Abstract
|
|
|
|
The cobalt capture method of Gomori's modified technique(Gomori, 1952) was employed to study the histochemistry of the developing frog kidney. Alkaline phosphatase activity was observed in association with the brush borders of pronephros and mesonephros. By the stage of transition from larva to tadpole alkaline phosphatase activity was gradually increased in the brush border of pronephros, and as the pronephros begun to degenerate the enzyme activity was decreased and disappeared. By the time of maximum development of the pronephros the mesonephros began to develop and alkaline phosphatase activity of the mesonephric tubules showed highly positive throughout the stage of metamorphosis. No activity was observed in association with the collecting tubules and ductal elements.
