Patent number: 4683889Abstract: A method and system are disclosed for externally treating human blood, with the objective of reducing the functioning lymphocyte population in the blood system of a human subject. According to the method, blood is withdrawn from the subject and passed through an ultraviolet radiation field in the presence of a dissolved photoactive agent capable of forming photo-adducts with lymphocytic-DNA, mobile hormonal hormonal receptors or antigen sites to thereby effect covalent bonding between the photoactive agent and the same, thereby inhibiting the metabolic processes of the lymphocytes or complexing them; and thereupon returning the irradiated blood to the subject. The withdrawn blood may be formed into an extracorporeal stream and flowed through a treatment station whereat the irradiation is effected, as for example by exposure to UV radiation; and such flow process may be conducted on a continuous basis.Type: GrantFiled: June 21, 1985Date of Patent: August 4, 1987Assignees: Frederic A. Bourke, Jr., Eleanor F. Bourke, Richard L. Edelson, The Edelson TrustInventor: Richard L. Edelson

Patent number: 4684521Abstract: A chemical agent is disclosed which is useful for reducing the population of a selected blood constituent having receptor sites. The chemical agent includes a carrier having a strong affinity for the receptor sites on the blood constituent and a photoactive agent physically incorporated within or chemically bound to the carrier moiety which interferes with the metabolism of the selected blood constituent when activated by UV radiation. The photoactive agent may be a photocytotoxin selected from the group consisting of psoralen, pyrene, cholesteryloleate, acridine, porphyrin, fluorescein, rhodamine, 16-diazocortisone, ethidium, transistion metal complexes of bleomycin, transition metal complexes of deglycobleomycin and organoplatinum complexes.Type: GrantFiled: June 21, 1985Date of Patent: August 4, 1987Assignees: Frederic A.

Patent number: 4464166Abstract: A method and system are disclosed for externally treating human blood, with the objective of reducing the functioning lymphocyte population in the blood system of a human subject. According to the method, blood is withdrawn from the subject and passed throught an ultraviolet radiation field in the presence of from about 1 nanogram to 100 micrograms per ml of blood, of a dissolved photoactive agent capable of forming photo-adducts with lymphocytic-DNA, mobile cortisone receptors or antigen sites to thereby effect covalent bonding between the photoactive agent and the same, thereby inhibiting the metabolic processes of the lymphocytes or complexing them; and thereupon returning the irradiated blood to the subject. The withdrawn blood may be formed into an extracorporeal stream and flowed through a treatment station whereat the irradiation is effected, as for example by exposure to UV radiation; and such flow process may be conducted on a continuous basis.Type: GrantFiled: June 30, 1983Date of Patent: August 7, 1984Assignees: Frederic A.
