dehydroascorbic acid/hemorrhage

Ascorbic acid is a vitamin soluble in water and its deficiency in human body causes scurvy. Its symptoms in adults are gingivitis, susceptibility of blood vessels to damage and bleeding, changes in bones and cartilage and retarded wound healing. Ascorbic acid is necessary in redox processes taking

Neuronal injury in ischemic stroke is partly mediated by cytotoxic reactive oxygen species. Although the antioxidant ascorbic acid (AA) or vitamin C does not penetrate the blood-brain barrier (BBB), its oxidized form, dehydroascorbic acid (DHA), enters the brain by means of facilitative transport.

Concentrations of histamine and total ascorbic acid (L-ascorbic acid plus dehydroascorbic acid) in the antecubital vein blood of women in abruptio placentae (normally situated placentae) and placenta praevia have been measured. The results show that blood ascorbic acid in abruptio placentae is

Levels of ascoroic acid, its oxidized forms, dehydroascorbic acid (DHA) and diketogulonic aci (DKGA), and the sum of all forms of ascorbic acid (SAA) were investigated in aging red blood cells produced under physiological and stress conditions (massive hemorrhage) Aging of red blood cells o intact
