Photodynamic therapy (PDT)
Photodynamic therapy (PDT) is a comparatively novel therapeutic method involving a safe light source and a light-sensitive substance, termed as photosensitizers (PSs), such as methylene blue (MB), toluidine blue (TBO), sulfonated aluminum phthalocyanine, chlorine derivatives, nontoxic indocyanine green (ICG), and curcumin (CUR). (1) The combination of a nontoxic PS with low-intensity visible li...
متن کاملPhotodynamic Therapy (PDT): PDT Mechanisms
Photodynamic therapy (PDT) is a light based therapy used to ablate tumors. As practiced in oncology a photosensitizing agent is applied and then activated by a specific wavelength and energy of light. This light energy in the presence of oxygen will lead to the creation of the photodynamic reaction which is cyto and vasculo toxic. This paper will review the mechanisms of action of PDT and how t...
متن کاملAnimal models for photodynamic therapy (PDT).
Photodynamic therapy (PDT) employs non-toxic dyes called photosensitizers (PSs), which absorb visible light to give the excited singlet state, followed by the long-lived triplet state that can undergo photochemistry. In the presence of ambient oxygen, reactive oxygen species (ROS), such as singlet oxygen and hydroxyl radicals are formed that are able to kill cancer cells, inactivate microbial p...
متن کاملA method for video-assisted thoracoscopic photodynamic therapy (VAT-PDT).
A technique is described for application of photodynamic therapy (PDT) to peripheral pulmonary and other intrathoracic malignant tumours. For video-assisted thoracoscopic-PDT we advocate the use of the flexible fibreoptic bronchoscope through an appropriately placed port. This, together with the standard thoracoscope and attached monitor can provide three-dimensional visualisation of the intrat...
متن کاملHypericin-photodynamic therapy (PDT) using an alternative treatment regime suitable for multi-fraction PDT.
Photodynamic therapy (PDT) outcome depends on the conditions under which it is carried out. Maintaining the tumour tissue oxygen level is important for PDT efficacy and using a low fluence rate can improve outcome. In this work we studied the response of human nasopharyngeal carcinoma tumours in murine models to hypericin-PDT carried out under low fluence and fluence rate. A drug-light interval...
