[Effect of pantogam on visual function and hemodynamic of eyes in patients with primary open-angle glaucoma].

The complex therapy in patients with primary open-angle glaucoma, with normalized intraocular pressure but with declined visual functions included the use of the Russian neurometabolic preparation pantogam. The improvement of the visual function appeared as enlargement of the borders of visual fields, decreased area and sensitivity deficit (according to computer perimetric data). Doppler ultrasonography has demonstrated an increase in the mean blood velocity in the orbital vessels and a decrease in eyeball blood supply defects after pantogam therapy which is a favourable sign of a glaucomatous process.

[Th1-cytokines in chronic hepatitis B and C].

Forty-four patients with chronic HBV and HCV were observed. Serum levels of interferon-gamma (IFN-gamma), interleukin-2 (IL-2), and soluble IL-2 receptor (IL-2r) were measured by enzyme immunoassay in 29 patients divided into 3 groups: group 1 (n = 9) with chronic HBV, group 2 (n = 9) with chronic HCV, and group 3 (n = 11) with mixed HBV + HCV infection. Control group consisted of 10 normal subjects without HBV, HCV, or HIV infection markers.

[Hepatitis A in Estonia (1990-1999)].

During recent 10 years (1990-1999) essential changes occurred the epidemiology of viral hepatitis A (VHA) in Estonia: simultaneously with a decreased level of morbidity (morbidity rate per 100,000 of the population was 78.4 in 1990 and 7.7 in 1996, or 1,241 and 112 cases, respectively), a shift in the age structure of patients from children of preschool age to older age groups took place.
