ABSTRACT
Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.
ABSTRACT
OBJECTIVE@#To analyze the blood type of a family with B(A) blood type.@*METHODS@#The serological blood type of the family was determined by routine tube method. Exons 6 and 7 of the ABO gene were amplified by PCR and subjected to Sanger sequencing.@*RESULTS@#Serological testing of the proband and her elder son showed a discrepancy which was initially identified as B(A) subtype. Her husband and second son were identified as blood type O. Sequencing of the proband and her elder son has identified an O allele and a 640A>G mutation compared with the B gene. Her husband and second son possessed the same genotype of O/O.@*CONCLUSION@#The 640A>G mutation of ABO gene probably underlies the B(A) subtype.
