摘要:
Donor material from a xenogeneic source is modified to enhance its survival time in a recipient by treating the donor material using low-dose photodynamic therapy (PDT). The donor material, such as an organ or cell suspension, is treated with a photosensitizer and irradiated in a low-dose protocol before transplantation into a xenogeneic recipient.
摘要:
A composition and method for inhibiting apoptosis, or decreasing the rate or extent of apoptosis, in target cells. The method comprises the step of the step of contacting the target cells with an apoptosis-regulating amount of at least one cysteine or serine protease inhibitor that: a. inhibits the conversion of the pro-enzyme form of CPP32 to its enzymatically-active form; b. blocks the proteolytic action of activated CPP32 against its cellular substrates; or c. both. The method is particularly applicable to ameliorating the side effects of, or enhancing the selectivity, of photodynamic therapy.
摘要:
Green porphyrins (Gp), compounds important in photodynamic therapy, have been associated with lipocomplexes to reduce the required amount of photosensitizer through higher effective absorption and increased specificity. BPDs, especially in conjunction with the HDL fraction of plasma lipoproteins, has been shown to be particularly effective in this context. Pharmaceutical compositions in which these combinations are the active ingredients for use in diagnosis and treatment of tumors are also disclosed.
摘要:
A general enhancement of the immune system of an animal can be obtained by administration of a T-cell suppressor factor which is idiotypic with regard to any specific antigen when such administration is made in the presence of an effective amount of adjuvant.
摘要:
This invention relates generally to the field of pharmacotherapeutics and the use of photodynamic therapy (“PDT”). In particular, the invention provides a method for reducing or preventing the effects of inflammation arising from normal dose photodynamic therapy (PDT), which method comprises exposing a target tissue in a subject that has been treated with normal dose PDT treatment to low dose light having a wavelength absorbed by a photosensitizing agent used in said normal dose PDT treatment for a time sufficient to reduce or prevent the effects of inflammation arising from said normal dose PDT treatment. The method is particularly useful in reducing or preventing the effects of inflammation arising from normal dose PDT treatment of ocular tissues.
摘要:
The present method involves the photodynamic treatment of hyperactive gland disorders. The method involves the topical administration of a photosensitizer composition comprising hydrophobic and/or lipophilic green porphyrins such as lemuteporfin, polyethylene glycol and skin penetration enhancers such as oleyl alcohol and TRANSCUTOL™ to affected skin and subsequent exposure of that skin to energy of a wavelength capable of activating the photosensitizer.
摘要:
Multiple sclerosis and rheumatoid arthritis can be treated effectively using photodynamic therapy. In this protocol, a photoactive compound is administered, allowed to distribute in the effected subject, and the subject is then irradiated to activate the photoactive compound. Alternatively, the blood of a subject to be treated can be subjected to PDT extracorporeally. In the case of rheumatoid arthritis, localized treatment at the joints may also be employed.
摘要:
Green porphyrins act as antigen-specific immunomodulators in the active phase of an immune response to a particular antigen. This effect occurs at ambient light levels.
摘要:
A method of administering photodynamic therapy begins with administering to an animal an effective amount of a photosensitizing agent which is less than about one half of the usual clinical dose for the photosensitizing agent. Then, following a post injection interval which is less about one quarter of the usual post injection interval, an effective dose of light which is less than about one half of the usual clinical dose of light used in conjunction with the photosensitizing agent is administered to the animal.
摘要:
Photodynamic therapy of conditions of the eye, especially those conditions characterized by unwanted neovasculature, such as age-related macular degeneration, results in enhanced visual acuity for treated subjects.
