Unexpected distribution of surface hydration level of the lip.

BACKGROUND: The functional properties of human lips depend on their hydration level. Limited data are, however, available. OBJECTIVE: To investigate water distribution through the lower lip surface. METHODS: Images from the surface of the lip were recorded using a new capacitance imaging technique. Capacitance and conductance measurements were also carried out in various points of lower lip and on adjacent skin. RESULTS: Data clearly show that the closest part of the mucosa of the lip is less hydrated than the external part. These unexpected findings could be related to the presence of a premucosa area whose structure is clearly different from that of vermilion zone.

Commercial inactivated culture polyvaccine against herpes simplex viruses (types 1 and 2) developed at D. I. Ivanovsky Institute of Virology promoted cessation of viremia. During the first vaccination viremia coincided with appearance of a focal allergic test on the retina, which is proposed for the diagnosis of herpetic involvement of the posterior compartment of the eye. T-cellular immunity normalized after a course of vaccination. Experimental immunization of rats and vaccination of patients with chronic ophthalmic and genital herpes demonstrated the therapeutic activity of inactivated herpetic polyvaccine in suppositoria.
