Reckoning of antiurolithiatic effect of Flemingia Strobilifera R. BR using ethylene glycol-induced urolithiatic animal model: demystifying traditional medicine

Abstract

Background Urolithiasis is a painful condition and current treatment doesn’t assure the prevention of recurrence. This research aims to demonstrate the scientific reliability of Chloroform leaf extract of Flemingia Strobilifera R.Br. (CEFS) for antiurolithiatic activity using ethylene glycol-induced urolithiasis model. Results Ethylene glycol (EG) was used to induce hyperoxaluria in male Wistar rats. The rats were grouped into 7-groups containing six each. Group I and II served as negative and positive control, group III received standard treatment, whereas Group IV to VII served as testing groups. CEFS of 30 mg/kg body-weight and 60 mg/kg body-weight was used as a preventive and curative regimen. The urine biochemistry was analysed for the presence of calcium, magnesium, phosphate, and oxalate. The rats were sacrificed for histopathological examination and LDH detection. The 24-hours urine volume was increased in both EG-treated groups as well as CEFS-treated groups, indicating the diuretic activity of plant. CEFS dose-dependently inhibited urine excretion of phosphate, calcium, and oxalate compared to the positive-control group. The histopathological examination of CEFS-treated rats’ kidneys had reduced loss of renal structure and lessened deposition of calcium oxalate crystals. Conclusion CEFS exhibited significant antiurolithiatic activity by reducing supersaturation of urine and excretion of stone forming components.
