METHODS: Fifty Wistar rats were used and divided into: control group (C), sham group (S), ischemic group (I), alco...
Background: due to widespread applications of nanoparticles in biomedicine and biotechnology and their effects on human health, the present study was conducted to determine the cytotoxic effect of CuO nanoparticles on serum biochemical parameters and liver histopathological changes of NMRI mice. Methods: In this experimental study, forty two female NMRI mice were randomly divided into six group...
Background: Corn silk (CS) is widely used in Iranian traditional medicine. The aim of this study was to investigate hepatoprotective activity of CS by Isolated Rat Liver Perfusion System (IRLP). Methods: Hydro-alcoholic extract of corn silk (10, 20, 40, and 100 mg kg-1) was evaluated for its hepatoprotective activity by IRLP. Phenol and flavonoid contents of the extract were determined as gal...
