The presence of surfactant proteins was investigated in the human organ of Corti, Eustachian tube and kidney tissues. It has previously been shown that lamellar bod­ies are present in hairy cells of organ of Corti, in the cytoplasm of secretory and lu­men of tubal glands of Eustachian tube and kidney renal basement membrane. No evidence for the presence of surfactant proteins in the organ of Corti and kidney has been presented until now. The aim of this study was to find out if surfactant proteins were expressed in other epithelia such as organ of Corti, Eustachian tube and kid­ney. Surfactant proteins were identified using one-dimensional sodium dodecyl sul- fate-polyacrylamide gel electrophoresis and Western blotting. On one-dimensional Western blots, bands for surfactant protein A in human Eustachian tube (SP-A, 34 kDa) and in kidney extracts, and for surfactant protein D (SP-D, 43 kDa) in Eusta­chian tube and in kidney extracts (SP-D, 86 kDa), and for surfactant protein B (SP-B, 8 kDa) in human Eustachian tubeand organ of Corti extracts were detected. Bands corresponded to monomeric forms of lung surfactant proteins. These results indicate the presence of SP-A and SP-D in kidney epithelium, SP-A, SP-B and SP-D in Eusta- chian tube and SP-B in the organ of Corti.
