Objectives: This study aims to investigate the anti-hypertensive effects of aqueous extract of and their underlying mechanism using a two-kidney one-clip (2K1C) model of reno-vascular hypertension in rats.

Methods: The reno-vascular hypertensive rats were treated with leaf extract (100 and 500 mg/kg; p.o.

This study aims to clarify the bioactive constituents responsible for the anti-dementia effects of Ocimum sanctum Linn. ethanolic extract (OS) using olfactory bulbectomized (OBX) mice, an animal model of dementia. The effects of OS or its extract further fractionated with n-hexane (OS-H), ethyl acetate (OS-E), and n-butanol (OS-B) on the spatial cognitive deficits of OBX mice were elucidated by the modified Y-maze tests.

Ethnopharmacological Relevance: Butea superba (BS) is a Thai medicinal plant that has been used as a folk medicine to improve physical and mental conditions and to prevent impaired sexual performance in middle-aged or elderly males. We have previously reported that this plant extract could improve cognitive deficits and depression-like behavior in olfactory bulbectomized mice, an animal model of dementia and depression.

Aim Of The Study: In this study we examined the effect of BS on depression-like behavior in mice subjected to unpredictable chronic mild stress (UCMS) to clarify the antidepressant-like activity of BS and the molecular mechanism underlying this effect.

Article Synopsis
  • The study explores how acetylcholine (ACh), elevated by tacrine (THA), helps protect hippocampal cells from long-lasting damage caused by NMDA, focusing on the VEGF signaling system.
  • The findings show that inhibiting protein kinase C (PKC) significantly reduces the protective effects of THA, while inhibiting JNK pathways has no effect, indicating a specific pathway involvement.
  • Acetylcholine counteracts NMDA-induced changes, such as increased HIF1α and decreased VEGF-A, affecting the expression of VEGF-A in astrocytes and VEGFR-2 in neurons, suggesting a paracrine signaling mechanism that supports neuron survival.

This study aimed to investigate a recuing role of cholinergic systems in the excitotoxicity-induced hippocampal cell damage. Organotypic hippocampal slice cultures (OHSCs) were prepared from 7-day-old mice and exposed to N-methyl-d-aspartate (NMDA) for 24h. After washing out the NMDA, OHSCs were incubated in medium containing test drugs for 0-6 days.
