The enteral bioavailability of magnesium firmly bound to a fire-proof, inert SiO2-Al2O3 matrix (ground magnesia boats) was studied in magnesium-deficient albino Sprague-Dawley rats, with and without blocking gastric hydrochloric acid secretion with omeprazole. Magnesium was absorbed, although to a small degree, also at anacidity. Pronounced erythema, developing after only some days in hypomagnesemic hypercalcemic rats, are proposed as a non-invasive model for the screening of antiinflammatory substances. Using this model significant protective effects were proven for cromoglycate, polyenthylene glycol 400, and omeprazole; the latter, however, seems more likely to act via a magnesium-sparing mechanism.
在缺镁的白化斯普拉格-道利大鼠中,研究了牢固结合在防火惰性二氧化硅 - 氧化铝基质(研磨氧化镁舟皿)上的镁的肠内生物利用度,实验分使用奥美拉唑阻断胃盐酸分泌和未阻断胃盐酸分泌两组。即使在胃酸缺乏的情况下,镁也有少量吸收。低镁血症高钙血症大鼠仅在数天后出现的明显红斑,被提议作为筛选抗炎物质的非侵入性模型。使用该模型,已证实色甘酸盐、聚乙二醇400和奥美拉唑具有显著的保护作用;然而,后者似乎更可能通过保镁机制发挥作用。
