Abstract
Given the observable toxicity of lithium carbonate, neuropharmacology requires effective and non-toxic lithium salts. In particular, these salts can be employed as neuroprotective agents since lithium ions demonstrate neuroprotective properties through inhibition of glycogen synthetase kinase-3β and other target proteins, increasing concentrations of endogenous neurotrofic factors. The results of theoretical and experimental studies of organic lithium salts presented here indicate their potential as neuroprotectors. Chemoreactomic modeling of lithium salts made it possible to select lithium ascorbate as a suitable candidate for further research. A neurocytological study on cerebellar granular neurons in culture under conditions of moderate glutamate stress showed that lithium ascorbate was more effective in supporting neuronal survival than chloride or carbonate, i.e., inorganic lithium salts. Biodistribution studies indicated accumulation of lithium ions in a sort of “depot”, potentially consisting of the brain, aorta, and femur. Lithium ascorbate is characterized by extremely low acute and chronic toxicity (LD50 > 5000 mg/kg) and also shows a moderate antitumor effect when used in doses studied (5 or 10 mg/kg). Studies on the model of alcohol intoxication in rats have shown that intake of lithium ascorbate in doses either 5, 10 or 30 mg/kg did not only reduced brain damage due to ischemia, but also improved the preservation of myelin sheaths of neurons.

Abstract
The deuterium content modification in an organism has a neuroprotective effect during the hypoxia model, affecting anxiety, memory and stress resistance. The aim of this work was to elucidate the possible mechanisms of the medium D/H composition modification on nerve cells. We studied the effect of an incubation medium with a 50 ppm deuterium content compared to a medium with 150 ppm on: (1) the activity of Wistar rats' hippocampus CA1 field neurons, (2) the level of cultured cerebellar neuron death during glucose deprivation and temperature stress, (3) mitochondrial membrane potential (MMP) and the generation of reactive oxygen species in cultures of cerebellar neurons. The results of the analysis showed that the incubation of hippocampal sections in a medium with a 50 ppm deuterium reduced the amplitude of the pop-spike. The restoration of neuron activity was observed when sections were returned to the incubation medium with a 150 ppm deuterium content. An environment with a 50 ppm deuterium did not significantly affect the level of reactive oxygen species in neuron cultures, while MMP decreased by 16-20%. In experiments with glucose deprivation and temperature stress, the medium with 50 ppm increased the death of neurons. Thus, a short exposure of nerve cells in the medium with 50 ppm deuterium acts as an additional stressful factor, which is possibly associated with the violation of the cell energy balance. The decrease in the mitochondrial membrane potential, which is known to be associated with ATP synthesis, indicates that this effect may be associated with the cell energy imbalance. The decrease in the activity of the CA1 field hippocampal neurons may reflect reversible adaptive changes in the operation of fast-reacting ion channels.

Abstract
Addition into the culture medium of the antioxidant N-acetylcysteine (NAC, 1 mM) in the presence of Cu2+ (0.0005-0.001 mM) induced intensive death of cultured rat cerebellar granule neurons, which was significantly decreased by the zinc ion chelator TPEN (N,N,N',N'-tetrakis(2-pyridylmethyl)ethylenediamine). However, the combined action of NAC and Zn2+ did not induce destruction of the neurons. Measurement of the relative intracellular concentration of Zn2+ with the fluorescent probe FluoZin-3 AM or of free radical production using a CellROX Green showed that incubation of the culture for 4 h with Cu2+ and NAC induced an intensive increase in the fluorescence of CellROX Green but not of FluoZin-3. Probably, the protective effect of TPEN in this case could be mediated by its ability to chelate Cu2+. Incubation of cultures in a balanced salt solution in the presence of 0.01 mM Cu2+ caused neuronal death already after 1 h if the NAC concentration in the solution was within 0.005-0.05 mM. NAC at higher concentrations (0.1-1 mM) together with 0.01 mM Cu2+ did not cause the death of neurons. These data imply that the antioxidant NAC can be potentially harmful to neurons even in the presence of nanomolar concentrations of variable valence metals.

Abstract
Streptozotocin (STZ) is a glucosamine-nitrosourea compound used for experimental simulation of sporadic Alzheimer's disease at intracerebroventricular administration in vivo. The studies of STZ influence on neurons of central nervous system performed on the primary cultures are practically absent. We have shown the application of STZ (1-5mM) in primary culture for 48h induced strong dose-dependent death in cultured cerebellar granule neurons. This toxic effect was decreased by pyruvate, insulin partially. Using the indicator Fluo-4 AM for measurements of intracellular calcium ions and tetramethylrhodamine ethyl ester (TMRE) for detection of changes of mitochondrial membrane potential in live cells we have shown that 5 h-exposure to STZ induced intensive increase of Fluo-4 and decrease TMRE fluorescence in neurons. STZ exposure caused considerable ultrastructural alterations in granule neurons: chromatin clumping, swelling of the endoplasmic reticulum and mitochondria, and disruption of the mitochondrial cristae. Probably, STZ significantly impaired glucose metabolism and mitochondrial function that, in turn, resulted in mitochondrial membrane potential damage, excessive calcium overload and neuronal death.

Abstract
A protective behavioral effect of a nerve growth factor dipeptide mimetic GK-2 in the model of open focal trauma of rat brain sensorimotor cortex and its antioxidative and regenerative properties in cultures of rat cerebellar granule cells and mouse embryonal spinal ganglion, respectively, were studied. Intraperitoneal injections of GK-2 (1 mg/kg) for 5 days daily after traumatic brain injury improved significantly motor function of limbs. Moreover, supplementation the incubation medium with GK-2 (0.5-1.5 mg/l) decreased neuronal death induced by H2O2 in cerebellar granule cell cultures and stimulated neurite outgrowth from cultured mouse embryonal spinal ganglia. Our results suggest that GK-2 exhibits pronounced positive behavioral effect in vivo as well as neuroprotective and regenerative effects in vitro, and that these neuroprotective properties probably associated with cell survival but not with cell differentiation pathway.

Abstract
Zinc chloride (0.02 mM, 3h) did not have any influence on the survival of cerebellar granule neurons (CGNs) incubated in balanced salt solution (BSS). However, in the absence of glucose ZnCl(2) caused severe neuronal damage, decreasing cell survival to 12±2%. Either the blockade of ionotropic glutamate NMDA-receptors with MK-801 or APV or supplementation the medium with ruthenium red (mitochondrial Ca(2+) uniporter blocker) almost entirely protected CGNs from the toxic effect of ZnCl(2) during glucose deprivation (GD). However, NBQX (AMPA/kainate glutamate receptor blocker) did not show protective effect. Measurements of intracellular calcium ions concentration using fluorescent probe (Fluo-4 AM) and zinc ions (FluoZin-3AM) demonstrated that 1.5h-exposure to GD induced intensive increase of Fluo-4 fluorescence and small increase of FluoZin-3 fluorescence in neurons. The supplementation of medium with ZnCl(2) caused equal increase of FluoZin-3 fluorescence at both GD and normoglycemia, whereas the potentiation of Fluo-4 fluorescence by zinc was observed only under GD and could be prevented by MK-801. However, neither MK-801 nor NBQX could influence [Zn(2+)](i) increase caused by zinc addition under GD, while ruthenium red did cause significant increase of [Zn(2+)](i). This data implies that zinc ions during GD induce an additional overload of CGNs with calcium ions that get transported through activated NMDA-channel. Zinc and calcium ions accumulate in mitochondria and amplify individual destructive action on these organelles leading to neuronal death.
