In vitro effects of cAMP-elevating agents and glucocorticoid either alone or in combination on the production of nitric oxide, interleukin-12 and interleukin-10 in IFN-gamma- and LPS-activated mouse peritoneal macrophages.

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 effects of cAMP-elevating agents, N6-2'-O-dibutyryl cAMP (Bu2cAMP), and glucocorticoid (dexamethasone) on the production of inflammatory mediators--nitric oxide and interleukin-12 (IL-12) and anti-inflammatory mediator interleukin-10 (IL-10) were demonstrated in murine peritoneal macrophages. Inducible nitric oxide synthase (iNOS) and iNOS mRNA were detected by northern blot and western blot, respectively. The cAMP elevating agents Bu2cAMP and prostaglandin E2 each alone did not show any effect on NO production but along with IFN-gamma and lipolysaccharide (LPS) they slightly enhanced NO production. Dexamethasone inhibited NO production in IFN-gamma- and LPS-treated cells; cAMP elevating agents interfered with the NO production inhibited by dexamethasone. Inhibition was revealed at the mRNA level as well as at protein level. Bu2cAMP or dexamethasone either alone or synergistically inhibited IL-12 production; Bu2cAMP interfered with dexamethasone-mediated inhibition of IL-10 production in IFN-gamma- and LPS-treated macrophages. The use of glucocorticoids along with cAMP elevating agents was beneficial in lowering the level of inflammatory mediator IL-12 and producing high levels of the anti-inflammatory mediator IL-10 active in cell protection. On the other hand, interference of Bu2cAMP with dexamethasone-mediated NO inhibition may have adverse effect. Therefore, adverse effects due to cAMP-mediated interference (inhibition) with NO synthesis may occur in many inflammatory diseases during combined drug therapy by glucocorticoids and cAMP elevating agents.
