title: Lipid pattern and Na(+)-K (+)-dependent adenosine triphosphatase activity in the salt gland of duck before and after adaptation to hypertonic saline.
abstract: Ducks (Anas platyrhynchos) were fed hypertonic saline for eight days, resulting in an activation and hypertrophy of the salt gland. The Na(+)-K(+)-dependent adenosine triphosphatase, an enzyme generally assumed to be part of the active Na transport system, increased its specific activity by about 200% during this activation. Sulfatides, the major glycolipids of the salt gland, increased their concentration to the same extent. Cholesterol, cerebrosides, and six phospholipid classes showed an increase of 20-80%.
