Amino acid release from biopsy samples of temporal neocortex from patients with Alzheimer's disease.

Abstract:

:Tissue prisms prepared from neurosurgical samples of temporal neocortex of Alzheimer and control patients, upon depolarization preferentially released aspartate, glutamate and gamma-aminobutyrate (GABA). The Alzheimer and control samples did not significantly differ in the pattern of amino acid release, although acetylcholine synthesis by the Alzheimer tissue prisms was greatly reduced. There was no correlation between the efflux of any amino and acetylcholine synthesis. These observations suggest that in Alzheimer's disease there are no major changes in the extracellular concentrations of these putative amino acid transmitters.

  • Naloxone stimulates comparable release of luteinizing hormone-releasing hormone from tissue fragments from ovariectomized, estrogen-treated young and middle-aged female rats.

    abstract::Endogenous opioids play a role in the regulation of LH-RH neurosecretion throughout the estrous cycle and during the preovulatory LH surge on proestrus. Experimental evidence suggests that opioid influence may be altered with age, and it has been hypothesized that these alterations may contribute to the loss of regula...
