Iyeza zanamhlanje zihlala zikhula. Umzekelo ocacileyo wolu ngonyango we-photodynamic. Le ndlela yokonyango iye yaphuhliswa ixesha elide, kodwa isetyenziswa kuphela kwiminyaka embalwa edlulileyo. Ngenxa yobuchule bayo, unyango lwe-photodynamic lufumene isicelo kumaqela amaninzi eyeza.
Ziziphi iimeko ezahlukileyo kunye neenzuzo zonyango lwe-laser photodynamic?
Isiseko sonyango lwe-photodynamic yi-photosensitizers. Lawa mayeza akhethekileyo anokukhathazeka kakhulu ekukhanyeni. Ngenxa yempembelelo kubo ngokuncediswa kwamaza laser obuthile ubude, imiphumo efunekayo ifumaneka.
Ukubeka nje, i-drug-photosensitizer ifakwe emzimbeni. Zonke iindlela zanamhlanje aziyizo zityhefu kwaye zingakwazi ukuqokelela ngokukhawuleza kwizicubu ezichaphazelekayo. Emva koko, i-apparatus for therapy photodynamic isetyenziswa. Ingumthombo we-laser radiation, ovumela ukulawula ubude kunye nobukhulu bamagagasi. Ngethuba loqhagamshelwano kunye ne-laser, i-photosensitizer ijabule, ukusabela kwe-photochemical kuqala, ngenxa yendlela i-radicals yamahhala eyenziwa ngayo. Ezi zilandelayo zichaphazelekayo kwiiseli ze-neoplasms, kwaye zincinci. Kwindawo ye-tumor emva kwenkqubo, i-tissue ephathekayo iphilile.
Ulwaphulo lwePhotodynamic luboniswa kwiingxaki ezinjalo:
- i melanoma ;
- Umhlaza wesikhumba (i-squamous, isalence cell, metatypic);
- iimvumi ezichasene nezinye iindlela zokwelapha;
- Izixhobo ezingenakusebenza (ezihlala zihlala kwindawo ezilukhuni).
Ngamanye amaxesha unyango lwe-photodynamic luba yindlela kuphela yokunyanga isigulane. Ewe, le ndlela ayilula, kodwa iziphumo ezibonisa ukuba zifanelekile ngenhlonipho.
Uphuhliso lwePhotodynamic kwi-oncology
Ekuqaleni, le ndlela yaphuhliswa ngokukodwa kunyango lomhlaza. Unokuthetha ezininzi malunga neenzuzo zayo.
- Le ndlela yindlela yokungathintana ngayo yonyango, ngokulandelanayo, ithuba lokungenwa kwintsholongwane emzimbeni lincinci.
- Ukunyanga, ngamanye amaxesha enye inkqubo inokwaneleyo.
- Ukususwa kwezicubu ezikhuselweyo zidlula ngokukhawuleza, zingenagazi, zingenabuhlungu.
- Emva kokusebenza kwe-laser, akukho zicatshulwa ezisele.
Kwi-oncology, i-PDT isetyenziselwa ukulawula i-neoplasms of size and different areas. I-Basaliomas yimilambo evelele kakhulu kwiimilasi ze-laser. Umthamo we-photosensitizer kunye nokukhanya kwesigulane ngasinye sikhethwe ngabanye.
