INANITION AND MALNUTRITION 



Fig. 97. — Photograph of a portion of a section from the kidney of a normal adult albino 

 rat (S. 14), showing two renal (Malpighian) corpuscles and the adjacent cortical labyrinth 

 (chiefly proximal convoluted tubules). Compare with Fig. 98. Zenker fixation; hematoxylin- 

 eosin stain. X250.

Fig. 98. — Photograph of a portion of a section from the kidney of an adult albino rat 

 (S. 18), after 8 days of inanition on water only, with loss of 38 per cent in body weight. Esti- 

 mated loss of about 26 per cent in weight for the kidney. Compare with Fig. 97, noting the 

 apparent shrinkage of the renal (Malpighian) corpuscles and tubules. The cells show atrophic 

 degeneration, with nuclear pycnosis or karyolysis. Zenker fixation; hematoxylin-eosin stain. 

 X250.
