[Applying the DNA diagnostics in patients with superficial keratitis of viral origin].

Aim: The authors evaluate the significance of the DNA diagnostics in patients with superficial keratitis of viral origin and their capability to be used for monitoring of the treatment effectiveness in the follow-up. The presence of herpes simplex virus 1 and 2, varicella zoster virus (HSV 1, HSV 2, VZV), and adenoviruses was assessed by means of the DNA analysis.

Material And Methods: The group consisted of 54 patients (33 men and 21 women), mean age 45.

Polymorphism of DRD2 gene and ADHD.

Objectives: Attention deficit hyperactivity disorder (ADHD) is a prevalent childhood disorder. Evidence from the family and twin studies suggest that ADHD is familiar and highly heritable. Association studies are frequently used for the searching of markers responsible for genetic basis of ADHD.

The association between high-activity COMT allele and alcoholism.

Objectives: The catechol-O-methyltransferase (COMT) is an enzyme involved in the metabolism of dopamine, adrenaline and noradrenaline. The Val158Met polymorphism of the COMT gene has been previously associated with a variability of the COMT activity, and alcoholism. The aim of the present association study was to examine the relationship between the Val158Met polymorphism of the COMT gene and dispositions to alcoholism.
