Time dependent effect of laminarin induced release of H₂O₂ by haemocytes. An increase in H₂O₂ production was detected when animals received a bolus injection of laminarin 3 hrs before hemocyte collection in comparison with their time corresponding vehicle treated animals. Injection of laminarin 0.5 hr, 1 hr or 24 hrs before measurement failed to detect any differences in H₂O₂ release between the laminarin treated groups and their time corresponding vehicle treated animals. * = p < 0.05.
