1. To test the hypothesis that protein kinase C (PKC) is involved in the inhibitory actions of lipoxin A4 (LXA4) on second messenger generation, we studied the effects of LXA4 on PKC in human neutrophils and on leukotriene B4 (LTB4)-stimulated inositol-1,4,5-trisphosphate (Ins(1,4,5)P3) generation. 2. LXA4, 1 microM, caused a fall in cytosolic PKC-dependent(More)
The sequestration of [3H]spiperone by lymphocytes was studied in preserved cells obtained from 22 schizophrenic subjects and 40 of their relatives, and the results were compared with those obtained from 25 healthy control subjects. Mean displaceable sequestration values, obtained from measurements made at a single radioligand concentration (1nM) which(More)
The nutritional status of 23 severely demented patients was compared with that of 23 similarly aged controls in the community. A 3-day weighed intake on all subjects showed lower mean intakes of energy, protein, ascorbic acid and nicotinic acid in the mean intakes of energy, protein, ascorbic acid and nicotinic acid in the patient group. This group had(More)
