Qhov seem nitrogen nyob rau hauv cov ntshav Science News for KIDS

Muaj ntau cov neeg mob xav nyob rau hauv cov nqe lus nug - dab tsi yog qhov biochemistry ntawm cov ntshav, raws li zoo raws li lub residual nitrogen, seev suab ntawm kev kuaj ntshav. Biochemical seev yog lug siv nyob rau hauv lub mob, lawv pab txheeb xyuas mob heev, xws li mob ntshav qab zib, mob cancer hlav, ntau yam anemias, thiab lub sij hawm mus rau noj cov kauj ruam nyob rau hauv cov kev kho mob. residual nitrogen tam sim no nyob rau hauv lub urea, creatinine, amino acids, indikane. Nws theem yuav tau qhia tej pathological kev hloov nyob rau hauv tib neeg lub cev.

Biochemical tsom xam ntawm cov ntshav

Ua qauv qhia tsom xam ntawm lub biochemical muaj pes tsawg leeg ntawm cov ntshav tso cai ib tug high degree ntawm qhov muaj tseeb los mus taw qhia thaum ntxov ua sawv ntawm ntau yam kev hloov nyob rau hauv ntaub so ntswg thiab kabmob. Kev npaj rau biochemistry ua nyob rau hauv tib txoj kev raws li thaum noj kev kuaj ntshav. Yuav kom kawm cov ntshav tau coj los ntawm cov cubital cov hlab ntsha. Tseem ceeb kev yog:

• muaj cov protein;
• nitrogenous feem - so nitrogen, creatinine, urea, inorganic tebchaw;
• bilirubin;
• Cov theem ntawm roj metabolism.

Lub residual ntshav nitrogen - yog dab tsi?

Nyob rau hauv nqa tawm cov ntshav ntsuam biochemical tsis soj ntsuam nyob rau hauv tag nrho cov ntshav cov ntsiab lus ntawm cov tshuaj uas muaj xws li nitrogen, tsuas yog tom qab tag nrho cov nqaijrog twb muab rho tawm. Tus nqi ntawm cov ntaub ntawv no yog hu ua residual ntshav nitrogen. Kaw, qhov no daim duab tsuas yog tom qab lub deleted cov nqaijrog, rau qhov yog vim li cas hais tias lawv muaj nyob rau hauv tib neeg lub cev muaj feem ntau nitrogen. Yog li txiav txim siab bun, amino acids, creatinine, indican, uric acid, ammonia. Nws tej zaum yuav muaj nitrogen thiab lwm yam uas tsis yog-protein tshuaj ntawm keeb kwm: peptides, bilirubin thiab lwm yam sib txuas. Cov ntaub ntawv tsom xam rau residual nitrogen muab ib lub tswv yim ntawm cov kev kho mob ntawm tus neeg mob, qhia mob kab mob feem ntau yog txuam nrog cov teeb meem ntawm deducing thiab filtering zog ntawm ob lub raum. Feem ntau, cov residual nitrogen - los ntawm 14.3 mus 28.5 mmol / liter. Kom uas tshwm sim nyob rau hauv ib tug tom qab:

• polycystic;
• mob raum kab mob;
• hydronephrosis;
• pob zeb nyob rau hauv lub ureter;
• tuberculous raum puas tsuaj.

diagnostics

Txij li thaum lub residual qauv mus rau nitrogen nkag mus rau hauv biochemical tsom xam, cov kev npaj yog nqa tawm raws li cov ntsiab cai raws li ua ntej tus me nyuam mus rau lwm cov Cheebtsam ntawm tus mob. Yog xav paub ntxiv muaj tseeb tau yog tsim nyog los soj ntsuam ib tug xov tooj ntawm cov kev cai thaum lub sij hawm ntawm cov ntshav biochemistry:

•, thiab hais tias rau cov thawj lub sij hawm Yog hais tias koj yuav tsum coj lub re-tsom xam, nws yog zoo dua rau ua nws nyob rau hauv tib lub laboratory. Txij li thaum tag nrho lawv diagnostic kuaj ntsuam xyuas, lawv yog cov sib txawv tshuab rau kev ntsuam xyuas tau.
• Ib tug ntshav yog coj los ntawm cov cubital cov hlab ntsha, tej zaum vim hais tias ntawm ib tug ntiv tes, yog hais tias muaj yog tsis muaj kev nkag tau mus rau lub cov hlab ntsha los yog puas ntsoog.
• qhia saib kev tsom xam yuav tsum yog nyob rau hauv ib qho kev npliag plab, tsis tsawg tshaj 9-12 teev tom qab kawg noj mov. Koj muaj peev xwm haus dej haus dej, tab sis tsis muaj roj.
• Qhov zoo tshaj plaws lub sij hawm rau cov ntshav sau los yog xav tau 7-10 am.
• Peb hnub ua ntej tus tsom xam yog ib qho zoo kom noj zaub mov zoo, koj yuav tsum tau tsuas tshem tawm fatty, ntsim thiab kib.
• Nyob rau lub peb hnub, mus kaws ntaus pob ncaws pob ua ub no, tshwj xeeb tshaj yog yog hais tias lawv yog txuam nrog rau congestion ntawm lub cev.
• Yog hais tias koj yuav tsum tau mus soj ntsuam rau residual ntshav nitrogen, biochemistry yuav tsum tau qhov kev tshem tawm ntawm cov tshuaj. Nyob rau qhov no, tus kws kho mob yuav tsum tau yuav tsum tau los sib tham.
• Nyob rau qhov kev tshwm sim tej zaum yuav cuam tshuam rau kev nyuaj siab, ntxhov siab vim, li ntawd, tsawg kawg yog ib nrab ib teev ua ntej qhov kev kuaj yuav tsum zaum nyob rau hauv ib tug xoob cua.
Yog hais tias cov kev npaj rau Biochemistry dhau thwj, cov kev kuaj tau yuav ntau yog. Txiav suab ntawm cov yuav tsum tau tsuas nrog kws kho mob. Indicators feem ntau ywj faj ywj fwm tus txheeb ze rau tus txheej txheem, vim li ntawd lawv yuav tsum tau ntawm nws tus kheej txhais incorrectly.

Tej residual nitrogen nyob rau hauv cov ntshav

Tej readings residual ntshav nitrogen haum nyob rau hauv cov nuj nqis ntawm 14.3 mus 26.8 mmol / l. Nws yuav tsum tau muab sau tseg tias sawv ntawm qhov ntsuas txawm mus rau 30-36 mmol / l yog tsis kho tam sim ntawd raws li ib tug manifestation ntawm pathology. Qhov seem nitrogen yog ntau tshaj tus nqi yuav sawv nyob rau hauv txoj kev siv cov nitrogen-muaj khoom noj khoom haus, cov zaub mov txias thaum lub sij hawm noj, nrog ib tug tshaj ntawm ntxiv tshuaj. Dhia nyob rau hauv thiab tej zaum yuav tshwm sim ua ntej yug tus me nyuam, tom qab amplification kev ua si txoj kev kawm thiab rau lwm cov yog vim li cas. Uas yog vim li cas rau qhov tus me nyuam kev kuaj ntshav Science News for KIDS yuav tsum tau ua tib zoo npaj. Yog hais tias tus tsom xam dramatically overstate los yog understate tus nqi thiab yog li muaj txoj cai npaj ua ntej yuav ntshav zauv, qhov no tej zaum yuav qhia ib tug xov tooj ntawm cov kab mob nyob rau hauv lub cev.

Nyob rau hauv ib tug nitrogen residual feem xws li:

• urea nitrogen (ntawm 46-60%);
• creatine (2.5-2.7%);
• amino nitrogen (25%);
• uric acid (4%);
• creatinine (2,6-7,5%);
• lwm yam khoom uas muaj protein ntau metabolism.

Qhov seem nitrogen - yog qhov txawv ntawm qhov residual nitrogen thiab urea nitrogen. Ntawm no, cov dawb feem yog free amino acids.

pathologies

Rau cov residual nitrogen pathologies muaj xws li:

• hyperasotemia - thaum cov theem ntawm residual nitrogen nyob rau hauv cov ntshav yog siab dhau heev lawm;
• gipoazotemiya - residual nitrogen nyob rau hauv cov ntshav tsawg.

Gipoazotemiya ntau cai nyob rau hauv uas tsis muaj hwj chim los sis nyob rau hauv uas tsis tshua muaj mob, thaum lub sij hawm cev xeeb tub.

Hyperasotemia muab faib mus rau hauv ib tug ntau lawm thiab cia.

Thaum tus tuav hyperasotemia ua txhaum tshwm sim raum excretory muaj nuj nqi, nyob rau hauv cov ntaub ntawv no thiaj paub hais tias lub raum tsis ua hauj lwm. Lub ntsiab yog vim li cas ntawm tus tuav hyperasotemia yog cov nram qab no cov kab mob:

• glomerulonephritis;
• pyelonephritis;
• hydronephrosis los yog lub raum tus kab mob ntsws;
• polycystic;
• nephropathy thaum lub sij hawm cev xeeb tub;
• tawg nyob rau hauv txoj kev loj hlob ntawm lub raum kab mob;
• muaj kev lom los yog txhua yam teeb meem mus rau lub outflow ntawm cov zis (pob zeb, xuab zeb, malignant los yog benign growths nyob rau hauv lub ob lub raum, mob txeeb zig).

Lub ntau lawm hyperasotemia

Tus muaj zog residual ntshav nitrogen tej zaum yuav qhia ib tug ntau lawm hyperasotemia thaum nrog pathological mob syndrome endogenous intoxication. Nws yog kuj cai nrog heev kev nyuaj siab nyob rau hauv lub postoperative lub sij hawm. Sau ntawv produktsionnaja hyperasotemia nyob rau hauv kis kab mob uas tshwm sim nrog kub taub hau, thaum muaj ib tug hnyav disintegration ntawm cov ntaub so ntswg, qhov no muaj xws li cov kab mob: diphtheria, typhus, kub taub hau, lobar mob ntsws dej. Lub ntau lawm hyperasotemia yus los ntawm kev ua residual nitrogen qhia los ntawm thawj hnub ntawm tus kab mob thiab kom txog thaum tsis ntev los no ces tsa kub.

Tus txheeb ze yuav tshwm sim thaum tawm hws, ntshav txhaws, thiab profuse raws plab, thaum tawg nyob rau hauv lub cev dej tshuav nyiaj li cas.

mixed hyperasotemia

Muaj qee zaus thaum nce residual nitrogen thiab mixed hyperasotemia txiav txim. Nws feem ntau tshwm sim thaum tshuaj lom los ntawm tej yam tshuaj lom: dichloroethane, mercury ntsev, lwm yam sib txuas. Cov ua tej zaum yuav raug mob txuam nrog heev compression ntawm ntaub so ntswg. Nyob rau hauv xws li mob, lub immobilization yuav tshwm sim raum ntaub so ntswg, nyob rau cia hyperasotemia pib nrog productional. Thaum lub siab tshaj plaws nyob ntev hyperasotemia residual nitrogen nyob rau hauv tej rooj plaub tshaj tus nqi ntawm nees nkaum lub sij hawm. Sau npe xws ntsuas nyob rau hauv huab mob, lub raum kev koom tes.

residual nitrogen ntsuas yog inflated tsis tau tsuas yog nrog raum kab mob. Addison tus kab mob (lus adrenal muaj nuj nqi) raws li cov kev cai yog zoo tshaj. Qhov no tshwm sim thiab thaum twg lub plawv tsis ua hauj lwm, burns high degree ntawm lub ntiajteb txawj nqus, nrog lub cev qhuav dej, nyob rau hauv kev mob loj kab mob kab mob, mob kev nyuaj siab thiab pais plab los ntshav.

kho

Tshem tawm cov tsos mob overestimated residual nitrogen yuav muaj sij hawm mus nrhiav qhov ua rau ntawm tus mob no. Rau ntxiv kev kho mob cov kws kho mob yuav tsum tau xaiv ib tug xov tooj ntawm ntxiv cov kev tshawb fawb, cov kev tshwm sim ntawm uas nws tau xaus lus kom txhim tsa lub tseeb mob thiab muab cov kev tsim nyog noj tshuaj los yog lwm yam kev kho mob. Nyob rau hauv lub sij hawm los xyuas txog cov kab mob thiab kho nws, koj yuav tsum raws sij hawm dhau soj ntsuam thiab xeem dhau tag nrho cov kev ntsuam xyuas. Yog hais tias pom tej pathology, yog kev kho mob yuav tsis tsim teeb meem, mus rau lub aggravation ntawm tus kab mob thiab tus mob daim ntawv.
