RESUMEN
The dependence of radon adsorption on the content of adsorbed water of activated carbon fabrics of ACC-5092-10 and ACC-5092-20 was studied experimentally. Specimens with different content of adsorbed water (from zero to saturation level) were coupled with alpha-track detector and exposed to reference 222Rn concentration. Both materials demonstrated different properties: Radon adsorption in ACC-5092-10 smoothly and monotonically decreases with the increase of adsorbed water and at saturation level it is lower by a factor of 2.5 as compared to the fully dehydrated material. In ACC-5092-20 clear break point was observed at water content of about 20% where radon adsorption sharply drops by a factor of 15. ACC-5092-10 was identified as a material that keeps its high radon adsorption ability even when saturated with water. Coupled with alpha-track detector it may be used for sensitive long-term measurements 222Rn measurements even at high levels of humidity.
RESUMEN
For the first time in the bulgarian literature a case with pancreatic oncocytoma is described, initially diagnosed as carcinoma. The patient survived for 13 years being nowadays in perfect condition.

Results are reported of a clinical examination and surgical treatment of seven cases with gastro-jejunocolic fistulas and five cases with gastroileoanastomosis. The clinical picture, irrigography, steatorrhea, hypoproteinemia, etc. are stressed upon as important for the diagnosis. The operation result depended on the degree of the resorbtive disturbances, on successful reanimation and frequent postoperative complications. Postoperative lethality is five out of 12 cases.
