Renin release and the juxtaglomerular apparatus in chronic renal failure due to glomerulonephritis

Changes in renin release with decreasing renal function and juxtaglomerular apparatus in chronic renal failure due to glomerulonephritis were studied. Renin production was still remaining in the contracted kidneys and its release could be stimulated by various stimulations, although the macula densa didn't seem to play an important role in renin release in the contracted kidneys.
