Txheej txheem cej luam. Diffuse axonal raug mob (DAI) yog ib hom kev raug mob hauv lub hlwb. Nws tshwm sim thaum lub paj hlwb hloov mus rau hauv pob txha taub hau sai sai thaum muaj kev raug mob tshwm sim. Qhov ntev txuas fibers hauv lub hlwb hu ua axons yog txiav raws li lub hlwb nrawm nrawm thiab decelerates hauv cov pob txha tawv ntawm pob txha taub hau.
Hauv qhov no, dab tsi tshwm sim rau cov hlab ntsha thaum lub sijhawm txiav plaub hau?
Ntev, tawg taus ntawm cov neurons (ib leeg paj hlwb cov hlwb hauv lub hlwb thiab tus txha caj qaum) kuj tau nrawm thiab ncab. Yog tias qhov cuam tshuam muaj zog txaus, axons tuaj yeem ncav cuag kom txog thaum lawv tawg. Qhov no hu ua axonal txiav . Thaum qhov no tshwm sim, cov neuron tuag.
Ib tug neeg puas tuaj yeem rov zoo los ntawm kev raug mob axonal? Rau qee qhov, rov zoo los ntawm a diffuse axonal lub hlwb raug mob yog ua tau-tab sis tsis muaj kev lav paub nrog qhov ntawd raug mob . Qhov hnyav ntawm lub hlwb qhov txhab, qhov chaw ntawm lub hlwb lawv nyob, koj txoj kev kho mob, thiab ntau lwm yam. ua tau cuam tshuam seb koj puas ua tiav rov zoo.
Yog li ntawd, shearing ntawm lub hlwb yog dab tsi?
Txiav yog kev ncab thiab tsim kua muag ntawm cov hlab ntsha me me uas suav nrog lub hlwb . Kawm paub ntau ntxiv txog kev tshawb fawb thiab neuroimgaging uas txiav tuaj yeem ua rau thaum lub lub hlwb raug mob.
Dab tsi yog Dai qib 3 mob hlwb?
Qib 2: Ib nrab diffuse axonal raug mob nrog gross focal lesions nyob rau hauv lub corpus callosum. Qib 3 : Ib qho hnyav diffuse axonal raug mob nrog nrhiav raws li Qib 2 thiab ntxiv focal lesions hauv lub hlwb.

Glycoproteins yog cov protein uas muaj cov oligosaccharide saw (glycans) covalently txuas nrog cov amino acid sab-saw. Glycoproteins kuj tseem yog ib qho tseem ceeb ua ke ntawm cov protein, uas lawv ua lub luag haujlwm hauv kev sib cuam tshuam ntawm tes -cell
Puas yog shearing ua rau mob plab?
Qhov txhab xws li mob rwj, kuj tseem hu ua mob txhab, yog tshwm sim los ntawm kev sib txhuam thiab sib tsoo. Kev sib txhuam yuav ua rau cov ntaub so ntswg puas xws li tawv nqaij, thaum lub zog txiav yuav ua rau cov nqaij hauv qab xws li cov rog thiab cov leeg
Dab tsi tiv thaiv shearing thaum tso tus neeg mob?
Txhawm rau txo qhov kev pheej hmoo ntawm kev raug mob ntawm txoj hlua khi rau hauv ib qho semi-Fowler los yog txoj hauj lwm ncaj ncees, ua tib zoo ceev faj tiv thaiv koj tus hlub los ntawm zawv zawg hauv txaj. Koj tuaj yeem ua qhov no los ntawm kev tsa tus taw ntawm lub txaj thiab propping lub hauv caug nrog hauv ncoo
Dab tsi yog axonal sensorimotor polyneuropathy?
Sensorimotor polyneuropathy yog ib qho txheej txheem thoob plaws lub cev (systemic) uas ua rau cov paj hlwb puas, paj hlwb (axons), thiab paj hlwb (myelin sheath). Kev puas tsuaj rau lub npog ntawm cov paj hlwb ua rau cov paj hlwb qeeb lossis nres. Kev puas tsuaj rau cov paj hlwb lossis tag nrho cov hlab ntsha tuaj yeem ua rau cov hlab ntsha tsis ua haujlwm
Dab tsi ua rau axonal degeneration?
Axonal degeneration tuaj yeem tshwm sim los ntawm ntau yam kev thuam tsis sib xws (Coleman, 2005). Piv txwv li, nws tshwm sim nyob rau hauv tej kab mob xws li ntau yam sclerosis, HSP, motor neuron kab mob, thiab Alzheimer's kab mob
