Differential actions of AlF4- and vanadate on canine trachealis muscle.

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
Fluoride (F-) a known stimulator of G-protein, has been reported to inhibit "P"-type ATPase activity in smooth muscles. On the other hand, vanadate, a strong "P"-type ATPase inhibitor, has been reported to stimulate G-protein in some cells. This study was designed to compare the contractile actions of fluoroaluminate (AlF4-) and vanadate and to clarify their mechanisms of actions by measuring changes in the amount of cyclic adenosine monophosphate (cAMP) and inositol phosphates. F- and vanadate induced strong contractions in canine trachealis muscle. The F(-)-induced contraction was potentiated by the addition of aluminum (Al3+, 20 microM) and inhibited by deferoxamine (200 microM), a heavy metal chelator. Ca2+ removal and 10 microM verapamil inhibited the contraction induced by AlF4- and vanadate. AlF4- and vanadate increased 45Ca influx in the absence and presence of verapamil. AlF4(-)-induced contractions were partially relaxed by isoproterenol (38.2 +/- 7.4%) in contrast with those induced by vanadate (72.1 +/- 5.3%), which could be explained by a decrease of tissue cAMP content by AlF4- in forskolin-pretreated tissues. Vanadate increased inositol phosphate accumulation as did AlF4-, although the magnitude of the increase was smaller than that produced by AlF4-. The increases of inositol phosphate content by both drugs were not affected after the pretreatment by pertussis toxin.(ABSTRACT TRUNCATED AT 250 WORDS)
