Platelets: o ka uku no na kanaka i loko o ke koko

Platelets - he pili-nukelea keena o spherical kinona me ke anawaena o ka 2-4 microns (micrometer). Mau keena, ma ka hou ana i leukocytes a me platelets i ke koko corpuscles. Ka mea, i kapaʻia platelets. Ke bulk o ke koko hoʻohui pū oo platelets - ma kahi o 87% o ko lākou kahiko aeea - 4.5% a me ka poe hou a me kaʻiliahi - 3.2%. ka maturation au o platelets ma ka awelika mau no ka 8 lā. Ka mea, i loko o ke koko o ka 9 a hiki i 11 mau lā platelets.

Ke kūmau no na kanaka, na wahine a me na keiki e e ikiʻokoʻa. Eia hou, ke kaumaha ma muli o ka makahiki o ke kanaka ua hoi hoʻololi. I mau koko Ka Ikepili a me leucocytes, hemoglobin, erythrocyte sedimentation uku (ESR) a me ka leukocytic haʻilula ka loaʻa o ka anakahi e like me platelets. Normal kāne i kēia mau aeee mea mai ka 180 a hiki i 400 ieeeea? Ma ka hano.

Hea e hana, a luku iho la ia?

Platelets i hanaʻia o ka nui keena o megakaryocytes, a i piha aneane loa me ka cytoplasm. Kēia kanaka nunui keena o ka iwi ka lolo. Iloko o ka lā, i ke kino ua hanaʻia ma kahi o 70 tausani hou platelets - platelets. Small koena o ka megakaryocyte cytoplasm i hoʻokaʻawaleʻia, a komo i ke koko - hana platelets. A laila, i kēia mau keena oʻo, e lawe mai i ko lakou mau oihana, a ma ka 9-11 e luku lā i loko o ka spleen. Keia kino He kuleana no ka loa o ke koko i hanaʻia nā kumumea me ka pepe 'ole, overage.

Kekahi megakaryocyte hiki ke hanaʻia ma mua o ka 8000 platelets. No ka hooulu ana o ka iwi lolo aeee i loko o ke kino pane mau hōmona - thrombopoietin, i ua synthesized ma ke akepaʻa, hakuʻala, a me skeletal Muscle. Mai laila ma ke koko ka mea, komo ka ula iwi lolo. A ia regulates ke kahua o megakaryocytes a me platelets. Me ka hoomahuahua i loko o ke koko platelets ia lŘlŘ inhibition o ka hoʻololi kemikala o thrombopoietin hōmona.

physiological waiwai

Platelets pāʻani nui i kūlana ma physiological keʻano o ka hanaʻana. Ka mea hana i ka kēia mau hana:

• Ka loiloi mua ana, kahe ana ke koko.
• Malama ana vascular leo a me ka permeability.
• Aiiay naoh.
• Together me leukocytes komo i loko o ke kāpaeʻana hoʻoʻino keʻano o ka hanaʻana.
• Malama ana i ke koko i loko o ka kinowai moku'āina.

Akā, kāheaʻia ka hapanui o lākou hemostatic kuleana pili i. A i kekahi koko moku ua poino reflex hou i ka lumen. Platelets interacting me ka collagen (lākou coalescence ia lŘlŘ) a me kekahi koko clot ua hana i paipai 'ia ka hemostasis.

He aha e loli ai ka platelet helu?

E loaʻa iā mākou mai mea e loli ai ka anakahi e like me platelets. Ke kūmau no ka na kanaka mea iki oi aku ma mua ia o na wahine a me na keiki. Ma platelet helu, i waena o nā mea a pau, ma nā keiki a me nā mākua loli ana ma ka makahiki. Ke'ī mai, ma ka keiki maʻamau huahelu o platelets ka loa ka laula, a me ka papa koa, mai 100 a hiki i 420 m 10 ⁹ / L (bn / L). Kēia oko a ua pili i ka mea i ka circulatory nenoaiu o nā pēpē i ka loa a me ka lolelua ka platelets, e like me nā keena koko, ka mea, 'Imi hoʻomōhala a me ka make. Kēia mau mai a hiki i ka makahiki.

I ka helu ana o platelets i loko o ke koko ke i naciiiuo nā poʻohiwi o, mahuahua ma hope, pili physical exertion, a i kela la i keia fluctuations.

platelet kūmau no na kanaka, na wahine, na keiki

Familiarize oe iho me na rula o ka mea o na kanaka, na wahine a me na keiki, ke kaumaha ma muli makahiki hiki ia i loko o ka papaʻaina ma lalo nei.

Kekahi kumu i hōʻike mai i ka uku o ka platelet i loko o na kanaka i ka 320 m 10 ⁹ / ho'āo ai. O ka iki OOAOAaXUEIEʻikepili.

Platelets: ka kōmi ma na kanaka

Kuu iho la ka waiwai i ia i loko o ka ikaika ke keka ma hope o 60 makahiki. Ke kaumaha ma muli o ka makahiki o kekahi o na mau Ikepili o ke koko kiko'î a ke hoʻololi. Ua pili no hoi ia ia i ke ana, e like me platelets. Ke kūmau i loko o nā kānaka ma luna o ka makahiki o keia aiao ua i hoakaka ia ma ka papaʻaina.

I adulthood, i ka helu ana o platelets i lilo iki emi. Kēia papaʻaina maopopo hōʻike pehea loli aʻe ke kaumaha ma muli o ka makahiki o ka uku anakahi like platelets. Ke kūmau i loko o nā kānaka 60 makahiki o ka makahiki ua iki hoemi like i na aiee o ui kanaka.

He aha e hana ana i ka loa kiʻekiʻe o platelets?

Ke mau Ikepili o ke koko , a me ka hemoglobin, leucocytes, erythrocyte sedimentation uku a me ka leukocyte helu mea nui he anakahi, a me platelets. Normal na kanaka i loko o ko lākou koko i ka 400, na wahine, - i ka 380 m 10 ⁹ / ho'āo ai. Inā keia aka mea nui kiekie ae, alaila, he ano kapa thrombocytosis. Kēia hiki i hoʻomāhuahua mau ana i ke koko clotting. Akā, ka mea, aole i symptomatically hoike. Pinepine hōʻike loa ma ka ulia - i ka manawa he mau koko hoao i loko o ka oaeouee? Nana. Thrombocytosis ke'ākoʻakoʻa ma lalo o ke ana ma lalo nei:

• Oncological keʻano o ka hanaʻana.
• Mielofiboz.
• Maʻi hoʻoʻino keʻano o ka hanaʻana.
• Infectious maʻi.
• Ke postoperative wā.
• Eritromiya (maʻi leukemia).
• Ma hope o ana o ka spleen (splenectomy).
• I ka hao deficiency anaemia.
• E like me ka hopena o ka hoʻolōʻihiʻia pono o kekahi mau lapaʻauʻia, e like me corticosteroids.

A pau o kēia kūlana hiki i ka mahuahua ana o keia anakahi, like platelets. Ke kūmau i loko o ke koko o na kanaka ka mea, e IeAUPIIe, IAa IO iki luna ma mua i loko o na wahine a me na kamalii. A hōʻemi iki mahuahua ma ka platelet hiki ma hope mālama nui hoounauna. Kēia mea,ʻaʻole he pathology. Ma hope o ke koena, keia huahelu ke hele mai hoʻi i ka maʻamau. Thrombocytosis mea iniiaiie a me nā haumāna.

Helu thrombocytosis hookomo ana i

Ke iniiaiie thrombocytosis hualoaʻa, mai kāna hana o ka hematopoiesis (ho okumu a me maturation o ke koko aeee), iwi lolo anei i keena. Nā kumu ke e:

• Kekahi ano o ka anemia.
• Eritromiya.
• Maʻi myeloid leukemia.
• Fibrotic degeneration o ka iwi ka lolo (myelofibrosis).
• Idiopathic thrombocythemia, hiki e mahuahua ai ka platelet helu i ka 4,000.

Secondary thrombocytosis hookomo ana i

Secondary thrombocytosis e hoʻomōhala ana i like me ka hopena o pathological kūlana (maʻi) e ma loko krovetvoritelnyh kino. Ka loa e like me ka kumu o ka haumāna thrombocytosis mea he maʻiʻaʻai.

Hiki kumu o ka haumāna thrombocytosis:

• Rheumatoid arthritis.
• Ka rumatika (ka pololei inoa no keia maʻi - huʻi rheumatic kuni).
• Osteomyelitis a necrotic kaʻina hana i loko o ka iwi lolo.
• Ulcerative colitis.
• Loa ake maʻi, e like me cirrhosis.
• Tuberculosis.
• Neoplastic keʻano o ka hanaʻana, e laʻa me, carcinoma, lymphoma a Hodgkin ka maʻi.
• Nui ke koko me keia poho.
• Huʻi hemolysis (loa ana i loko i ka hoʻopöʻino 'ia o erythrocytes ia lŘlŘ).

He aha ka mea haʻahaʻa platelet helu?

Thrombocytopenia - he ano i loko o ke koko a platelets i hoemiia. Ke kūmau i loko o nā kānaka i loko o kekahi mau kumu i loaʻa mai i 320 ieeeea? Aeee no hano, oiai ma kekahi - 400, a me ka mea ma lalo nakinakiia ma kekahi hihia HEN, mai 180 keena. Hoemi i kēia huahelu mea mau manawa e e noʻonoʻo thrombocytopenia.

Ke kumu paha e:

• Infectious keʻano o ka hanaʻana.
• Ooieoeiiaeuiuo abnormalities o ka iwi lolo.
• Hāpai keiki, a menstruation i loko o nā wāhine.
• Anemia o nāʻano likeʻole.
• Leukemias.
• Nā kūpuna mai.
• ʻO nā palapala 'ole o ka mea kaumaha ke hooheheeia.
• Alcohol i ka nui mea.
• Papakaukau kahe ana ke koko.
• E lawe i kekahi mau ai '(e like me antibiotics, analgesics, estrogens).

Deviations mai maʻamau platelet aiee ma kekahi ala e pono akahele hookolokolo a me ka hana o ka ai 'ole wale, akā, iʻai i kūpono.
