Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biophysics and Physical Chemistry Candidate: Denisa Mazouchová Supervizor: Mgr. Monika Kuchařová, Ph.D. Title of diploma thesis: Effect of ultraviolet radiation on the change the mechanical parameters of human skin This diploma thesis deals in theoretical part with the properties of human skin, the characteristics of the UV radiation and its effects on human skin. The practical part of the thesis focuses on the in vivo measurement of mechanical parameters of human skin after UV radiation. Mechanical characteristics of human skin were measured in 12 subjects before the application of UV radiation, immediately after application of UV and after 24 hours of rest skin. The experiment used a UV lamp with a wavelength of 370 nm emitted light. The monitored parameters were Hooke's and Newton's coefficients. Hooke's coefficient gives us the stiffness of the skin as a whole , Newton coefficient characterises its viscosity. For measurement of those parameters was used dynamic viscoelastomer. The experiment has been found out that no signifiant ganges of Hooke's and Newton's coefficients were not found immediately after the application of UV radiation of wavelength 370 nm, in 12 volunteers. Significant change occurred only in the...
