Blood and brain aluminium concentrations in mice after intra-pertioneal injection of different aluminium compounds.

Aluminium chloride, nitrate, lactate and gluconate was injected by intraperitoneal route to mice at equimolecular doses, equivalent to 54 and 5.4 mg/kg of metal. The blood aluminium concentrations were increased to very high values with gluconate (99.5 mg/l) to high values with lactate (4.5 mg/l) and to low values with nitrate and chloride (0.3 mg/l). Brain aluminium concentration was increased only with glutconate at the dose of 54 mg/kg. The quantity of aluminium found in blood and brain after intraperitoneal administration at equimolecular doses is very dependent of the preparation of aluminium used.
