Sorbitol dehydrogenase in Anas platyrhynchos and Zenaida auriculata auriculata during development

Sorbitol dehydrogenase (E.C.N. 1.1.1.14) was studied in liver, kidney and gonads of Zenaida auriculata auriculata (golden pigeon) and of Anas platyrhynchos (creole domestic duck) from South American faunes. The specific activity of SDH increased from embryonic to adult stage and is higher in the Anas platyrhynchos tissues. The electrophoretic studies performed in liver and kidney of both species during development showed variations in the number and intensity of the bands in accordance with the age and the species.
