  • Patent number: 10500226
    Abstract: Compositions comprising an alginate, a source of sodium ions and a carrier (e.g., a pharmaceutically acceptable carrier), which are characterized by reduced association of the alginate chains and hence by at least one of: (i) a zeta potential weaker than ?25 mV, at a concentration of 0.5% (w/v) alginate in the carrier; and (ii) a diffusion coefficient of at least 10?8 cm2/second, at a concentration of 0.5% (w/v) alginate in the carrier, are disclosed. Also disclosed are uses of the composition and methods utilizing the composition for treating inflammatory bowel disease; liver damage, diseases and disorders, for treating a medical condition treatable by a hepatotoxic agent and for reducing or preventing liver damage, including liver damage caused by a hepatotoxic agent.

  • Patent number: 10328098
    Abstract: The present invention relates to methods for the treatment of hepatic disorders in a subject in need thereof. More specifically, the methods of the invention are based on the administration, preferably, systemic administration, of a therapeutically effective amount of at least one biocompatible alginate biomaterial, any modification thereof and any combination thereof. The invention further provides methods for sustaining serum albumin levels, and/or reducing serum AST and ALT, in subjects suffering from hepatic disorder. Still further, the invention provides methods for reducing apoptosis and inducing cell proliferation in a damaged liver tissue of a subject suffering of hepatic disorder, using the alginate biomaterial described by the invention.
