Continuous fluorometric measurement of intracellular pH and Ca2+ in perfused salivary gland and pancreas.
Article in Pflugers Archiv : European journal of physiology, 1994. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Intracellular pH (pHi) has been measured in intact, perfused rat mandibular salivary glands loaded with the fluorescent pH indicator BCECF [2',7'-bis(2-carboxyethyl)-5(6)- carboxyfluorescein]. Glands mounted in the cuvette of a conventional bench-top spectro-fluorometer were perfused for 5 min with the acetoxymethyl ester of BCECF and fluorescence was measured ratiometrically at 6-s intervals. The mean value of pHi in glands perfused with a HCO3(-)-free, N-2-hydroxyethylpiperazine-N'-2- ethanesulphonic acid (HEPES)-buffered solution at 37 degrees C was 7.36 +/- 0.01 (n = 52) which is comparable with values obtained by 31P nuclear magnetic resonance (NMR) spectroscopy. NMR data confirmed that the BCECF loading period was accompanied by a transient acidification of the cells, but there was no significant change in the content of the major phosphorus metabolites. Changes in pHi in response to NH4Cl pulses and acetylcholine stimulation were comparable with results reported previously for isolated acini. Additional, preliminary experiments show that the method can also be used to monitor intracellular Ca2+ (using fura-2) in perfused salivary glands, and can be adapted for studies of the isolated, perfused pancreas.
