Zegazi esinyusiweyo - luphawu, nto kubalulekile ukunikela ingqalelo

Kwiimeko ezininzi, inkqubo naluphi na uviwo kwilebhu umguli kunye nesifo phantse naliphi na iqumrhu okanye inkqubo yomzimba luqala phezu abulawe uvavanyo lwegazi lwezonyango. Kweli phepha sifunda cellular ukwakhiwa igazi, ngokunjalo ukufunda iimpawu zezi zinto cellular. Oko utshintsho kwinkqubo hematopoietic, kukho ekhule yaye omnye Imiqondiso yokuqala ezayo iingxaki, kwaye ke iziphumo zeemvavanyo kwegazi zonyango ikwazi ukubona utshintsho enye, ezimbini okanye ezintathu iintsholongwane igazi-sisenziwa, ngoko ke kufuneka ukuba uhlawule ingqalelo zombini imadlana kunye zegazi anda, iiseli ezimhlophe okanye erythrocytes.

Ukutshintsha inani zegazi - isizathu ukuba kulondolozwe

Xa abantu, neeplatelets babe umsebenzi obalulekileyo - iiseli ezingenambala abanenxaxheba ngokuthe ngqo kwinkqubo coagulation igazi, ngokulandelelana, kunye notshintsho inani ezi seli kukhokelela ezingaqhelekanga kwinkqubo coagulation igazi. zegazi ophakamileyo, kungakhathaliseki ukuba unobangela wale meko ibe ngunobangela thrombus ukwakhiwa, kanti kubekho inani ezi seli oonobangela ukopha okanye legazi phantsi kwesikhumba. Amaxabiso eqhelekileyo izigulane abadala zithathwa zegazi peripheral kwi kuluhlu i-180-320 * 109 / L, ngelixa abantwana, ingakumbi kwixesha lweentsana kunye lwabantwana abasaqalayo (iminyaka do3) kuhlalutyo lwezonyango igazi phantse lonke ziiplatelets povyshenny.

Alithandabuzeki elokuba, uninzi lwezigulane abachaphazelekayo malunga nokuhla elibukhali kwi zegazi libalulekile ngezantsi kobudala, nangona kunye thrombocytopenia neziphumo ezibalulekileyo kakhulu ukuba eziphilayo yaphuhliswa ukuwa inani labo ngezantsi-20 * 109 / L, yaye phantse engazange agule ukuba awuzukhathalelanga ziiplatelets landa. Izizathu ukwimeko enjalo ingaba ngokwabo ezahlukeneyo - ukusuka imbonakalo amahlwili egazi komzimba ngabasebenzi ngokugqithisileyo ulwelo ngesikhumba okanye isifo wamathumbu okanye iphecana yokuphefumla, umz, ngemini eshushu okanye kukuvela ukuphazamiseka isisu, njengoko amathuba xa zegazi eziphakamileyo iimpawu zezifo zomzimba.

zegazi iphakamileyo ukubalwa uphawu izifo

Kwiimeko ezininzi, zegazi ephakamileyo ezinokuvela ngezifo ezinomongo wethambo hematopoiesis, apho babonakale uphawu njengokuba izitshanguba ze zegazi kuphela intsholongwane kwaye sisilonda esidumbileyoesingaphakathi lilonke umongo wethambo, umzekelo kuphuhliso ukuphazamiseka myeloproliferative (leukemia ezingapheliyo, myelodysplasia, mieloze subleukemic).

Yobeka phi ephakamileyo zegazi count kwenzeka emva ukuhlinzwa, apho, kuba udakada nokuba kungasiphi na isizathu, kufuneka zisuswe - umzekelo, xa kwentlungu, nangezilonda okanye izifo apho amanqanaba zegazi lehla kancinci, kunye nokususwa kwe udakada yaba ukusebenza lithemba. Ukunyuka zegazi count kule meko kuba udakada kwiimeko eziqhelekileyo uba "yamangcwaba" ezi seli igazi, esibindini ubukhulu wokusindisa enkulu erythrocytes kwenzeka.

kunqabile kakhulu, ukwanda platelets iimpawu ezithile izifo egazini, kodwa oku kuza thrombocytosis ikhawuleza kakhulu kwaye kungabonwa kuphela xa uhlalutyo isampuli ejikelezayo ngexesha ukusasazeka esebenzayo yentsholongwane emzimbeni.

Thrombocytosis. Ingaba kufuneka uhlonele kuyo?

Kwiimeko ezininzi, ukuze aphathe eziphezulu zegazi count kuyimfuneko kuphela xa ukwanda lwabo ngesiquphe, nto leyo esongela uphuhliso thrombosis. Ukuze isigqibo kwimeko nganye ethile oko kuyimfuneko ukuqhuba esweni olutshintshayo Ipharamitha yegazi lwezonyango, ngokunjalo kwi thrombocytosis progression, wenza okuhlatywa biopsy sternal kunye iphiko ilium. iimviwo lomongo wethambo kunye nesifundo amathambo kunceda ukuqonda - nokuba ubalo ukhetho norm eliphezulu zegazi ukusebenza komzimba okanye uphawu yokuqala isifo esiyingozi.
