huperzine a/ischemia

Huperzine A, a reversible and selective acetylcholinesterase (AChE) inhibitor, has been reported to display neuroprotective properties. The present study investigated the protective effects of huperzine A in a rat model of transient focal cerebral ischemia created by middle cerebral artery occlusion

The protective effects of huperzine A on transient global ischemia in gerbils were investigated. Five min of global ischemia in gerbils results in working memory impairments shown by increased escape latency in a water maze and reduced time spent in the target quadrant. These signs of dysfunction

BACKGROUND Nowadays, hepatic ischemia reperfusion (HI/R) injury is regarded as a serious concern in clinical practices. Huperzine A (HupA) is an alkaloid isolated from the Chinese folk medicine huperzia serrate, which has possessed diverse pharmacological actions. METHODS A mouse model of HI/R was

Hepatic ischemia reperfusion (HI/R) injury may occur during liver transplantation and remains a serious concern in clinical practice. Huperzine A (HupA), an alkaloid isolated from the Chinese traditional medicine Huperzia serrata, has been demonstrated to possess anti‑oxidative and anti‑apoptotic

This study is to investigate the effects of huperzine A on memory deficits, neuronal damage and neurotrophic factors production after transient cerebral ischemia and reperfusion in mice, as well as the potential downstream signaling pathway. Bilateral common carotid occlusion (BCCAo) combined with

The protective effects of huperzine A, a novel acetylcholinesterase inhibitor, on hypoxic-ischemic (HI) brain injury were investigated in neonatal rats. A unilateral HI brain injury was produced by the ligation of left common carotid artery followed by 1 h hypoxia with 7.7% oxygen in 7-day-old rat

We recently reported that the expression of the synaptic form of acetylcholinesterase (AChE) is induced during apoptosis in various cell types in vitro. Here, we provide evidence to confirm that AChE is expressed during ischemia-reperfusion (I/R)-induced apoptosis in vivo. Renal I/R is a major cause

BACKGROUND Spinal cord injury is nowadays still a challenging disease, and a treatment option aimed at the primary site of injury does not currently exist. Therefore, the management of acute spinal cord injury has recently focused on the reasons behind the aggravation of the initial insult through

The effects of (-)-huperzine A, a promising therapeutic agent for Alzheimer's disease, on learning behavior and on alterations of the cholinergic system, the oxygen free radicals and energy metabolites induced by permanent bilateral ligation of the common carotid arteries were investigated in rats.

BACKGROUND Alzheimer's disease (AD) has become a major public health problem around the world due to its increasing prevalence, long duration, caregiver burden, and high financial cost of care. The degeneration of acetylcholine-containing neurons in the basal forebrain has been implicated in the

Mitochondrial dysfunction has been proved to contribute to ischemia-induced brain damage. In this study, which used a rat middle cerebral artery occlusion (MCAO) model, the protective effects of huperzine A (HupA) against mitochondrial dysfunction and brain damage were investigated. MCAO for 45 min

Post-stroke depression (PSD) is the most common mood disorder following a stroke, and is also the main factor limiting recovery and rehabilitation in stroke patients. The present study was aimed to investigate whether Huperzine A (HupA) has antidepressant-like activity in a rat model of PSD, which

Huperzine A (HUP-A), first isolated from the Chinese club moss Huperzia serrata, is a potent, reversible and selective inhibitor of acetylcholinesterase (AChE) over butyrylcholinesterase (BChE) (Life Sci. 54: 991-997). Because HUP-A has been shown to penetrate the blood-brain barrier, is more stable

Huperzine A (HupA), isolated from Chinese herb Huperzia serrata, is a potent, highly specific and reversible inhibitor of acetylcholinesterase. It has been found to reverse or attenuate cognitive deficits in a broad range of animal models. Clinical trials in China have demonstrated that HupA

Huperzine A (HupA), a novel alkaloid isolated from the Chinese herb Huperzia serrata, is a potent, highly specific and reversible inhibitor of acetylcholinesterase(AChE). Compared with tacrine, donepezil, and rivastigmine, HupA has better penetration through the blood-brain barrier, higher oral
