Mankhwala amakono amayamba kusintha. Chitsanzo chowonekera cha izi ndi chithandizo cha photodynamic. Njira yothandizira imeneyi yakhazikitsidwa kwa nthawi yayitali, koma yakhala ikugwiritsidwa ntchito mwazaka zingapo zapitazo. Chifukwa cha mphamvu yake, chithandizo cha photodynamic chapeza ntchito m'magulu ambiri a mankhwala.
Kodi kusiyana kwakukulu ndi ubwino wa chithandizo cha laser photodynamic ndi chiyani?
Maziko a chithandizo cha photodynamic ndi photosensitizers. Awa ndiwo mankhwala apadera omwe amamvetsetsa kwambiri kuwala. Chifukwa cha kukhudzidwa kwa iwo mothandizidwa ndi mafunde a laser kutalika kwake, zotsatira zoyenera zimakwaniritsidwa.
Mwachidule, mankhwalawa-photosensitizer amalowetsedwa m'thupi. Njira zamakono zonse sizili zowononga ndipo zimatha kuwonjezereka mwamsanga m'matenda. Pambuyo pake, zipangizo zamagetsi zimagwiritsidwa ntchito. Ndicho chitsimikizo cha ma radiation, omwe amalola kulamulira kutalika kwa mphamvu ndi mafunde. Panthawi yolumikizana ndi laser, photosensitizer amasangalala, chithunzi cha photochemical chimayambira, chifukwa cha zomwe zimawomboledwa. Zomalizazi zimakhudza kwambiri maselo a m'mitsempha, ndipo pang'onopang'ono amasankha. Pambuyo pa chotupacho mutatha njirayi, minofu yathanzi imapangidwa.
Thandizo la photodynamic likuwonetsedwa pa mavuto awa:
- melanoma ;
- khansa ya khungu (squamous, basal cell, metatypic);
- ziphuphu zosagwiritsidwa ntchito ndi njira zina zothandizira;
- Mapuloteni osagwiritsidwa ntchito (nthawi zambiri amakhala m'malo ovuta kufika).
Nthawi zina chithandizo cha photodynamic ndicho njira yokhayo yothandizira wodwala. Inde, njira iyi si yotsika mtengo, koma zotsatira zomwe zikuwonetsa ziri zoyenera ulemu.
Thandizo la photodynamic mu incology
Poyamba, njirayi inakhazikitsidwa mwachindunji kuchiza khansa. Mukhoza kulankhula zambiri za ubwino wake.
- Njira imeneyi ndi njira yosagwirizanirana ndi mankhwala, motero, mwayi wopita kuchipatala ndi wochepa.
- Pochiza, nthawi zina njira imodzi ndi yokwanira.
- Kuchotsa matenda omwe ali ndi kachilomboka kumapita msanga, mopanda magazi, mopanda phokoso.
- Pambuyo pa opaleshoni ya laser, palibe zipsera zatsalira.
Pogwiritsa ntchito mapuloteni, PDT imagwiritsidwa ntchito kuthetsa mazenera a kukula ndi malo osiyanasiyana. Basaliomas ndi chotupa chodziwika kwambiri kwa ma laser. Mlingo wa photosensitizer ndi kuwala kwa wodwala aliyense amasankhidwa payekha.
