Fig. 2. Effect of mosquito salivary gland homogenates (SGH) on PAF-induced platelet aggregation of human platelets. (A) Platelet aggregation tracings in the absence (control, open squares) or presence of 0.5 pairs of homogenised salivary glands of Aedes aegypti (filled triangles) and Culex quinquefasciatus (circles). (B) Effect of the amount of Culex quinquefasciatus SGH preincubated with PAF for 1 min (filled circles) or 20 min (open circles) and Aedes aegypti (filled triangles) preincubated with PAF for 1 min, on PAF-induced platelet aggregation. Inhibition of the aggregation was estimated at 5 min after start of the assay. Values are means ± S.E.M. of three determinations. For more details, see Materials and methods.
