Immunohistochemistry of the locust central nervous system with antibody to choline acetyltransferase (ChAT) purified from the same species shows: first, there are relatively few immunoreactive cell bodies in the CNS; and second, sensory neuropiles, such as the ventral association centre and the ventral VAC (vVAC), the anterior ring tract, the tritocerebrum and the antennal lobe, are immunoreactive. That ChAT is contained in sensory neurones is suggested by immunoreactivity found in peripheral neurone cell bodies. These results indicate that acetylcholine serves primarily as a sensory transmitter in the locust.

Immunocytochemistry of the locust central nervous system shows that most segmental nerves, in particular those of the legs, contain afferent fibres that react with antibody to 5-hydroxytryptamine (5-HT). Adsorption controls indicate that the antigen is 5-HT or a closely related compound. This is supported by the finding of significant amounts of 5-HT in leg nerves using reverse phase high-performance liquid chromatography (HPLC) and electrochemical detection.

Providing long-term care in acute care beds--the swing-bed concept--fills a community health care need and helps the small hospital financially. But more than the status of the bed changes as medical and nursing staffs must adjust their daily schedules and attitudes. Day-to-day problems encountered by the hospital staff are detailed, as well as some recommendations for the future.

Restless legs, anxiety and caffeinism.

J Clin Psychiatry

September 1978

This clinical study of 62 patients with restless legs syndrome and associated anxious-depressed and other clinical states seems to indicate that caffeine is the major etiological factor in the causation of the restless legs syndrome. Anxiety, while modifying the subjective experience of the dysphoric sensation of restless legs, is not a causative factor. Caffeine is responsible for the increased nervous system arousal as well as for the direct peripheral contractile effect on the striated muscle.

Subclinical extrapyramidal symptoms caused by phenothiazine or butyrophenone derivatives can become manifest during and shortly after the consumption of alcohol. Alcohol appears to lower the threshold of resistance to neurotoxic side effects of previously established neuroleptic drugs. Abstinence from alcohol should be routine advice during neuroleptic psychopharmacotherapy.

The effect of tyramine infusion or exercise on catecholamine concentration and dopamine-beta-hydroxylase activity in plasma of normal volunteers has been studied. Whereas the increase in plasma catecholamine concentrations by tyramine infusion was not changed 90 min after oral application of a single dose of beta-adrenoceptor blocking drugs (penbutolol, practolol, I.C.
