Effects of leucine-enkephalin on potassium currents in neurons in the rat respiratory center in vitro.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Experiments to identify the neuronal mechanisms underlying the respiratory activity of the opioid peptide leucine-enkephalin were performed on transverse slices of the rat brainstem in voltage-clamped conditions; studies addressed the effects of this peptide (10 nM-1 microM) on the potassium A current and the inward potassium current of neurons in two areas of the respiratory center: the ventrolateral area of the solitary tract nucleus and the pre-Bötzinger complex. The parameters of the A current assessed in all respiratory center neurons studied showed no change in the presence of leucine-enkephalin. At the same time, leucine-enkephalin produced reversible increases in the amplitude of the inward potassium current. These results provide evidence that the inhibitory effect of leucine-enkephalin at the level of respiratory center neurons is at least in part explained by its stimulatory action on the inward potassium current but is not associated with modulation of the potassium A current.
