1 · What the graph read from it

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.

2 · The registry

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

aimThis study aims to determine mechanisms of action of the gasotransmitter hydrogen sulfide (H(2)S) on contractile activity in longitudinal muscle of rat ileum.

methodsIleal longitudinal muscle strips were prepared to measure isometric contractions. Effects of sodium hydrosulfide (NaHS), a donor of H(2)S, were evaluated on spontaneous contractile activity and after enhanced contractile activity with bethanechol. L-cysteine was evaluated as a potential endogenous donor of H(2)S. We evaluated involvement of extrinsic nerves, enteric nervous system, visceral afferent nerves, nitric oxide, and K(ATP)(+) channel and K(Ca)(+) channel activity on the action of H(2)S using non-adrenergic/non-cholinergic conditions, tetrodotoxin, capsaicin, L-N(G)-nitro arginine (L-NNA), glibenclamide, and apamin, respectively, as well as electrical field stimulation.

resultNaHS dose-dependently and reversibly inhibited spontaneous and bethanechol-stimulated contractile activity (p < 0.05). L-cysteine had no inhibitory effect. Non-adrenergic/non-cholinergic conditions, tetrodotoxin, capsaicin, L-NNA, glibenclamide, or apamin had no major effect on total contractile activity by NaHS, although both tetrodotoxin and apamin decreased the frequency of bethanechol-enhanced contractile activity (p < 0.05). We could not demonstrate H(2)S release by electrical field stimulation but did show that inhibition of cystathionine β synthase, an endogenous source of H(2)S, augmented the inhibitory effect of low-frequency electrical field stimulation.

conclusionH(2)S inhibits contractile activity of ileal longitudinal muscle dose-dependently but not through pathways mediated by the extrinsic or enteric nervous system, visceral afferent nerves, nitric oxide, K(ATP)(+) channels, or K(Ca)(+) channels.
