The present invention teaches a marker useful for detection and measurement of free radical damage. Specifically, the invention takes advantage of alterations which occur to the N-terminus of the albumin molecule, a circulating protein in human blood, in the presence of free radicals. These alterations effect the ability of the N-terminus of the albumin molecule to bind metals. Methods for detecting and quantifying this alteration include evaluating and quantifying the cobalt binding capacity of...

Use of radiation-absorbing dyes (e.g., indocyanine green (ICG), fluorescein, rose bengal) and photodynamic dyes (e.g., hematoporphyrins, aminolevulinic acids, porphyrins, merocyanines, porphycenes, porfimer sodium, verteporfin, Photofrin II, PH-10, chlorins, zinc phthalocyanine, purpurins, pheophorbides, monoclonal antibody-dye conjugates of any of the foregoing dyes) for the treatment of conditions associated with abnormal vasculature, including, generally, lesions, and, more specifically, tumo...

A storage stable porfimer sodium (polyhematoporphyrin ether/ester) composition useful in the photodynamic therapy of cancer and other conditions is provided. The composition is characterized in that the percentage of ester linked porphyrin oligomers is less than 10% of the composition. Improved processes for preparing such compositions are also provided wherein acetylated hematoporphyrin is treated with alkali for sufficient time and temperature to reduce the amount of porphyrin oligomers joined...
