Abstract
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 x 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.
