Tsis tas li ntawd, kev tshem tawm tshuaj raug xam li cas?
Feem ntau, tshem tawm ntsuas hauv L / h lossis mL / min. Qhov ntau xav txog tus nqi ntawm tshuaj tshem tawm faib los ntawm plasma concentration. Yog li, tag nrho lub cev tshem tawm yog sib npaug ntawm cov zauv tshem tawm ntawm cov khoom los ntawm txhua lub cev (piv txwv li, lub raum tshem tawm + cev tshem tawm + lub ntsws tshem tawm = tag nrho lub cev tshem tawm ).
Tsis tas li ntawd, qhov sib txawv ntawm kev tshem tawm thiab tus nqi ntawm kev tshem tawm yeeb tshuaj yog dab tsi? Clearance txhais tau tias yog 'lub ntim ntawm cov ntshav tshem tawm tshuaj rau ib lub sijhawm twg '. Tshuaj tshem tawm tus nqi txhais tau tias yog 'tus nqi ntawm tshuaj tshem tawm ntawm cov ntshav ib lub sijhawm twg 'Hauv thawj qhov kev txiav txim siab kinetics, tshem tawm tus nqi yog proportional rau koob, thaum tshem tawm tus nqi tseem nyob ywj pheej ntawm koob tshuaj.
Ua raws li qhov no, vim li cas kev tshem tawm tshuaj tseem ceeb?
Clearance , parameter uas cuam tshuam tus nqi ntawm tshem tawm rau tshuaj concentration, yog tseem ceeb vim hais tias nws txhais tau hais tias tus nqi ntawm kev tswj hwm yuav tsum tau tuav lub toj siab tshuaj siab. Qhov rhiab heev ntawm lub cev tshem tawm ntawm a tshuaj rau kev hloov pauv hauv kev khi hauv ntshav nyob ntawm nws qhov tsis txwv tshem tawm.
Kev tshem tawm yeeb tshuaj yog dab tsi?
Tshuaj tshem tawm yog tshem tawm ntawm tshuaj los ntawm lub cev. Tej zaum lawv yog tshem tawm tom qab raug hloov kho (metabolized), los yog lawv yuav ua tau tshem tawm zoo li qub. Feem ntau tshuaj , tshwj xeeb yog dej-soluble tshuaj thiab lawv cov metabolites, yog tshem tawm feem ntau los ntawm ob lub raum hauv cov zis.

Yog tias koj pom qhov tsaus ntuj nti lossis lub teeb ci, nws muaj peev xwm koj tuaj yeem muaj cov kab mob tom qab vitreous detachment (PVD), qhov muag teeb meem ntau tus neeg muaj thaum lawv hnub nyoog. Raws li koj tau txais ntau dua, cov gel hauv koj lub qhov muag -hu ua vitreous gel -tuaj yeem ntsws. Teeb meem pom kev tshwm sim los ntawm PVD feem ntau tau zoo dua ob peb lub lis piam
Kev laus cuam tshuam li cas cov tshuaj nqus cov metabolism hauv kev faib tawm thiab kev tso tawm?
Raws li hnub nyoog nce, kev ua haujlwm ntawm cov nqaij thiab cov kabmob hauv lub cev maj mam poob qis. Vim qhov kev poob qis hauv kev ua haujlwm hauv lub cev, kev nqus tshuaj, kev faib tawm, cov metabolism hauv thiab kev tso tawm (cov txheej txheem ADME) hauv cov neeg laus muaj qhov phem dua li cov tub ntxhais hluas
Dab tsi yog ob qho teeb meem kev kho tshuaj feem ntau pom hauv cov neeg mob tau txais kev pabcuam kev tswj hwm tshuaj?
Ob qhov teeb meem kev kho tshuaj feem ntau pom nyob rau hauv cov neeg mob uas tau txais kev pab tswj xyuas cov tshuaj muaj txhij txhua yog: (1) Tus neeg mob yuav tsum tau kho tshuaj ntxiv rau kev tiv thaiv, kev sib koom ua ke, lossis kev kho mob palliative; thiab (2) Cov koob tshuaj yuav tsum tau muab teev cia kom ua tiav qib kev kho mob uas mus txog
Thawj qhov kev txiav txim ntawm Oprelvekin neumega uas yog tshuaj nyob rau hauv kev faib tawm interleukin IL yog dab tsi?
Tshem tawm ib nrab-lub neej: 6.9 ± 1.7h
Dab tsi yog kev xav ntawm kev xav ntawm kev tshuaj yeeb tshuaj?
Kev ua siab ntev ntxiv uas txhais tau tias tus neeg siv yuav tsum tau noj ntau dua ntawm cov tshuaj kom tau txais cov txiaj ntsig xav tau. Txhais kev puas siab puas ntsws dependence. Tshwm sim thaum cov tshuaj dhau los ua ib feem tseem ceeb ntawm tus neeg txoj kev xav, kev xav thiab kev ua ub no, ua rau muaj kev mob siab rau siv tshuaj
