摘要：

1. 1. Intestinal glycosidase activities of six individual seals of three different species (Tasmanian and New Zealand fur seals, Southern Elephant seal) were investigated. 2. 2. Pancreatic amylase and intestinal lactase and o-nitro-phenyl-β-galactosidase activities were present at very low levels in all the seals, including a suckling pup. Maltase and isomaltase activities were lower than those of other mammals. Sucrase and trehalase were absent. 3. 3. Seal erythrocyte hexose-1-phosphate uridyltransferase and UDPglucose pyrophosphorylase activities were similar to those of normal human erythrocytes. 4. 4. A sample of Tasmanian fur seal milk was analysed. It was found to contain a trace only of lactose. © 1968.
