Birkner E, Grucka-Mamczar E, Zwirska-Korczala K, Zalejska-Fiolka J, Stawiarska-Pieta B, Kasperczyk S, Kasperczyk A: Influence of sodium fluoride and caffeine on the kidney function and free-radical processes in that organ in adult rats. Biol Trace Elem Res. 2006 Jan;109(1):35-48.
An experiment was carried out on Sprague-Dawley rats (adult males) that for 50 days were administered, in the drinking water, NaF and NaF with caffeine (doses, respectively: 4.9 mg of NaF/kg body mass/24 h and 3 mg of caffeine/kg body mass/24 h). Disturbances were noted in the functioning of kidneys, which were particularly noticeable after the administration of NaF with caffeine. Changes in the functioning of kidneys were also confirmed by such parameters as the level of creatinine, urea, protein, and calcium. Modifications of the enzymatic antioxidative system (superoxide dismutase, catalase, and glutathione peroxidase) and lipid peroxidation (malondialdehyde) were also observed. Changes in the contents of the above parameters as well as pathomorphological examinations suggest increased diuresis, resulting in dehydration of the rats examined. |
