1. Until recently studies of intestinal aluminium absorption used pharmacological amounts of stable 27Al. 2. To examine the intestinal absorption of trace amounts of different chemical compounds of aluminium, in the present study we have employed the long half-life isotope of aluminium, 26Al, and accelerator mass spectrometry. Trace amounts of 26Al (2.7–12.1 ng) as the hydroxide, citrate, citrate plus 1 mmol/kg sodium citrate, or maltolate respectively, were administered to four groups of rats (n = 9 per group) by gavage. Blood and urine samples were collected for 5 h and the 26Al content (as a percentage of the administered dose) determined by accelerator mass spectrometry. 3. The 5 h urinary 26Al excretion amounted to 0.1 ± 0.02, 0.7 ± 0.2, 5.1 ± 1.5 and 0.1 ± 0.1% of administered dose in the four groups respectively. There was a strong positive correlation between peak plasma 26Al (r = 0.98) and urinary 26Al excretion in individual animals (P < 0.001). 4. We conclude that the fractional intestinal absorption of trace oral doses of aluminium hydroxide is at least 0.1% (compared with the previous estimate of 0.01% using large 27Al oral loads). Absorption of aluminium citrate given alone is significantly greater (0.7%) and is further increased to 5% by the accompanying sodium citrate, consistent with an enhancing effect of added citrate upon mucosal aluminium permeability. Aluminium maltolate absorption approximates that of aluminium hydroxide (0.1%).

Oxalate Ion

SummaryHeparinized blood or plasma coagulates if, after addition of oxalate, recalcification follows. Of the decalcifying agents only oxalate ion has been suitable for demonstrating this phenomenon. Oxalate seem to accomplish two different roles connected with this effect: a fundamental one, i. e., to sensitize a heparinlipoprotein complex to the action of an anti-heparin factor found in normal plasma or serum and a secondary one, related to its capacity to adsorb this antiheparin factor. The latter is removable by centrifugation. This anti-heparin oxalate factor, which is able to counteract the action of heparin after previous addition of oxalate, was found in sequestrened, Dowex 50 resin plasma or in serum, but is not active in citrated plasma. This factor was removed from plasma by adsorption with barium sulfate, aluminium hydroxide or calcium oxalate and was eluted from these adsorbants after incubation with saline.

The title compound, (H3O)2NaAl3F12 [dihydronium sodium trialuminum(III) dodecafluoride], was obtained by solvothermal synthesis from the reaction of aluminium hydroxide, sodium hydroxide, 1,2,4-triazole and aqueous HF in ethanol at 463 K for 48 h. The structure consists of AlF6 octahedra organized in [AlF4 −] n HTB-type sheets (HTB is hexagonal tungsten bronze) separated by H3O+ and Na+ cations.
