Analyzing the trends in the development of ophthalmology development in this country and abroad, the author comes to a conclusion that the market economy may result in deterioration of the quality of treatment. Development of exitology, a science of the treatment outcomes, may inhibit the development of such trends; this science is supposed to assess the known therapeutic methods basing not only on their authors' recommendations, but mainly on the basis of sociologic studies with the patients participating in these studies.

Possibilities of the usage of different models of flexible ophthalmic endoscopes in diagnosis and treatment of intraocular eye pathology have been studied. The paper presents data about the usage of endoscopes at the time of intraocular operations in the "closed" eye of 25 patients with pathologic changes of different etiology in the posterior segment of the eye (25 eyes). Comparative analysis of possibilities of the usage of different models has revealed advantages of endoscopes with combined observation and illumination channels and with a wide-angle objective. Different methods for the usage of flexible ophthalmic endoscopes are described. It is pointed out that ophthalmic endoscopy, by giving a surgeon additional information about intraocular changes, allows the operation of a closed type in vitreoretinal pathology to be much more effective.

The protective effect of remantadin during an influenza outbreak in December 1977 caused by A (H1N1) virus was studied. A prophylactic administration of remantadin decreased influenza and ARD incidence by 1.5-fold. A more significant decrease of the incidence (2.5-fold) was observed among the subjects given a combination of remantadin and influenza vaccine (H3N2) a few days before the outbreak, which was apparently due to the interferon-inducing capacity of the vaccine.

During a long-term flight on Salyut-7 and Mir orbital stations a contact lens was used for the first time in order to correct mild ametropia of one of the crew members. He used a soft contact lens for 5 hrs on flight days 10, 30, 45 and 60. As a result, acuity of vision of the treated eye increased to 1.5. This study showed that contact lenses can be employed in space flight.

Lungs of 9127 small mammals of 17 species trapped in Khabarovsk region, Magadan, Amur, and Sakhalin regions in 1982-1987 were examined, among them 11 species are reservoirs of HFRS virus. Most frequently infected are striped field mice and Japanese field mice, red voles and large-toothed red-backed voles which are the dominant species of the appropriate landscape formations. Circulation of two HFRS virus serotypes among small mammals was demonstrated. The main epidemiological role belongs to the striped field mouse in HFRS foci of the meadow-field type, and to Asiatic field mouse in forest foci in the territories examined.
