  • Patent number: 9522244
    Abstract: A brain cooling apparatus is provided that can circulate a fluid between a containing unit of a brain cooling device and the brain cooling apparatus while maintaining an appropriate pressure of the fluid in the containing unit, and a brain cooling device suitable thereto also is provided. A control device circulates a physiological saline solution between a storage tank and a cuff by driving a first pump in a direction in which the physiological saline solution flows toward the cuff, and driving a second pump in a direction in which the physiological saline solution flows toward the storage tank. In this state, the control device adjusts the rotation speed of at least the second pump, so that the pressure of the physiological saline solution in the cuff becomes a preset target pressure.

  • Publication number: 20160256566
    Abstract: In order to reduce the side effects of paclitaxel derivatives having excellent anti-cancer effects, an attempt was made to produce a liposome encapsulating paclitaxel derivatives such as paclitaxel monoglycosides and docetaxel monoglycosides. However, the introduction efficiency of paclitaxel derivatives, etc., into a liposome was poor, and this technique was not developed to a practical level. The present invention provides a method for producing a liposome encapsulating a paclitaxel monoglycoside and/or a docetaxel monoglycoside, and having an antibody specifically recognizing a cancer cell, the method comprising a step of bringing a liposome encapsulating a polyoxyethylene ester derivative, a lower alcohol, and a buffer or water into contact with a solution in which a paclitaxel monoglycoside and/or a docetaxel monoglycoside is dissolved in an alkylene glycol-containing buffer or water.
