In vivo assessment of the effects of ginsenoside Rb1 on intimal hyperplasia in ApoE knockout mice.

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
objectiveThis study investigated the effects of ginsenoside Rb1 (Rb1) on injury-induced intimal hyperplasia in ApoE knock out (ApoE -/-) mice. We also examined the value of an ultrasound micro-image system in dynamic monitoring of lumen diameter and flow velocity.
methodsAfter guide wire injury of the distal left common carotid artery (CCA), ApoE-/- mice were treated with intraperitoneal infusion of normal saline (NS), homocysteine (Hcy), ginsenoside Rb1 (Rb1), or Hcy+Rb1 for 4 wk. Bilateral CCA luminal diameters and flow velocities were measured with an ultrasound micro-image system before surgery and weekly afterwards. Following the final ultrasound, CCAs were harvested and analyzed for intima-medium thickness ratios.
resultsProgressive reduction in luminal diameters and increase in flow velocity of the injured left distal CCA segment were observed using ultrasound micro-imaging system in all groups compared with the relatively stable left proximal CCA and right CCA. The NS and Hcy groups had significantly higher degree of diameter reduction compared with the Rb1 and Rb1+Hcy groups. The ultrasound findings were consistent with histology analyses at 4 wk post-op.
conclusionsThe study suggested that Rb1 attenuated the effects of Hcy on injured carotid arteries of ApoE -/- mice. The study also showed that ultrasound micro-image system was a reliable tool in monitoring luminal reduction after injury in a murine model. This study establishes a fundamental step of in vivo monitoring of the therapeutic effects of agents in a murine model without sacrificing the animals.
