Effect of Ethanolic Extract of Emblica officinalis on Histopathology of Kidney and on Biochemical Parameters in Hyperlipidemic Albino Rats

Abstract

Background: It has been reported that hyperlipidemia plays a central role in the development of atherosclerosis and oxidative stress. Embilica officinalis also known as Amla or Indian Gooseberry acts as antihyperlipidemic and antioxidant. Its active ingredients contains tannins, gallic acid and flavonoids. Aim & Objectives: It was aimed to evaluate the effect of ethanolic extract of Emblica officinalis on histopathology of kidney and on biochemical parameters in hyperlipidemic albino Wistar rats. Material and Methods: Extraction of dried fruits of Emblica officinalis was done by Soxhlet apparatus 0 using 99% ethanol at 60 C for 24 hours and also phytochemical analysis was done. Group I served as normal control. Group II was fed with isocaloric diet. Group III was fed with hyperlipidemic diet. Group IV was fed with isocaloric diet for 21 days + Embilica officinalis for 21 days. Group V was fed with hyperlipidemic diet for 21 days+ Embilica officinalis for 21 days. The dose of ethanolic extract of Emblica officinalis was taken as 100mg/kg body weight daily. Results: Percent body weight gain, kidney weight and nephro-somatic index significantly improved in hyperlipidemic rats treated with Emblica officinalis. There was a significant improvement in serum electrolyte and kidney markers. It was found that there were focal glomerular lesions with thickening of glomerulus in the kidneys of rats on hyperlipidemic diet and normal renal histology of rats on hyperlipidemic diet treated with Emblica officinalis. Conclusion: It can be concluded that Emblica officinalis may be a good, natural therapeutic agent against hyperlipidemic diet induced oxidative damage and nephrotoxicity.
