Calcitriol ua rau cov hlwb hauv plab hnyuv nce tsim tawm ntawm calcium thauj cov protein, hu ua calbindin-D cov protein, uas ua rau nce uptake ntawm calcium los ntawm lub cev mus rau lub cev. Nov yog tib lub tswv yim uas lub cev ua tau nce nws calcium khw.
Yog li ntawd, calcitriol puas nce ntshav calcium?
Calcitriol nce cov ntshav calcium (CaJ2+) feem ntau yog los ntawm nce ntxiv kev uptake calcium los ntawm cov hnyuv.
Ib sab saum toj no, dab tsi pab txhawb kev nqus calcium? Vitamin D yog cov khoom tseem ceeb tshaj plaws rau kev tsim nyog nqus ntawm calcium . Ntxiv rau cov vitamin D, vitamin C, vitamin E, vitamin K, magnesium, thiab boron pab nqus calcium thiab kuj nce pob txha loj. Qoj ib ce thiab pab lub cev nqus tau calcium.
Ib yam li ib tus yuav nug, yuav ua li cas cov vitamin D nce calcium nqus?
Vitamin D txhawb nqa calcium nqus hauv lub plab thiab tswj cov ntshav kom txaus calcium thiab phosphate concentrations los pab kom ib txwm mineralization ntawm pob txha thiab tiv thaiv hypocalcemic tetany. Nws kuj tseem xav tau rau pob txha loj hlob thiab kho pob txha los ntawm osteoblasts thiab osteoclasts [1, 2].
Puas yog calcitriol ua rau pob txha resorption?
Calcitriol . Calcitriol muaj nyob rau hauv cov ntsiav tshuaj los yog ib qho tshuaj txhaj (IV) formulation. Qhov ncauj calcitriol ua tau zoo txo qib PTH, txo qis pob txha resorption , txhim kho endosteal fibrosis thiab mineralization, thiab rau qee qhov kev pab hauv pob txha mob txuam nrog lub raum osteodystrophy.
