Effects of atrial natriuretic factor, nitroprusside and acetylcholine on cGMP immunostaining in the isolated perfused rat kidney.

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
In the present study the localization of the cGMP production in response to the vasodilators acetylcholine (ACh) and sodium nitroprusside (SNP) and to atrial natriuretic factor (ANF) was studied in the isolated perfused rat kidney using cGMP immunocytochemistry. After ACh (0.3 microM) infusion increased cGMP immunoreactivity was found in kidney interlobar and segmental arteries and in glomeruli. SNP (1 microM) and ANF (0.01 microM) elevated cGMP staining in the same elements of the kidney as ACh. In the glomeruli ACh and SNP stimulated cGMP production in mesangial cells whereas ANF stimulated cGMP production in mesangial cells whereas ANF stimulated cGMP production in epithelial cells (podocytes). However, SNP at higher doses (10 microM) stimulated cGMP production not only in glomeruli, but also in interstitial cells throughout the cortex. In addition SNP and ANF increased cGMP production in the medulla.
