Aluminum chloride was administered subcutaneous to domestic rabbits alone or in association with citrate (as citric acid) or fluoride (as NaF). This paper presents the modifications of carbohydrate, proteins and albumins in respect with control group C, for three experimental groups, E1, E2, E3, in rabbit’s blood serum. The blood serum glucose level varied between 119.6±7.1 mg/dL in-group C and 98.7±24.0 mg/dL in E1, 108.6±7.4 mg/dL in E2 and 101.7±4.6 mg/dL in E3 group. The variation of proteins and albumins was not in very large limits for E1 group comparing with control, but at the same dose of AlCl3 administered, the presence of citrate in E2 group and fluoride in E3 group can decrease blood concentration of those. Modifications of blood parameters presented here could be explained in relations with the oxidative stress induced by aluminum.
