Effect of lignin-derived lignophenols on vascular oxidative stress and inflammation in streptozotocin-induced diabetic rats.

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
Lignophenols (LP) are the derivatives of native lignin, which is an abundant organic polymer in the plant kingdom. This study investigated whether LP can attenuate vascular oxidative stress and inflammation in streptozotocin (STZ)-induced diabetic rats. The diabetic rats induced by a single intravenous injection of STZ were randomly divided into two groups fed either 0 or 1.0% LP-containing diet. After 5 weeks of treatment, the superoxide (O(2)(-)) production, mRNA expression levels of nicotinamide adenine dinucleotide (phosphate) (NAD(P)H) oxidase subunits, monocyte chemoattractant protein-1 (MCP-1) and its receptor C-C chemokine receptor 2 (CCR2), and protein expression level of inducible nitric oxide synthase (iNOS) were examined in the aorta of vehicle-injected control and diabetic rats treated with or without LP. The increased O(2)(-) production and mRNA expression levels of NAD(P)H oxidase subunits Nox4 and p47phox were found to be significantly reduced in the aorta of diabetic rats treated with LP. The mRNA expression of MCP-1 and CCR2, and the protein expression of iNOS were found to be increased in the aorta of untreated diabetic rats, whereas these levels were significantly lower in the LP-treated group. These findings suggest that LP could attenuate vascular oxidative stress and/or inflammation via inhibition of NAD(P)H oxidase. This may lead to an improvement in the vascular impairment of diabetes.
