Resumen

Angiotensin I converting enzyme activity was measured in homogenates of guinea pig and chicken organs (lung, kidney, heart, ileum, diaphragm and liver), using a spectrophotometric assay for hydrolysis of hippuryl-L-histidyl-L-leucine. High specific activities were found in lung, kidney and diaphragm, but the highest corresponded to guinea pig lung and chicken kidney. Acute hypoxia decreased angiotensin I converting enzyme activity in guinea pig lung and chicken diaphragm, but the changes in kidney were considered non-significant in both the guinea pig and chicken.
