[Electrolyte composition of the cerebrospinal fluid and neuromuscular excitability in epilepsy].

Clinical (Chvostek symptom and Trousseau-Bonsdorf test) and electromyographical investigations of the neuromuscular excitability were performed in patients with different forms of epilepsy. Ionized Ca, Na, K, Cl, and total Mg were measured in the cerebrospinal fluid (CSF). Seventy-five percent of the patients showed clinical and electromyographic signs of the tetanic syndrome.

[Electron histochemical and x-ray spectral study of the product of the reaction to calcium in the cerebral cortex and caudate nucleus of rats exposed to glypin].

Localization of the product of the reaction to calcium on the sections of the cortex and caudate nucleus of the rat brain was studied by electron histochemistry and x-ray spectral analysis during the exposure to toxic doses of the M-cholinolytic. The evidence obtained warrants a conclusion that in the early stage of poisoning there is a pronounced excitation of adrenergic neurotransmission associated with calcium redistribution in postsynaptic neurons.

[Electron microscopic and histochemical study of the localization of adenylate cylase and acetylcholinesterase in the synapses of the rat cerebral cortex and basal ganglia].

Synapses of the brain cortex and basal ganglia of the rat were studied by means of electron histochemical reactions to adenylate cyclase and acetylcholinesterase. Three types of synapses, viz. cholinergic, adrenergic and mixed, were identified.
