Momwe Centrifuge Imalekanitsira Magazi: Kupita Patsogolo ndi Njira

Chiyambi

Kulekanitsa magazi ndi njira yofunika kwambiri pa ntchito zosiyanasiyana zachipatala, zomwe zimathandiza asayansi, madokotala, ndi ofufuza kuphunzira zigawo zosiyanasiyana za magazi padera. Kuyezera magazi, njira yomwe imagwiritsa ntchito kuzungulira kwachangu, imagwira ntchito yofunika kwambiri pakulekanitsa magazi m'zigawo zake zosiyanasiyana. Nkhaniyi ikufotokoza mfundo zomwe zimapangitsa kuti kulekanitsa magazi kukhale koyezera magazi ndikuwonetsa kupita patsogolo ndi njira zomwe zimagwiritsidwa ntchito pankhaniyi.

1. Mfundo ya Centrifugation

Kutsegula magetsi kumagwira ntchito motsatira mfundo ya sedimentation, yomwe imagwiritsa ntchito kuchulukana kosiyanasiyana kwa zigawo zosiyanasiyana za magazi. Magazi akayikidwa mu centrifuge ndikuzungulira mofulumira, tinthu tating'onoting'ono timapita pansi pomwe zigawo zopepuka zimakhala pafupi ndi pamwamba. Kulekanitsidwa kumeneku kumachitika chifukwa cha mphamvu ya centrifugal yomwe imapangidwa ndi kuyenda kozungulira, komwe kuli kofanana ndi mtunda wochokera ku mzere wozungulira.

2. Mitundu ya Ma Centrifuge

Ma centrifuge amatha kugawidwa m'magulu awiri: ma centrifuge osiyana ndi ma density gradient centrifuge.

2.1 Ma Centrifuge Osiyanasiyana

Ma centrifuge osiyana amalekanitsa magawo a magazi kutengera kusiyana kwa kukula ndi mawonekedwe. Pogwiritsa ntchito liwiro lozungulira ndi nthawi zosiyanasiyana, centrifuge imatha kulekanitsa maselo ofiira a magazi, buffy coat (maselo oyera a magazi ndi ma platelet), ndi plasma. Njira imeneyi imagwiritsidwa ntchito kwambiri poyesa magazi nthawi zonse, monga kuwerengera magazi onse ndi kulemba magazi.

2.2 Ma Centrifuge a Gradient Ochuluka

Ma centrifuge a density gradient amagwiritsa ntchito kuchuluka kosiyanasiyana kwa zigawo za magazi. Njira yochepetsera kuchuluka kwa magazi, monga yankho la sucrose kapena iodixanol, imayikidwa mu chubu, ndipo magazi amawonjezedwa mosamala pamwamba pake. Panthawi yochepetsera kuchuluka kwa magazi, zigawo za magazi zimasuntha kudzera mu density gradient, ndikugawikana m'magulu osiyanasiyana. Njira imeneyi imalola kuti pakhale kulekanitsidwa ndi kutsukidwa kwa zigawo zinazake za magazi, monga mavairasi, mapuloteni, ndi organelles.

3. Kupita Patsogolo kwa Njira Zopatulira Magazi

3.1 Kuchepetsa mphamvu ya ultracentrifugation

Kuyeza magazi m'njira ya ultracentrifugation, komwe kumaphatikizapo kuzungulira magazi mwachangu kwambiri, kwasintha njira zolekanitsira magazi. Mothandizidwa ndi kuyesa magazi m'njira ya ultracentrifugation, asayansi amatha kupeza magawo ochepa a magazi, monga lipoproteins ndi exosomes. Njirayi imagwiritsidwanso ntchito pofufuza matenda opatsirana, kusanthula majini, ndi njira zoperekera mankhwala.

3.2 Kuchepetsa Ma Gradient pa Maphunziro a Ma Cellular

Mwa kuphatikiza density gradient centrifugation ndi flow cytometry, asayansi amatha kuphunzira kuchuluka kwa maselo enaake. Njira imeneyi imawalola kusiyanitsa mitundu yosiyanasiyana ya maselo ndi magazi athunthu kutengera zizindikiro zawo zapadera kapena makhalidwe ena. Kuphatikiza apo, density gradient centrifugation imalola kulekanitsa maselo ndi odwala khansa kuti apitirize kusanthula majini, zomwe zimathandiza pakupanga mankhwala apadera.

4. Ntchito Zachipatala

4.1 Kuika Magazi

Kupereka magazi m'thupi ndi gawo lofunika kwambiri pa njira zoperekera magazi. Pambuyo popereka magazi, magazi onse osonkhanitsidwa amazunguliridwa mu centrifuge kuti awalekanitse m'zigawo zake: maselo ofiira a magazi, ma platelet, ndi plasma. Kutengera ndi zofunikira zachipatala za wodwalayo, zigawozi zolekanitsidwazi zitha kuikidwa moyenerera. Mwachitsanzo, maselo ofiira a magazi amaikidwa ngati magazi akutuluka kwambiri kapena kuchepa kwa magazi m'thupi, pomwe plasma imagwiritsidwa ntchito pochiza matenda a magazi kuundana.

4.2 Mayeso Ozindikira Matenda

Kuyeza magazi m'magazi ndikofunikira kwambiri pa mayeso osiyanasiyana ozindikira matenda. Mwachitsanzo, panthawi yoyezetsa magazi m'magazi, plasma imalekanitsidwa ndi maselo a m'magazi kuti iwone momwe magazi amathira magazi. Imagwiritsidwanso ntchito kupatula zigawo zinazake za mayeso monga mayeso a chiwindi, mayeso a impso, ndi kusanthula kuchuluka kwa mahomoni. Mwa kulekanitsa ndi kusanthula zigawozi za m'magazi, madokotala amatha kuzindikira matenda osiyanasiyana ndikuyang'anira thanzi la odwala moyenera.

Mapeto

Kugawa magazi m'magazi m'zigawo zosiyanasiyana, zomwe zimathandiza kumvetsetsa bwino momwe thupi la munthu limagwirira ntchito. Chifukwa cha kupita patsogolo kwa njira zogawa magazi m'magazi, ofufuza ndi madokotala amatha kupeza zigawo zinazake zamagazi molondola komanso moyenera. Mwa kugwiritsa ntchito mphamvu ya kugawa magazi m'magazi, asayansi akukulitsa chidziwitso chawo cha matenda okhudzana ndi magazi, kupanga njira zatsopano zochiritsira, komanso kukonza chisamaliro cha odwala.
