IPara-aminobenzoic acid

IPara-aminobenzoic acid (PABA) yinto yendalo. Ihlala isetyenziswa kwiimveliso ze-sunscreen. I-PABA ngamanye amaxesha ibizwa ngokuba yi-vitamin Bx, kodwa ayisiyo vithamini yokwenyani.
Eli nqaku lixoxa ngokusabela kwi-PABA, njengokudlula ngaphezulu kunye nokuphendula okwaliwa. Ukugqithisa kwe-PABA kwenzeka xa umntu esebenzisa ngaphezu kwexabiso eliqhelekileyo okanye elicetyiswayo le nto. Oku kunokuba ngengozi okanye ngenjongo.
Xa isetyenziswe ngokufanelekileyo, iimveliso ze-PABA ezinokunciphisa imeko zinokunciphisa iimeko ezahlukeneyo zomhlaza wolusu.
Eli nqaku lelolwazi kuphela. SUKUYISETYENZISE ukunyanga okanye ukulawula ukubonakaliswa kwetyhefu uqobo. Ukuba wena okanye umntu onaye une-exposure, fowunela inombolo yakho yongxamiseko yendawo (enje nge-911), okanye iziko lakho lendawo yetyhefu linokufikelelwa ngokuthe ngqo ngokutsalela umnxeba kwinombolo yasimahla yoNcedo lweTyhefu (1-800-222-1222) naphi na eUnited States.
IPara-aminobenzoic acid (ekwabizwa ngokuba yi-4-aminobenzoic acid) inokuba yingozi kwisixa esikhulu.
I-PABA isetyenziswa kwi-sunscreen ethile kunye neemveliso zokhathalelo lolusu.
Inokwenzeka ngokwendalo koku kutya:
- Igwele leBrewer
- Isibindi
- Imibala
- Amakhowa
- Ispinatshi
- Amazimba
Ezinye iimveliso zinokuqulatha iPABA.
Iimpawu zokungabikho komzimba kwi-PABA okanye kwi-PABA ukugqithisa kubandakanya:
- Urhudo
- Ukuba nesiyezi
- Ukucaphuka kwamehlo ukuba ichukumisa amehlo
- Ifiva
- Ukungaphumeleli kwesibindi
- Isicaphucaphu, ukugabha
- Irhash (xa kukho ukungahambi kakuhle komzimba)
- Ukuqhawukelwa ngumphefumlo
- Ukuphefumla kancinci
- Isiphukuphuku (ukutshintsha ukucinga kunye nokwehla kwenqanaba lokuqonda)
- Coma (ukungaphenduli)
Qaphela: Uninzi lweempendulo ze-PABA zibangelwa kukungaziphathi kakuhle.
Funa uncedo lwezonyango kwangoko. MUSA ukumenza umntu aphose ngaphandle kokuba ulawula ityhefu okanye akuxelele ukuba umboneleli wezempilo. Ukuba imichiza isesikhumbeni okanye emehlweni, coca amanzi amaninzi ubuncinci imizuzu eli-15.
Ukuba imichiza iye yaginywa, mnike amanzi okanye ubisi kwangoko, ngaphandle kokuba umboneleli akakuxeleli. SUKUNIKA nantoni na ukuba isele xa umntu eneempawu ezenza ukuba kube nzima ukuginya. Oku kubandakanya ukugabha, ukuxhuzula, okanye inqanaba lokuncipha lokuqaqamba.
Ngaba olu lwazi lukulungele:
- Ubudala bomntu, ubunzima, kunye nemeko
- Igama lemveliso (izithako kunye namandla, ukuba kuyaziwa)
- Ixesha laliginyiwe okanye lisetyenziswe kulusu
- Inani liginyiwe okanye lisetyenziswe kulusu
Iziko lakho lokulawula ityhefu lingafikelelwa ngokuthe ngqo ngokutsalela umnxeba wenombolo yasimahla yasimahla kuTyhefu (1-800-222-1222) naphi na e-United States. Le nombolo yesizwe iya kukuvumela ukuba uthethe neengcali kwiityhefu. Baza kukunika eminye imiyalelo.
Le yinkonzo yasimahla neyimfihlo. Onke amaziko olawulo lwetyhefu aseMelika asebenzisa le nombolo yesizwe. Kuya kufuneka ubize ukuba unemibuzo malunga netyhefu okanye ukuthintela ityhefu. AKUFUNI ukuba ibe yingxakeko. Ungatsalela umnxeba nangasiphi na isizathu, iiyure ezingama-24 ngosuku, iintsuku ezisi-7 ngeveki.
Thatha isikhongozeli uhambe naso esibhedlele, ukuba kunokwenzeka.
Umboneleli uya kulinganisa kwaye abeke esweni iimpawu ezibalulekileyo zomntu, kubandakanya iqondo lobushushu, ukubetha kwentliziyo, inqanaba lokuphefumla, kunye noxinzelelo lwegazi.
Uvavanyo olunokwenziwa lunokubandakanya:
- Uvavanyo lwegazi kunye nomchamo
- I-x-ray yesifuba
- I-ECG (i-electrocardiogram, okanye ukulandelwa kwentliziyo)
Unyango lunokubandakanya:
- Ukusebenza kwamalahle ngomlomo okanye ngetyhubhu ngempumlo ungene esiswini
- Ukuxhasa ukuphefumla, kubandakanya ioksijini, ityhubhu emlonyeni ukuya emqaleni, kunye nomatshini wokuphefumla
- Ulwelo ngomthambo (ngo-IV)
- Iyeza lokunyanga iimpawu
Ukusebenza kakuhle komntu kuxhomekeke kubungakanani betyhefu aginye kunye nendlela unyango olukhawulezileyo olufunyanwa ngayo. Uncedo olukhawulezileyo lwezonyango lunikwa, ngcono ithuba lokuchacha.
Ukuginya iimveliso ze-sunscreen eziqukethe i-PABA kunqabile ukuba zibangele iimpawu, ngaphandle kweedosi ezinkulu kakhulu. Abanye abantu banokungabikho komzimba kwi-PABA.
