Plasma

Ropa mumwe zvinokosha munyama muviri, chine mvura mugove (plasma) kuti ichiputswa zvinhu uyewo sero (shape) zvinhu.

The mugove emura - the plasma inopfuura hafu bhuku kwayo (52-60%). Macroscopically - kwakanyatsojeka (dzimwe nguva zvishoma ramakore) homogeneous yellowish mvura kuunganidza chokumusoro chikamu nhumbi ropa mushure kunayisa yakaumbwa zvinhu. Histologically, chinhu intercellular fuma mvura mugove ropa.

Kutaura zvazviri, mvura iyi mapuroteni (8.7% zvakayerwa), ukaparadzawo mairi munyu uye mamwe makemikari yeimwe. fő yeplasma rine anenge 900g emvura, 60-80g mapuroteni (kuti 4% kwemapurotini zvose zviri mumuviri) uye 20g yakaderera samolecular uremu yeimwe. In zvachose, mapuroteni eplasma anenge 100: sealbumin, α1-, α2-, β-, γ-globulins.

Main mapuroteni eplasma - sealbumin iri (4-5%), fibrinogen (0.2-0.4%), globulins (3%), immunoglobulins (mapuroteni anokonzera kutapata pamwero) uye yakananga mapuroteni kuti vanobatanidzwa munyaya dzinotsanagura coagulation ropa. The sezvamunoita zvinosanganisira ayo zvinokurisa (shuga, lipids), mahormone, mafuta, shuga, mavhitaminzi uye zvicherwa, yokupedzisira uye zvenguva metabolites, electrolytes, inorganic ions.

Mune imwe nhengo utano, pachiyero mapuroteni mu yeplasma anodzokororwa nguva dzose. In zvirwere zvomukati munyaya catabolism uye kwetunhu, avo wevasungwa kuchinja.

Plasma ane nhamba mitambo. Chokutanga, rine chokufambisa masero eropa. uyewo chinomiririra inokosha kuchengeterwa mvura mumuviri. The mvura mugove midziyo ropa kunodzivisa akanamatira pamwe chete uye kuita clogging kubudikidza thrombi, zvinhu nhengo okisijeni uye zvinovaka muviri, inodzora BP.

A yoga boka mapuroteni eplasma - antibody. Inokuchengetedza muviri kubva nemavhairasi, notumwe, mabhakitiriya, masero kenza (zvose nevamiririri vatorwa). Coagulation mapuroteni, izvo naiyewo mvura mugove ropa, kudzivirira kubuda ropa uye kudzivirira kurasikirwa neropa. Mukuwedzera, plasma chidhiraivho uye transports mahormone zvinobatanidzwa pakuchengetedza tembiricha yakatsiga.

Plasma lipoproteins unotora - yakakwirira samolecular uremu mvura-soluble kunzwisisa remubatanidzwa kupa lipid chokufambisa mapuroteni uye lipids dzeropa kuti mapazi uye munyama. Vari dzinoratidzwa chinokosha marongerwo.

Sezvo plasma kunoramba rinopa masero ose zvinodiwa zvoupenyu uye kunobvisa tsvina kwavari, ipapo rinoungana pamusoro nguva yakawanda "marara". In pauduku hwake, plasma akajeka uye zvakachena, asi nezera haikwanise kurarama zvizere kubudiswa "tsvina" uye rinoungana kufanira muviri makemikari. It anorasikirwa pachena kwayo, kuwana madhaka kwerima guru. Naizvozvo, nzira ine plasmapheresis parinhasi kubatsira dzifambirane nemvura chikamu ropa.

Saizvozvowo kuenda anyatsoronga yeplasma - ne kupatsanura masero neropa centrifugation unokosha chikwata (plasmapheresis). Kuita plasma chinoguma Ndadzoka tsvuku masero eropa kuti anyatsoronga zvichiitwa. The mvura mugove ropa rurefu zviri maplatelet inoshandiswa somushonga stimulator kuporesa uye patsva zviri munyama siyana muviri.

Kwete kare, masayendisiti vakagumisa kuti plasma anochengeta zvakavanzika vechidiki. Nhasi kare kune nzira ropa mupiro nechinangwa kwohumwe Hardware layering. Mumwe wavo - plasma rukoko rurefu Kuwanda maplatelet raitongwa murwere pasi ganda uye anotanga vakiridza mukati. Izvi zvinotungamirira wrinkles vashoma uye yekudyidzana rejuvenates ganda. Munguva yemberi iri pedyo, mushonga achakwanisa kupora kwete chete ganda nenzira yakadaro, asiwo zvomukati.
