INTRODUCTION
Nitric oxide (NO) is synthesized from the amino acid
L-arginine by nitric oxide synthase (NOS). Activated macrophages
releaseNO, a toxic radical that causes cellular alterations,
including mutations in DNA, cell apoptosis, and necrosis, that
lead to diseases such as cancer and atherosclerosis (1). A large
amount of NO is produced in response to lipopolysaccharide
(LPS), which plays an important role in inflammatory conditions
(2). Levy et al. (3)
