Methods and compositions for treating mammalian nerve tissue injuries
First Claim
1. A method for treating a mammalian patient having suffered an injury to nerve tissue of the central nervous system, the method comprisingadministering an effective amount of a composition comprising an amphipathic polymer comprising a polar substructure and a non-polar substructure to the mammalian patient, wherein the administering is effected after the injury occurs via the mammalian patient'"'"'s vascular system, wherein the administration is effective in delivering the amphipathic polymer to the site of the injured nerve tissue in the mammalian patient'"'"'s central nervous system, wherein delivery is effected using a technique selected from the group consisting of intravascular, intramuscular, subcutaneous and intraperitoneal injection and wherein the effective amount is an amount that increases the conduction of action potentials in injured nerve tissue of the central nervous system and increases at least one of reflex behavior, motor function and sensation in the patient.

Abstract
To achieve, an in vivo repair of injured mammalian nerve tissue, an effective amount of a biomembrane fusion agent is administered to the injured nerve tissue. The application of the biomembrane fusion agent may be performed by directly contacting the agent with the nerve tissue at the site of the injury. Alternatively, the biomembrane fusion agent is delivered to the site of the injury through the blood supply after administration of the biomembrane fusion agent to the patient. The administration is preferably by parenteral administration including including intravascular, intramuscular, subcutaneous, or intraperitoneal injection of an effective quantity of the biomembrane fusion agent so that an effective amount is delivered to the site of the nerve tissue injury.

16. A method for treating a mammalian patient having suffered an injury to nerve tissue of the central nervous system, the method comprising
administering an effective amount of a composition comprising a poloxamer or a poloxamine to the patient, wherein the poloxamer or poloxamine is delivered via the patient'"'"'s vascular system to a site of the injured nerve tissue of the mammalian patient'"'"'s central nervous system, wherein delivery of the effective amount of the composition is effected after the injury occurs using a technique selected from the group consisting of intravascular, intramuscular, subcutaneous and intraperitoneal injection, and wherein the effective amount is an amount that increases the conduction of action potentials in the central nervous system and increases at least one of reflex behavior, motor function and sensation in the patient.
- 18. A method for treating a mammalian patient having suffered an injury to nerve tissue of the central nervous system, the method comprising administering an effective amount of a composition comprising an amphipathic polymer comprising a polar substructure and a non-polar substructure wherein the administrating is effective in delivering the effective amount to a site of nerve tissue injury in the mammalian patient'"'"'s central nervous system by way of a vascular route, and wherein the effective amount is administered after the injury occurs and is an amount that increases the conduction of action potentials in injured nerve tissue and increases at least one of reflex behavior, motor function and sensation in the patient.
