Abstract:
Objective To explore the effects of A DH1B and A LDH2 gene polymorphism and type of al-coholic beverage on ethanol metabolism, to provide data support for cases involving the interpretation of ethanol metabolism or back calculation of blood ethanol concentration in forensic practice. Methods A total of 81 volunteers were selected. The genotypes of A DH1B, A DH1C and A LDH2 were obtained by a multiplex SNaPshot genotyping method. Each subject was administered with 1.0 g/kg of alcohol. About 1 mL venous blood was collected before and after the alcohol consumption at 30 min, 45 min, 1 h, 1.5 h, 2 h, 3 h, 4 h, 5 h, 6 h, 7 h and 8 h, respectively. The concentrations of ethanol and acetaldehyde in blood were determined by headspace gas chromatography. The peak times of blood ethanol concentration (Tmax), the peak mass concentrations of ethanol (Cmax), the area under curve (AUC) of ethanol (AUCethanol), AUCacetaldehyde and ethanol elimination rates (β) were calculated. In order to eliminate the influence of A DH1C, the A DH1C*1/*1 carriers were grouped based on the genotype of A DH1B and A LDH2. The data of each group were evaluated by one-way analysis of variance and pairwise comparison tests were performed by least significant difference method. The gene interactions were evaluated by two-way analysis of variance. Each parameter of three kinds of alcoholic beverage (white wine, red wine and beer) among groups was analysed by variance analysis with randomized block design. Results There were no differences in the value of Tmax and Cmax between the groups with different A DH1B and A LDH2 genotype. The differences in the values of AUCethanol, β and AUCacetaldehyde among some groups carrying different A DH1B and A LDH2 geno-type had statistical significance, while no significant difference was observed in these parameters when one individual taking same dose of different alcoholic beverage type. Conclusion The ethanol metabolism is associated with the related gene polymorphism, which is barely affected by alcoholic beverage type.
