The presence of osmiophilic, lamellated bodies in cells of the pulmonary surface epithelium of both immature and mature animals now is established. Such inclusions were described first by Schlipk6ter (1954), and there have been numerous reports of their presence in the lungs of many mammals and in the gill epithelium of amphibia and fish (e.g., Campiche, 1960; Policard et al., 1957). There have...

Owing to its unique surface-active properties, an exogenous pulmonary surfactant may become a promising drug delivery agent, in particular, acting as a vehicle for antibiotics in topical treatment of pneumonia. The purpose of this study was to assess a mutual influence of natural surfactant preparation and three antibiotics (amikacin, cefepime, and colistimethate sodium) in vitro and to identif...

In this paper, covalent immobilization of beta amylase enzyme on the surface of modified magnetic nano particles (ZnFe2O4@SiO2-NH2) is reported. For doing so, at first, the magnetic nanoparticles of ZnFe2O4 were synthesized by chemical co-precipitation method and then tetraethyl orthosilicate (TEOS) and 3-aminopropyltriethoxy sil...
