RESUMO
The article presents a case of chronic odontogenic maxillary sinusitis and the results of its surgical treatment. The cause of the sinusitis, confirmed by the results of X-ray and pathohistological studies, was an inflammatory process affecting the bone tissue around the implant, installed in the place of the upper first molar which was accompanied by the development of an oroantral fistula. During the surgical intervention, the communication between the oral cavity and the maxillary sinus was eliminated, and the implant with the abutment, which was entirely in its cavity, was also removed.

Histological and electron microscopic changes in the hepatic structure were studied in animals with acute experimental cholecystitis. The administration of the succinate-containing drugs reamberin and mexidole decreased the magnitude of morphological changes in the liver tissue. Morphometric examination revealed that reamberin versus mexidole showed a high efficacy in reducing the area of hepatocytic necrosis.

Histologic mounts of 20 decalcified teeth were studied, the roots of the teeth after extraction preserved the connection with the periapical formation. Analysis of the received morphological data let make more exact the mechanism of forming and persisting the inflammation focus round dental root apex and give practical recommendations how to treat chronic apical periodontitis.

Early and late effects of short-living iodine isotopes on the thyroid of children in Byelarus are described. Early effects manifested with an increase in the thyroid functional activity in children up to one year of age during 1986. Follicular cell hypertrophy is considered as a marker of the radiation effect at a dose level from 0.1 to 1 krad. Late effects are thyroid carcinomas the incidence of which in the country rose ten-fold within the last 5 years.
