Figure 3From: Immunomodulation of murine collagen-induced arthritis by N, N-dimethylglycine and a preparation of Perna canaliculus Perna extract inhibits superoxide production and burst activity by neutrophils. Rat neutrophils were isolated from peripheral blood and stimulated with PMA (50 ng/ml) in the presence of increasing concentrations of Perna extract. Percent inhibition was calculated by comparing Perna extracts with untreated cells. * indicates a p-value < 0.05.Back to article page
