Patent number: 7758894Abstract: Detoxified cobra venom and its constituent neurotoxins have been reported to have potent antiviral activity. Others have reported that snake venoms were generally immune stimulants.

Patent number: 5679350Abstract: A method of delivering a medicament to the surface of a cancer cell and transferring the medicament into the cancer cell using an activated plasminogen activator material such as a plasminogen activator inhibitor type-1 or type-2 (PAI-1, PAI-2). The medicament is coupled to PAI-1 or PAI-2 to form a reaction product that is coupled with the urokinase plasminogen activator (uPA) that is bound to the cell surface by the uPA receptor (uPAR). The medicament is coupled to PAI-1 or PAI-2 (for example, using a preserving agent such as saporin) in such a way that the medicament does not interfere with active sites responsible for binding to uPA or LRP proteins responsible for the internalization of the plasminogen activator material/conjugated medicament. The conjugated medicament prevents the conversion of the plasminogen activator inhibitor material into its latent inactive form. The resulting complex is internalized into the cancer cell to deliver the medicament within the cell.Type: GrantFiled: May 8, 1996Date of Patent: October 21, 1997Assignee: The University of ToledoInventors: Jerzy Jankun, Richard Hart

Patent number: 5562899Abstract: A common complication of vaginal delivery is the tearing of the muscles of the vagina and perineum. This tearing results in an irregular laceration which the surgeon must then repair. Current obstetrical practice is to prevent this irregular laceration by performing an episiotomy to create a regular laceration which is later sutured. However, both natural tearing of the vaginal and perineal muscles during delivery and surgical episiotomies are subject to further, more grave, complications. The use of medical therapy instead of surgical therapy will reduce the incidence of lacerations of the muscles of the vagina and perineum. The use of medical therapy for the relaxation of the muscles of the vagina and perineum is described.Type: GrantFiled: February 28, 1995Date of Patent: October 8, 1996Inventor: Allen Gerber

The basic amphipathic peptide binds to the cell membrane causing perturbation of the lipid bilayer. The non-covalent heterodimer complex dissociates and the phospholiphase A.sub.2 subunit (B) binds to the cell membrane. Subunit A acts as a chaperon preventing non-specific binding of the phospholipase A.sub.2, it has no enzymatic activity. The basic amphipathic peptide increases the effect of the phospholipase A.sub.2 subunit. Cell death is caused by the enzymatic hydrolysis of cell membrance phospholipids. Both the non-covalent heterodimer complex and the basic amphipathic peptide used were purified from the venoms of Crotalus durissus terrificus and Naja naja atra, respectively.Type: GrantFiled: July 23, 1991Date of Patent: August 3, 1993Assignee: Ventech Research Inc.Inventor: Juan C.

Patent number: 5178864Abstract: A therapeutically effective amount of soluble phospholipase A.sub.2 is administered into a subject for lowering the low density lipoproteins ("LDL") in the blood. Phospholipase A.sub.2 modifies the plasma LDL by hydrolyzing the phospholipids present in LDL. As a result, the modified LDL is rapidly removed from the bloodstream by the catabolic processes.Type: GrantFiled: August 14, 1990Date of Patent: January 12, 1993Assignee: MITInventors: Robert S. Lees, Robert S. Langer, Jr., Regine Labeque, Claudy J. P. Mullon
