摘要： Proposed is a method for vascular embolization of the blood vessel of a patient by introducing an aqueous solution of a specific thermosensitive polymer, which is liquid at low temperatures but causes coagulation when heated up to the body temperature of the patient, into the blood vessel followed by in situ heating of the solution. The thermosensitive polymer found to be suitable for the purpose is a homopolymer or copolymer of an N-substituted (meth) acrylamide monomer having a specified intrinsic viscosity in tetrahydrofuran and gives an aqueous solution capable of exhibiting phase transition from a liquid to a coagulate at a transition temperature of 10.degree. to 37.degree..

摘要： The invention involves a sealed lead-acid battery comprising a cell element having positive plates, negative plates and separators, and electrolyte retained within micropore of the cell element.The micropores of both the plates is substantially filled with the electrolyte, while the micropores of the separators are not completely filled with the electrolyte.The voids formed partially in the micropores of the separators permit transport of the oxygen gas from the positive plates to the negative plates.Such a sealed lead-acid battery has long service life, and excels in ability to O.sub.2 absorb gases and reproduce water during overcharging and to recover by charging after a long overdischarged-state storage.
