Yini i-14C-Urea (Indlela Yomlomo): Ukusetshenziswa, Umthamo, Imiphumela Eceleni Nokunye

I-14C-Urea iyimithi ekhethekile yokuxilonga esetshenziselwa ukuthola amagciwane athile esiswini abizwa ngokuthi i-Helicobacter pylori (H. pylori). Lokhu akuyona imithi yokwelapha - iyithuluzi lokuhlola elisiza odokotela ukuthi bathole ukuthi ngabe unayo yini leli gciwane elivamile elingabangela izinkinga zesisu.

Ukwenza ngcono ukuhlolwa kukwenza uphuze isixazululo esiqukethe i-urea elinelebula elinomaka ophephile we-radioactive. Uma amagciwane e-H. pylori ekhona esiswini sakho, aqeda i-urea futhi akhiqize i-carbon dioxide oyiphefumulayo, engabe isilinganiswa.

Yini i-14C-Urea Esetshenziselwa Yona?

I-14C-Urea isetshenziselwa ngokuqondile ukuxilonga izifo ze-H. pylori esiswini sakho. Leli gciwane livamile ngokumangalisayo futhi lingabangela izilonda zesisu, i-gastritis (ukuqubuka kwesisu), nezinye izinkinga zokugaya ukudla.

Udokotela wakho angase ancome lolu vivinyo uma unezinhlungu zesisu eziqhubekayo, ukusha kwenhliziyo, isicanucanu, noma ezinye izimpawu ezisikisela ukuthi une-H. pylori infection. Lolu vivinyo lusiza ngoba lungathola izifo ezisebenzayo, hhayi nje ukuthi ngabe wake wavezwa yini amagciwane ngaphambili.

Ngezinye izikhathi odokotela basebenzisa lolu vivinyo ukuhlola ukuthi ngabe ukwelashwa kwe-H. pylori kusebenze ngempumelelo yini. Kuthathwa njengenye yezindlela ezinembile kakhulu zokuqinisekisa ukuthi ngabe amagciwane asakhona yini ngemuva kokuqeda ukwelashwa ngama-antibiotic.

Isebenza Kanjani i-14C-Urea?

I-14C-Urea isebenza ngenqubo ehlakaniphile yezinto eziphilayo esebenzisa indlela amagciwane e-H. pylori aziphatha ngayo. Amagciwane akhiqiza i-enzyme ebizwa nge-urease, eqeda i-urea ibe yi-ammonia ne-carbon dioxide.

Uma uphuza isixazululo se-14C-Urea, siya esiswini sakho. Uma amagciwane e-H. pylori ekhona, aqeda ngokushesha i-urea enelebula. I-carbon dioxide ekhiqizwayo iqukethe umaka we-radioactive, otheni uwuphefumule ngamaphaphu akho.

Abahlinzeki bezempilo baqoqa amasampula akho okuphefumula ngezikhathi ezithile futhi balinganise i-carbon dioxide enomsakazo. Uma kutholakala amanani amakhulu, kuqinisekisa ukuthi amagciwane e-H. pylori aphila ngempela esiswini sakho.

Kufanele Ngiyithathe Kanjani i-14C-Urea?

Kuzodingeka ukuthi uzile ukudla okungenani amahora angu-6 ngaphambi kokuthatha i-14C-Urea, okusho ukuthi akukho ukudla noma iziphuzo ngaphandle kwamanzi. Umhlinzeki wakho wezempilo uzokunikeza imiyalelo ethile mayelana nokuthi uyeke nini ukudla nokuphuza.

Uvivinyo ngokuvamile luhlanganisa ukuphuza inani elincane le-14C-Urea solution elixutshwe namanzi. Uzoziphuza le ngxube ngokushesha, ngokuvamile ngemizuzu embalwa. Isixazululo ngokuvamile asinawo ukunambitheka noma sinokunambitheka okuncane kakhulu.

Ngemva kokuphuza isixazululo, kuzodingeka ukuthi unikeze amasampula okuphefumula ngokuphefumulela emasakeni akhethekile okuqoqa noma amashubhu. Lawa masampula ngokuvamile aqoqwa ngemizuzu engu-10, 20, kanye no-30 ngemva kokuphuza isixazululo. Kubalulekile ukulandela isikhathi ngqo njengoba umhlinzeki wakho wezempilo ekuyala.

Ngesikhathi sokulinda, kufanele uhlale buthule futhi ugweme imisebenzi eqinile yomzimba. Ezinye izindawo zingase zikwenze ulale phansi noma uphumule esihlalweni esinethezekile phakathi kokuthathwa kokuphefumula.

Kufanele Ngiyithathe Isikhathi Esingakanani i-14C-Urea?

I-14C-Urea iwukuhlolwa okukodwa kokuxilonga, hhayi umuthi oqhubekayo. Inqubo yonke yokuhlola ngokuvamile ithatha imizuzu engaba ngu-30 kuya kwengu-60 kusukela ekuqaleni kuya ekugcineni.

Uzoziphuza isixazululo kanye kuphela ngesikhathi sakho sokuvakasha. Ngemva kokuhlinzeka ngamasampula okuphefumula adingekayo, ukuhlolwa kuqediwe. Akunasidingo sokuthatha imithamo eyengeziwe noma ukuqhubeka nanoma yikuphi ukwelashwa okuhlobene ne-14C-Urea ngokwayo.

Uma imiphumela yakho yokuhlolwa ikhombisa ukutheleleka nge-H. pylori, udokotela wakho uzobe esenquma ukwelashwa okufanele ngama-antibiotics. Ungase udinge ukuphinda ukuhlolwa kokuphefumula emasontweni noma ezinyangeni ezimbalwa kamuva ukuze uqinisekise ukuthi ukwelashwa kusebenze ngempumelelo.

Yiziphi Imiphumela Eceleni ye-14C-Urea?

I-14C-Urea ngokuvamile iphephile kakhulu futhi ayinayo imiphumela emibi. Abantu abaningi ababi naziphendukelo ezingezinhle ngesikhathi noma ngemuva kokuhlolwa.

Imiphumela emibi evame kakhulu imnene futhi yesikhashana. Lokhu kungabandakanya:

• Ukungazizwa kahle kancane, ikakhulukazi uma uzwela ekuzileni ukudla
• Ukuphatheka kabi kwesisu okuncane
• Isiyezi ngezikhathi ezithile ngenxa yokuzila ukudla
• Ukunambitheka kwensimbi okufushane emlonyeni wakho

Lezi zimpawu ngokuvamile zixazululeka ngokushesha futhi azidingi ukwelashwa. Ukuvezwa kwemisebe evela kulolu hlolojikelele kuphansi kakhulu - ngaphansi kakhulu kwalokho ongakuthola ku-X-ray yesifuba.

Imiphumela emibi ebucayi ayivamile kakhulu. Kodwa-ke, kufanele uxhumane nomhlinzeki wakho wokunakekelwa kwezempilo uma uhlangabezana nokungazizwa kahle okukhulu, ukuhlanza okuqhubekayo, noma yiziphi izimpawu ezingavamile ngemuva kokuhlolwa.

Ngizothola nini Imiphumela Yami Yokuhlolwa?

Imiphumela yokuhlolwa kwe-14C-Urea ivamise ukutholakala phakathi kwezinsuku ezimbalwa kuya evikini elilodwa, kuye ngesikhathi sokucubungula elebhu yesikhungo sakho sezempilo. Ezinye izikhungo ezinkulu zezokwelapha zingase zibe nemiphumela etholakala ngokushesha.

Umhlinzeki wakho wezempilo uzokuthinta ngemiphumela futhi axoxe ngezinyathelo ezilandelayo. Uma i-H. pylori itholakele, bazoncoma izinketho zokwelashwa ezifanele. Uma ukuhlolwa kungalungile, bangase bahlole ezinye izimbangela zezimpawu zakho.
