Abstract: The present invention relates to a pharmaceutical composition for combined administration of melatonin and prostaglandin E2 (PGE2) for the treatment of intestinal epithelial injury diseases, and it is confirmed that when intestinal epithelial organoids are treated in combination with melatonin and PGE2, the expression of revival stem cell markers increases more than when the two substances are treated alone, and therefore it can be usefully used as a composition for preventing, treating or improving intestinal epithelial injury diseases.

Abstract: A vehicle fuel system includes a turbocharger having a compressor disposed on an intake line of an engine. The compressor selectively compresses intake air supplied to the engine. The fuel system has a canister configured to capture fuel vapor discharged from a fuel tank and a purge control valve configured to open or close the purge line depending on a pressure of the intake line. The fuel system has a check valve provided on the purge line that blocks movement of a fluid from the intake line to the canister. The fuel system has a controller performing control such that the purge control valve is operated in a closed mode to prevent intake air in the intake line from being introduced into the fuel tank when breakdown of the check valve is sensed during driving of the vehicle.
