Kwevanhu platelet basa. Iro basa rinoitwa maplatelet

Maplatelet tiri mumwe zvikuru zvinoriumba ropa revanhu. Nyanzvi vanokurudzira kuti varambe nhanho vari vakakwana, kana mikana yakawanda zvinouraya. Ndokusaka zvichikosha chaizvo kuziva chii chinosara chiri kuteererwa maplatelet.

zvinhu pfungwa

Maplatelet vari woita zvinoumba ropa iro kubatanidzwa normalizing hemostasis. By nemaziso maumbirwo sero, vasina cores. dhayamita wavo anenge 3 microns. Ivo akaumba pamusoro megakaryocytes mu mumwongo. In muropa, zvinhu izvi achagara kubva 5 kusvika 11 mazuva. Zvadaro rakaparadzwa chirwatata uye chiropa.

In patambo maplatelet vane woita ichiratidzika disk. Panguva activation, ivo kuzvimba uye kuva akafanana bhora. Sezvo chikuru kushanda maplatelet mumidziyo ropa kuderedza kudzivirira maronda, vanoumba outgrowths chaiwo anonzi pseudopodia. With miganhu izvi mhuru dzakabatanidzwa mumwe, i.e. kufamba aggregation danho. Ipapo masero vanoomerera mugove dzaparadzwa ari mudziyo. Mano aya anonzi adhesion. Zvinokosha kucherechedza kuti maplatelet vanokwanisa kukanda ropa kakawanda anobatsira Micro-zvinoriumba, akadai makemikari, kweserotonin, ADP, fibrinogen uye nevamwe. Izvi chinosiyanisa nevamwe masero matsvuku eropa.

Home platelet basa

Sezvo chikazozikamwa, masero aya ropa zviri kuitika munyika pakugwamba kwacho, kureva muna hemostasis. Ndiro huru mashandiro maplatelet. Nokuti womunhu, iyi ndiyo imwe inokosha. Kunoitawo kuti kudzivisa dzinokosha kurasikirwa ropa panguva yakanyanya kukuvara.

With basa iri maplatelet dzevanhu, vascular masvingo kuva vakasimba. Vangararai pfupi nguva kuzadza zvinokuvadza. Kutaura zvazviri, masero aya ropa nezvaanoita chinonyanya vascular chivhariso. Collapsing kwaitika maererano nesungano pakati makemikari, mapuroteni uye vanenge 40-zvinoriumba. Uyu chaizvo kunzwisisa utachiona mashandiro umo huru basa reDare maplatelet, prothrombin uye fibrinogen. The kudyidzana kwezvinhu zvine maatomu akafanana izvi kumbowanikwa muropa plasma.

Auxiliary platelet basa

Kuwedzera unodzivirira ehupfumi, Mavara ndiro Data ane chimwe chinobatsira kugona. It kunoratidzwa nesimba endothelium kwevanhu kweropa hurongwa. Izvi basa platelet nemidziyo inokosha zvisaririra zvinhu kuti pave normalization pakati aibuda tsvuku corpuscles mukuru kushanda zvomukati. Kubva pfuma iyi, ukuru kudzivirirwa muviri zvinoenderana (kutapata).

Uyewo, zvinhu ropa zviri kuitika mu patsva, ndiko kuti nokuporesa nyama pashure kukuvara. Izvi zvinoitwa kugovera wakakurumidza muitiro uye kusunungurwa kubva nemidziyo. Nemamwe mashoko, mashandiro maplatelet clogging mugove kunge kukuvara. Uyezve, vanenge kuti wakakurumidza ikure kwakakanganisa masero. Under kwacho kwaireva weboka polypeptide mamorekuru. Panguva platelet activation kunoitika uye kukura fibroblasts. Uyewo panguva iyi yakabereka microcomponents anokonzera muchitokisi kuchinja uye jekiseni pamwero kupora.

wokuyera

Muvanhu, maplatelet vanofanira nguva dzose kuva yaigamuchirwa nemiganhu. Kazhinji, asi ongororo wakapiwa zvinokosheswa por 1 fő ropa. Specificity kuti kutsikisa riri sezvinotevera: x10 ⁹ / l. Norm nokuti mukuru inhamba maplatelet vari kuwanda vezvikwata kubva 200 kusvika 400. Kuyaruka 15 kusvika 18 makore, nhamba idzi - 180-420. Vana kusvika makore 15 pachiyero masero zvichisiyana 150 kusvika 450 dzakabatana. Vachangoberekwa, shoma chikumbaridzozve iri 100, uye kufadza - 400.

Zvinokosha kucherechedza kuti nehadzi kunze maplatelet kungava zvishoma pazasi apa mitemo. It kunobva vasiri zvatariswa uye mwero mahormone. Mukuwedzera, panguva kumwedzi zvishoma pachikumbaridzo platelet count anodonhedza zvikuru nokuda kurasikirwa ropa. Mamiriro ezvinhu ari kuchengetwa vakadzi vane pamuviri, kana pachiyero masero rokuzvivandudza rakaita kuti irambe anogona kuderedzwa yekudyidzana. Izvi imhaka kuwedzera Vhoriyamu mvura muropa. Naizvozvo, kana ongorora akaona kuderera kwenhamba Micro-zvinoriumba. Zvakakosha kunzwisisa kuti nhamba zviratidzi pamusoro maplatelet - haasi pfungwa. Migumisiro kuongorora chero zvazvingava zvakafanira kuti chiremba kuita mamwe zvidzidzo kuona kubudirira yezviito zvavo. nzira iyi inonzi coagulation.

Zvarakasiya vavo zvikonzero

Kana bvunzo ropa yakaratidza kuti muviri kushaya kana overabundance kuti maplatelet chinhu zvaikosha kupfuura kuongorora mamwe zvokurapa. Ichi ndicho chokutanga yambiro chiratidzo chokuti kunoratidza kukura ane chirwere chakakomba.

Sezvo maplatelet zvinokosha ropa uye zvinokosha, chero yakatsauka kubva ndozvakajairwa kunokanganisa zvinonyatsorehwa mamiriro muviri. Kuderedza uwandu masero kunowedzera mikana anoporesa refu kunyange shoma kukuvara. Nemamwe mashoko, ropa pakugwamba kushoma. By kuwedzera huwandu maplatelet kusashanda unodzivirira ushande. Panyaya iyi, pangagara chichagadzirirwa remubatanidzwa huru kutyora dzeropa. Somugumisiro, pane pangozi yokuita ropa. Sudden zvarakasiya kubva zvokurapa zvinodiwa angava anoratidza mangwanani kenza pechikuva.

Nokuti kudzivirirwa uye dzigadziridzwe platelet kuverenga, vanachiremba vanokurudzira kudya zvinovaka muviri. Zvokudya anogara zvakawanda zvinofanira kuva vhitamini B12 uye folic acid.

Neb platelet functionality

Izvi ezvinhu kunoitika apo chinokosha zvinoderedza uwandu regenerating masero muropa. Somugumisiro kwokuderera zvomukati vari kubatira zvirwere. Izvi tigume zvikurukuru pamusoro chiropa uye thyroid. Zvikonzero kuderedza maplatelet vavo functionality kungava zvirwere zvakadai gwirikwiti, neleukemia, gwirikwiti. The inotyisa izvi ndizvo kenza. Mukuwedzera, kuderera vakachengeta Varwere pashure mishonga, uyewo mune chiitiko ane ovhadhozi kuti asipurini uye kupera mvura mumuviri. Vamwe mishonga simba kunogona kukanganisa kukura masero eropa.

Kwakaderedza kwevari maplatelet kunoda fanira kurapwa. Zvikurukuru chiremba anofanira mishonga pharmacological nevamiririri. Uye panzvimbo yechipiri ndiwo kudya nemiriwo ekudzivirira. Traditional dzinoshandiswa simba, uye kunonoka kurapwa kunogona kutungamirira zvisingadzivisiki nemigumisiro. Zvakakosha panguva prophylaxis kutora thinners ropa, zvakadai analgesics, "asipurini," boka sulfa.

chinhu overabundance kuti maplatelet

Kuwedzera pamwero masero rokuzvivandudza rakaita kuti irambe unotaura nezvekenza. Uyezve, zvinokanganisawo ebetsero mashandiro anoita maplatelet. Oversupply masero zvakare zvinogoneka sepsis kana kuvhiyiwa zvinotevera kubvisa chirwatata. mhosva nomumwe kungava zvakakomba zvemukati kubuda ropa.
Kukurumidza Zvakawanikwa maplatelet mumidziyo ropa akaumba emboloobrazovaniya. dambudziko iri zvinoda pakarepo mhinduro. Zvinofanira kucherechedzwa kuti vaizviita havapi mhinduro. Pane kuchangoita pharmacological kurapa. Zvikuru nevakawanda zvinodhaka vangazivikanwa "pirabutol" uye "asipurini". Zvinokoshawo kudzivisa chero zadzisa muviri.

fungidziro zvirwere

By achideredza huwandu maplatelet yakakwirira mukana aplastic kupererwa, chirwere Verlgofa uye Gaucher tsitopenichesky purpura.

With nokuwedzera kwenhamba matsvuku ndiro pane mukana kuti nedengue fever uye hemolytic syndrome. Asi chokutanga zvose zvinofanira kuongororwa kuti kenza.

Kutyora platelet aggregation uye adhesion kunoguma Bernard-Soulier urwere, of Willebrand Pudlaka, Scott.

Pamusoro kukundikana muviri masero matsvuku akacherechedza atherosclerosis, ischemic mwoyo chirwere, cerebrovascular chirwere uye arterial, marariya, asima, uye kenza.
