“…the number of pituicytes within) the neural lobe would interfere with the functional response. During water deprivation and lactation of the rat, however, an increase in mitotic activity (ORTMANN, 1951 ;MALAN-nRA, 1956) and an increase in neural lobe volume (LFGAIT, 1964(LFGAIT, , 1971 pointed to an increased number of pituicytes. And this fact would underrate rather than overrate the lysosomal change expressed per unit DNA.…”

—The activities of five lysosomal enzymes, acid phosphatase, β‐glucosidase, β‐glucuronidase, β‐galactosidase and N‐arylamidase (classified according to Marks (1970)) were measured by means of sensitive microchemical techniques in frozen‐dried rat neural lobe tissue after experimental and physiological stimulation of hormone release from the hypothalamo–neurohypophysial system i.e. water deprivation (3 and 6 days), delivery and lactation (10 days). During all conditions of stimulation increases of 29 to 106 per cent were measured for lysosomal enzyme activity, expressed as mmol/ng DNA/h. With histochemical staining methods the acid phosphatase activity appears to be mainly localized in the pituicytes, but it was impossible to visualize the microchemically measured acid phosphatase activity increase within the two main compartments of the neurohypophysis, i.e. axonal endings and the neurohypophysial glial cells, the pituicytes.
