铝碳酸镁(Magnesium aluminum carbonate)药理作用包括:①中和胃酸:本品可维持胃液pH值在3~5之间,中和99%的胃酸,使80%的胃蛋白酶失活,且抗酸作用迅速、温和、持久。②保护胃黏膜。本品可增加前列腺素E2的合成,增强胃黏膜屏障作用。还可促使胃黏膜内表皮生长因子释放,增加黏液下层疏水层内磷脂的含量,防止H+反渗所引起的胃黏膜损害。③本品可吸附和结合胃蛋白酶,直接抑制其活性,有利于溃疡面的修复,还可结合胆汁酸和吸附溶血磷脂酰胆碱,防止这些物质损伤和破坏胃黏膜。
目前,应用的铸造铝合金有铝硅(Al-Si、铝钢(Al-cu)、铝镁(Al-Mg)及铝锌(Al-Zn)四个组系。按规定,铸造铝合金的牌号用汉语拼音字母“ZL”(铸铝)和三位数字组成.如ZL101、ZL102、ZL201等。
