Ukusetyenziswa kwe-UV phototherapy kunyango lwe-psoriasis

I-Psoriasis, isifo sesikhumba esingapheliyo, esiphindaphindiweyo, esivuthayo kunye nesistim esibangelwa ziziphumo zofuzo kunye nokusingqongileyo.I-Psoriasis ngaphezu kweempawu zesikhumba, kuya kubakho i-cardiovascular, metabolic, digestive and malignant tumors kunye nezinye izifo ezininzi. Nangona ingosuleli, ibuhlungu kakhulu eluswini kwaye inempembelelo enkulu kwimbonakalo, ezisa umthwalo omkhulu ngokwasemzimbeni nangokwengqondo kwizigulane kwaye ichaphazela kakhulu umgangatho wobomi.

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.

Iziyobisi ezisetyenziswa ngokuqhelekileyo ziyi-glucocorticoids, i-vitamin D3 derivatives, i-retinoic acid kunye nokunye. Ukusetyenziswa okucwangcisiweyo kweziyobisi zomlomo okanye i-biologics ezifana ne-methotrexate, i-cyclosporine kunye ne-retinoic acid inconywa kwizigulane ezine-scalp psoriasis ezihamba kunye nezilonda ezilinganiselweyo.

 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 sokunyanga se-NB-UVB sasingcono kune-BB-UVB kwaye sibuthathaka. kune-PUVA kunyango lwe-UV lwe-psoriasis. Nangona kunjalo, i-NB-UVB lolona nyango luqhelekileyo lusetyenziswa kwi-ultraviolet ngokhuseleko oluphezulu kunye nokusetyenziswa okufanelekileyo. 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.
