    摘要: The present invention relates to low concentration synergistic Xenon-Argon gas mixtures as organ protectant, in particular as neuroprotectant. Specifically, the present invention relates to a pharmaceutical composition comprising a gas mixture of xenon and argon for use as organ protectant, in particular as neuroprotectant, wherein
    - the volume proportion of xenon is between 5 and 25%,
    - the volume proportion of argon is between 5 and 25%, and
    - the pharmaceutical composition further comprises a gas complement to reach 100% volume proportion.
    More specifically, the pharmaceutical composition of the invention is useful for treating and/or preventing and/or slowing the degradation of the structure and/or function of organ cells (in particular neurons), in mammals suffering a decompression accident, neonatal hypoxia-ischemia, stroke, traumatic brain injury, cardiac arrest, renal dysfunction, neurocognitive disorders, post-traumatic stress disorder (PTSD), neurodegenerative diseases, and psychiatric disorders.
