X300. For explanations, see Fig. 105. The lipoidal vacuoles have disappeared, except in the outer zone (0). There is marked atrophy with nuclear and cytoplasmic degeneration in the inner cortical zone (7). Three pigment masses (P) are visible. (Jackson '19.) changed during inanition. Hyperemia is marked in the zona reticularis. In young rats during underfeeding the change in size of cortical cells and nuclei is variable, some increasing, some decreasing, some remaining unchanged. The cortical cells develop liposomes (as normally) but in variable amount (Figs. 105 and 106). In some cases, many cells undergo atrophic degeneration, especially toward the inner zone. Pigment appears in unusual abundance. Mitosis is more or less completely suppressed, but upon refeeding it is resumed, and normal conditions are nearly restored in two weeks.
