A. DRUKKER. 1974. THE RENIN- ANGIOTENSIN SYSTEM IN NEWBORN DOGS; 



Developmental patterns, response to saline load and relation to intrarenal haemodynamics 



and so'dium excretion during maturation 



M. D. thesis, Utrecht. XII, 153 pp., 41 figs., 11 tabs. 



In puppies from birth to three weeks of age the following parameters were studied: 

 plasma renin activity (radio-immunoassay), intrarenal distribution of blood flow (xenon 

 washout and krypton autoradiography), glomerular filtration rate, and fractional excre- 

 tion of sodium (the latter three during saline diuresis); 60-page literature review with 

 emphasis on developmental aspects.

 extensive literature discussions also consider development; emphasis in results on morpho- 

 logy and fine structure; numerous good light and electron micrographs.
