Thandizo la Photodynamic (PDT) ndi njira yothandizira, yomwe imagwiritsidwa ntchito makamaka pofuna kuchiza matenda otupa, komanso matenda ena a dermatological ndi opatsirana. Pakalipano, adakali pa siteji yophunzira zachipatala, chitukuko ndi chitukuko, koma amagwiritsidwa ntchito mwakhama, kunja kwina komanso ndi ife.
Njira yothetsera photodynamic incology
PDT pochiza khansa ndi yotsika mtengo, njira yofatsa komanso yothandiza, yomwe imakuthandizani kuti muchotse mitundu yosiyanasiyana ya zotupa zowopsya - zoyamba, zowonongeka, zowonjezereka. Momwemo, mankhwala a photodynamic akuwonetsedwa kwa:
- khansa ya khansa , kansa ya khungu;
- zilonda za khansa zam'mimba, zowakomera pamlomo, zilembo zam'mimba, zikopa;
- khansara yamapapo, bronchi, trachea;
- maonekedwe oopsa a chiberekero, chifuwa, mawere, mimba, m'mimba, chikhodzodzo, ndi zina.
Njirayi imachokera ku chiwonongeko cha maselo otupa chifukwa cha mphamvu ya mpweya wa oxygen, yomwe imapangidwa pachithunzi cha photochemical reaction. Zomwe ziyenera kutero ndizochepa za wavelengths (zofiira), mpweya umene umapezeka nthawi zonse m'thupi, komanso zinthu zapadera - photosensitizers.
Photosensitizers ndi zinthu zojambula zithunzi zomwe zimatha kuzindikira ndi kutumiza mphamvu zowala. Zojambula zamtundu wapadera zimayikidwa mu thupi la wodwala (mwachangu, pamagwiritsidwe ntchito, pamlomo), ndipo amatha kusonkhanitsa maselo a khansa, pomwe samangokhala m'maselo abwino.
Kenaka, motsogoleredwa ndi kuwala, mpweya wa khansa umapita ku malo apadera, momwe amayamba kuwonongera zinthu za mkati mwa maselo otupa. Monga gwero la kuwala, monga lamulo, makina a laser amagwiritsidwa ntchito. Choncho, chotupacho chikuphedwa. Izi zimatenga masabata awiri mpaka 3. Thandizo la Photodynamic likhoza kuphatikizidwa ndi radiotherapy kapena chemotherapy, komanso njira zopaleshoni, zomwe zimapangitsa kuti pakhale zotsatira zabwino pochiza khansa.
Pali chithandizo cha photodynamic mu oncology ndi zina zotsutsana:
- matenda a impso ndi chiwindi ntchito;
- Matenda a m'mtima (kubwezeretsa maliro);
- mimba ndi lactation;
- hypersensitivity kwa photosensitizer.
Thandizo la Photodynamic mu stomatology
Posachedwapa, PDT ikufala kwambiri pochiza matenda a mano ndi ching'ombe, zomwe ndizo:
- nthawi ;
- gingivitis;
- alveolitis;
- chosowa;
- amalephera.
Mothandizidwa ndi photosensitizer ndi kuyendetsedwa ndi laser mtanda, bwinobwino disinfection ikuchitika, omwe ndi njira yabwino yoyenera mankhwala ochizira mankhwala pochiza matenda omwe alipo.
Thandizo la photodynamic mu cosmetology

Zithunzi zojambulajambula zomwe zimagwiritsidwa ntchito pakhungu m'madera ovuta zimaphatikizapo maselo osalongosoka komanso akale (monga momwe zilili m'madera omwe alibe mphamvu). Chifukwa cha photochemical reaction pogwiritsa ntchito laser, imfa ya maselo owonongeka amapezeka. Pamodzi ndi izi, ndondomeko imatsogolera kugawidwa kwa maselo a tsinde la khungu lachitsulo kuti lilowetse maselo omwe awonongeke, ndipo kusinthika kwa collagen kumachitika.
Thandizo la photodynamic mu ophthalmology
Thandizo la Photodynamic ndilo njira yothetsera opaleshoni ya laser pakuchipata matenda ena a maso. Makamaka, polepheretsa kukula kwa mitsempha ya m'magazi, njira iyi ikhoza kuteteza kupititsa patsogolo kwa dothi lochedwa la retinal kuchepa.
Thandizo la Photodynamic - zotsatira
Njira yokhayo yotsatila njirayo ndi yokhudzidwa kanthawi kochepa kuunika. Pachifukwa ichi, odwala atatha njira ya PDT ayenera kupeweratu dzuwa.
