A pharmaceutical composition for parenteral administration, including a water-soluble substance conjugate of curcumin as an active component.

Abstract: A liquid micrometer which includes: a liquid flow path which supplies liquid from a liquid supply device to a discharge nozzle; a flow rate sensor provided in the liquid flow path; a control valve provided in the liquid flow path between the liquid supply device and the flow rate sensor; a controller which controls the control valve such that a flow rate measured by the flow rate sensor becomes equal to a set value; a pressure sensor which measures pressure of the liquid injected from the discharge nozzle; and a calculating section which calculates the size of a work from the pressure measured by the pressure sensor in a state where the flow rate is maintained at the set value by the controller.

Abstract: A liquid micrometer of the present invention includes: a liquid flow path 30 which supplies liquid from liquid supply means 10 to a discharge nozzle 20; a flow rate sensor 40 provided in the liquid flow path 30; a control valve 50 provided in the liquid flow path 30 between the liquid supply means 10 and the flow rate sensor 40; a controller 60 which controls the control valve 50 such that a flow rate measured by the flow rate sensor 40 becomes equal to a set value; a pressure sensor 70 which measures pressure of the liquid injected from the discharge nozzle 20; and a calculating section 80 which calculates the size of a work A from the pressure measured by the pressure sensor 70 in a state where the flow rate is maintained at the set value by the controller.
