OVERVIEW OF EXPERIENCES WITH PHOTODYNAMIC THERAPY FOR MALIGNANCY IN 192 PATIENTS

Abstract From April 1982 to April 1986 we used photodynamic therapy to treat 192 patients with various malignancies. In all, 172 injections of hematoporphyrin derivative and 135 injections of dihematoporphyrin ether were made intravenously to sensitize the tumors; 684 photodynamic treatments were given using a tunable dye argon laser system for the light source. The technical problems of the light source and delivery systems are presented and the efficacy of therapy is analyzed.     

Peculiar features of application of pH gradients formed in borate buffer with a polyhydroxy compound for separation of proteins in a free-flow electrophoretic apparatus

The use of pH gradients in borate buffer with a polyhydroxy compound for separation of proteins in a free-flow electrophoretic apparatus is outlined. The composition of the pH gradients, the free-flow apparatus design and its operation, and the main causes of failures in the protein separation are considered.

Photochemical reduction of organic electron acceptors in aqueous solutions

Conclusions The formation of OH radicals in the photoreduction of aqueous solutions of anthraquinonesulfonic acid as the result of electron transfer from water (OH^–) to a triplet molecule has been demonstrated.Translated from Izvestiya Akademii Nauk, Seriya Khimicheskaya, No. 11, pp. 2615–2617, November, 1969.
