Efficacy of Ficus spp. on renal injury induced by hypercholesterolaemia

The ethanol and hexane extracts of Ficus microcarpa, Ficus religiosa and Ficus mysorensis leaves were evaluated against renal injury induced by hypercholesterolaemia. Phytochemical screening of the investigated plants was undertaken. For the in vivo study, all rats were orally given cholesterol (30 mg kg(-1) body weight, BW) and leaves extract (500 mg kg(-1) BW) five times per week for 9 weeks. Hypercholesterolaemic rats showed significant increases in urea nitrogen and creatinine while serum protein and albumin levels, nitric oxide (NO), Na+-K+-ATPase and phospholipids in kidney tissue were all decreased. Treatment with leaves extract improved kidney function indices (urea nitrogen, creatinine, serum protein and albumin), kidney disorder biochemical parameters (NO, Na+-K+-ATPase and phospholipids), haematological profile (haemoglobin, RBCs and WBCs) and kidney histopathology. In conclusion, Ficus spp. succeeded in improving renal injury induced by hypercholesterolaemia, with the most potent effects seen while using Ficus microcarpa hexane extract.
