Abstract

The aim of this study was to evaluate the protective effects of hydroethanolic extracts of S. scabrum and C. verticillata against cyclophosphamide induced toxicity. In this light, female albino wistar rats were treated by intraperitoneal administration of 100 mg/kg BW of cyclophosphamide or distilled water every other day for 7 days associated with oral gavage using hydroethanolic extract of C. verticillata/S. scabrum at a dose of 200 or 400 mg/kg BW or not every day for the same 7 days. On the 8th day, blood and organs (liver, heart and kidney) were collected for analyses of toxicity-related and oxidative stress markers. Cyclophosphamide treatment induced significant toxicity as shown by liver enzymes, urea and creatinine levels. The administration of extracts helped reduce the levels of these markers. The antioxidant effect of these extracts also helped or not to ameliorate oxidative stress markers (MDA, NO, hydroperoxides, catalase, thiols, GPx) depending on the extract and on the dose administered. These results suggest that administration of hydroethanolic extracts of S. scabrum and C. verticillata can help prevent or reduce toxicity that is brought about by treatment with cyclophosphamide due to their ability to upregulate antioxidant mechanisms.
