Abstract
The behaviour of fishes to change their body colour in response to background colouration has long been known. Fish also display colourresponses during excitement and courtship. These spectacular changes are mediated through the activities of integumentary pigment containing cells called chromatophores. Across the animal kingdom, a large number of species rely on the colours and markings of their skin for purposes such as concealment and warning. The sophistication and control has reached astonishing levels in some animals (Naitoh et al.,1985). The ability to change skin colour and pattern is essential for survival in many species. In species such as the flatfish or the chameleon, the change occurs rapidly and are controlled by hormonal or nerve signals. The slowly evolving colour change occurs in response to continuous exposure to stimuli, as can be seen by prolonged exposure of skin to sunlight. A particularly striking example
occurs in members of the marine angelfish genus Pomacanthus. A number of diseases are attributed to defective pigmentation, including the condition vitiligo which affects approximately 1% of the population. This disease is a result of destruction of melanocytes and causes patches of white skin (McClure, 1998). Methoxsalen, which is used in the present investigation, belongs to furocoumarin group of organic chemical compounds and is a
very potent photosensitizing agent when combined with exposure to sunlight thereby, being very useful in the treatment of vitiligo.Â
