Isingeniso

Igazi, uketshezi olubalulekile olusekela impilo olugeleza emizimbeni yethu, luyingxube eyinkimbinkimbi yamaseli, amaprotheni, nezinye izingxenye ezahlukahlukene. Ngenqubo ye-centrifugation, ochwepheshe emalabhorethri ezokwelapha bangahlukanisa izingxenye ezahlukene zegazi, okubenza bakwazi ukuhlaziya nokuxilonga izifo ngokunembile. Lesi sihloko sihlola izizathu zokuthi kungani igazi lihlukaniswa ku-centrifuge kanye nezinzuzo eziningi ezihambisana nale nqubo. Ngaphezu kwalokho, sihlola amasu ahlukene asetshenziswa ekuhlukaniseni igazi, ukusetshenziswa kwalo mkhuba emkhakheni wezokwelapha, kanye nokusungula izinto ezintsha esikhathini esizayo kubuchwepheshe bokuhlukanisa igazi.

Isayensi Ebangela Ukuhlukaniswa Kwegazi

Igazi lakhiwe izingxenye ezintathu eziyinhloko: amangqamuzana abomvu egazi (ama-RBC), amangqamuzana amhlophe egazi (ama-WBC), kanye ne-plasma. Ngaphezu kwalokho, kunezinye izinto ezifana nama-platelet, ama-enzyme, ama-hormone, namaprotheni akhona egazini. I-Centrifugation inqubo esebenzisa izimiso zokubutha, ubuningi, kanye namandla e-centrifugal ukuhlukanisa lezi zingxenye ezahlukene. Isampula yegazi iqhutshwa ngesivinini esikhulu emshinini we-centrifuge, okuholela ekuhlukanisweni kwezingxenye ngokusekelwe ekubuneni kwazo.

Izinzuzo Zokusebenzisa Amasampula Egazi E-Centrifuging

1. Ukuthuthukisa Ukunemba Kokuxilongwa: Ukuhlukaniswa kwegazi kudlala indima ebalulekile ekuxilongweni kwelabhorethri. Ngokuhlukanisa izingxenye zegazi, odokotela bangahlaziya futhi balinganise izimpawu ezithile, njengamazinga e-cholesterol, amazinga kashukela, kanye nama-enzyme ahlukahlukene akhona ku-plasma. Lokhu kusiza ekuxilongweni kwezifo ngokunembile nasekunqumeni izinhlelo zokwelapha ezifanele.

2. Ucwaningo Nokuthuthukiswa: I-Centrifugation isibe ithuluzi elibalulekile ocwaningweni lwezokwelapha. Ososayensi bangahlukanisa izingxenye ezithile zamaseli egazi ukuze bafunde imisebenzi yazo, ukusebenzisana kwazo, kanye nezimpendulo zazo emithini noma ezimweni ezithile zezifo. Lokhu kusiza ekutholakaleni kwezindlela zokwelapha ezintsha, ukuthuthukiswa kwamathuluzi okuxilonga amasha, kanye nokuthuthukiswa kokuqonda kwethu izifo.

3. Ukuphepha Kokumpontshelwa Igazi: Ukuhlukaniswa kwegazi kuyisinyathelo esibalulekile ekuqinisekiseni ukuphepha nokuhambisana kokumpontshelwa igazi. Ukuhlukanisa igazi elinikelwe libe izingxenye kuvumela ochwepheshe bezokwelapha ukukhetha kuphela izingxenye ezidingekayo ezidingwa yilowo othola igazi, ukuvimbela ukusabela okubi kokumpontshelwa igazi futhi kukhulise ukusetshenziswa kwegazi elinikelwe.

Izindlela Ezihlukahlukene Zokuhlukanisa Igazi

1. I-Differential Centrifugation: Le ndlela isekelwe ekwehlukeni kosayizi kanye nobuningi bezingxenye zegazi. Ngokulungisa ijubane kanye nobude besikhathi se-centrifugation, amangqamuzana abomvu egazi, amangqamuzana amhlophe egazi, kanye ne-plasma kungahlukaniswa ngempumelelo kube yizingqimba noma izingxenyana ezihlukile.

2. I-Density Gradient Centrifugation: Kule ndlela, kusetshenziswa izinto zokulinganisa ubuningi, njengesixazululo se-sucrose noma i-iodixanol. Lapho isampula yegazi ifakwa ku-centrifuge, i-gradient yakha izendlalelo ezahlukene, futhi ingxenye ngayinye yegazi ihlala ngaphakathi kwe-gradient ngokuya ngobuningi bayo. Le ndlela ivumela ukuhlukaniswa okunembile kwezingxenye ezifunwayo.

3. I-Microfluidic Centrifugation: Amadivayisi e-miniaturized centrifugation athole ukuthandwa ngenxa yekhono lawo lokucubungula amasampula egazi amancane ngokushesha. Lawa madivayisi "elabhorethri-on-a-chip" asebenzisa iziteshi ze-microfluidic kanye namandla e-centrifugal ukuhlukanisa izingxenye zegazi ngempumelelo nangokulula.

Ukusetshenziswa Kokuhlukaniswa Kwegazi Emkhakheni Wezokwelapha

1. I-Hematology: Ukuhlukaniswa kwegazi kuvumela odokotela ukuba benze izibalo eziningiliziwe zamaseli egazi futhi bathole ukukhubazeka, njenge-anemia, i-leukocytosis, kanye nokutheleleka ngokusekelwe enanini kanye nohlobo lwamaseli amhlophe egazi akhona.

2. I-Clinical Chemistry: Ukuhlola amasampula egazi nge-centrifuging kwenza kube lula ukulinganisa kahle imingcele yamakhemikhali, okuhlanganisa ukuhlolwa kokusebenza kwesibindi, ukuhlolwa kokusebenza kwezinso, ukuhlolwa kwamahomoni, kanye namaphrofayili e-lipid. Lokhu kusiza ekuxilongeni nasekuqapheni izifo nezimo ezahlukahlukene.

3. Ukugcinwa Kwegazi: Ukuhlukanisa igazi libe izingxenye zalo ngazinye kuvumela ukugcinwa kwegazi okuphumelelayo nokusetshenziswa kwalo. Amaseli abomvu egazi, ama-platelet, kanye ne-plasma kungagcinwa ngokwehlukana, okuqinisekisa ukutholakala okuqhubekayo kwezidingo zokumpontshelwa igazi ngesikhathi sezimo eziphuthumayo noma ukuhlinzwa.

Izinto Ezintsha Zesikhathi Esizayo Ebuchwephesheni Bokuhlukanisa Igazi

Ososayensi nonjiniyela baqhubeka nokulwela ukuthuthukisa amasu okuhlukanisa igazi nokuthuthukisa ubuchwepheshe obusha. Ezinye zezindlela ezingaba khona zifaka:

1. Ubuchwepheshe be-Lab-on-a-chip: Ucwaningo oluqhubekayo luhlose ukunciphisa nokwenza izinqubo zokuhlukaniswa kwegazi zibe ngokuzenzakalela, okuvumela ukuhlaziywa okusheshayo nokuphathekayo endaweni yokunakekelwa, ngisho nasezindaweni ezilinganiselwe izinsiza.

2. Ukuhlukanisa Okukhethiwe: Imizamo iyaqhubeka yokuthuthukisa amasu okuhlukanisa akhethekile futhi angenziwa ngezifiso ukuze kuqondiswe izingxenye ezithile ngaphakathi kwamasampula egazi. Lokhu kungaholela ekuxilongweni okunembe kakhudlwana kanye nokwelashwa komuntu siqu.

3. Amapulatifomu Okuhlaziya Okuzenzakalelayo: Ukuhlanganiswa kokuhlukaniswa kwegazi namapulatifomu okuhlaziya okuzenzakalelayo kungenza kube lula izinqubo zelebhu, kunciphise amaphutha abantu, futhi kuthuthukise ukusebenza kahle ngaphakathi kwezindawo zomtholampilo.

Isiphetho

I-Centrifugation inikeza izinzuzo ezinkulu emkhakheni wokuhlaziywa kwegazi kanye nokuhlukaniswa kwezimpawu. Ngokuhlukanisa izingxenye zegazi ezahlukene, ochwepheshe bezokwelapha bangathola ukuqonda okubalulekile ngezifo ezahlukahlukene, bathuthukise ukunemba kokuxilonga, futhi bathuthukise ukunakekelwa kweziguli. Njengoba kuqhubeka kwenziwa intuthuko ebuchwephesheni bokuhlukanisa igazi kanye nobuchwepheshe, ikusasa lalo mkhakha linentuthuko ethembisayo ezoguqula ngokungangabazeki indlela amasampula egazi acutshungulwa futhi ahlaziywe ngayo.
