[Change in pancreatic exocrine function in acute appendicitis].

In order to study changes in the functional state of the pancreas 1572 investigations of the blood and urine amylase, atoxylresistant lipase of the blood serum before operation were performed in different postoperative periods in 131 patients with acute appendicitis. The enzyme activity was established to increase, especially in destructive forms of appendicitis and in elderly patients.

[The quantitative parameters of the vertical migration of radionuclides in the soils in different types of meadows].

The two-component convective-diffusional model was used for determination of vertical migration parameters of 90Sr [correction of 90Cs] and 137Cs in meadow ecosystems and dependence from meadow type and soil properties was shown. The migration coefficients decrease in the order: peat land, lowland meadows, flood-plain meadows, dry meadows. The ecological half-life in the root zone ranges from 55 to 143 y for dry meadows and from 15 to 21 y for peat lands. Analogous parameters for 90Sr was 30-96 and 13-18 y, respectively. Since 1987 to 1994 the ecological half-life of 137Cs increased by a factor of 1.7-6.0.
