Ke, i-ultraviolet phototherapy iyiphatha njani i-psoriasis?
1.Tyena unyango oluqhelekileyo psoriasis
Amachiza avela kwimixholo yonyango oluphambili lwe-psoriasis ephakathi ukuya kwephakathi.Ukunyangwa kwamachiza okunyanga kuxhomekeke kwiminyaka yesigulane, imbali, uhlobo lwe-psoriasis, ikhosi yesifo kunye nezilonda.

2.Tiimpawu ze-ultraviolet phototherapy
I-Ultraviolet phototherapy yonyango olucetyiswayo ngakumbi kwi-psoriasis ngaphezu kweziyobisi.I-Phototherapy ikakhulu ibangela i-apoptosis yeeseli ze-T kwizilonda ze-psoriatic, ngaloo ndlela inqanda amajoni omzimba asebenze ngokugqithisileyo kunye nokukhuthaza ukubuyiswa kwezilonda.
Ibandakanya ikakhulu i-BB-UVB(>280~320nm), i-NB-UVB(311±2nm), i-PUVA(ibhafu yomlomo, yonyango kunye neyendawo) kunye nolunye unyango.Isiphumo sonyango se-NB-UVB yayingcono kune-BB-UVB kwaye ibuthathaka. kune-PUVA kunyango lwe-UV lwe-psoriasis.Nangona kunjalo, i-NB-UVB lolona nyango luxhaphakileyo lusetyenziswa kwi-ultraviolet ngokhuseleko oluphezulu kunye nokusetyenziswa kakuhle.Unyango lwe-UV oluphezulu luyacetyiswa xa indawo yolusu ingaphantsi kwe-5% yendawo yonke yomzimba.
3.NB-UVB unyango lwe psoriasis
Kunyango lwe-psoriasis, ibhendi ephambili esebenzayo ye-UVB ikuluhlu lwe-308 ~ 312nm.Ibhendi esebenzayo ye-NB-UVB (311 ± 2nm) kunyango lwe-psoriasis icocekile ngakumbi kune-BB-UVB (280 ~ 320nm), kwaye umphumo ungcono, kufuphi nomphumo we-PUVA, kwaye unciphisa ukusabela kwe-erythematous. okubangelwa yibhendi engasebenziyo.Ukhuseleko olulungileyo, akukho nxulumano nomhlaza wolusu lufunyenwe.Okwangoku, i-NB-UVB sesona sicelo sekliniki sithandwa kakhulu kunyango lwe-psoriasis.
