[Ultrastructural changes in loose connective tissue histiocytes in dehydration and starvation]

Changes in the parameters of the volumetric fractions of the main cytoplasmic organellae were studied in the subcutaneous connective of albino rats subjected to experimental dehydration and starvation. There were some common features in the histiocytes reaction under these conditions, i. e. hypertrophy of the lysosomal apparatus and cell "infiltration" with lipids. At the same time the following differences are emphasized: dehydration caused an increase of the volumetric mitochondrial fractions and of the rough endoplasmic reticulum, and starvation of the phagosomal fraction.
