L-valine khoom siv
【Siv 1】 Nws yog ib qho tseem ceeb amino acid rau tib neeg lub cev.Nws yog siv los ua ib yam ntawm cov amino acid infusion hauv tshuaj.Nws kuj tseem siv tau los ua khoom noj khoom haus ntxiv los ua cov tshuaj tshiab.
【Siv 2】 Cov khoom noj khoom haus.Nws tuaj yeem ua ke nrog lwm cov amino acids tseem ceeb los tsim cov amino acid infusion thiab kev npaj cov amino acid.
Valine (1g, / kg) yog ntxiv rau cov ncuav mog qab zib, thiab cov khoom muaj suab thaj tsw qab.Nws tuaj yeem txhim kho qhov tsw thaum siv hauv khob cij.
【Siv 3】 Amino acid tshuaj.Khoom noj khoom haus ntxiv, tuaj yeem siv los ua cov khoom tseem ceeb ntawm cov amino acid infusion thiab kev npaj cov amino acid.L-valine yog ib qho ntawm peb ceg ntawm cov amino acids thiab yog ib qho tseem ceeb amino acid, uas tuaj yeem kho lub siab tsis ua haujlwm thiab lub hauv nruab nrab lub paj hlwb tsis ua haujlwm.
【Siv 4】 Nws yog siv rau kev tshawb fawb biochemical, kev npaj cov ntaub so ntswg kab lis kev cai nruab nrab, thiab raws li amino acid khoom noj khoom haus tshuaj nyob rau hauv cov tshuaj.
【Siv 5】 Nws yog ib qho tseem ceeb amino acid.Cov txiv neej laus xav tau 10mg/(kg·d).Cov nyhuv physiological ntawm L-hom yog ob zaug ntawm D-hom.Xws li qhov tsis muaj peev xwm ua rau muaj kev puas siab puas ntsws, nres kev loj hlob, poob phaus, anemia thiab lwm yam.Raws li kev noj haus ntxiv, nws tuaj yeem ua ke nrog lwm cov amino acids tseem ceeb los tsim cov amino acid infusion thiab kev npaj cov amino acid.Valine (1g / kg) yog ntxiv rau cov ncuav mog qab zib, thiab cov khoom muaj cov tshuaj tsw qab, uas tuaj yeem txhim kho qhov tsw thaum siv hauv khob cij.
【Siv 6】 Kev npaj cov ntaub so ntswg kab lis kev cai nruab nrab.
Kev siv thaj chaw ntawm L-valine
