These effects are mediated bynactivation of peroxisome proliferator-activated receptor-α, which decreases the secretion of VLDL and increases its peripheral metabolism(C)見下圖(D)reductase inhibitors clearly induce an increase in high-affinity LDL receptors. 【國考複習】統整表格詳見(pharmabook (王瑞賢) 藥理藥化統整本 3.0 P.1... 查看完整內容 |
