Membrane changes in rat erythrocyte ghosts on ghee feeding.

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
Alterations in membrane lipid composition is known to result in functional and structural changes in the membrane, and dietary lipids play an important role in this change. It was of interest to study the influence of ghee feeding to the rat on membrane structure and function. The activities of membrane bound enzymes Na+ K+ ATPase and Acetylcholinesterase were studied as an index of membrane changes. Male weanling rats were fed 2.5% fresh or thermally oxidized ghee in the diet for a period of 8 weeks. The control rats were fed groundnut oil. A decrease of 28% in the membrane fluidity of erythrocyte ghost membranes was observed in the oxidized ghee fed group at 37 degrees C, by fluorescence polarization measurements using 1,6-Diphenyl-1,3,5-hexatriene as a probe. The activities of Na+ K+ ATPase and Acetylcholinesterase showed an increase of 65 and 200% respectively after feeding oxidized ghee (2.5%). Also changes in Na+, K+ and ATP kinetics were observed in these rats. Increased membrane lipid peroxidation (80%) and C/PL ratio (11%) in the oxidized ghee fed group was observed. Marginal changes in the fatty acid composition were also seen. Further, an increase in the osmotic fragility of erythrocytes was observed in the oxidized ghee fed rats. It is inferred from these experiments that consumption of oxidized ghee with the diet affects the erythrocyte ghost membrane structure and function at 2.5% level, whereas consumption of fresh ghee has no effect on the erythrocyte membrane.
