Abstract
OBJECTIVE: Urinary stones with oxalate composition can cause kidney failure. Recent findings evidenced that probiotics are effective in reducing oxalate absorption in these subjects based on their high colonic absorption levels at baseline. The purpose of this study was to evaluate the effect of the simultaneous use of oxalate-degrading bacteria, Urtica dioica and T. terrestris extract in reducing urinary oxalate. MATERIALS AND METHODS: Anti-urolithiatic activity of Urtica dioica and T. terrestris extract and pro-biotic by using ethylene glycol induced rat model. In this study, 4 strains of Lactobacillus and 2 strains of Bifidobacterium and also 2 strains of L. paracasei (that showed high power in oxalate degrading in culture media) were used. Male Wistar rats were divided into four groups (n=6). The rats of group-I received normal diet (positive control group) and groups-II (negative control group), III, IV rats received diet containing ethylene glycol (3%) for 30 days. Groups III rats re-ceived Urtica dioica and T. terrestris extract. Groups IV rats received extracts + probiotic for 30 days. FINDINGS: The results show that the use of herbal extracts (Urtica dioica and T. terrestris) redu-ced the level of urinary oxalate and other parameters of urine and serum. Also, the accumulation of calcium oxalate crystals in the kidney tissue was significantly reduced. CONCLUSION: Considering that the formation of calcium oxalate crystals can cause inflammation and tissue damage in the kidney, the use of herbal extracts with oxalatedegrading bacteria can be a new therapeutic approach to preventing the formation of kidney stones.
