Abstract: | 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. |
