Reducing urinary oxalate by simultaneous using Sankol herbal drop with oxalate-degrading bacteria.

Background And Objectives: Oxalate degrading bacteria and herbal extracts are new strategy for reducing hyperoxaluria. In Iranian traditional medicine, Sankol oral drop is widely used as an antispasmodic drug to reduce stones from urinary tract. This study aimed to evaluate the synergistic effect of oxalate-degrading bacteria and Sankol oral drop in reducing urinary oxalate in rat model.

Materials And Methods: Several bacterial strains, including (4), (2) and (2) (very strong in degrading oxalate ) were used in this study. Male Wistar rats were divided into 6 groups (n = 6). The rats of Group I received normal diet and drinking water + 60% ethanol (positive group). Groups II (negative group), III, IV, V, and VI rats received diet containing ethylene glycol (3%) for 30 days. Groups III rats received Sankol with minimum concentration (7.5 ml/kg/b.w), Group IV rats received Sankol with maximum concentration (9 ml/kg/b.w), Group V rats received Sankol with minimum concentration + probiotic, and Group VI rats received Sankol with maximum concentration + probiotic for 30 days.

Results: Treatment with Sankol (maximum concentration) and oxalate-degrading probiotic bacteria significantly reduced urinary oxalate ( = .0001). At the end of treatment period, rats in groups II (negative control) showed a high score of CaOx crystal, while rats in VI groups did not show any CaOx crystal.

Conclusion: This is the first study on the simultaneous use of Sankol herbal drop and oxalate-degrading probiotic bacteria that showed a significant reduction in urinary oxalate.
