Abstract
The effects of N-(2,6-dimethylphenyl)-2-(2-oxo-1-pyrrolidinyl) acetamide (nefiracetam; DM-9384), on learning and memory in several amnesia animal models with neuronal dysfunctions were investigated. Nefiracetam improved scopolamine-, bicuculline-, picrotoxin-, ethanol-, chlordiazepoxide- and cycloheximide-induced amnesia. Anti-amnesic action of nefiracetam on scopolamine model was antagonized by nifedipine and flunarizine, but not by diltiazem. Repeated administration of nefiracetam to AF64A-treated animals improved impairment of learning and memory as well as the alterations in cholinergic and monoaminergic neurotransmitters in the hippocampus. Basal forebrain (BF) lesioned rats induced by excitotoxin or by thermal coagulation showed impairment of learning accompanied by a marked reduction in choline acetyltransferase (ChAT) and acetylcholine esterase activities. Nefiracetam improved the learning deficit of the BF-lesioned rats. Nefiracetam also improved the carbon monoxide-induced delayed and acute amnesia. Nefiracetam stimulated acetylcholine release in the frontal cortex. Repeated administration of nefiracetam increased ChAT activity, gamma-aminobutyric acid (GABA) turnover and glutamic acid decarboxylase activity, and facilitated the Na(+)-dependent high-affinity GABA uptake. Nefiracetam activated the high voltage-activated (N/L-type) Ca2+ channel. The dose-response curves of nefiracetam were bell-shaped in both behavioral and biochemical studies. Therefore, it is suggested that nefiracetam improves the dysfunction of cholinergic, GABAergic and/or monoaminergic neuronal function by acting at Ca2+ channel and enhancing the release of neurotransmitters, and modifies impairment of memory processes induced by drugs and hypoxia.

Abstract
The effects of nefiracetam on GABA-induced chloride currents were studied with rat dorsal root ganglion neurons in primary culture using the whole-cell patch-clamp technique. The dose-response curve for GABA-induced currents was shifted by 16 microM to lower concentrations by 10 microM nefiracetam while the maximal response was reduced by 22.84 +/- 0.68%. Thus at a low concentration (10 microM) of GABA, the chloride currents were potentiated by nefiracetam in a concentration-dependent manner. With 10 microM nefiracetam, the potentiation occurred slowly and the recovery after washout was also slow. The desensitization of the GABAA receptor at high concentration (100 microM) of GABA was accelerated by nefiracetam. The recovery process of chloride currents from desensitization was not affected by nefiracetam. KT 5720 (0.56 microm), a specific protein kinase A (PKA) inhibitor, blocked the transient potentiation of GABA-activated currents by nefiracetam, but did not affect the acceleration of desensitization. Nefiracetam suppression of GABA-induced currents was also abolished by KT 5720 or the pertussis toxin. Thus, nefiracetam may inhibit Gi/G(o) proteins leading to a cascade of events that increase the intracellular cAMP level, activate the PKA system, and suppress GABA-induced currents. Nefiracetam-induced transient potentiation and acceleration of desensitization of GABA-induced currents may involve other pathways. The nefiracetam modulation of the GABAA receptor function will result in a nootropic effect on the central nervous system through modification of synaptic transmission.

Abstract
Scopolamine (0.15 mg/kg), a muscarinic antagonist, when administered during training or at a discrete 6-h posttraining time point, is demonstrated to inhibit the recall of a step-down passive avoidance response when tested at 24 and 48 h after task acquisition. Nefiracetam (3 mg/kg), a piracetam-related nootropic, when given with scopolamine during training tended to improve task recall, and this effect was more pronounced when given at the 6-h posttraining time. Co-administration of nefiracetam with scopolamine was not necessary to achieve the antiamnesic action, as nefiracetam given during training significantly improved the memory deficits produced by scopolamine at the 6-h posttraining time. The paradigm-specific increase in hippocampal neural cell adhesion molecule sialylation, which is observed during consolidation of a passive avoidance response, was attenuated by the presence of scopolamine during training and at the 6-h posttraining time, and this effect was reversed by co-administration of nefiracetam, albeit in a paradigm-independent manner. These results suggest nefiracetam exerts a neurotrophic action that protects memory consolidation from drug interventive insults.

Abstract
Apart from being a prominent (inhibitory) neurotransmitter that is widely distributed in the central and peripheral nervous system, gamma-aminobutyric acid (GABA) has turned out to exert trophic actions. In this manner GABA may modulate the neuroplastic capacity of neurons and neuron-like cells under various conditions in situ and in vitro. In the superior cervical ganglion (SCG) of adult rat, GABA induces the formation of free postsynaptic-like densities on the dendrites of principal neurons and enables implanted foreign (cholinergic) nerves to establish functional synaptic contacts, even while preexisting connections of the preganglionic axons persist. Apart from postsynaptic effects, GABA inhibits acetylcholine release from preganglionic nerve terminals and changes, at least transiently, the neurochemical markers of cholinergic innervation (acetylcholinesterase and nicotinic receptors). In murine neuroblastoma cells in vitro, GABA induces electron microscopic changes, which are similar in principle to those seen in the SCG. Both neuroplastic effects of GABA, in situ and in vitro, could be mimicked by sodium bromide, a hyperpolarizing agent. In addition, evidence is available that GABA via A- and/or B-receptors may exert direct trophic actions. The regulation of both types of trophic actions (direct, receptor-mediated vs. indirect, bioelectric activity dependent) is discussed.

Abstract
The effect of gamma-aminobutyric acid (GABA) on the expression of the neuron-associated D2 and neuron-specific enolase (NSE) was studied during development in culture of cerebellar granule cells. It was found that the presence of GABA during culture development increased the overall protein content. D2 content was also increased but not above the general increase in protein whereas NSE increased above the general level of protein. The presence of GABA in the growth medium also appeared to accelerate the changes in molecular forms of D2 and NSE seen during neuronal development. This suggests that GABA promotes or accelerates the general maturation of neurons, as these two neuron-associated proteins otherwise differ from each other with respect to their subcellular localization and their physiological and biochemical properties.

Abstract
The effects of elevated levels of GABA, glycine, or taurine on the rate of protein synthesis in plasma, brain, liver, and muscle of adult mice were measured in in vivo experiments after a flooding dose of labeled valine. Elevation of these amino acids caused hypothermia; keeping the animals in an incubator maintained physiological body temperature. The increase in GABA or glycine did not affect the rate of protein synthesis in these tissues to a significant degree. The increase in taurine levels caused inhibition of valine incorporation in plasma, liver, and muscle, while brain protein synthesis was unaffected. When glycine was increased in brain, the uptake of labeled free valine in the brain was greater.

Abstract
The in vivo metabolism of 14C-putrescine injected to rats before, during and after pregnancy was studied. Within 30 min of the administration of the isotope 9-12% of the injected radioactivity was recorded as 14CO2 in the expired air and after 5 h 60% was expired. The radioactivity excreted in the urine during the first day following the 14C-putrescine administration consisted of unmetabolized putrescine, gamma-aminobutyric acid (GABA) and some unidentified compound(s). No radioactive polyamines were detected in the urine. After treatment of pregnant rats with the diamine oxidase inhibitor aminoguanidine the expiration of 14CO2 was almost completely inhibited. In the urine increased amounts of unmetabolized putrescine were excreted while the excretion of GABA and the unidentified compound(s) were decreased. In addition 14C-spermidine appeared in the urine. The in vitro metabolism of putrescine was determined by the incubation of different tissues of pregnant and non-pregnant rats with 14C-putrescine. The 14C-metabolites derived via the diamine oxidase pathway (delta 1-pyrroline, GABA, some unidentified compound(s) and carbon dioxide) varied in magnitude with the tissue investigated. GABA was found to be a main metabolite of putrescine in several tissues of the pregnant rat. The content of putrescine and spermidine was elevated in several tissues as well as the blood on the 19th day of pregnancy in rats treated with aminoguanidine, while the content of spermine was unchanged.

Abstract
Altered in vivo and in vitro brain protein metabolism have been demonstrated in rodents following long-term ethanol ingestion. In the present study, ethanol effects were examined on properties of brain ribosomes of male Sprague-Dawley rats ingesting a specially formulated Lieber-DeCarli liquid diet. The development of physical dependence was demonstrated by the presence of withdrawal reactions within 24 hr of ethanol abstinence. Data showed significant inhibition of in vitro protein synthesis by ribosomes from the "ethanol" and "1-day-withdrawn" groups. Partial reversal of inhibition occurred by using a control brain pH 5 enzymes source instead of the matched source. The observed [14C]leucine-incorporating activity was temperature dependent, with the optimum temperature being 37 degrees C. The determination of the state of ribosomal aggregation showed an increased monosomes--disomes ratio in the "ethanol" group. The ratio was even more increased in the "1-day-withdrawn" group. Data suggest that reduced ribosomal binding to stable mRNA may be a contributing factor in the ethanol-induced effects on protein synthesis.

Abstract
Previous observations have demonstrated decreased in vivo and in vitro protein synthesis by brain ribosomal systems following long-term ethanol ingestion. For further investigation of the properties of brain ribosomes, the 40S and 60S ribosomal subunits were successfully isolated from control and chronic 10% ethanol-drinking rats. For a successful dissociation of ribosomes into subunits NH4Cl, puromycin and a high-salt treatment at 10 degrees C were essential with a critical concentration of Mg2+ since ribosomes could not be resolved at less than 7 mM Mg2+. Analysis of the A260 profile of the subunits on the sucrose gradients showed no significant differences between the control and ethanol-ingesting groups. Studies on 3H-labeled ribosomes following in vivo RNA labeling showed correspondence of the radioactive profiles from the incorporation of [5(-3) H) orotic acid into RNA with the sucrose gradient absorbance profile of 60S and 40S ribosomal subunits. Furthermore, active reassociation of both subunits occurred at 37 degrees C as demonstrated by the increased [14 C]-phenylalanine incorporation in the presence of poly(U). Results further showed that the poly(U)-dependent [14C]phenylalanine incorporation was significantly reduced by the subunits from the ethanol-ingesting animals. These findings suggest that long-term ingestion of ethanol caused functional changes in the properties of brain ribosomes, specifically on the reassociation process of the two subunits.

Abstract
The effects of ethanol withdrawal were determined on cell free brain protein synthesis in physically dependent rats. Following the development of physical dependence, ethanol abstinence for 24 h resulted in decreased protein synthesis in cerebral tissue. The observed inhibition of [14C]leucine incorporation into protein was found to be reversible after 7 days of ethanol withdrawal. Although the ribosomes from control, ethanol-treated and ethanol-withdrawn animals were highly responsive to polyuridylic acid stimulation, the ribosomes from the control group consistently exhibited higher activity. The determination of protein content of the ribosomal fraction showed a significant increase following ethanol administration and was further enhanced by ethanol abstinence. The results suggest that ethanol-induced changes at the ribosomal level may result in defective association of mRNA causing depression of brain protein synthesis.

Abstract
Rats had free access to 0.02% d-amphetamine solution instead of water for 23 days. The daily amphetamine consumption was found to increase from 16 mg/kg on day 1 up to 47 mg/kg on day 23. Tolerance to the anorexic effect of the drug was apparent on day 11. The initial depression in body weight persisted throughout the experiment. The hyperactivity of rats remained at the same level despite the daily increase in amphetamine intake. The incorporation of C14-leucine into cerebral cortex proteins was initially increased and returned to control level after 2 weeks of treatment. No direct correlation between hyperactivity and brain cortex protein synthesis was observed.

Abstract
Glutamate decarboxylase (GAD) activity and [14C)leucine incorporation into brain protein in vivo were measured in mice injected with L-glutamic acid-gamma-hydrazide and 60 min later with pyridoxal-5'-phosphate; this combined treatment produces a decrease in GAD activity and an increase in GABA levels. Under such conditions, protein synthesis was inhibited to the same extent as GAD activity. A parellelism between the decrease in GAD activity and that in protein synthesis was also observed in brain cortex slices treated with GAD inhibitors. This treatment did not affect leucine incorporation into protein in liver slices. The results support the previously suggested hypothesis that a certain pool of GABA may have a role in the regulation of protein synthesis in brain, and further suggest that the synthesis of GABA may be more important in this respect than its total concentration.
