Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to ophthalmology, namely to dacryology. To determine dacryostenosis stages, cytologycal examination of lacrimal sac and nasolacrimal duct fluids is fulfilled, sampled after single lavage with coloured solution, via higher or lower lacrimal point and respective tubule, until the solution appears in nasolacrimal duct ostium. Inflammation stage of dacryostenosis is determined by detection of microbe colonies, leucocytic infiltration, raised desquamation of dystrophic epitheliocytes, lining nasolacrimal duct. Fibroisation stage is determined in the infiltrate by presence of whole layers of necrotic epithelium, prevalence of fibroblasts, concluded in dense, membrane-like material.

Abstract: FIELD: oil and gas industry. 
     SUBSTANCE: invention refers to oil industry and can be implemented at development of oil deposit in cyclic mode. The invention facilitates increased oil yield of the deposit. The method consists in withdrawing of oil through producers, in pumping working agent via pressure wells, in determining intake capacity of pressure wells and in taking it into account at specifying modes of operation for pressure wells. Measurements of intake capacity and pressure of pumping are carried out at the pressure wells after constant mode of operation has been established. If idle time has lasted to 10 hours, measurements of intake capacity are taken not earlier, than in 3 hours. In case of prolonged idle time, like 10-15 days, measurements of intake capacity are started not earlier, than in 2 days. If intake capacity of pressure wells operating in continuous mode with capacity over 40 m 3 /day has risen, these wells are transferred to a short-term cyclic mode during 1-4 months till former intake capacity returns. Pressure wells with low intake capacity operating under continuous mode with level of capacity about 15-20 m 3 /day are transferred to a short-term cyclic mode of operation till rise of their intake capacity. Further, wells are returned to a constant mode of pumping.
