Photodynamic Therapy Variation in Biological Activities of HPD and Biological Effectiveness with RIF-1
Photobiology applied to medicine is one of the oldest interests of men. Since ancient times, human beings have had a belief in the health giving properties of sunlight and its biological effects on all life on earth. Accordingly, heliotherapy (or sun exposure) was prescribed before any modern drugs for the treatment and prevention of cutaneous tuberculosis, rickets and maintaining sterility (i.e. killing germs); further evolution is shown in Figure 1.
