Zoo Siab

Cov tshuaj lom Lawv yog cov khoom siv tshuaj lom neeg uas nyob hauv qee yam ntawm lawv cov txheej txheem (tsim khoom, siv, faib khoom lossis pov tseg) ua rau muaj kev pheej hmoo rau tib neeg kev noj qab haus huv (kab mob lossis tuag taus).

Txawm hais tias muaj tshuaj lom tshwm sim thaum ib qib twg muaj teeb meem rau kev noj qab haus huv, nws feem ntau cuam tshuam nrog noj: Cov tshuaj lom feem ntau yog cov tshuaj siv hluavtaws, uas ua rau puas tsuaj thaum siv qhov ncauj.

Kev faib tawm

Cov toxicology yog qhov tshwj xeeb mob siab rau hom tshuaj no. Qhov cuam tshuam ntawm cov tshuaj lossis cov xwm txheej sab nraud ntawm cov neeg muaj sia, cov kab mob lom neeg, lub cev, cov nqaij thiab cov cell, yog thaj tsam ntawm kev kawm txog kev qhuab qhia no.

Feem ntau nws txawv qhov chaw muaj tshuaj lom ua peb pawg:

  • Tshuaj lom neeg cov organic thiab inorganic uas ua rau lub cev puas tsuaj: cov tshuaj lom neeg xws li cov hmoov txhuas tshwm ntawm cov tsis muaj tshuaj lom, thaum cov organic muaj cov tshuaj xws li methanol, thiab ntau yam tshuaj lom ntawm tsiaj keeb kwm.
  • Kev lom lom lom, Nws yog tsim nrog cov co toxins uas tau tsim los ntawm cov kab mob thiab cov kab mob, uas tsim tawm los ntawm kev tsim cov kab mob. Tsis zoo li yav dhau los, hom tshuaj lom no nyob ntawm tus tswv lub peev xwm los tiv thaiv nws tus kheej, vim nws muaj peev xwm tias ob yam tshuaj zoo ib yam ua txawv ntawm cov neeg txais khoom sib txawv.
  • Lub cev muaj tshuaj lomNws yog qhov sib txawv uas feem ntau tsis yog tshuaj lom, tab sis qhov ntawd tseem cuam tshuam rau lub cev xws li X-rays thiab gamma rays, lossis hluav taws xob los ntawm ntau qhov sib txawv.

Hom kev puas tsuaj uas lawv tsim

Thaum co toxins nkag rau hauv lub cev, lawv tuaj yeem tsim ntau hom kev hloov kho lossis raug mob (los ntawm cov cell uas tsis zoo) lossis ua haujlwm zoo (xws li hloov pauv DNA lossis txwv tsis pub ua enzymatic). Cov txiaj ntsig lawv muaj hauv lub cev faib cov tshuaj lom rau hauv kev faib tawm tshiab:

  1. Ua xua tshuaj lom: Cov tshuaj lom nkag mus rau hauv cov qauv ntawm cov protein.
  2. Tshuaj loog tshuaj lom: Lawv cuam tshuam rau lub hauv paus paj hlwb.
  3. Choking co toxins: Lawv txwv tsis pub cov pa oxygen nkag mus rau cov nqaij.
  4. Carcinogenic co toxins: Lawv cuam tshuam cov qauv ntawm RNA thiab DNA.
  5. Corrosive tshuaj lom: Lawv rhuav tshem cov ntaub so ntswg uas lawv ua.

Kev tshwm sim hauv lub cev

Thaum tib neeg lub cev dhau los ntawm cov ntsiab lus uas muaj teeb meem rau nws txoj kev noj qab haus huv, nws tau hais tias lub cev yog qaug cawv. Hauv cov xwm txheej no, lub cev feem ntau tawm tsam cov tshuaj, tswj kom tswj nws, txo nws lub sijhawm luv thiab tshem tawm nws: txawm li cas los xij, qee zaum cov txheej txheem no ua tsis tau vim tias kev tiv thaiv ntuj qis, lossis vim tias muaj qhov siab ntawm cov tshuaj nkag mus .


Cov tsos ntawm pob ntxau thiab khaus khaus, ua npaws hnyav, ua pa nyuaj, raws plab hnyav, ntuav hnyav, thiab lwm yam tsos mob Lawv yog cov uas lub cev siv los ua rau qaug cawv, thiab lawv yuav tsum tau kho los ntawm kws kho mob raws li qhov tsim nyog.
