Inhibition of phospholipase A2 activities and some inflammatory responses by the marine product ircinin.
Article in Naunyn-Schmiedeberg's archives of pharmacology, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
The marine product ircinin has been tested for its effects on secretory and cytosolic phospholipase A2 (PLA2) activities in vitro as well as for inhibition of cellular functions in human neutrophils and inflammatory responses in mice. Ircinin inhibited Naja naja venom, human synovial recombinant, bee venom and zymosan-injected rat air pouch PLA2 with IC50 values in the microM range, similar to those of the known inhibitor scalaradial. On the other hand, ircinin was less active on cytosolic PLA2 from human monocytes and decreased potently the release of LTB4 in human neutrophils. This marine product affected weakly human neutrophil functions like superoxide generation and degranulation. In the zymosan-injected rat air pouch ircinin inhibited in vivo the activity of PLA2 present in exudates and reduced dose-dependently myeloperoxidase levels, whereas cell migration was inhibited only at the highest dose tested. This compound exerted a potent anti-oedematous effect after topical application in the mouse ear oedema test. Ircinin is a new inhibitor of PLA2 activity and our results suggest a potential role for this marine product as an inhibitor of inflammatory processes.
