usually centres on improving dopaminergic func tion in the nigro-striatal pathways. Levo-dopa and selegiline increase the amount of synaptic dopamine available; apomorphine, bromocriptlne and pergolide are agonists at dopamine receptors. Symptoms may also be improved by redressing the balance of dopaminergic and cholinergic activity. Benzhexol, procyclidine(More)
Tardive dyskinesia (TD),literally meaning a late occurring, abnormal movement disorder, was first described by Schonecker in 1957, about five years after the discovery of chlorpromazine (cited in Kane, 1992).

To determine the effect of resuscitation with hypertonic saline on extravascular lung water, seven adult sheep were endotracheally intubated; mean arterial pressure (MAP), pulmonary artery pressure (PAP), pulmonary capillary wedge pressure (PCWP), and central venous pressure (CVP) were monitored. A 5-French, thermistor-tipped catheter was used to measure(More)
The alcohol withdrawal syndrome is charac terised by symptoms such as anxiety, insomnia, anorexia, nausea, tremor, sweating and distur bances in coordination.
