Kugawanika kwa mapaleletiti - ndi chiyani?

Mipata yaing'ono ndiyo maselo ang'onoang'ono a magazi omwe amayenera kutsekemera madzi. Amatenga mbali:

• poletsa magazi (hemostasis);
• pakudyetsa makoma a mitsempha.

Kodi ndondomeko ya agglate ikuchitika bwanji?

Tikadula pang'ono, thupi limasonyeza vuto. Thrombocyte imathamangira ku zombo zowonongeka, zomwe zimayamba kumangiriza pamodzi. Izi zimatchedwa aggregation. Zimachitika mu magawo awiri:

1. Choyamba, mapepalawa amatchulidwira palimodzi - iyi ndi gawo loyambako la mapangidwe a thrombus.
2. Kenaka amamangidwa pamakoma a zombozo.

Pambuyo pake pamapeto a mapulogalamu ena, timagulu timeneti timagwiritsabe ntchito, ndipo chifukwa chake thrombus imakula mpaka imatseka makoma a mitsempha yotayika kuti magazi asatulukire. Komabe, pali ngozi yomwe ingawonongeke pakuwonjezereka kwa magazi - izi zimayambitsa mtima, zikwapu.

Kwa zosachitika zilizonse, chonde tumizirani katswiri.

Mayeso a magazi kuti atseke

Phunziro la magulu a platelet ndikofunika kuyesa magazi:

1. Ngati pali zilonda zazing'ono, zilonda sizichiritsa, nthawi zambiri pamakhala magazi m'mphuno - ichi ndi chizindikiro chakuti magazi coagulability amatsitsa.
2. Ngati pali kutupa - m'malo mwake, coagulability ikuwonjezeka.

Kufufuza kumaphatikizapo poyambitsa ndondomeko yowonongeka. Monga zinthu zopangira mankhwala, zomwe zimagwiritsidwa ntchito kwambiri, zimagwiritsidwa ntchito.

Kugawanika kwa mapaleletti kumafufuzidwa mothandizidwa ndi anthu oterewa:

• adrenaline;
• zigawo zikuluzikulu za khoma: adenosine diphosphate (ADP);
• ristocetin (ristomycin);
• collagen;
• serotonin.

Kuphatikizidwa kwapadera kwa mapaleletti kumatsimikiziridwa popanda operekera.

Musanayambe kuyesa, muyenera kukonzekera bwino kuti magazi ayambe kulondola. Kuti muchite izi, muyenera kutsatira malamulo awa:

1. Musanayese mayeso, musamamwe mankhwala onse a aspirin (dipyridamole, indomethacin ndi ena) ndi mankhwala olerera.
2. Kusanthula kumatengedwa m'mimba yopanda kanthu, patatha maola 12 mutha kudya, makamaka sikoyenera kudya zakudya zamtundu.
3. Musadzisokoneze thupi lanu, khalani chete.
4. Kwa tsiku kuti musamamwe khofi, zakumwa zoledzeretsa, osati kudya adyo komanso kusuta.
5. Ngati thupi liri ndi kutupa, kusanthula kuyenera kusinthidwa.
6. Ndikofunika kudziwa kuti nthawi ya kusamba, kuchepa kwa magazi kumaphatikizapo akazi, ndipo izi zingakhudze zotsatira za kusanthula.

Chizoloŵezi cha platelet aggregation

Mitengo yambiri yamagazi m'magazi imatanthauza kuti munthu ali ndi thupi labwino, mapangidwe ndi ziwalo zimaperekedwa ndi mpweya ndi chitsulo chokwanira.

Chizolowezi cha zomwe zili m'mapuloletiti amakhala 200 mpaka 400 x 109 / l. Komanso, mu phunziro la ma laboratory la stopwatch muyeso nthawi yomwe magulu akuluakulu a mapulateleti amapangidwa. Nthawi yachidziwitso nthawi ndi masekondi 10 mpaka 60.

Kuwonjezeka kwa platelet aggregation

Kuti mumvetsetse mtundu wa chikhalidwe, pamene pulogalamu ya platelet yowonjezera, muyenera kumvetsera izi: magazi ndi owopsa, amayenda pang'onopang'ono kupyola mitsempha ya mitsempha. Izi zimawonekera ngati kumverera kwa kufooka, kutupa. Thrombocytosis yoteroyo imachitika pamene:

• kufalikira kwa matenda a atherosclerosis a mitsempha ya magazi;
• matenda;
• shuga;
• liwu;
• khansara ya m'mimba kapena impso;
• malingaliro ;
• mutatha kuchotsedwa kwa nthata;
• sepsis.

Mwazi wandiweyani umayambitsa mavuto ngati awa:

• myocardial infarction;
• kupweteka kwa mitsempha ya miyendo;
• kupweteka ;
• imfa yodzidzimutsa kuchoka pamtunda wa aorta ndi thrombus yotsalira, ndi zina zotero.

Kuchepetsa gulu la mapaleletti

Ndi nambala yaing'ono yamapiritsi m'mitsempha ya mitsempha imakhala yowopsya, magazi amasiya movutikira.

Ngati pulogalamu yaplatele yafupika, muyenera:

1. Pewani kuvulala.
2. Samalani ndi mankhwala ndi mowa.
3. Idyani bwino, chotsani zokometsera ndi zakumwa zamchere.
4. Pali zakudya zambiri zitsulo (beets, maapulo, buckwheat, nyama, nsomba, parsley, tsabola, mtedza, sipinachi).
