Pharmacological teebmeem ntawm Astragalus
1. Kev tiv thaiv kab mob plawv
Cov nyhuv Cardiotonic: Hauv kev sim hauv vitro, tag nrho saponins ntawm Astragalus tuaj yeem ua rau muaj kev ua haujlwm ntawm superoxide dismutase (SOD) thiab tiv thaiv myocardium. Astragalus preconditioning tuaj yeem txo cov kev raug mob ischemia-reperfusion hauv cardiomyocytes thiab endothelial hlwb, tejzaum nws los ntawm stabilizing cov qauv thiab kev ua haujlwm ntawm cardiomyocyte membranes thiab mitochondria.
Tswj cov ntshav siab thiab tiv thaiv cov hlab ntsha: Astragalus muaj ob txoj hauv kev tswj cov ntshav siab. Astragalus tuaj yeem diuretic ntshav siab, txo cov hlab ntshav siab thiab txoj cai ventricular preload, nthuav cov hlab ntsha peripheral, txhim kho microcirculation, txo cov hlab ntsha siab, thiab ncaj qha nthuav cov hlab ntsha.
2. Immunomodulatory teebmeem
Hauv kev sim tsiaj, astragalus tuaj yeem txhim kho T cell muaj nuj nqi, txhim khu kev tshem tawm ntawm cov kab mob hauv lub cev, thiab ua kom cov tshuaj tiv thaiv kab mob ntau ntxiv. Nws txhawb kev loj hlob ntawm cov plasma hlwb, feem ntau yog cov plasma cov hlwb paub tab, thiab ua rau cov tshuaj tiv thaiv kab mob ntau ntxiv.
3. Anti-diabetic nyhuv
Astragalus yog cov tshuaj suav tshuaj feem ntau siv rau kev kho mob ntshav qab zib.
Astragalus tuaj yeem txhim kho cov teeb meem ntshav qab zib. Nws tuaj yeem txhim kho qhov ntxov hyperperfusion thiab hyperfiltration xeev ntawm ntshav qab zib nephropathy los ntawm inhibiting cov synthesis ntawm lub raum NO, thiab tseem tuaj yeem nce qib ntawm plasma albumin, tswj lipid metabolism, thiab txhawb kev tso tawm ntawm dej thiab sodium. Astragalus txhawb cov ntshav ncig thiab tshem tawm cov ntshav stasis, tiv thaiv lub raum ua haujlwm.
