Fig. 2

The production of nitric oxide, by heat treatment for high, average and low immune responders. Cells were subjected to various heat treatments and nitric oxide production was measured by Griess assay. The data presented are least squared means + standard error of the mean. High immune responders are represented by the black bars, average immune responders by the grey bars and low immune responders by the white bars. P-values for significant effects or trends are presented in the figure. If a p-value is not present it indicates the effect is not significant
