INANITION AND MALNUTRITION 



In adult albino rats, the cells in the various cortical zones of the suprarenal 

 appeared variably atrophic in acute or chronic inanition (Figs. 107 and 108). 

 The atrophy occurs chiefly in the cytoplasm, increasing the nucleus-plasma 

 ratio. The pigment remains unchanged. The fat granules (liposomes)

 Formalin fixation; frozen section stained with Herxheimer's scarlet red. Liposomes are most 

 abundant in the outer cortical zone and the outer half of the middle zone. F, fibrous capsule; 

 with large fat droplets in the tissue outside; 0, outer zone (glomerulosa) ; T, transition band, 

 relatively lipoid-free; Mo, outer part of the middle zone (f asciculata) ; Mi, inner part of the 

 middle zone; I, inner zone (reticularis); M, medulla. X90. (Jackson '19.)

may persist for a considerable period, and even appear more extensively and 

 uniformly distributed than normally (Figs. 109, no); but in extreme stages they 

 are usually greatly reduced, though persisting tenaciously in the outer zone 

 (Figs. 108, in).
