Abstract: Provided are a body temperature-responsive and non-reusable stiffness-varying intravenous (IV) needle with an on-site temperature sensing function, an IV infusion set having the same, and a manufacturing method thereof. The stiffness-varying IV needle may include a body member implemented in a hollow elongated shape through which drug passes and having a variable stiffness according to ambient temperature; and a coating member configured to cover the outer surface of the body member and having biocompatibility.

Abstract: The present invention relates to a method for improving drug metabolism function of human stem cell-derived hepatocytes. More precisely, the human stem cell-derived hepatocytes are similar in cell morphology to human hepatocytes but display reduced expressions of drug or alcohol metabolism associated enzymes and antioxidant enzymes. So, the inventors co-cultured the hepatocytes differentiated from human stem cells with mouse hepatic stellate cells. As a result, it was confirmed that alcohol mediated toxicity was reduced so that liver cell damage or apoptosis level was reduced. In the meantime, the expressions of drug and alcohol metabolism associated enzymes and antioxidant enzymes were increased.
