SRT@ attenuated lipopolysaccharide-induced release of the cytokines interleukin-@ ( mean peak levels of @ % -LSB- p < @ -RSB- and @ % -LSB- p = @ -RSB- after single and repeated SRT@ administration , respectively , relative to those measured after placebo treatment ) and interleukin-@ ( mean peak levels of @ % -LSB- p < @ vs placebo -RSB- and @ % -LSB- p < @ vs placebo -RSB- after single and repeated SRT@ ingestion , respectively , while not affecting tumor necrosis factor - and interleukin-@ release ) .
