    Notes:
    Two psychiatric patient subgroups, defined on the basis of an extremely brief or an extremely prolonged electroencephalogram (EEG) response to cold pressor stimulation, also differ with regard to several aspects of autonomic response. The patients showing only a brief EEG desynchronization, with recovery during stimulation, also show a relatively brief autonomic response with recovery beginning during stimulation. They are specifically characterized by elevated levels of skin conductance throughout the measurement period. On the other hand, patients with prolonged EEG response show more prolonged autonomic response and are distinguished as a group by high heart rate levels. Clinical comparisons disclosed no diagnostic correlations. The rapid EEG and visceral recovery observed is discussed in terms of recently described neurophysiological mechanisms of homeostasis.

    Notes:
    Summary In 10 patients with Paget's disease of bone and 2 patients with osteoporosis, we studied the effects of hypocalcemia and hypophosphatemia induced by disodium-(3-amino-1-hydroxypropylidene)-1,-bisphosphonate (APD) treatment on the serum concentration of PTH and 1,25-dihydroxyvitamin D [1,25(OH)2D3] and on calcium absorption and balance. The fall in serum calcium and phosphate was associated with a rise in the serum concentration of PTH and 1,25(OH)2D3, coupled with increases in net calcium absorption and calcium balance. The concentration of 1,25(OH)2D3 was significantly related (P〈0.001) to the serum calcium (r=0.66), the serum phosphate (r=0.78), and the serum PTH (r=0.71), confirming the interrelated control of these parameters on 1,25(OH)2D3 production. Moreover, the rise in 1,25(OH)2D3 caused an appropriate rise in calcium absorption (r=0.74) and calcium balance (r=0.86), showing that this vitamin D metabolite contributes as a hormone to calcium homeostasis.

    Notes:
    Summary A simple, reproducible method for the biological synthesis of tritiated 24,25-dihydroxycholecalciferol, 25,26-dihydroxycholecalciferol and 1,25-dihydroxycholecalciferol is described. Kidney homogenates from both vitamin D deficient and replete chicks were usedin vitro to generate these dihydroxylated metabolites using 25 (23,24-3H) hydroxycholecalciferol as the substrate. Tritiated products were purified by Sephadex LH 20 chromatography followed by high-performance liquid chromatography; the identity of each metabolite was established by chromatography with authentic crystalline preparations.
