    Notes: Summary The chemiluminescence activity (CL-A; synonym=burst activity, BA) and the percentage of OKT3-, OKT4-and OKT8-positive peripheral blood cells were serially examined in four control persons and in eight patients with multiple sclerosis. When the OKT values obtained in phases of increased CL-A (clinical remission) were compared with those of the control group, the percentage of OKT3-positive cells was reduced (P=0.014), and that of OKT4-positive cells increased (P=0.014); there were no significant changes in the percentage of OKT8-positive cells (P=0.171). After the CL-A had returned to normal values, the OKT4-positive cells remained elevated (P=0.029), whereas the OKT3- (P=0.342) and OKT8-positive cells (P=0.443) showed no significant changes. When in the same patients, phases of increased CL-A were compared with phases in which values were not elevated, a reduced percentage of OKT3-positive cells was found in phases with increased CL-A (P=0.031); however, the OKT4-positive and OKT8-positive cells did not differ significantly (P=0.156 and 0.281).

    Notes: Summary In female Wistar rats the influence of adrenalectomy and NaCl administration on the amount of “classical” neurosecretory material (cNSM) in the supraoptico-hypophysial system and on vasopressin-like substance-containing granules (vlG) in the outer layer of the median eminence has been studied. In conjunction with appropriate sodium replacement, adrenalectomy induces an increase in the amount of vlG but does not alter the amount of cNSM. Administration of hypertonic saline diminishes cNSM but has no or only little influence on the amount of vlG. From the findings it is concluded that cNSM and vlG, in spite of their identical histochemical and immunohistochemical properties, have different functions. The functional significance of the vlG is discussed.
