Comparing the effects of salts of diclofenac and alminoprofen with aspirin on serum electrolytes, creatinine and urea levels in rabbits.

The effects of diclofenac sodium, diclofenac potassium, alminoprofen and aspirin on serum electrolytes (serum Na(+) and K(+)), urea and creatinine were compared in rabbits in acute and chronic phases of treatment. The data suggested that all the four drugs markedly increased the serum electrolytes, urea and creatinine levels in both post-treatment phases. In conclusion, present study does not present any advantage of diclofenac sodium over diclofenac potassium at electrolyte levels on short and long term treatment. Nevertheless, current data support the evidence of renal function impairment by all the four drug therapies used in the present study, which is generally caused by NSAIDS.

A comparative study of antioxidant vitamins and simvastatin in hypercholesterolimic rabbits.

The anti-lipidemic effects of orally administered antioxidant vitamins (vitamin A, vitamin C and vitamin E) individually and in combination were studied in cholesterol-fed rabbits and compared to the group of hypercholesterolemic animals that were treated with simvastatin. All treatment groups exhibited a decrease in serum total cholesterol, low density lipoprotein-cholesterol (LDL-C) and triglycerides concentrations, whilst vitamin C, vitamin E, the combination and simvastatin showed a more profound decrease in the lipid profile than vitamin A at different time intervals. The order of increase in high density lipoprotein-cholesterol (HDL-C) levels remained in favour of simvastatin, as none of the antioxidant vitamins treated group could exhibit a profound increase in the HDL-C.
