Introduction
Ischemic hypoxic brain injury causes irreversible brain damage by activating the
cascade of events such as release of cytokines and free radicals, and induction of
inflammation, apoptosis, and excitotoxicity which ultimately lead to neuronal injury and
death (Kuroda et al., 1997). Reperfusion of ischemic areas could aggravate ischemic brain
injury through the generation of reactive oxygen species. Moreover, a growing concern in
traditional medicines has raised due to lack of effective and widely applicable pharmacologi-
cal treatments for ischemic stroke.

Abstract
Lack of efficient and widely applicable pharmacological treatments for ischemic
stroke has necessitated attention towards novel traditional medicines. The effect of
Beta vulgaris (B. vulgaris) extract on neurobehavior, grip strength, serum lactate
dehydrogenase and brain SOD activity were studied at the dose of 250 mg/kg body
weight in right middle cerebral artery occlusion model. B. vulgaris extract signific-
antly improved the neurobehavioral function in rats after cerebral ischemia and
reperfusion, increased grip strength as compared to the MCAO group. Moreover,
treatment significantly boosted the defence mechanism against cerebral ischemia
by increasing SOD activity and decrease in serum LDH. These experimental results
suggest that extract of B. vulgaris may exert protective effect after cerebral
ischemia. Administration of extract significantly reduced focal cerebral ischemic/r-
eperfusion injury by augmenting antioxidants. Thus therapeutic strategies against
oxidative stress could serve effective in ischemic diseases.
