Lipoic acid (LA) is a natural antioxidant and possess beneficial effects on oxidative stress parameters in various tissues.
The aim
of the study was to estimate of influence of LA on free -SH groups and TNF-α levels in spleen homogenates in rats during oxidative stress induced by LPS.
Material and methods
. Experiments were performed on Wistar rats devided into 4 groups: group I (control) received 0,9% NaCl; group II – received LA (100 mg/kg); group III received LPS (10 mg/kg); group IV – received LPS (10 mg/kg) and 30 min later received LA at the dose 100 mg/kg.
Results
. Administration of LA after LPS-induced oxidative stress resulted in statistically significant increase in the level of -SH groups and decrease in the level of TNF-α when compared to the LPS group (p< 0.001).
Conclusion
. The early administration of LA after LPS challenge a significant suppressed symptoms of oxidative stress and inflammatory effects LPS, expressed as a increase in -SH groups and decrease in TNF- in the spleen homogenates.

Key words: lipoic acid, spleen, TNF-α
