Madzi a m'magazi

Magazi ndi chimodzi mwa zimakhala zofunika kwambiri m'thupi, chomwe ndi gawo madzi (madzi a m'magazi) zinthu kusungunuka komanso maselo (zooneka) zinthu.

The madzi gawo - ndi madzi a m'magazi ndi oposa theka la buku lake (52-60%). Macroscopically - chimaonekera (nthawi zina pang'ono mitambo) homogeneous chikasu madzi wambirimbiri mu kumtunda ziwiya magazi pambuyo mpweya unakhazikitsidwa zinthu. Histologically, ndi intercellular mankhwala amadzimadzi gawo la magazi.

Ndipotu, madzi ndi mapuloteni (8.7% ndi kulemera), ndi kusungunuka mmenemo salt ndi mankhwala ena organic. lita plasma lili pafupifupi 900g madzi, 60-80g mapuloteni (kuti 4% mapulotini zonse zopezeka mu thupi) ndi 20g mankhwala otsika maselo kulemera. Okwana pafupifupi 100 plasma mapuloteni: albumin, α1-, α2-, β-, γ-globulins.

Main plasma mapuloteni - albumin ndi (4-5%), fibrinogen (0.2-0.4%), globulins (3%), immunoglobulins (mapuloteni udindo mlingo chitetezo chokwanira) ndi mapuloteni zimene zimapatsidwa nawo njira ya coagulation magazi. The zikuchokera mulinso ake zakudya (shuga, lipids), mahomoni, mafuta, shuga, mavitamini ndi mchere, chomaliza wapakatikati metabolites, electrolytes, ayoni zochita kupanga.

Mu wathanzi chamoyo, mlingo wa zimapanga plasma anakhalabe zonse. Mu matenda a ziwalo nawo catabolism ndi kaphatikizidwe, kusintha awo ndende.

madzi a m'magazi angapo ntchito. Choyamba, lili mayendedwe maselo magazi. komanso akuimira malo oonekera kwa madzi m'thupi. Mbali madzi Mitsempha chindiletsa kusagwirizana ndiponso kupewa clogging ndi thrombi, katundu ziwalo mpweya ndi chakudya, nthawi magazi.

A gulu osiyana mapulotini plasma - chitetezo. Iwo kuteteza thupi ku tizilombo, bowa, mabakiteriya, maselo a khansa (wothandizira onse achilendo). Coagulation mapulotini, zimene zili mu gawo madzi magazi, kupewa magazi ndi kuteteza motsutsana kutaika kwa magazi. Komanso, magazi amazilamulira plasma nawatengera mahomoni zimafunika kutentha khola.

madzi a m'magazi lipoproteins limapangidwa - mkulu maselo kulemera madzi sungunuka zovuta pawiri kupereka zamadzimadzi mapuloteni zoyendera ndi lipids m'magazi ziwalo ndipo zimakhala. Iwo yodziwika ndi dongosolo lapadera.

Popeza madzi nthawi zonse kumabweretsa kwa maselo zofunika onse a moyo ndipo amachotsa zinthu zotha kwa iwo, ndiye icho amasonkhana pa nthawi zambiri "zinyalala". Mu ubwana wake plasma momveka bwino ndi woyera, koma ndi m'badwo sangathe kulimbana mokwanira ndi processing wa "zinyalala" ndipo amasonkhana zosafunika m'thupi mankhwala. Amalakatika chilungamo chake, kupeza matope mithunzi. Choncho, ndondomeko ya plasmapheresis alipo lero thandizo pomwe madzi mbali ya magazi.

Mofananamo ati plasma mwiniwake - ndi kulekanitsa maselo a mwazi ndi centrifugation pa gulu lapadera (plasmapheresis). Kulola madzi a m'magazi itha atabwerera maselo ofiira ndi ndondomeko mwiniwake. Mbali madzi a magazi ndi okhutira mkulu wa othandiza magazi kuundana ntchito mankhwala monga stimulator machiritso ndi kusinthika kwa zimakhala zosiyanasiyana za thupi.

Si kale, asayansi anapeza kuti madzi a m'magazi amasunga chinsinsi cha achinyamata. Today kale pali ndondomeko ya ndalama magazi ndi cholinga zina hardware layering. Mmodzi wa iwo - madzi a m'magazi wosanjikiza ndi mkulu wa ndende othandiza magazi kuundana kutumikiridwa kwa wodwalayo pansi pa khungu ndipo akuyamba m'maulendo mkati. Zimenezi zimabweretsa makwinya ochepa ndipo kwambiri rejuvenates khungu. Posacedwapa, mankhwala adzatha achire osati khungu ngati njira, komanso ziwalo.
