Summary: | To evaluates the antioxidant and hepatoprotective
potentials of Dicoma anomala Sond.
(Asteraceae) on body weight, feed and water intake,
biochemical parameters and organ histology.
Various concentrations (1.56-25 μg/mL)
were used in the in vitro assays 1,1-diphenyl-2-picryl
hydrazyl (DPPH, superoxide anion, hydroxyl radicals,
etc.). The effects of treatment with 125, 250
and 250 mg/mL Dicoma anomala aqueous roots extract
(DARE) was investigated in vivo in the CCl4-induced
hepatotoxic rats during the 15 days study.
Water extract exhibited the best activity
(IC50: 15.20 ± 0.03, 11.70 ± 0.10, and 0.84 ± 0.05 μg/
mL) in vitro in DPPH, hydroxyl and superoxide anion
radicals, respectively, when compared with
standards. Pre-treatment and treatment with different
concentrations of DARE significantly (P < 0.05)
attenuated the elevated serum activities of aspartate
transaminase, alanine transaminase levels
while increasing the activities of superoxide dismutase,
catalase and glutathione peroxidase. The
histopathological evaluations revealed extensive
liver damage characterized by severe vacuolar and
cytoplasmic degeneration, hepatic necrosis, and
cellular infilteration in pre-treated groups while in
the treated groups; such liver damages were not
observed most especially at 500 mg/kg dose.
The results proved the hepatoprotective
potential of DARE against CCl4-induced oxidative
stress. Moreover, histopathological examinations
revealed better therapeutic advantage of
DARE than prophylactic use. |
