Palo ea li-T

Palo ea T-cell e lekanya palo ea lisele tsa T maling. Ngaka ea hau e ka laela tlhahlobo ena haeba u na le matšoao a sesole sa 'mele se fokolang, joalo ka lebaka la ho ba le HIV / AIDS.

Ho hlokahala sampole ea mali.

Ha ho litokisetso tse khethehileng tse hlokahalang.

Ha nale e kentsoe ho hula mali, batho ba bang ba utloa bohloko bo itekanetseng. Ba bang ba ikutloa feela ho hlaba kapa ho hlaba. Kamora moo, ho ka ba le ho phatloha kapa ho longoa hanyane. Haufinyane sena sea fela.

Lisele tsa T ke mofuta oa lymphocyte. Li-lymphocyte ke mofuta oa sele e tšoeu ea mali. Ke karolo ea sesole sa 'mele. Lisele tsa T li thusa 'mele ho loantša mafu kapa lintho tse kotsi, joalo ka libaktheria kapa livaerase.

Mofani oa hao oa tlhokomelo ea bophelo a ka laela tlhahlobo ena haeba u na le matšoao a sesole sa 'mele se fokolang (immunodeficiency disorder). E kanna ea laeloa haeba u na le lefu la li-lymph node. Lymph nodes ke litšoelesa tse nyane tse etsang mefuta e meng ea lisele tse tšoeu tsa mali. Teko e boetse e sebelisetsoa ho lekola hore na kalafo ea mefuta ena ea mafu e sebetsa hantle hakae.

Mofuta o mong oa T cell ke sele ea CD4, kapa "cell helper." Batho ba nang le HIV / AIDS ba etsa liteko tsa T-cell khafetsa ho lekola palo ea lisele tsa bona tsa CD4. Liphetho li thusa mofani ho lekola lefu le kalafo ea lona.

Liphetho tse tloaelehileng li fapana ho latela mofuta oa T-cell e lekiloeng.

Ho batho ba baholo, palo e tloaelehileng ea lisele tsa CD4 e tloha ho 500 ho isa ho 1,200 lisele / mm³ (0.64 ho isa ho 1.18 × 10⁹/ L).

Mekhahlelo e tloaelehileng ea boleng e ka fapana hanyane hara lilaboratori tse fapaneng. Li-lab tse ling li sebelisa litekanyo tse fapaneng kapa li leka liteko tse fapaneng. Bua le mofani oa hau ka moelelo oa sephetho sa hau sa liteko.

Litekanyetso tse phahameng ho feta T-cell li ka bakoa ke:

• Kankere, joalo ka acute lymphocytic leukemia kapa multiple myeloma
• Ts'oaetso, joalo ka hepatitis kapa mononucleosis

Maemong a tlase a T-cell a ka ba teng ka lebaka la:

• Tšoaetso e matla ea vaerase
• Ho tsofala
• Kankere
• Maloetse a immune system, joalo ka HIV / AIDS
• Phekolo ea radiation
• Kalafo ea steroid

Ho na le kotsi e nyane haholo e amehang ha ho nkuoa mali a hau. Methapo le methapo li fapana ka boholo ho tloha ho motho e mong ho ea ho o mong le ho tloha lehlakoreng le leng la 'mele ho ea ho le leng. Ho nka mali ho batho ba bang ho ka ba thata ho feta ho ba bang.

Likotsi tse ling tse amanang le ho huloa mali li nyane empa li ka kenyelletsa:

• Ho tsoa mali a mangata
• Ho akheha kapa ho ikutloa o le hlooho e boima
• Hematoma (mali a bokellanang ka tlasa letlalo)
• Tšoaetso (kotsi e nyane neng kapa neng ha letlalo le robehile)
• Li-punctures tse ngata ho fumana methapo

Hangata tlhahlobo ena e etsoa ho batho ba nang le boits'ireletso ba mmele bo fokolang. Ka hona, kotsi ea tšoaetso e ka ba kholo ho feta ha mali a tsoa ho motho ea nang le boits'ireletso ba mmele bo phetseng hantle.
