Using a repeated acquisition procedure in a 3-panel runway apparatus, the effect of WEB 1881 FU on impairment of working memory produced either by scopolamine or by cerebral ischemia was investigated in rats and compared with those of aniracetam and Ca hopantenate. Intraperitoneal injection of

Using a repeated acquisition procedure in a three-panel runway apparatus, the effects of minaprine on the impairment of working memory produced by scopolamine, ethylcholine aziridinium ion (AF64A) or cerebral ischemia were investigated in rats. Minaprine (3.2-32 mg/kg IP) as well as idebenone
Effects of bifemelane hydrochloride (MCI-2016) on acetylcholine (ACh) level in the cerebral cortex and hippocampus of rats and Mongolian gerbils were examined. In normal rats, MCI-2016 (30 mg/kg, i.p.) slightly increased ACh content in the cerebral cortex. Scopolamine (1 mg/kg, i.p.) or hypoxia (95%
A repeated acquisition procedure in a 3-panel runway apparatus was used to investigate the effects to S-adenosyl-L-methionine (SAM) on impairment of working memory produced either by cerebral ischemia or by scopolamine in rats. Cerebral ischemia (2-10 min) produced duration-dependent increases in
Fasted Wistar rats were given a mild level of traumatic brain injury (TBI) and then subjected to 6 min of transient forebrain ischemia 24 h posttrauma. One group was given simultaneous 1 mg/kg scopolamine and 4 mg/kg phencyclidine intraperitoneally (IP) 15 min before trauma and another group an
The neurodegeneration in the CA1 subfield of hippocampus exhibited a dorsal-ventral gradient of susceptibility in global ischemia (82% dorsoseptally and only 16% ventrotemporally). Scopolamine (SCOP) did not improve the neuronal damage caused by the global ischemic challenge in rats and did not
The purpose of these studies were threefold. Firstly, to further characterize the effect of perforant path transection on a test of short-term memory: delayed matching (or nonmatching)-to-position [D(N)MTP]. Secondly, to evaluate the effect of a transient cerebral ischaemia in the same task. Both
The objective of this study was to investigate the protective effects of scopolamine and penehyclidine hydrochloride on acute cerebral ischemia-reperfusion injury after cardiopulmonary resuscitation, and the effect on cytokine levels. Eighty patients with cardiac arrest admitted to our hospital from
Global cerebral ischemia/reperfusion (GCI/R) injury encompasses complex pathophysiological sequalae, inducing loss of hippocampal neurons and behavioural deficits. Progressive neuronal death and memory dysfunctions culminate from several different mechanisms like oxidative stress, excitotoxicity,
Experimental and clinical evidence documents the beneficial effects of blocking sympathetic activity and modulating heart rate to reduce risk for lethal events in ischemic heart disease. Beside beta-adrenergic receptor blockade, vagal activation is a meaningful approach but not yet easily

The effect of Ginkgo biloba extract (GbE) on cerebral ischemia induced by 10-min bilateral occlusion of the carotid arteries in mice was studied. Severe impairment of memory was apparent when the passive avoidance test was carried out 48 hr after bilaterally induced ischemia. When GbE at doses of 50

Ingia / Ingia
The protective effect of vinconate, a vinca alkaloid derivative, on ischemia-induced neuronal damage was investigated using a model of rat forebrain ischemia caused by occlusion of four vessels. Hippocampal cell loss was observed histologically and neurochemically 5 days after 10 min of ischemia.

Do increases in markers of vagal activity imply protection from sudden death? The case of scopolamine.

Ingia / Ingia
BACKGROUND Low-dose scopolamine increases heart rate variability (HRV) in patients with a prior myocardial infarction (MI). This observation, combined with the evidence that elevated cardiac vagal activity during acute myocardial ischemia is antifibrillatory, has generated the hypothesis that
The effect of a standard preoperative medication combination, morphine and scopolamine, on arterial oxyhemoglobin saturation was measured continuously in 29 patients scheduled for elective coronary artery bypass grafting procedures. On the morning of operation, both before and after administration
