I-Photodynamic therapy (PDT) yindlela yokonyango, esetyenziswa ngokuyinhloko ekuphatheni izicubu ezimbi, kunye nezinye izifo ezise-dermatological kunye nezifo ezithintekayo. Njengamanje, usesezingeni lesifundo sekliniki, uphuhliso kunye nophuculo, kodwa ngokusetyenziswa ngokufanelekileyo nangomsebenzi, nakwamanye amazwe kunye nathi.
Indlela yokwelapha i-photodynamic kwi-oncology
I-PDT kwonyango lomhlaza ayixabisekanga, indlela enobubele kunye neyobuchule, ekuvumela ukuba ulahleke iintlobo ezahlukeneyo zezihlamba ezibi - eziphambili, eziphindaphindiweyo, ezikhoyo. Ngokunjalo, unyango lwe-photodynamic luboniswa ukuba:
- i-melanoma , umdlavuza wesikhumba;
- izilonda zomlomo zomhlaza, umlomo womlomo, i-auricles, iinkophe;
- umhlaza wamaphaphu, i-bronchi, i-trachea;
- iifomu ezinobungozi zomlomo wesibeleko, i-vulva, isifuba, isisu, isisu, isisu, njl.
Le ndlela isekelwe kukutshatyalaliswa kweeseli zesisu ngenxa yempembelelo yeefomu ezisebenzayo zomoya-mpilo, ezenziwe ngexesha lokuphendula kwe-photochemical. Iimpawu eziyimfuneko zale mpendulo zikhawulezileyo zeevelengths (zobomvu) ezithile, i-oksijeni, ehlala ikhona kwizicubu zomzimba, kunye nezinto ezizodwa - iifotoensitizers.
Ama-photosensitizers zizinto ezibonakalayo ezibonakalayo ezinokukwazi ukubona nokuthumela amandla okukhanya. Iifoto ezifake iifoto ezizodwa zijojowe emzimbeni wesigulane (ngokukhawuleza, ngokusetyenziswa kwesicelo, ngomlomo), kwaye ziqokelela ngokukhethekileyo kumaseli esifo somhlaza, ngelixa zingaphelanga kwiiseli eziphilileyo.
Emva koko, ngaphantsi kwefuthe lokukhanya, i-oksijeni kwiishukela zomhlaza idlulela kwindawo ekhethekileyo esebenzayo, apho iqala ukuchaphazela ngokutsha izakhiwo zangaphakathi zeeseli zesisu. Njengomthombo wokukhanya, njengommiselo, ukufakwa kwelaser kusetyenziswa. Ngaloo ndlela, i-tumor iyabulawa. Le nkqubo ithatha malunga neveki ezi-2 ukuya kwezi-3. Ulwaphulo lwe-Photodynamic lunokudibaniswa ne-radiotherapy okanye i-chemotherapy, kunye neendlela zokugqirha, ezivumela ukuphumeza iziphumo ezibalulekileyo kunyango lomhlaza.
Kukho unyango lwe-photodynamic kwi-oncology kunye nokunye okuchasayo:
- ukukhubazeka kwesifo senhliziyo kunye nesibindi;
- Izifo ze-Cardiovascular (isingeniso sesigaba);
- ukukhulelwa kunye nokuhlaselwa;
- i-hypersensitivity kwi-photosensitizer.
I-Photodynamic therapy kwi stomatology
Kutshanje, i-PDT iya kuba yinto eqhelekileyo kunyango lwezilwanyana kunye namazinyo, oku:
- i-periodontitis ;
- gingivitis;
- alveolitis;
- i-discolorite;
- i-caries.
Ngoncedo lwe-photosensitizer kwaye kusebenze ngethamsanqa ye-laser, i-disinfection epheleleyo yenziwa, eyona ndlela ifanelekileyo kwiyeza-antibiotics kunyango lwezonyango ezikhoyo.
I-Photodynamic therapy kwi-cosmetology
Indlela yokwelapha i-photodynamic isetyenziswa kakhulu kunyango lwe-acne, nakweminye imimandla ye-cosmetology kunye ne-dermatology-ukukrazula iimpawu ze-couperose, i-rosacea, i-hyperpigmentation, i-photoaging, i-keratoma, i-psoriasis, i-vitiligo, i-mycoses.
Iifayili-iifotensitizers ezisetyenziswa kwesikhumba kwiindawo ezinengxaki ziqokelela kwiiseli ezinokungahambiyo kunye namandulo (njengokuba kuninzi kwindawo ezingenamandla). Ngenxa yeempendulo ze-photochemical phantsi kwesenzo se laser, ukufa kweeseli ezonakalisiweyo kwenzeka. Ngoku kunye nale, inqubo ikhokelela ekuvuseleleni ukwahlula kweeseli ezinamaqabunga e-basal ungqimba lwesikhumba ukutshintsha iiseli ezonakalisiweyo, kunye nokuvuselelwa kwemveliso ye-collagen eyenzekayo.
I-Photodynamic therapy kwi-ophthalmology
Ulwaphulo lwe-Photodynamic luhlobo oluthile lokuhlinzwa otyunjwa kwilayisensi ekhatyweni kwezifo ezithile zamehlo. Ngokukodwa, ngokunciphisa ukukhula kwemithambo yegazi, le ndlela iyakwazi ukuthintela ukuqhubela phambili kohlobo olumanzi lokuhlaselwa kwe-retinal.
Uphulo lwePhotodynamic - iziphumo ezibi
Impembelelo yecala kuphela le ndlela yindlela yokwenza ukukhanya okwexeshana. Kule nkalo, izigulane emva kwenkqubo ye-PDT kufuneka ifike ixesha lokuphepha ukukhanya kwelanga.
