Cerebroprotection by angiotensin-(1-7) in endothelin-1-induced ischaemic stroke.

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
Activation of angiotensin-converting enzyme 2 (ACE2), production of angiotensin-(1-7) [Ang-(1-7)] and stimulation of the Ang-(1-7) receptor Mas exert beneficial actions in various peripheral cardiovascular diseases, largely through opposition of the deleterious effects of angiotensin II via its type 1 receptor. Here we considered the possibility that Ang-(1-7) may exert beneficial effects against CNS damage and neurological deficits produced by cerebral ischaemic stroke. We determined the effects of central administration of Ang-(1-7) or pharmacological activation of ACE2 on the cerebral damage and behavioural deficits elicited by endothelin-1 (ET-1)-induced middle cerebral artery occlusion (MCAO), a model of cerebral ischaemia. The results of the present study demonstrated that intracerebroventricular infusion of either Ang-(1-7) or an ACE2 activator, diminazine aceturate (DIZE), prior to and following ET-1-induced MCAO significantly attenuated the cerebral infarct size and neurological deficits measured 72 h after the insult. These beneficial actions of Ang-(1-7) and DIZE were reversed by co-intracerebroventricular administration of the Mas receptor inhibitor, A-779. Neither the Ang-(1-7) nor the DIZE treatments altered the reduction in cerebral blood flow elicited by ET-1. Lastly, intracerebroventricular administration of Ang-(1-7) significantly reduced the increase in inducible nitric oxide synthase mRNA expression within the cerebral infarct that occurs following ET-1-induced MCAO. This is the first demonstration of cerebroprotective properties of the ACE2-Ang-(1-7)-Mas axis during ischaemic stroke, and suggests that the mechanism of the Ang-(1-7) protective action includes blunting of inducible nitric oxide synthase expression.
