Pharmacological profiling of neuropeptides on rabbit vaginal wall and vaginal artery smooth muscle in vitro.
Article in British journal of pharmacology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
background and purposeHypothalamic neuropeptides centrally modulate sexual arousal. However, the role of neuropeptides in peripheral arousal has been ignored. Vascular and non-vascular smooth muscle relaxation in the vagina is important for female sexual arousal. To date, in vitro studies have focused on vaginal strips with no studies on vaginal arteries. The aim of this study was to compare the effects of sexual hypothalamic neuropeptides on rabbit vaginal wall strips and arteries. EXPERIMENTAL APPROACH: Tissue bath and wire myography techniques were used to measure isometric tension from strips and arteries, respectively. KEY
resultsPituitary adenylate cyclase-activating polypeptide (PACAP) and vasoactive intestinal peptide (VIP) relaxed both preparations, effects that were only antagonized by the VIP/PACAP antagonist VIP6-28 (10 nM) and the PAC(1) antagonist PACAP 6-38 (1 microM). The melanocortin agonist alpha-melanocortin-stimulating hormone (1 microM), but not bremelanotide (1 microM), also relaxed both preparations. Oxytocin and vasopressin contracted vaginal preparations, which could be antagonized by the V(1A) antagonist SR 49059. Neuropeptide Y (NPY) and the NPY Y(1) agonist Leu(31), Pro(34) NPY only contracted arteries, which was antagonized by the NPY Y(1) receptor antagonist BIBP 3226. Melanin-concentrating hormone (MCH; 1 microM) contracted arteries. CONCLUSION AND IMPLICATIONS: Hypothalamic neuropeptides can exert contractile and relaxant effects on vaginal strips and arteries. NPY Y(1), V(1A), MCH(1) antagonists as well as VIP/PAC(1) agonists may have therapeutic potential in both central and peripheral female sexual arousal. Differences in effect of neuropeptides between preparations raise the question of which preparation is important for female sexual arousal.
