Figure 3.

Effects of incubation time (2 – 12 h) with LPS on aggregation of whole blood induced by collagen (5 μg ml⁻¹) or U46619 (5×10⁻⁷ M). The data shows responses, performed in parallel, of blood incubated with or without LPS and then stimulated with aggregatory agent. Each set of single responses was performed using blood donated by n of five separate individuals. ^*Illustrates a statistical difference in the responses of blood treated with LPS compared to control calculated using two-way ANOVA. A P value of less than 0.05 was taken to be significant.
