PON1 and alkaline phosphatase measurement: The decrease in the activities of PON1(P) and PON1(A) was found in the blood of AP patients with the CC genotypes compared to individuals with the TC genotypes (PON1(P): p = 0.0004 and p < 0.0001 on the third and seventh day, respectively in the group of non-smokers and p < 0.0001 on the seventh day in the group of smokers; PON1(A): p = 0.0009 and p = 0.0328 on the third and the seventh day, respectively, in the group of non-smokers).
