    Effect of Ca++ and GABA on oxidation of glutamate and glutamine by rat brain synaptosomes (1978)
    Springer
    Bulletin of experimental biology and medicine 86 (1978), S. 1158-1160 
    Details
    ISSN: 1573-8221
    Keywords: synaptosomes ; oxidation ; glutamine ; glutamate ; γ-aminobutyric acid
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Abstract Experiments in vitro showed that the addition of Ca++ inhibits respiration of rat brain synaptosomes in the presence of glutamate and glutamine. The addition of GABA potentiates the inhibitory effect of Ca++ on the oxidation of glutamine but not of glutamate. GABA itself has no effect on the oxidation of either glutamate or glutamine.

    Peroxidative oxidation of lipids in slices of olfactory cortex of the rat brain during long-term potentiation (1996)
    Springer
    Neuroscience and behavioral physiology 26 (1996), S. 23-26 
    Details
    ISSN: 1573-899X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Abstract The content of the products of the peroxidative oxidation of lipids (POL) in slices of olfactory cortex of the rat brain during long-term potentiation was investigated. The phasic character of the changes in the level of POL as a function of the duration of potentiation was demonstrated. The initial stages of potentiation (5 min) is characterized by an increase in POL; the stationary phase (15 min) is accompanied by inhibition of free-radical oxidation of lipids; the concluding phase of long-term potentiation (30 min) leads to the normalization of POL. The dynamics of the change in POL reflect the adaptive character of the development of potentiation in the slices.

    Number of correlates of membrane metabolism and long-term potentiation in rat brain slices (1997)
    Springer
    Neuroscience and behavioral physiology 27 (1997), S. 221-224 
    Details
    ISSN: 1573-899X
    Keywords: Rat brain slice ; long-term potentiation ; 45Ca ; lipid peroxidation ; antioxidant defense ; G-proteins
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Abstract Long-term potentiation was elicited in living slices of rat olfactory cortex by stimulation of the lateral olfactory tract. A group of interdependent parameters of membrane metabolism was studied, i.e., the kinetics of45Ca metabolism, lipid peroxidation, and antioxidant defense; cytochemical measurements were made of Na+, K+-ATPase activity in neurons and glial cells; the functional (GTPase) activity of G-proteins was also studied. All parameters were compared with the bioelectrical activity of slices at three time points after tetanization, i.e., 3–5, 15, and 30 min. In most cases, regular phasic changes in metabolic parameters occurred, and their functional significance is discussed.
