PurposeTo discuss the relationship between the acute cerebral infarction of differently aged population and the variable number tandem repeat polymorphism of endothelial nitric oxide synthase (eNOS) gene.MethodsThe genotypes of 129 acute cerebral infarction patients and 100 healthy control subjects were determined by PCR and polyacrylamide gel electrophoresis (PAGE).ResultsIn the patient group, the frequency of allelic gene a was higher than that in the control group (13.56 % vs 3 %, p < 0.01), and the frequencies of the patients followed the descending order from young through middle-aged to elderly (42.31 % vs 17.2 % vs 5.8 %). The frequencies of the young, middle-aged and elderly population in the control group differed significantly (5.55 % vs 2.94 % vs 2.63 %), and those of the young and middle-aged population in the two groups also differed statistically significantly.ConclusionThe ab genotype of eNOS 4th intron is correlated with the acute cerebral infarction of young and middle-aged Chinese Han population that may involve allelic gene a as an independent risk factor (Tab. 3, Fig. 3, Ref. 13).
