Abstract
Changes in extra and intracellular neurotransmitter amino acids concentration in the early stage of acute cerebral
ischemia have been reported. In this the study, serum level of gamma aminobutyric acid (GABA) and L-
Arginine in acute ischemic stroke patients was assessed. 60 patients with acute ischemic stroke and sixthy
healthy volunteers as a control group were assessed. Serum GABA was measured with modified enzymatic
method and serum L- Arginine was measured by modified Sakaguchi method. Serum GABA level in stroke
cases was lower than that of the control group. There was no relationship between GABA level and age or
gender. Also, no significant correlation was observed between GABA levels with ischemic stroke risk factors
such as smoking, diabetes mellitus, and hypertension. Serum L- Arginine level in patients was slightly increased
in comparison with control group. There was a positive relationship between serum L- Arginine level and acute
ischemic stroke risk factors. Serum GABA level was reduced in patients and had no correlation with acute
ischemic stroke risk factors.
