I-Para-aminobenzoic acid

I-Para-aminobenzoic acid (PABA) yinto yemvelo. Kuvame ukusetshenziswa emikhiqizweni evikela ilanga. I-PABA kwesinye isikhathi ibizwa ngokuthi yi-vitamin Bx, kepha ayiyona ivithamini leqiniso.

Lo mbhalo ukhuluma ngokusabela kwe-PABA, njengokuphuza ngokweqile nokuphendula okwaliwa. Ukweqisa ngokweqile kwe-PABA kwenzeka lapho othile esebenzisa okungaphezu kwenani elijwayelekile noma elinconywayo lale nto. Lokhu kungaba ngengozi noma ngenhloso.

Uma isetshenziswa ngokufanele, imikhiqizo equkethe i-PABA inganciphisa izehlakalo zezinhlobo eziningana zomdlavuza wesikhumba.

Lo mbhalo ungowolwazi kuphela. UNGAYisebenzisi ukwelapha noma ukuphatha ukuvezwa kobuthi uqobo. Uma wena noma umuntu onaye unokuchayeka, shayela inombolo yakho ephuthumayo yasendaweni (njenge-911), noma isikhungo sendawo sakho sobuthi singafinyelelwa ngqo ngokushayela ucingo lwasimahla lwe-Poison Help hotline (1-800-222-1222) kusuka noma yikuphi e-United States.

I-Para-aminobenzoic acid (eyaziwa nangokuthi yi-4-aminobenzoic acid) ingaba yingozi kakhulu.

I-PABA isetshenziswa emikhiqizweni ethile yokuvikela ilanga kanye nemikhiqizo yokunakekelwa kwesikhumba.

Kungenzeka futhi ngokwemvelo kulokhu kudla:

• Imvubelo kaBrewer
• Isibindi
• Ama-Molasses
• Amakhowe
• Isipinashi
• Izinhlamvu eziphelele

Eminye imikhiqizo ingaqukatha ne-PABA.

Izimpawu zokuphendula okweqile ku-PABA noma i-PABA ukudlula ngokweqile zifaka:

• Uhudo
• Isiyezi
• Ukucasulwa kwamehlo uma kuthinta amehlo
• Imfiva
• Ukuhluleka kwesibindi
• Isicanucanu, ukuhlanza
• I-Rash (ekuphenduleni komzimba)
• Ukuphelelwa umoya
• Ukuphefumula kancane
• Isiphukuphuku (ukushintsha ukucabanga nokunciphisa izinga lokuqonda)
• I-Coma (ukungaphenduli)

Qaphela: Ukuphendula okuningi kwe-PABA kungenxa yokusabela okweqile, hhayi ukweqisa.

Funa usizo lwezokwelapha ngokushesha. UNGAKHONZI ukwenza umuntu alahle ngaphandle kokuthi ulawulwe ubuthi noma umnakekeli wezempilo ekutshela ukuthi wenze kanjalo. Uma ikhemikhali lisesikhunjeni noma emehlweni, gxuma ngamanzi amaningi okungenani imizuzu eyi-15.

Uma ikhemikhali ligwinyiwe, nikeza lowo muntu amanzi noma ubisi khona lapho, ngaphandle kwalapho umhlinzeki ekutshela ukuthi ungalethi. UNGANIKI lutho ukuphuza uma umuntu enezimpawu ezenza kube nzima ukugwinya. Lokhu kufaka hlanza, ukudlikizela, noma ukwehla kwezinga lokuqapha.

Lungisa lolu lwazi:

• Iminyaka yomuntu, isisindo, nesimo
• Igama lomkhiqizo (izithako namandla, uma kwaziwa)
• Isikhathi sasigwinywa noma sisetshenziswe esikhunjeni
• Inani eligwinyiwe noma elisetshenzisiwe esikhunjeni

Isikhungo sakho sendawo sokulawula ubuthi singafinyelelwa ngqo ngokushayela inombolo yocingo yamahhala kazwelonke (1-800-222-1222) kusuka noma yikuphi e-United States. Le nombolo yocingo kazwelonke izokuvumela ukuthi ukhulume nochwepheshe bokufaka ushevu. Bazokunikeza eminye imiyalelo.

Le yisevisi yamahhala futhi eyimfihlo. Zonke izikhungo zokulawula ubuthi e-United States zisebenzisa le nombolo kazwelonke. Kufanele ushaye uma unemibuzo mayelana nobuthi noma ukuvimbela ubuthi. Akudingeki ukuthi kube yisimo esiphuthumayo. Ungashayela nganoma yisiphi isizathu, amahora angama-24 ngosuku, izinsuku eziyi-7 ngeviki.

Thatha isiqukathi uhambe naso uye esibhedlela, uma kungenzeka.

Umhlinzeki uzolinganisa futhi aqaphe izimpawu ezibalulekile zomuntu, kufaka phakathi izinga lokushisa, ukushaya kwenhliziyo, izinga lokuphefumula, nomfutho wegazi.

Ukuhlolwa okungenziwa kufaka phakathi:

• Ukuhlolwa kwegazi nomchamo
• I-x-ray yesifuba
• I-ECG (i-electrocardiogram, noma ukulandelwa kwenhliziyo)

Ukwelashwa kungafaka:

• Kwenziwe amalahle ngomlomo noma ngeshubhu ngamakhala angene esiswini
• Ukwesekwa kokuphefumula, kufaka phakathi i-oxygen, ishubhu elingena emlonyeni kuya emphinjeni, nomshini wokuphefumula
• Uketshezi ngomthambo (ngu-IV)
• Imithi yokwelapha izimpawu

Ukuthi umuntu wenza kahle kangakanani kuncike enanini likashevu agwinyiwe nokuthi ukwelashwa kusheshe kutholakale kanjani. Usizo lwezokwelapha olusheshayo lunikezwa, kuba ngcono ithuba lokululama.

Ukugwinya imikhiqizo yesikrini selanga equkethe i-PABA kuyaqabukela kubangele izimpawu, ngaphandle kwemithamo emikhulu kakhulu. Abanye abantu bangaphikisana ne-PABA.
