Anandamide transporter-mediated regulation of the micturition reflex in urethane-anesthetized 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
purposeThe aim of this study was to investigate the effects of an anandamide transporter inhibitor that can increase endogenous anandamide concentration on the micturition reflex in urethane-anesthetized rats.
methodsContinuous cystometrograms were performed in female Sprague-Dawley rats under urethane anesthesia. After stable micturition cycles were established, VDM11 (1, 3 and 10 mg/kg), an anandamide membrane transporter inhibitor, was administered intravenously to evaluate changes in bladder activity. In experiments examining the effects of cannabinoid (CB) receptor antagonists, VDM11 (10 mg/kg) was injected intravenously when the first bladder contraction was observed after intravenous administration of AM251, a CB1 receptor antagonist (3 mg/kg), or AM630, a CB2 receptor antagonist (3 mg/kg).
resultsIntravenous administration of VDM11 increased intercontraction intervals and threshold pressure at doses of 3 mg/kg or higher in dose-dependent fashion. When AM251 was administered one voiding cycle before VDM11 administration, the increases in intercontraction intervals and threshold pressure induced by VDM11 administration alone were not seen. In contrast, when AM630 was administered before VDM11 administration, increases in intercontraction intervals and threshold pressure were observed, as they were after VDM11 alone.
conclusionThese results suggest that anandamide, an endogenous CB ligand, can modulate the micturition reflex and that anandamide transporters play an important role in this modulation. In urethane-anesthetized rats, inhibition of the uptake of anandamide can inhibit the micturition reflex and these inhibitory effects of VDM11 are at least in part mediated by the CB1 receptor.
