The contribution of pancreas and kidney in regulating serum amylase levels in dogs.

Amylase activity in canine serum before and after total pancreatectomy with or without additional removal of duodenum and other small intestines were determined and resulted that pancreas would provide approximately fifty per cent of amylase detected in the canine serum. Serum amylase levels were also measured before and after intravenous injection of canine pancreatic juice as a source of pancreatic amylase into normal or nephrectomized dogs in order to investigate the mode of disappearance of amylase from circulating blood and following result was obtained that intravenously injected amylase were removed from the blood of extraurinary mechanism in dogs.
