Risk of thyroid cancer among chernobyl liquidators.

After the Chernobyl accident in 1986, the "liquidators" or clean-up workers were among those who received the highest radiation doses to the thyroid from external radiation. Some were also exposed to radioiodines through inhalation or ingestion. A collaborative case-control study nested within cohorts of Belarusian, Russian and Baltic liquidators was conducted to evaluate the radiation-induced risk of thyroid cancer.

Thyroid mass in children and adolescents living in the most exposed areas to Chernobyl fallout in Belarus.

This paper aims to determine the thyroid volumes in children and teenagers living in Gomel and Mogilev Oblasts, which are the areas of Belarus that were most affected by the Chernobyl accident. Results of thyroid volume measurements performed in 1991-1996 by the Sasakawa Memorial Health Foundation were used to evaluate the variation by age of the thyroid volumes for girls and boys aged from 5 to 16 y. Thyroid volumes for age groups without measurements were also estimated.

[Effect of mucolytic therapy on the production of reactive oxygen species in the blood of patients with an exacerbation of chronic obstructive pulmonary disease].

Aim: To study the production of active oxygen forms (AOF) in the blood of patients with an exacerbation of chronic obstructive pulmonary disease (COPD) and the effect of the mycolytic agent Ambroxol on this process.

Subjects And Methods: Fifty-two patients with an exacerbation of COPD were examined. The patients were divided into 2 groups: 1) a study group (n = 25) received conventional therapy (antibiotics, bronchodilators, glucocorticosteroids) and Ambroxol inhalation; 2) a control group (n = 27) had conventional therapy and placebo (saline) inhalation.
