Oxidative damage plays a key role in septic shock induced by the endotoxin lipopolysaccaride (LPS) by enhancing the formation of reactive oxygen species such as superoxide anion radicals, peroxides, and their secondary product, malondialdehyde, especially in the liver. In this study, histopathologic
The immunoreactivity of inducible nitric oxide synthase, and cyclooxygenase-2 was compared among groups of male Wistar rats comprising those injected with lipopolysaccharide following pretreatment with either natural antioxidant from spinach or the antioxidant apocynin, with lipopolysaccharide
Radical-scavenging antioxidants, as part of the cellular defense system, function to inhibit the formation and propagation of free radicals and active oxygen species formation. In previous studies we demonstrated that endotoxin lipopolysaccharide (LPS) promotes oxidative stress and associated
Oxidative damage plays a key role in septic shock induced by lipopolysaccharide (LPS) which is known to enhance the formation of reactive oxygen species (ROS). In this study, biochemical parameters indicative of oxidative stress were tested in the rat heart following LPS challenge, with and without
The objective of this study was to compare the prophylactic effects of the natural antioxidant from spinach (NAO) and apocynin, on the hepatic oxidative stress and liver damage induced by lipopolysaccharide (LPS). Male New Zealand rabbits were challenged with LPS with or without 8 days of
