aiPLA₂ activity of mouse lung after injection of PIP-2. Mice were anesthetized and injected intravenously with PIP-2 at 2 µg/g body wt. Lungs were analyzed 2 h later for aiPLA₂ activity. Results are mean ± SD for n = 3. * p < 0.05 vs. Control and vs. PIP-2 mixed with phosphate buffered saline (no liposomes).

	aiPLA2 Activity nmol/hr/mg Protein
Control (Liposomes only)	8.81 ± 0.42
PIP-2 (Encapsulated in Liposomes)	1.55 ± 0.03 *
PIP-2 (No Liposomes)	8.43 ± 0.40
