Ityhefu yelothe yingqokelela yelothe emzimbeni edla ngokukhula ngokuhamba kweenyanga okanye iminyaka

Ilothe yintsimbi eyenzeka ngokwemvelo engenanzuzo emzimbeni.

Ukubonakaliswa kwetyhefu kunokuchaphazela ingqondo kunye namanye amalungu abalulekileyo, kubangele utshintsho lwemithambo-luvo kunye nokuziphatha, ukugula kwesisu, ukukhubazeka kwezintso kunye nokulibaziseka kophuhliso.

Kumanqanaba aphezulu kakhulu, inokubulala.

Ityhefu inokufunyaniswa ngegazi kunye novavanyo lwemifanekiso.

Ukuba i-metal concentrations iphezulu, unyango lunokubandakanya ukusetyenziswa kweziyobisi ze-chelating ezibophelela ukukhokela ukuze zikhutshwe emzimbeni.

Iimpawu ezinetyhefu yelothe

Ngelixa ityhefu inokubangela ukwenzakala phantse kuwo onke amalungu omzimba, ingqondo, kunye nephecana lesisu zihlala apho iimpawu zokuqala zesifo zivela khona.

Iimpawu zetyhefu zihlala zifihlakeleyo kwaye kunzima ukuzibona.

Kwabanye abantu, kunokuba kungabikho zimpawu.

Ezona ziqhelekileyo zibonwa ziquka:

• Ukutshatyalaliswa
• Ukukhathala
• Intloko
• Ukulahlekelwa kukugxila
• Iintsilelo kwinkumbulo yexesha elifutshane
• Isiyezi kunye nokulahleka kolungelelwaniso
• Incasa engaqhelekanga emlonyeni
• Umgca ozuba ecaleni kwetshungama (owaziwa ngokuba ngumgca weBurton)
• Ukuntlitheka okanye ukuziva ndindisholo (neuropathy)
• Intlungu zesisu
• Ukunciphisa ukutya
• Isicaphucaphu kunye ukuhlanza
• Idayarrhea okanye ukutyunjwa
• Intetho edibeneyo

Ngokungafaniyo nabantu abadala, abantwana banokubonisa utshintsho olugqithisileyo lokuziphatha (kubandakanya ukuxhatshazwa, ukunganakwa, kunye nobudlova) kwaye baya kuhlala bekhula emva kwabanye abantwana abaneminyaka efanayo.

Ukukhubazeka kwengqondo okusisigxina ngamanye amaxesha kunokwenzeka.

Iingxaki ezibangelwa yityhefu yelothe zisenokuquka ukonakala kwezintso, uxinezeleko lwegazi, ukungeva kakuhle, ukuba norhatyazo, ukungazali kwamadoda, ukuphunyelwa sisisu nokuzalwa ngaphambi kwexesha.

Ukuba amanqanaba okukhokela anyuka ukuya kuthi ga kwi-100 μg/dL, ukudumba kobuchopho (i-encephalopathy) kunokuthi kwenzeke, kubangele ukuxhuzula, isiqaqa, kunye nokufa.

Izizathu

Abantwana basemngciphekweni omkhulu ngakumbi, ngenxa yobunzima bomzimba wabo omncinci kunye nenqanaba elihambelanayo lokuvezwa.

Bakwathanda ukufunxa ilothe ngokulula ngakumbi kwizicubu zobuchopho kwaye babonise indlela yokuziphatha emlonyeni ekhuthaza ukuvezwa.

Ezinye izizathu eziqhelekileyo zokuvezwa kwelothe ziquka:

• Amanzi, ikakhulu ngenxa yemibhobho yelothe emidala kunye nokusetyenziswa kwesolder yelothe
• Umhlaba oye wangcoliswa yipeyinti enelothe okanye ipetroli
• Ukuvezwa emsebenzini emigodini, kwimizi-mveliso yokunyibilikisa, okanye kwiindawo zokuvelisa apho kubandakanyeka ilothe
• Iingqayi zomdongwe kunye neeseramikhi ezisetyenziselwa isidlo sangokuhlwa
• Ikristale ekhokelayo esetyenziselwa ulwelo oludityanisiweyo okanye ukugcinwa kokutya
• Amayeza e-Ayurvedic kunye namayeza esintu, amanye awo aqulathe ilothe yezibonelelo "zonyango" kwaye ezinye zingcolisiwe ngexesha lokwenziwa.
• Izinto zokudlala, izinto zokuthambisa, iilekese, neemveliso zasendlwini ezivela kumazwe angaphandle ezenziwe kumazwe angenamiqathango yelothe

Ityhefu inokuthi yenzeke ngexesha lokukhulelwa, okubangelwa xa ilahleko yamathambo edlulayo ikhokelela kwinkqubo kwaye ibeka usana olungekazalwa kumazinga aphezulu etyhefu.

Ukuqondwa

Ubutyhefu belothe bunokufunyaniswa ngeentlobo ngeentlobo zelebhu kunye novavanyo lomfanekiso.

Olona vavanyo luphambili, olubizwa ngokuba yi-blood lead level (BLL), lunokusixelela ukuba ingakanani ilothe ekhoyo egazini lakho.

Kwimeko efanelekileyo, akufuneki kubekho ilothe, kodwa kwanamanqanaba aphantsi angathathwa njengamkelekileyo.

Ugxininiso lwelothe yegazi lulinganiswa ngokwemikhrogram (μg) ngedesilitha (dL) yegazi.

Uluhlu lwangoku olwamkelekileyo lu:

• Ngaphantsi kwe-5 μg / dL kubantu abadala
• Akukho nqanaba lamkelekileyo lichongiwe kubantwana

Ngelixa i-BLL inokunika umfanekiso ocacileyo wemeko yakho yangoku, ayinakusixelela isiphumo esongezelekayo esiye sabakho emzimbeni wakho.

Kule nto, ugqirha unokuyalela i-X-ray fluorescence (XRF) engahlaseli (XRF), ngokusisiseko ifom ye-X-ray enamandla kakhulu enokuvavanya ukuba kungakanani na ukukhokela emathanjeni akho kwaye iveze iindawo zokubala ezibonisa ukuvezwa kwexesha elide. .

Olunye uvavanyo lunokubandakanya ukuhlolwa kwefilimu yegazi ukujonga utshintsho kwiiseli ezibomvu zegazi kunye ne-erythrocyte protoporphyrin (EP) enokuthi isinike inkcazo malunga nokuba ixesha elide lokuvezwa liqhubeka.

impatho

Olu hlobo luphambili lonyango lwetyhefu lubizwa ngokuba yi-chelation therapy.

Kubandakanya ukusetyenziswa kwe-chelating agents ezibophelela ngenkuthalo kwisinyithi kwaye zenze i-compound non-toxic enokuthi ikhutshwe ngokukhawuleza kumchamo.

Unyango lwe-Chelation luboniswa kubantu abanobuthi obunzima okanye iimpawu ze-encephalopathy.

Inokuthi ithathelwe ingqalelo kuye nabani na one-BLL engaphezulu kwe-45 μg/dL.

Unyango lwe-Chelation lunexabiso elincinci kwiimeko ezingapheliyo ngaphantsi kweli xabiso.

Unyango lunokusiwa ngomlomo okanye ngemithambo.

Ii-arhente ezimiselweyo zibandakanya:

• I-Bal kwioli (dimercaprol)
• Icalcium disodium
• I-Chemet (i-dimercaptosuccinic acid)
• D-penicillamine
• I-EDTA (i-ethylene diamine tetra-acetic acid)

Iziphumo ebezingalindelekanga zinokubandakanya intloko ebuhlungu, umkhuhlane, ukugodola, isicaphucaphu, ukugabha, urhudo, ukuphefumla nzima, ukubetha kwentliziyo okungaqhelekanga, kunye nokuqina kwesifuba.

Ngezihlandlo ezinqabileyo, ukuxhuzula, ukungaphumeleli kokuphefumla, ukungaphumeleli kwezintso, okanye ukulimala kwesibindi kuye kwaziwa ukuba kwenzeke.
