Stimulation of Basal Secretion in the Treatment of Dry Eye Syndrome

The aim is to evaluate the effectiveness of Stillavit in the treatment of dry eye syndrome (DES) and its effect on the density of conjunctival goblet cells and the functional parameters of tear production. Methods. There were analyzed treatment results of 18 patients (36 eyes) with DES at the age of 48 to 80 years (average 60.6 ± 1.3 years) including 17 women and 1 male before and after 1 and 3 months after Stillavit prescription. In all patients in addition to a standard ophthalmological examination the results of Schirmer I, Norn, as well as the LIPCOF test were evaluated and the density of conjunctival goblet cells was examined. Results. After 1 and 3 months there was a significant improvement in the results of the Norn test: from 5.17 ± 0.22 seconds to 7.18 ± 0.17 seconds which indicated an increase in the stability of the tear film. After 3 months there was a significant increase in the density of conjunctival goblet cells, improvement in the Schirmer sample: from 9.26 ± 0.89 to 11.7 ± 0.6 mm (t = 2.28, p < 0.05) and LIPCOF test (t = 2.18, p < 0.05) which indicated an increase in tear production and a significant decrease in the inflammatory process and edema of the conjunctiva. Conclusion. Treatment of DES with the use of Stillavit leads after 3 months to a significant increase in the density of conjunctival goblet cells, increases tear production and stability of the tear film

High-temperature kinetic properties of Fe-Ge solid solutions

Temperature and concentrational dependences of the electrical resistivity ρ, thermoelectric power S, and thermal diffusivity a of solid solutions of Ge in Fe were studied at high temperatures. The a(T) dependences of the alloys with 0.0, 0.31, 0.8, 1.08, and 2.6 at. % Ge exhibit anomalies near the temperature of the β-γ transformation; in this case, changes in the spectra of inner electron levels are observed. The high-temperature kinetic properties of solid solutions of Ge in Fe are close to those of metals and, therefore, the ρ(T) and a(T) dependences can be explained using the model of two-band conduction
