Hepatotoxic and hematotoxic effects of sage oil-loaded ifosfamide nanoemulsion in Ehrlich ascites carcinoma-bearing mice

摘要

Purpose: To investigate the hepatotoxic and hematotoxic effects of sage oil-loaded ifosfamide (IFO) nanoemulsion (NE) in Ehrlich ascites carcinoma (EAC)-bearing mice. Methods: Ifosfamide (IFO) was loaded into a NE containing sage oil, and its hepatotoxic and hematotoxic effects were assessed in EAC-bearing mice. Female Swiss albino mice (n = 50) weighing 25 - 30 g (mean weight = 27.5 ± 2.50 g) were randomly assigned to five groups of ten mice each. With the exception of group 1, the mice were inoculated intraperitoneally (i.p.) with 2.5 × 10 6 EAC/mouse for 48 h. Group I served as negative control, C (-); group II served as positive control, C (+); while groups III - V were treated i.p. with 60 mg/kg IFO in 0.3mL water (free-IFO); 0.3 mL NE (SAGE-NANO), and 60 mg/kg IFO in 0.3 mL SAGE-NANO (SAGE-IFO), respectively. The treatments were administered for three days. Results: Treatment with 60 mg/kg bwt IFO (free-IFO) significantly elevated the activities of aspartate aminotransferase (AST) and alanine aminotransferase (ALT, p 0.05). However, subsequent treatment with SAGE-IFO significantly reduced the activity of these liver enzymes (p 0.05). The concentration of reduced glutathione (GSH) as well as the activities of catalase and glutathione reductase (GR) significantly increased, while malondialdehyde (MDA) level decreased significantly in SAGE-IFO group, when compared with free-IFO group (p 0.05). Treatment with SAGE-IFO significantly restored white blood cell (WBC) count and platelet levels which were altered by free-IFO (p 0.05). Conclusion: The results obtained in this study suggest that loading IFO in sage oil-NE greatly reduces its hepatotoxicity and hematotoxicity.
