The therapeutic efficacy of single-dose intratracheal dexamethasone (2.5 mg/kg) in oleic acid-induced acute lung injury in the rat was established by showing significant improvement in bronchoalveolar lavage parameters and lung compliance at 24 h after oleic acid as compared with animals not treated with oleic acid. An equivalent dose of intraperitoneal(More)
A series of racemic 16:0 disaturated N-substituted diether phosphonolipid analogs of glycerophospholipids have been synthesized and purified. Isosteric methylene substitution at three of the four ester sites (carboxyl, phosphate) of conventional glycerophospholipids enhanced the hydrophobicity of analog compounds compared with dipalmitoyl(More)
Increased activities of phospholipase A2 and C (PLC) have been observed in the bronchoalveolar lavages of patients with adult respiratory distress syndrome (ARDS). DL-alpha-Di-O-hexadecylphosphonocholine [(R)(S)-DEPN-8], a surfactant analog of superior surface activity to the major lung surfactant phospholipid, dipalmitoylphosphatidylcholine (DPPC), is not(More)
Increased phospholipase A2 activity demonstrated in some forms of lung injury may contribute to surfactant dysfunction. Phospholipase A2-resistant analogs of dipalmitoylphosphatidylcholine (DPPC) with surfactant properties might therefore be useful lipid components of treatment surfactants for certain lung injuries. The in vivo function of surfactants(More)
A homologous series of chiral (R) ether-amide phosphonolipid analogs of naturally occurring (R) glycerophospholipids were synthesized and characterized for their interfacial behaviors. The phosphonolipids possess isoteric ether, amide, and phosphonate functions at positions corresponding to the sn-1, sn-2, and sn-3 ester functions, respectively, of(More)

Digital technologies is showing tremendous growth and advancements in image transmission and processing during last few years. The image security during image transmission is one of the important areas for research. Various digital watermarking techniques are nowadays become popular for image security and copyright. But, due the rapid growth of the Internet(More)
We have developed a standardized in situ lung surfactant deficiency model in the rat by using a single bronchoalveolar lavage (BAL). The purpose of this study was to assess the usefulness of surfactants and surfactant analogs in terms of their in vivo physiological properties. Calf lung surfactant extract (CLSE) was shown to improve lung compliance in a(More)
