Hauv cov neeg mob ntshav siab, ntau cov vitamin B1 poob rau hauv cov zis vim tias cov tshuaj diuretics feem ntau siv rau cov neeg mob ntshav siab. Tsis tas li ntawd, digoxin kuj tseem tuaj yeem txo lub peev xwm ntawm cov leeg hlwb kom nqus tau thiab siv cov vitamin B1.
Kev ceev faj rau kev siv cov vitamin B1
1. Thaum siv cov koob tshuaj loj, kev txiav txim siab ntawm cov ntshav theophylline concentration tuaj yeem cuam tshuam, kev txiav txim siab ntawm uric acid concentration tuaj yeem ua rau muaj kev dag ntxias, thiab urobilinogen tuaj yeem ua rau tsis zoo.
2. Vitamin B1 yuav tsum tau siv ua ntej txhaj tshuaj rau kev kho mob ntawm Wernicke's encephalopathy.
3. Vitamin B1 feem ntau tuaj yeem noj tau los ntawm cov zaub mov ib txwm muaj, thiab qhov tsis txaus ntawm monovitamin B1 yog tsawg. Yog tias cov tsos mob tsis txaus, qhov zoo dua ntawm B-complex vitamin.
4. Yuav tsum tau noj raws li kev pom zoo, tsis txhob noj ntau dhau.
