Valproic acid (VPA) is commonly used in the treatment of epilepsy, but serious complications may
occur in some patients, including hemorrhagic pancreatitis, coagulopathies, bone marrow suppression,
VPA-induced hepatotoxicity and encephalopathy. Moringa oleifera leaves are widely used in many
tropical countries, as a good source of antioxidant compounds such as ascorbic acid, flavonoids and
phenolics. Studies on the biological effects of M. oleifera have shown that the plant has potential
antitumor, anti-inflammatory, antiulcer, antispasmodic, diuretic, antihypertensive, antidiabetic and
hepatoprotective effects. The current study was designed to investigate the effects of moringa leaves
extract (70% ethanol) on antioxidant system against VPA-induced oxidative damage in muscle tissues
of rats. In the study, female Sprague Dawley rats were randomly divided into four groups. Group I:
control group (n=8); Group II: animals given only 70% ethanol extract of moringa leaves for 15 days
(0.3 g/kg b.w. /day) (n=8); Group III: animals that received only sodium valproate for 15 days (0.5 g/kg
b.w. /day) (n=15); Group IV: animals administered with similar dose of sodium valproate+moringa
extract for 15 days (n=12). Moringa extract and sodium valproate were administered orally. Group I was
orally given a similar dose of physiologic saline. At the end of the experiment, muscle tissues were
taken. Total antioxidant (TAS), total oxidant (TOS), reactive oxygen (ROS), oxidative stress index
(OSI), nitric oxide (NO), sialic acid (SA), glutathione (GSH), lipid peroxidation (LPO) levels, lactate
dehydrogenase (LDH) and myeloperoxidase (MPO) activities were determined in muscle tissues. In
VPA groups, TOS, ROS, OSI, NO, SA, LPO levels, LDH and MPO activities were found to be raised,
while TAS and GSH levels diminished. Administration of M. oleifera extract reversed these changes.
These results showed that M. oleifera leaves extract had a protective effect on muscle tissues against
VPA damage.
