Figure 3. Kinetics of leukotriene B4 (LTB4) release into the blood induced by Toxocara canis infection. Enzyme immunoassay of serum leukotriene concentration was performed 3, 6, 18, and 24 days after po inoculation of 1000 T. canis eggs (filled bars). Control uninfected rats received only 1 mL saline po (open bars). Data are reported as means ± SEM of at least 4 animals. *P < 0.05 vs control group (Student t-test).
