I-Psoriasis, sisifo solusu esingapheliyo, esiphindaphindayo, esidumbayo nesihamba emzimbeni esibangelwa ziziphumo zemfuza kunye nokusingqongileyo.I-Psoriasis ukongeza kwiimpawu zesikhumba, kuya kubakho neethumba zentliziyo, i-metabolic, i-digestive kunye ne-malignant kunye nezinye izifo ze-multi-system. Nangona ingenasifo, iyenzakalisa kakhulu ulusu kwaye inefuthe elikhulu kwinkangeleko, nto leyo ezisa umthwalo omkhulu emzimbeni nasengqondweni kwizigulana kwaye ichaphazela kakhulu umgangatho wobomi.
Ngoko ke, i-ultraviolet phototherapy iphatha njani i-psoriasis?
1.Tunyango oluqhelekileyo lwe-psoriasis
Amayeza asetyenziswa kwiindawo zokuthambisa zezona ndlela ziphambili zonyango lwe-psoriasis ethambileyo ukuya kwephakathi. Unyango lwamayeza asetyenziswa kwiindawo zokuthambisa zesikhumba luxhomekeke kubudala bomguli, imbali yakhe, uhlobo lwe-psoriasis, indlela agula ngayo kunye nezilonda.
Amayeza asetyenziswa rhoqo yi-glucocorticoids, i-vitamin D3 derivatives, i-retinoic acid njalo njalo. Ukusetyenziswa rhoqo kwamayeza omlomo okanye izinto eziphilayo ezifana ne-methotrexate, i-cyclosporine kunye ne-retinoic acid kuyacetyiswa kwizigulana ezine-scalp psoriasis ehamba nezilonda eziphakathi ukuya kwezinzima.
2.Tiimpawu ze-ultraviolet phototherapy
I-Ultraviolet phototherapy lolona nyango lucetyiswayo lwe-psoriasis ukongeza kumayeza. I-Phototherapy ikakhulu ibangela i-apoptosis yeeseli ze-T kwizilonda ze-psoriatic, ngaloo ndlela ithintela inkqubo yomzimba yokuzikhusela esebenza kakhulu kwaye ikhuthaza ukubuyela umva kwezilonda.
Iquka ikakhulu i-BB-UVB(>280~320nm), i-NB-UVB(311±2nm), i-PUVA(yomlomo, yokuhlamba ngeyeza kunye neyendawo) kunye nezinye iindlela zonyango. Isiphumo sokunyanga se-NB-UVB besingcono kune-BB-UVB kwaye sibuthathaka kune-PUVA kunyango lwe-psoriasis nge-UV. Nangona kunjalo, i-NB-UVB lolona nyango lwe-ultraviolet olusetyenziswa kakhulu olukhuselekileyo kwaye lusebenziseka lula. Unyango lwe-UV olusecaleni luyacetyiswa xa indawo yesikhumba ingaphantsi kwe-5% yendawo yonke yomzimba. Xa indawo yesikhumba ingaphezulu kwe-5% yendawo yomzimba, unyango lwe-UV olucwangcisiweyo luyacetyiswa.
3.Unyango lwe-NB-UVB lwe-psoriasis
Kunyango lwe-psoriasis, ibhendi esebenzayo ye-UVB ikwi-308 ~ 312nm. Ibhendi esebenzayo ye-NB-UVB (311±2nm) kunyango lwe-psoriasis icocekile ngakumbi kuneye-BB-UVB (280~ 320nm), kwaye isiphumo singcono, sisondele kwisiphumo se-PUVA, kwaye sinciphisa impendulo ye-erythematous ebangelwa yibhendi engasebenziyo. Ukhuseleko oluhle, akukho nxu lumano nomhlaza wolusu olufunyenweyo. Okwangoku, i-NB-UVB yeyona ndlela idumileyo yonyango lwe-psoriasis.
