- the rats were immediately placed for 3 hours in a closed enclosure, with a volume of 100 liters, swept in dynamic regime at a constant flow rate of 5 l.min- 1 , either by air (Group 1 : saline; Group 2: Amph), either with nitrous oxide at 50% by volume (Group 3: saline; Group 4: Amph) or 75% (Group
- the locomotor activity of animals in groups 1 to 10 was evaluated on D6, after an ip injection of saline solution (1 ml / kg), and on D7 after a ip injection of d-amphetamine (1 mg / ml / kg).
- the locomotor activity of animals in response to these injections was recorded using actimetry cages with photoelectric cells (Imperinic, Pessac, France).
- neurochemical studies in addition to the histological and behavioral studies above, were carried out on slices of the brains of these rats in order to identify the mechanisms of the action of nitrous oxide and xenon, and in order to assess the neurotoxic potential of nitrous oxide and xenon.
- the animals were sacrificed on D8 by decapitation under general anesthesia with halothane, then the cranial box immediately placed in a solution of paraformaldehyde for one week.
- the brain was removed, embedded in paraffin and sectioned into 4 ⁇ m frontal sections mounted on gelatinized slides and stained with a hemalun-eosin-saffron solution.
- the posterior and retrosplenial cingulate cortices were analyzed under an optical microscope (x 400).
- the preparation of accumbens core slices was carried out as follows. The animals were decapitated under light halothane anesthesia, then the brain quickly removed.
- the brain slices were placed for recovery in buffered saline at a temperature of 3-4 ° C for at least 1 hour before use for neurochemical study.
- the measurement of dopamine release was carried out by the normal differential pulse voltammetry technique using a single fiber carbon electrode with a diameter of 10 ⁇ m and length 250 ⁇ m (CFN10-250; World Precision Instruments, Aston,
- the rat brain slices were then placed in an organ tank and perfused with an artificial cerebrospinal fluid of composition: NaCI 118mM, MgCI ⁇ 1.18 mM, KCI 4.9 mM, NaH 2 P0 4 1.25 mM, CaCI 2 1.25 mM, NaHC0 3 3.6 mM, d-glucose 10 mM, HEPES 30 mM, pH 7.4, whose temperature was regulated to 34 ⁇ 1 ° C by means of a temperature controller (Delta 4 Culture Dish Controller, Bioptechs, Butler, PA, USA) .
- a temperature controller Delta 4 Culture Dish Controller, Bioptechs, Butler, PA, USA
- the electrode was placed under microscopic control (EFN 600 microscope, Nikon, Paris, France), 100 ⁇ m from the anterior commissure, using an optical micrometer incorporated into the microscope, then completely lowered into the accumbens nucleus, according to an angle of 45 °, and connected to the Biopulse polarograph set in normal differential pulse voltammetry mode with the following parameters: scanning potential -150 + 350 mV; scanning time 0.4s, scanning amplitude 4 mV, for a scanning speed of 10 mV.s- 1 ; measurement pulse 40 ms; measurement pre-pulse 70 ms; measuring range 30 mV.
- Dopaminergic hyperstimulation was induced by adding d-amphetamine to the infusion fluid, medical air, nitrous oxide or xenon was dissolved, until saturation, before use in the infusion fluid, including pH was readjusted to 7.4.
- D-amphetamine d-amphetamine sulfate, ref. A5880
- FIG. 1 and 2 illustrate the sensitization process induced by the repeated administration of d-amphetamine since: - Figure 1 shows the effects of nitrous oxide at 50 vol% and 75 vol% (oxygen rest) on awareness of d-amphetamine; and - Figure 2 illustrates the effects of xenon at 50% and 75% on sensitization to d-amphetamine.
- FIG. 1 a histological study of the posterior and retroplenial cingulate cortex shows in rats exposed to xenon at 75 vol% a generalized cytoplasmic clarification associated with a picnotic aspect of the cell nuclei, as well as the appearance in some animals of cytoplasmic vacuoles, which suggest , in accordance with motor activity, a neurotoxic effect of repeated administration, 3 consecutive days, of xenon at 75 vol%. No similar effect was found in rats exposed to medical air, 75 vol% nitrous oxide, or 50 vol% xenon.
- Figure 3 illustrates the effects of nitrous oxide on the increase in dopamine release in the nucleus accumbens induced by d-amphetamine.
- NMDA nicotinic type cholinergic receptors
- the results obtained show that 75 vol% of nitrous oxide and only 50 vol% of xenon are necessary to block the sensitization process.
- the use of 75% xenon is not recommended.
- the animals pretreated (from D1 to D3) with a saline solution and xenon at 75% show a locomotor activity greater than that of the control animals pretreated with saline + air, during the d-amphetamine test (performed on D7), which could account for sensitization of the NMDA receptors.
- nitrous oxide at 75 vol. % or xenon at 50 vol.% and 75 vol.% block the process of behavioral sensitization to d-amphetamine but xenon at 75 vol% also induces an increase in the acute response to d-amphetamine which could reflect a modification receptor sensitivity and a potentially deleterious process, which supports histological studies.
- nitrous oxide and xenon at 50 vol% or 75 vol% block the increase in dopamine release induced by d-amphetamine. All these results show the undeniable inhibitory effects of nitrous oxide and xenon on awareness of d-amphetamine and the neurochemical processes associated with it.
- gas mixtures containing 5 and 35% by volume of xenon gas and 10 and 50% by volume of nitrous oxide gas (and oxygen for the rest) are entirely suitable for use as inhalable gas drug used to prevent or treat neuro-intoxication in humans or animals. Indeed, by using suitable mixtures based on xenon and nitrous oxide, one can benefit from the effects of these two compounds without encountering the above-mentioned problems.
- the gas mixture of the invention can be used to treat all neurointoxications.
- Neuro-intoxication means a disorder, disorder or pathology of the central nervous system, the etiopathogeny of which involves, at least in part, an excito-toxic process, in particular a dysfunction of the excitatory neurotransmission to glutamate; see in particular the document Parsons et al., Drug News Perspect, 1998, vol.11, pages 523-569.
- an addiction such as amphetamines and amphetamine derivatives, opiate substances and their derivatives, cocaine and its derivatives, tobacco, cannabis and / or alcohol
- acute stroke such as head trauma and stroke, including cerebral ischemia
- neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, Huntington's disease (chorea), amyotrophic lateral sclerosis, acute disseminated encephalomyelitis, tardive dyskinesia, and olivopontocerebellar degeneration
- various psychiatric or neurological pathologies such as anxiety disorders, psychotic disorders, in particular schizophrenia and epilepsy in its various forms.
