Ngentwasahlobo, amaphephandaba amaningi abhala izihloko ezixwayisayo mayelana ne-photocarogenesis ne-photoaging. Kodwa, naphezu kwalokhu, izigidi zabantu ziqhubeka nokuhlukumeza "ukufudumala kwelanga." Sifundiswa kusukela ebuntwaneni ukuthi i- sunbathing inhle empilweni. Kodwa labo abachitha isikhathi eside befudumala elangeni, basongelwa nge-photosensitivity. Lesi yisifo esibi, esiholela emiphumeleni eyingozi esikhumbeni sama-ultraviolet.
Kuhle kakhulu ukujabulela ukushisa kwelanga emva kwebusika obubandayo obubandayo! Asifuni ngisho ukukhumbula ukuthi i-ray yelanga iphethe imisebe ye-ultraviolet, okuyinto isitha esikhulu esikhumbeni sethu. Ukuvezwa kwe-Ultraviolet, okuholele ekugugeni isikhumba, akuwona umzimba obonakala ngokuzithobayo. Ngakho-ke, kunzima ngathi ukubona ilanga njengengozi. Ngaphezu kwalokho, ngokumukelwa okulinganiselayo okuthiwa yi-suns baths, kuletha izinzuzo ezibonakalayo emzimbeni. Kodwa ukushisa kwelanga kuzwa kahle. Ukuzwa okuvuthayo okungajabulisi kungakhathaza izinsuku ezimbalwa. Kodwa abantu abaningi bazijwayele futhi bacabange ukungaboni kahle okucasulayo. Futhi kuyize!
Eminyakeni yamuva, abantu abaningi futhi babhekene nenkinga engalindelekile yemiphumela eyingozi esikhumbeni sama-ultraviolet. Ake ucabange ukuthi isimo sezulu sibhakabhaka ngaphandle. I-ray engavamile kuphela ihamba emafwini. Ilanga cishe libonakala lingabonakali, kodwa ngemva kokuhamba emabhaleni esikhumba avela. Itches kanye flakes. Lokhu kwenzeka kaningi kubafazi. Futhi zikhona izizathu zalokhu. Iqiniso liwukuthi lokhu kusabela kubangelwa izinto ezingaphandle eziye zavela noma ngaphansi kwesikhumba. Benza isikhumba siphezulu emisebeni ye-ultraviolet. Lezi zinto zibizwa ngokuthi i-photoreactive noma, ngendlela ehlukile, izithombe ze-photosensitizers. Ikakhulukazi ingakwazi ukubhekana nalezi zindlela, isikhumba, buthakathaka ngokushisa kwelanga. Ama-photosensitizer angabangela ukusabela kwezinhlobo ezimbili - ukusabela kwe-photoallergic nokuphototoxic.
Ngokuvamile isithombe sokungezwani komzimba kubangelwa amafutha nezimonyo ngesisekelo se: amafutha e-sandalwood, amafutha e-bergamot, ama-amber, ama-musk. Noma kunjalo isithombe sokungezwani komzimba singakhipha imithi kanye nama-antibacterial agents. Imisebe ye-ultraviolet ishintsha ukubunjwa kwamakhemikhali okutholakala esikhumbeni. Le nqubo ibangela ukungezwani komzimba. Futhi emva kwesigamu sehora sokuchayeka ekukhanyeni kwe-ultraviolet, ukungezwani komzimba kungasakazeka ezindaweni ezivaliwe zesikhumba.
Kuyaziwa ukuthi ukugxila ngokujulile emisebeni ye-ultraviolet kubhubhisa amangqamuzana ezicubu eziphilayo. Yilokho okwenzekayo ngokuphendula kwe-phototoxic. Into esesikhumba yamukela imisebe ye-ultraviolet, ethinta amangqamuzana asemzimbeni omakhelwane. Amaseli anjalo ekugcineni afa, abangela izinkinga eziningi. Ukuphendula okunjalo kungabonakalisa kokubili ngokushesha, futhi emahoreni ambalwa. Lesi sifo esiyinkimbinkimbi, ngokungafani nokushisa kwelanga, singaziveza isikhathi eside. Ngezinye izikhathi iminyaka eminingana. Ngeshwa, abantu abanezifo zesikhumba bathinteke ikakhulukazi ukuphendula kwe-photoreactive. Efana ne-acne, i-psoriasis, i-herpes, i-eczema.
Ku-photosensitization - emva kokuhlukunyezwa kwezimonyo nokushisa kwelanga, kuvela izinkinga eziningi ezinzima. Lezi zingase zibe izimpande ezinzima zesikhumba (i-photodermatitis enzima). Isibonelo: ukubukeka kwamabhalane, ukuvuza nokushaya, ukubomvu okwenziwe okwehliswayo, ukugujwa kokushisa kwelanga. Futhi izithombe ze-photosensitizers zingabangela izifo zesikhumba ezingapheli. Ukuholela ekugugeni kwayo ngaphambi kwesikhathi futhi ngisho nezifo ezingokwemvelo.
Izifundo zibonise ukuthi izingxenye ze-photoreactive zingatholakala ezintweni ezijwayelekile kithi. Kungaba izidakamizwa, insipho ye-antibacterial kanye nemikhiqizo ehlukahlukene yezimonyo. Izidakamizwa eziningana nazo zinezithombe ze-photosensitizing. Isibonelo, ama-antibiotic (tetracycline), izidakamizwa ezingezona izidakamizwa ezingezokuvuvukala, ama-sulfonylamide, ama-antihistamine. Kuyaziwa ukuthi ukukhishwa kwesikhumba sikaSt. John kuqukethe i-hypericin, enomphumela wokucindezeleka. Ngenxa yalokhu, izithasiselo zokudla kanye no-St. John's wort extract zathandwa. Maye, lokhu kukhishwa nakho kuyi-photosensitizer.
Yiqiniso, ukuba khona kwezithombe ze-photosensitizing akuholeli ku-photodermis kubo bonke abantu. Ngokuvamise kakhulu kuthinta abantu abanekhanda elincane elibomvu elibomvu. Kodwa abantu abanobumnyama, nabo, abakwazi ukuzizwa bephephile ngokuphelele. Ikakhulukazi uma uhlala elangeni isikhathi eside.
Amathuba okuphendula kwe-phototoxic akhula emazwini alandelayo:
- Uma isikhumba sithinteka yi-retinoids. Ama-retinoids asetshenziselwa ukwelashwa kwe-acne nokuvuselelwa kwesikhumba. Basiza ukuphulukisa amangqamuzana esikhumba efile futhi bawavuselele. Kodwa isikhumba sokuqothula singaphansi kokukhanya okukhulu kwe-ultraviolet ukukhanya. Ngakho-ke, uma ukwelapha ama-retinoids, kufanele usetshenziswe isikrini selanga. Lokhu kuzovimbela ukugqotshwa okungalingani.
- Ngemuva kwenqubo yokuhlunga, ukukhishwa kwe-stratum corneum kwenzeka. Ukukhishwa kwe-Chemical, ikhaya elibhekene nezikhwama kanye nokupholisa laser kunomthelela ekwandiseni ukukhanya ekukhanyeni kwe-ultraviolet. Ngaphezu kwalokho, emva kwalolu hlelo, ama-melanocytes abangela ukuguqulwa kwe-hyperpigmentation kusebenza. Kulesi simo, ukuba khona kwe-photosensitizer kunciphisa umphumela wama-protective agents.
- Izimonyo zamasuku eziqukethe i-polyunsaturated fatty acids, zithandwa kakhulu. Iqeda ukucwenga nokomile kwesikhumba. Kunciphisa ukusabela okuvuvukala. Ibuyisela izakhiwo zokuvimbela isikhumba. Noma kunjalo, i-polyunsaturated fatty acids ine-drawback enkulu. Ngaphansi kwethonya elangeni, ziyi-oxidized. Imikhiqizo ye-oxidation eyingozi iyakhiwa. Kubandakanya ama-oksijeni asebenzayo, okuyi-toxin yesikhumba. Futhi ngezenzo ezinkulu ze-ultraviolet, i-oxidation yimbi kakhulu. Yini engabangela ukuphendula okunamandla kwe-phototoxic.
- Isizathu se-phototoxic ukusabela kungenziwa inqubo ye-tattoo. Nge-tattoo nokuzenzela okuhlala unomphela, ingilazi enomunyu we-cadmium ingasetshenziswa. Lokhu usawoti uhlukile kwezakhiwo ze-photosensitizing.
- Okumangalisa ukuthi, amanye ama-sunscreen angeke avikele isikhumba elangeni, kodwa aqalise ukuphendula okubonakalayo. Isizathu salokhu yi-paraamino-benzoic acid (PAVA), okuyingxenye ukhilimu. Funda ngokucophelela ukwakhiwa kokhilimu kuphakheji. Ngendlela, eNtshonalanga le asidi ingabandakanywa ekufomeni.
- Izinto eziphathekayo ziqukethe amafutha abalulekile. Ngakho-ke, landela ngokucophelela ukusabela isikhumba ngemuva kwezinqubo usebenzisa amafutha abalulekile.
Njengoba ubona, inqwaba yezimonyo nemithi iqukethe izinto ezingase zibe yingozi kwesikhumba esibuthakathaka. Futhi ingozi yokuthola i-photoderma ayiyona encane kakhulu. Umthelela obala ngokukhethekile wezithombeensitizers entwasahlobo. Lapho izigidi zabesifazane zitholakala emkhunjini nase-avitaminosis, isikhumba sibhekene nemiphumela eyingozi. Ngokuphishekela ubuhle, abesifazane abathandekayo abalaleli iseluleko se-cosmetologists. Ngemuva kwezinqubo, ukuhlunga nokugaya kubhekwa njengokungabonakali usebenzisa i-sunscreen. Futhi ikakhulukazi hhayi ukugqoka izigqoko ezinemiphetho emikhulu. Ngokuphambene nalokho, bazifaka esikhundleni selanga lesentwasahlobo, bengabonakali ngomthelela ongenamusa wemisebe ye-ultraviolet.
Ngeshwa, i-photodermatitis ingahle ilinde noma yimuphi umuntu. Hhayi kuye ngokuthi ucansi nombala wesikhumba. Ngakho-ke, unakekele isikhumba sakho esiyigugu kusengaphambili:
- Kubalulekile ukuthatha ngokungathí sina izixwayiso odokotela ngezingozi zemisebe ye-ultraviolet. I-Fashion for sunburn ihamba, ihlinzeka indlela yombala wesikhumba. Uma ushiya isakhiwo isikhathi eside ngesikhathi sehlobo sasehlobo, kufanele usebenzise izimonyo zelanga. Ungalokothi usebenzise ukhilimu onomsoco phakathi nosuku. I-polyunsaturated fatty acids engena ekubunjweni kwayo elangeni iguqulwa ibe izithombeensitizers. Unganqikazi ukugqoka isigqoko sezinsuku ezikhanyayo zelanga elinamahlombe amakhulu. Ungasebenzisi isikhathi esiningi ngaphansi kwelanga elishisayo.
- Izinqubo zokuqothula ukukhishwa kwesikhumba esidayayo kufanele zenziwe hhayi entwasahlobo nasehlobo, kodwa ekwindla noma ebusika. Uma ungeke wenqabe ukukhishwa, bese ulandela inqubo, zivikele nge-sunscreen, enezinga eliphakeme lokuvikela (SPF> 50).
- Sebenzisa izimonyo ezine-antioxidants: nge-vitamin C, E kanye nama-polyphenols yemifino. Ama-antioxidants ngokwawo ngeke avikele emisebeni ye-ultraviolet. Kodwa basiza ukususa ama-phototakins esikhumbeni.
- Qinisekisa ukuhlinzeka zonke izinyathelo zokuqapha uma uthatha ama-antibiotics, ibuprofen, sulfanilamide, ukukhishwa kwe-wort St. John's wort. Futhi ngokuvamile, akuyona into engafanele ukucacisa nodokotela oya khona mayelana nokuba khona kwama-photosensitizers.
