[Laser treatment of the eyes of microsurgical needles]. / Lazernaia obrabotka otverstii mikrokhirurgicheskikh igl.

Experimental results of studies on ability to treat by laser beam holes into needles by 0.15-1.0 mm diameter made of steel are presented. Operating conditions such as radiant energy, pulse duration and frequency are specified.

[Optimal coefficient of overlap of light spots during laser hardening of medical instruments]. / Optimal'nyi koéffitsient perekrytiia svetovykh piaten pri lazernom uprochenii meditsinskikh instrumentov.

The optimum coefficient of light spot intercepts in the course of laser hardening medical instruments is determined for the case when there are no unirradiated sites on the surface under treatment. The increase in the light spot diameter during irradiation has been shown to be followed by more rapid expansion of the hardened area in comparison with the one of the tempered zone.

[Adenylate cyclase activity in human nasal polyps under conditions of stimulation of serotonin biosynthesis (in vitro)]. / Adenilattsiklaznaia aktivnost' polipov nosa cheloveka v usloviiakh stimuliatsii biosinteza serotonina (in vitro)

Nasal polyp tissue possess adenylatecyclase activity. Under conditions of incubation of nasal polyps with the use of reserpine (an activator of serotonin synthesis in this tissue) there can be observed a statistically significant increase of adenylatecyclase activity. During the first minutes of the polyp incubation with reserpine the activity of the enzyme rose ten-fold. Participation of the adenylatecyclase system at the initial stages of morphological and biochemical differentiation, accompanying serotonin biosynthesis in human nose polyps was confirmed.
