Plain-language summary

This study investigates the beneficial role of lisinopril, an angiotensin converting enzyme inhibitor (ACEI) and telmisartan, an angiotensin receptor blocker (ARB), in intracerebroventricular (i.c.v.) streptozotocin (STZ) induced dementia of Alzheimer's disease (AD) type in mice. This study also aimed to explore the role of PPAR-γ in lisinopril and telmisartan mediated effects in i.c.v. STZ mice. Donepezil served as the positive control in the study. Mice underwent i.c.v. injection of STZ. The Morris water maze (MWM) test was employed for assessment of learning and memory. Various biochemical estimations, namely brain acetylcholinesterase (AChE) activity, myeloperoxidase (MPO) activity, nitrite/nitrate and thiobarbituric acid reactive species (TBARS) levels and reduced glutathione (GSH) levels, were also performed. The study showed that i.c.v. STZ significantly impaired learning and memory of the animals along with a significant enhancement in brain AChE, MPO, TBARS, nitrite/nitrate levels and reduction in brain GSH levels. Treatments of lisinopril/telmisartan/donepezil significantly attenuated STZ induced behavioral and biochemical changes. Pre-treatment with bisphenol-A-diglycidyl ether (BADGE), a selective PPAR-γ antagonist, significantly abolished the beneficial effect of lisinopril/telmisartan in i.c.v. STZ treated animals. The results of this investigation document a potential role of PPAR-γ in the beneficial effects of lisinopril and telmisartan in i.c.v. STZ dementia of AD type.

How to read this study

Design: our record does not state a study design, so check the methods section of the original before weighing the result.
Size: the record gives no participant count. Look for one in the original before trusting a pattern.
Effect: the record gives no effect size, so the summary above cannot say how large any difference was.

What the evidence grade means here

This page is graded low. alzhub.org assigns the grade automatically from keywords in the abstract, not from reading the paper. Low means the abstract matched neither pattern. It is the default label, and it does not mean the work is poor; many sound lab and imaging papers land here. It can add at most 5 of the 100 points in the study score, and it is a label about design, not a verdict on whether the findings are true.

Key findings

STZ significantly impaired learning and memory of the animals along with a significant enhancement in brain AChE, MPO, TBARS, nitrite/nitrate levels and reduction in brain GSH levels.
Treatments of lisinopril/telmisartan/donepezil significantly attenuated STZ induced behavioral and biochemical changes.
Pre-treatment with bisphenol-A-diglycidyl ether (BADGE), a selective PPAR-γ antagonist, significantly abolished the beneficial effect of lisinopril/telmisartan in i.c.v.
The results of this investigation document a potential role of PPAR-γ in the beneficial effects of lisinopril and telmisartan in i.c.v.

How this study scored 36/100

Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomized / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multicenter collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
