondary wapezeka matenda akuwuka mwa kuchuluka kupanga thrombopoietin (polypeptide timadzi).

Othandiza akhoza ziwonjezeke mu anam'peza matenda a m'matumbo, TB m'mapapo mwanga, rheumatoid articular zotupa khalidwe extrapulmonary TB, amyloidosis, osteomyelitis, chiwindi matenda enaake ndi ena okhalitsa yotupa pathologies. Thrombocytosis limapezeka pa maziko a chitukuko cha zotupa zilonda, kukha magazi, pambuyo zopindika ena kubadwa.
