Effect of BRL-35135 on LTB4-induced guinea pig eosinophil chemotaxis.
Article in Agents and actions, 1992. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 effect of an atypical beta-adrenoceptor agonist, BRL-35135 on leukotriene B4-induced-guinea pig eosinophil chemotaxis was studied. BRL-35135 and SC-41930 (leukotriene B4-antagonist) inhibited the chemotaxis in a concentration-dependent manner (IC50 = 9.0 x 10(-6) and 2.6 x 10(-7) M, respectively). However, isoproterenol, fenoterol and another atypical beta-agonist, BRL-37344 had no effects. The inhibitory effect of BRL-35135 was not affected by (+/-)-propranolol (10(-4) M). In contrast, the nonselective beta-adrenoceptor antagonist, (-)-alprenolol (10(-4) M) dextrally shifted the inhibitory curve of BRL-35135. The response to BRL-35135 was antagonized in a competitive manner by (-)-alprenolol, with the slope of the Schild plot close to unity, and a pA2 value of 5.62. These findings suggest that guinea pig eosinophils possess an "atypical receptor", which differs from either beta 1-, beta 2- or atypical beta-adrenoceptor on guinea pig ileum, and through which eosinophil chemotaxis can be modulated by BRL-35135.
