Effect of Aeromonas hydrophila enterotoxins on function of mouse phagocytes.
Article in Digestive diseases and sciences, 1992. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Two enterotoxins produced by Aeromonas hydrophila isolate SSU have been characterized in this laboratory. One is a cholera toxin cross-reactive cytolytic enterotoxin (CTC toxin) and the other is a non-cholera toxin cross-reactive cytotonic enterotoxin (non-CTC toxin). The two enterotoxins are capable of causing fluid accumulation in animal models; however, only the CTC toxin is lethal to mice and expresses hemolytic as well as cytotoxic activities. In this study, we have investigated the effects of these two toxins on mouse phagocytes. Four hours after intraperitoneal injection of a sublethal dose (460 micrograms/kg of body weight) of CTC toxin, the chemiluminescence (CL) response of phagocytes in mouse blood was depressed significantly when compared with that observed for controls (intraperitoneal injection of only Hanks' balance salt solution, non-CTC toxin or before treatment with CTC toxin). When fresh whole blood was incubated with various concentrations (2.3, 11.5, 23, 230, 2300 ng/ml) of CTC toxin for 1.5 hr at 37 degrees C, the CL response of blood phagocytes was reduced strikingly in a dose-dependent fashion; however, non-CTC toxin did not inhibit the CL response. The inhibitory effect induced by CTC toxin of the phagocytic function not only was abolished completely, but phagocytosis was enhanced in the presence of interferon-gamma (IFN-gamma). In addition, IFN-gamma alone induced the largest enhancement of the CL response in mouse phagocytes. These results demonstrated that CTC toxin inhibits the phagocytic ability of phagocytes either in vivo or in vitro and that IFN-gamma pretreatment can overcome this toxic effect.(ABSTRACT TRUNCATED AT 250 WORDS)
