Abstract:
OBJECTIVE:To investigate the anti-oxidative effect of ethyl pyruvate (EP) and taurine (TAU) on the quality of red blood cells stored at 4±2 ℃, hemolysis, energy metabolism and lipid peroxidation of the red blood cells in the preservation solution were studied at different intervals.
METHODS:At 4±2 ℃, the deleukocyte red blood cells were stored in the citrate-phosphate-dextrosesaline-adenine-1 (CPDA-1) preservation (control group), preservation solution with EP (EP-AS), and TAU (TAU-AS) for long-term preservation. The enzyme-linked immunoassay and automatic blood cell analyzer were used to detect hemolysis and erythrocyte parameters. Adenine nucleoside triphosphate (ATP), glycerol 2,3-diphosphate (2,3-DPG) and malondialdehyde (MDA) kits were used to test the ATP, 2,3-DPG and MDA concentration.
RESULTS:During the preservation, the rate of red blood cell hemolysis in EP-AS and TAU-AS groups were significantly lower than that in CPDA-1 group (P<0.01). The MCV of EP-AS group was increased with the preservation time (r=0.71), while the MCV of the TAU-AS group was significantly lower than that in the other two groups (P<0.05). The concentration of ATP and MDA in EP-AS and TAU-AS groups were significantly higher than that in CPDA-1 group at the 14th day (P<0.01). The concentrations of 2,3-DPG in the EP-AS and TAU-AS groups were significantly higher than that in the CPDA-1 group from the 7th day (P<0.01).
CONCLUSION:EP and TAU can significantly reduce the red blood cell hemolysis rate, inhibit the lipid peroxidation level of red blood cells, and improve the energy metabolism of red blood cells during storage. The mechanism of EP and TAU may be related to their antioxidation and membrane protection effect, so as to improve the red blood cell quality and extend the preservation time.
