[Neurons responsible for non-synaptic coordination of motor rhythms in CNS of Lymnaea].

Giant hyperpolarizing waves in the nitrergic neurons B2 controlling gut motility in Lymnaea are characteristic elements of transient coordination between the B2 rhythm and that of the buccal central pattern generator. Here, we identified a novel group of neurons that seems to be responsible for the occurrence of giant hyperpolarizing waves in the B2 neurons. Each of the paired buccal ganglia was found to contain two such neurons.

[The use of ketamine in cesarean section].

During cesarean section and basal nitrous oxide anesthesia ketamine was given to 31 parturients in an intravenous, drop fashion at a rate of 2 mg/kg/min concurrently with atropine, pipolphen, and droperidol premedication. The objective monitoring of anesthesia by using electroencephalography and blood adrenaline, noradrenaline, and cortisol levels showed that ketamine added to the complex of anesthetics provided a good analgesia and caused no drug-induced fetal depression.
