Doctor Bernstein has utilized a most ingenious approach to the subject. He starts with normal renal function, and by using simple, clear diagrams explains the physiology of the nephron at different sites. He goes on to discuss the methods of formation of different solutions of water and electrolytes, and the remarkable ability of the kidney to adapt itself to wide physiologic variations. The author then presents a working concept of renal reserve which he ties in with a discussion of body composition and the differential diagnosis of azotemia. In the final chapter, there are discussions of fluid and electrolyte replacement therapy and of derangements in ion concentrations.
