vincamine/atrophy

The neuropsychiatric symptoms of old patients with disturbed cerebral metabolism or blood flow mostly lead to great individual difficulties and make those patients difficult to handle: in the family as well as in hospital such patients develop alienation, isolation and therefore adaptation to a

Vinpocetine, a derivative of vincamine, widely used in the clinical pharmacotherapy of cerebral circulatory diseases, inhibits retrograde axoplasmic transport of nerve growth factor (NGF) in the peripheral nerve, resulting in transganglionic degenerative atrophy (TDA) in the related ipsilateral

Certain drugs can induce ventricular tachycardia (VT) by creating reentry, ventricular after potentials or exaggerating the slope of phase 4. These may or may not be symptomatic, sustained or non-sustained and have variable ECG appearances: monomorphic or polymorphic, bidirectional, torsades de

Vinpocetine, a derivate of vincamine, is widely used in the clinical pharmacotherapy of cerebral circulatory diseases. Herewith we report on a novel effect of vinpocetine: inhibition of retrograde axoplasmic transport of nerve growth factor (NGF) in the peripheral nerve. Blockade of retrograde

Blockade of retrograde transport of nerve growth factor (NGF) in a peripheral sensory nerve is known to induce transganglionic degenerative atrophy (TDA) of central sensory terminals in the upper dorsal horn of the related, ipsilateral segments(s) of the spinal cord. The ensuing temporary blockade

Severe hypoglycemia with isoelectric EEG induced extensive deterioration of the energy state and gross alteration of amino acid contents on the rat cerebral and cerebellar cortex. During recovery, tissue glucose concentration returned to normal, while both lactate and pyruvate concentrations

On rat cerebral and cerebellar cortex, severe hypoglycemia with isoelectric EEG induced extensive deterioration of the energy state and gross alteration of amino acid contents. During recovery, tissue glucose concentration returned to normal, while the rate of glycogen synthesis was slow, both

Manganese (Mn) is required for many essential biological processes as well as in the development and functioning of the brain. Extensive accumulation of Mn in the brain may cause central nervous system dysfunction known as manganism, a motor disorder associated with cognitive and neuropsychiatric
