Endogenous Kallikrein Inhibitor in Rat Kidney Cortex-Effect of Glucocorticoid Administration
Kallikrein inhibiting proteins with two different molecular weight (6-8 × 104, 8-9 × 104 respectively) were observed in adrenalectomized rat kidney cortical soluble fraction. The larger one was observed in the kidneys of the adrenalectomized rats only when they had received chronic administration of excess amount of dexamethasone, and its kallikrein inhibitory activity was not lost with treatment with trypsin. This protein appears to be induced by chronic administration of glucocorticoid and might participate in the process of glucocorticoid regulating renal kallikrein kinin system.
