Inhibition of CaOx crystals by Neolamarckia cadamba: An in vivo approach

Abstract

AbstractThe objective of the study was to find out the effectiveness of the methanol fruit extract of N. cadamba on calcium oxalate induced nephrolithiasis in wistar albino rats. Animals were divided into nine groups (n=4) in which group 1 as control, group II as antilithiatic control and group III as lithiatic control. Dose for the methanol fruit extract was selected for the study as 200 and 400mg/kg body weight of fruit extract. Group IV and V were considered as post treatment groups and group VI to IX were co treatment groups. Ethylene glycol in drinking water was given to group II - IX for the induction of renal calculi. All the stone forming constituents such as urea, uric acid and creatinine were reduced significantly (p<0.01) in the extract treated groups. Calcium, oxalate and phosphorous concentrations in kidney were found to be diminished by the supplementation of extract. ICP-MS analysis, Histopathology, microcrystal study and pizzalato’s staining confirmed the efficacy of the fruit extract. In conclusion, the results suggested that the fruit extract is endowed with the property of an antilithiatic drug.
