Exogenous administration of SOD/CAT or SOD overexpression in animal models of hyperoxic lung injury (modified from [43]).

Models Administration or technique details Outcomes Reference

Rats, hyperoxic Formulation: liposome-encapsulated bovine SOD and CAT
Route: IV
Timing: before and during exposure
Increased survival rate and reduced pleural effusion in the treatment group versus saline[44]

Rats, hyperoxic Formulation: liposome-encapsulated bovine SOD and CAT
Route: ET
Timing: before exposure
Increased survival rate and preserved lung histology in the treatment group versus controls.[45]

Piglets, hyperventilated and hyperoxicFormulation: rhSOD
Route: ET
Timing: at start of exposure
Reduced neutrophils chemotactic activity, total cell count, elastase activity, and albumin in tracheal aspirates versus controls.[46]

Rabbits, lung tissue challenged with xanthine and xanthine oxidase Formulation: liposome-encapsulated bovine SOD and CAT
Route: ET
Preserved lung filtration coefficient in treated animals versus controls.[47]

Transgenic mice, hyperoxicLung-targeted SOD3 overexpressionReduced lung neutrophils and oxidized GSH, increased alveolar surface and lung volume density in transgenic animals versus wild-type controls. [48]

Transgenic mice, hyperoxicLung-targeted SOD3 overexpressionPreserved alveolar and bronchiolar epithelium proliferation, reduced DNA damage, and preserved apical protein expression on type I cells in transgenic animals versus wild-type controls.[49]

Rabbit, hyperoxicTransfection with rhSOD3 containing plasmid
Route: AER
Increased lung cGMP and decreased lung NF-kB expression in transfected animals versus controls.[50]

Transgenic mice, hyperoxicLung-targeted SOD3 overexpression + Antileukinate for 7 days
Route: IP
Reduced lung neutrophils, 8-isoprostane, and oxidized GSH and reduced myeloperoxidase activity in tracheal aspirates of treated transgenic animals versus treated wild type or untreated transgenic animals.[51]

IV: intravenous; ET: endotracheal; IP: intraperitoneal; AER: aerosolized.
