Platelets: te auau hoki nga tangata i roto i te toto

Platelets - he pūtau kore-karihi o te āhua porohita ki te diameter o 2-4 microns (micrometer). Enei pūtau, i roto i te tua ki leukocytes me platelets he corpuscles toto. Ko ratou i huaina platelets. Ko te nuinga o te bloodstream Kei platelets pakeke - e pā ana ki 87% o ratou pūtau tawhito - 4.5%, me te kuao teeki ranei - 3.2%. te wā matuatanga o platelets i runga i toharite pumau mo 8 ra. Ko ratou i roto i te bloodstream o 9 ki te 11 nga ra platelets.

Ko te täkupu e hoki nga tangata, wahine me te tamariki ka waiho paku rerekē. I tua atu, i runga i te tau o te tangata rānei e te huri hoki. I roto i te tātari toto whānui me leucocytes, pūtoto, auau ngeniwhero parataiao (ESR) , me te tātai leukocytic ngā he tohu pērā i platelets. tane Pūnoa enei pūtau he i 180 ki te 400 piriona i rita.

Hea e hanga e, ka ngaro?

Platelets e hanga e o ngā pūtau nui o megakaryocytes, e e tata katoa ki tonu i te cytoplasm. Tenei pūtau nui o wheua wheua. I roto i te ra, i hanga te tinana kei te pā ana ki 70 mano platelets hou - platelets. E wehea whatiwhatinga iti o te megakaryocyte cytoplasm me tomo te bloodstream - platelets i hanga. I muri, enei pūtau pakari, te kawe atu o ratou mahi, a i te 9-11 kei ngaro ra i roto i te kōateate. Tenei tinana te kawenga mo te whakarerenga o toto i hanga āhuatanga ki te hanganga whati, overage.

Ka taea te hanga e Kotahi megakaryocyte te aroaro o nga platelets 8000. Hoki te whanaketanga o ngā pūtau wheua wheua i roto i te tinana whakautu taiaki ngā - thrombopoietin, synthesized nei i roto i te ate, whatukuhu, me te uaua kōhiwi. Mai i reira i roto i te bloodstream tomo te reira i te hinu wheua wheua whero. A regulates reira te hanganga o megakaryocytes me platelets. Ki te hua i roto i platelets toto puta inhibition o ariā o thrombopoietin taiki.

āhuatanga whaiaroaro

Platelets tākaro he wāhi nui i roto i ngā tukanga whaiaroaro. mahi ratou i te mahi e whai ake nei:

• toto mutu tuatahi.
• Te whakaū i te āhua iaia me te uruhanga.
• tauhohenga paruru.
• Fakataha ki leukocytes whai wāhi i roto i te whakakore i ngā tukanga inflammatory.
• Te pupuri i te toto i roto i te āhua wai.

Otiia faaite te nuinga o ratou mahi hemostatic. A, no te pakaru he oko toto e pūpū whāiti te lumen. Platelets taunekeneke ki collagen (puta ratou coalescence) me te katinga toto i hanga e nei whakatairanga hemostasis.

He aha te pānga tatau te mōtepe?

Kia kitea tatou i roto i te mea pānga te tohu pērā i platelets. Ko te täkupu hoki nga tangata, ko te paku ki runga ake i taua o te wahine me te tamariki. I kaute mōtepe, i roto i era atu mea, i roto i rua tamariki me ngā pakeke pāngia e te tau. Ko te kupu, i roto i te noa whānuitanga fanau o platelets he tino whānui, me te pae i 100 ki te 420 x 10 ⁹ / L (Te Hokowhitu a / l). pā ana tēnei rerekētanga e ki te meka e te pūnaha circulatory o hou ko te tino iu me platelets, me ētahi atu pūtau toto, kaha whakawhanake ratou, ka mate. tonu ana tēnei ki runga ki te tau.

kia whai i te maha o platelets i roto i te toto hīrere wā, ka nui haere i muri i te itoito tinana kaha, me te whai rerekē rā.

täkupu mōtepe mō tangata, wahine, tamariki

A haamatau ia outou ki te ture o taua o nga tangata, wahine me te tamariki, i runga i tau kei taea e i roto i te ripanga i raro nei.

tohu ētahi puna e te tere o te mōtepe i roto i nga tangata ki runga ki te 320 x 10 ⁹ / l. Ko te he raraunga tawhito moka.

Platelets: te auau i roto i nga tangata

kia tukua iho te uara i roto i te sex kaha i muri i te 60 tau. Tei runga i te tau o etahi o te tātari whānui o ngā tawhā toto kia huri. E pā ana hoki tēnei ki te mehua taua, kia rite ki platelets. tohua te täkupu i roto i nga tangata i runga i te tau o tenei tawhā e i roto i te tepu.

I roto i te pakeketanga, kia meinga te tokomaha o platelets paku raro. mārama E whakaatu ana tēnei ripanga pehea rerekē i runga i te tau o te tohu auau rite platelets. Ko te täkupu i roto i nga tangata kei te paku iti 60 tau o te tau whakaritea ki te uara o te iwi taitamariki.

He aha e te taumata nui ake o platelets?

Ko te tātari whānui o toto , me ki pūtoto, leucocytes, ngeniwhero auau parataiao me te tatau leukocyte ko te tohu nui, me platelets. tangata Pūnoa i roto i to ratou toto ki runga ki te 400, wahine - ki runga ki te 380 x 10 ⁹ / l. Ki te he nui teitei tenei ahua, ka karangatia e te huru thrombocytosis. Tenei e taea meinga nui ake upoo- toto. Otiia e kore e reira symptomatically whakakitea. E mea pinepine whakakitea rawa i te aituā - i te wa he whakamātautau toto whānui i roto i te tirohanga ngā. Ka taea e Thrombocytosis puta i raro i nga tikanga e whai ake nei:

• tukanga Oncological.
• Mielofiboz.
• ngā tukanga inflammatory ma'i.
• mate hopuhopu.
• Ko te wā postoperative.
• Eritromiya (kanisā ma'i).
• I muri i tango o te kōateate (splenectomy).
• A, no te rino hē anemia.
• Ka rite ki te hua o te whakamahi roa o etahi rongoā, pērā i corticosteroids.

Ka taea e te katoa o enei tikanga meinga te hua o tenei tohu, kia rite ki platelets. Ko te täkupu i roto i te toto o nga tangata e te nuinga o ratou paku ki runga ake i roto i nga wahine, me ngā tamariki. He hua iti i roto i taea i muri i mahi kaha mōtepe. e kore te mea he māuiuitanga tenei. I muri i te okiokinga, tenei ahua mai hoki ki noa. He tuatahi, me te tuarua Thrombocytosis.

Take thrombocytosis Paraimere

Ko te hua thrombocytosis tuatahi i disorders o hematopoiesis (hanganga me te matuatanga o ngā pūtau toto), wheua wheua pūtau kakau. Ko te take i taea e:

• Ētahi momo o anemia.
• Eritromiya.
• Ma'i kanisā myeloid.
• e hōloa Fibrotic o wheua wheua (myelofibrosis).
• thrombocythemia Idiopathic, kia nui haere te tatau mōtepe ki 4.000.

Take thrombocytosis Tuarua

whakawhanake thrombocytosis Tuarua rite ki te hua o ngā āhuatanga pathological (mate) e faanane tinana krovetvoritelnyh. Ko te take tino noa o te thrombocytosis tuarua ko te mate.

take pea o thrombocytosis tuarua:

• kaikōiwi.
• Rūmātiki (te ingoa tika mō tenei mate - whakapeka rūmātiki).
• Te tapû-tukanga necrotic ranei i roto i te hinu wheua wheua.
• colitis ulcerative.
• mate ate kino, pērā i cirrhosis.
• Mate kohi.
• tukanga Neoplastic, hei tauira, mate pukupuku, lymphoma mate a Hodgkin ranei.
• mate toto nui.
• hemolysis whakapeka (huru nui i roto i nei te pirau o erythrocytes puta).

He aha e tatau mōtepe iti?

Thrombocytopenia - he huru i roto i nei e heke platelets toto. Ko te täkupu i roto i nga tangata i roto i te tahi mau puna e wātea ana ki runga ki te 320 piriona pūtau ia rita, i roto i etahi atu - 400, me te rohe raro i roto i tetahi take mai i 180 pūtau. Whakaiti i tenei ahua, ko te ka rave rahi taime e whakaaro thrombocytopenia.

pea te take:

• tukanga hopuhopu.
• abnormalities Taumahi o te hinu wheua wheua.
• Pregnancy me te paheketanga i roto i nga wahine.
• Anemia o ngā momo.
• Leukemias.
• Whakapapa.
• Ko te pānga kino o konganuku taimaha.
• Waipiro i roto i ngā rahinga nui.
• toto nui.
• Tango etahi taero (pērā i paturopi, Pë, estrogens).

Ine i ngā uara mōtepe noa i roto i rānei aronga titau whakamātautau tupato, me te maimoatanga o te raau taero e kore anake, engari ano hoki he kai e tika ana.
