BR-16A is an herbal (non allopathic) medication used in India to enhance cognition. In experiment 1, 28 Wistar rats received either BR-16A (200 mg/kg/day) or vehicle alone for 3 weeks. During the third week, the rats were tested for learning in the Hebb Williams complex maze. BR-16A-treated rats showed significantly better learning than did controls. Experiment 2 was conducted identically excep...

Electroconvulsive shock (ECS) induces not only an antidepressant effect but also adverse effects such as amnesia. One potential mechanism underlying both the antidepressant and amnesia effect of ECS may involve the regulation of serotonin (5-hydroxytryptamine) 6 (5-HT6) receptor, but less is known about the effects of acute ECS on the changes in 5-HT6 receptor expression in the hippocampus. In ...

The influence of repeated administration of tianeptine, an atypical antidepressant, which was administered twice daily (10 mg/kg) for 14 days and zinc hydroaspartate, a compound exhibiting antidepressant-like activity, which was administered twice daily (65 mg/kg) for 14 days, and the effects of electroconvulsive shocks (ECS) delivered once daily for 10 days, were investigated ex vivo in rat hi...

A single electroconvulsive shock (ECS) or a sham ECS was administered to male 3-4-month-old Wistar rats 1, 2, and 4 h before training in an inhibitory avoidance test and in cued classical fear conditioning (measured by means of freezing time in a new environment). ECS impaired inhibitory avoidance at all times and, at 1 or 2 h before training, reduced freezing time before and after re-presentat...

Head trauma leading to concussion and electroconvulsive shock (ECS) in humans causes amnesia for events that occurred shortly before the injury (retrograde amnesia). The present experiment investigated the amnesic effect of lidocaine and ECS in 25 rats trained on a working memory version of the Morris water task. Each day, the escape platform was moved to a new location; learning was evidenced ...

OBJECTIVE The interaction between MK-801, a model of psychosis and KCl-induced depolarization or electroconvulsive shock (ECS), a therapeutic model of electroconvulsive therapy (ECT), was investigated in SH-SY5Y cells and the rat frontal cortex. METHODS SH-SY5Y cells were pretreated with 1 microM MK-801 for 15 min, followed by cotreatment with 100 mM KCl for 5 min. MK-801 was reintroduced aft...

BR-16A is an herbal (non-allopathic) medication used in India to enhance cognition. Sixty adult male Sprague Dawley rats received either BR-16A (200 mg/kg/day) or vehicle alone for 16 days. During the first 7 days, the rats were trained in a spatial memory task using the Hebb Williams complex maze. Once a day for the next 2 days, rats in BR-16A and control groups received either true or sham el...

The molecular mechanisms underlying the effects of electroconvulsive shock (ECS) therapy, a fast-acting and very effective antidepressant therapy, are poorly understood. Changes related to neuroplasticity, including enhanced adult hippocampal neurogenesis and neuronal arborization, are believed to play an important role in mediating the effects of ECS. Here we show a dynamic upregulation of the...

The effects of methohexitone and propanidid on the cardiovascular system of patients undergoing electroconvulsive therapy were evaluated on thirty-five patients. The anaesthetic and electroconvulsive therapy practice included intubation as a routine and pulmonary ventilation with 100 per cent oxygen between the administration of the shock and the onset of spontaneous respiration. The electrocar...

Vascular endothelial growth factor (VEGF) is a protein factor which has been found to play a significant role in both normal and pathological states. Its role as an angiogenic factor is well-established. More recently, VEGF has been shown to protect neurons from cell death both in vivo and in vitro. While VEGF's potential as a protective factor has been demonstrated in hypoxia-ischemia, in vitr...
