  • Publication number: 20170266155
    Abstract: The present invention relates to a method for substituting for or acting with the hyperbaric oxygen therapy to improve hypoxia, comprising the step of: administrating a phthalide compound to a subject in need thereof, wherein the phthalide compound can increase the oxygen release efficiency of blood hemoglobin (Hb) in the subject and further increase the cellular oxygenation level, and when the phthalide compound substitutes for or act with the hyperbaric oxygen therapy, the common adverse side effects of the hyperbaric oxygen therapy, such as barotrauma, decompression sickness and oxygen poisoning, are prevented. The phthalide compound is used to substitute for or act with 2,3-BPG, to modulate and decrease the oxygen affinity of hemoglobin (Hb), to increase the oxygen release efficiency of hemoglobin (Hb) to tissue cells, thereby achieving a normal cellular oxygenation level and maintaining the cellular oxygenation level in a normal range.

  • Publication number: 20170266156
    Abstract: The present invention relates to a method for preventing cancer by using a phthalide compound, wherein the phthalide compound has an effect of increasing the oxygen release efficiency of hemoglobin (Hb) of a subject to increase the oxygenation level of organs and tissue cells, thereby preventing the cellular oxygenation level against falling below the critical cellular oxygen requirements under which the normal cells can turn cancerous. Although cancer may be caused by a variety of reasons, including congenital inheritance, external environment, air pollution or poor living and dietary habits, there is only one primary and common reason in causing cancers, the excessively low cellular oxygenation level. When the oxygenation level of any cell falls below 60% of its physiological oxygen requirements, the normal cell may turn cancerous.
