Abstract
OBJECTIVE
Kidney stones are a common complication of hyperoxaluria. The aim of this study is to investigate the protective and preventive effects of Ulva lactuca aqueous extract, ulvan polysaccharides and atorvastatin on ethylene glycol-induced hyperoxaluria.
MATERIALS AND METHODS
Male Wistar rats between 110 and 145 g in weight were used in the study, Ulva lactuca aqueous extract and polysaccharides were prepared. The male albino rats were supplemented with 0.75 percent ethylene glycol (v/v) in their drinking water for six weeks to induce hyperoxaluria. Ulvan infusions (100 mg/kg body weight), ulvan polysaccharides (100 mg/kg body weight), and atorvastatin (two milligrams/kg body weight) to treat hyperoxaluric rats for four weeks (every other day) were used. Weight loss, serum creatinine, serum urea, serum uric acid, serum oxalate, kidney oxalate, kidney lipid peroxidation, and kidney DNA fragmentation and kidney histopathological studies were done.
RESULTS
Weight loss, rise of serum creatinine, serum urea, serum uric acid, serum oxalate, kidney oxalate, kidney lipid peroxidation, and kidney DNA fragmentation were all shown to be prevented by the addition of atorvastatin, polysaccharides, or aqueous extract, respectively. Catalase (CAT) activity, glutathione peroxidase (GPX) activity, glutathione-S-transferase (GST) activity, and histopathological perturbations were all significantly reduced by the medicines that were studied.
CONCLUSIONS
Hyperoxaluria caused by ethylene glycol may be prevented by a combination of Ulva lactuca aqueous extract, ulvan polysaccharides, and atorvastatin. A reduction in renal oxidative stress and an improvement of the antioxidant defense system may be responsible for these protective benefits. However, Ulva lactuca infusion and ulvan polysaccharides need to be studied further in humans, in order to determine their efficacy and safety.
