PLA₂ activity of lung homogenate from male and female mice measured at varying times after i.v. (A) or i.t. (B) injection of MJ33 (0–10 nmol) in liposomes. PLA₂ activity was measured by assay in Ca²⁺-free medium, pH 4. Results are mean ± S.E. for n = 3–5. *P < 0.05 versus control (no MJ33) for each time point.
