Nephro-protective potential of Morus alba, a prospective experimental study on animal models

Context: Morus alba L. (Moraceae) is traditionally used for the treatment of urinary incontinency due its strong diuretic properties. Objective: The present study explores the renal protective effects of M. alba, due to its free radical scavenging properties, in order to provide experimental evidence for its established use. Materials and methods: Ethanolic extract (200mg/kg/d) derived from M. alba fruit was employed in rabbits as a co-therapy (GM-al) with gentamicin (80mg/kg/d) for a period of 3weeks. Biochemical kidney functioning parameters, urinary isozymes, and histopathological examination were performed. Results: The results showed that ethanol extract of Morus alba L. prevented alterations in serum creatinine (4.02 +/- 0.14, p<0.0001), blood urea nitrogen (54.18 +/- 2.60, p<0.0001), and serum uric acid levels (2.34 +/- 0.12, p<0.001). However, a decrease in creatinine clearance and urinary volume was observed in experimental groups. Histopathological examination and urinary enzymes excretion also suggested the protective role of the extract. Discussion and conclusions: The co-administration of M. alba with gentamicin prevented renal functioning alterations expected with the use of gentamicin alone. Therefore, it can be concluded that M. alba to protect from kidney damage, which may be because of its free radical scavenging and diuretic properties.
