To provide a lecithinized superoxide dismutase (PC-SOD) composition useful as a drug material and a process for its production. The PC-SOD composition contains a PC-SOD obtained by substituting at least amino group in a specific SOD with a lecithin moiety represented by the following formula (I), wherein the PC-SOD contains a PC-SOD (A) having an m number of amino groups substituted with the lecithin moieties (wherein m is an integer of from 1 to 4 and averages from 1.5 to 2.4 as a main component and the PC-SOD (A) consists of a PC-SOD (a1) wherein m=1, a PC-SOD (a2) wherein m=2, a PC-SOD (a3) wherein m=3 and a PC-SOD (a4) wherein m=4. 

Lecithinized superoxide dismutase composition and a process for its production

A cooling flow passage assembly consisting of pressure side cooling flow passages extending in a span direction and suction side cooling flow passages extending in the span direction and serially connected to the pressure side cooling flow passages is formed in a turbine blade. A cooling medium flows through the pressure side cooling flow passages in the direction toward the tip portion and through the suction side cooling flow passages in the direction toward the root. Cooling effect is improved by a Coriolis force. The number of the suction side cooling flow passages is larger than the number of the pressure side cooling flow passages. At least one of the suction side cooling flow passages forms at least one most downstream cooling flow passage. The cooling medium flows through the most downstream cooling flow passage and is exhausted outside of the turbine blade through nozzles, whereby the flow of the cooling medium through the most downstream cooling flow passage is speeded up.

A turbine cooling blade has a blade body defining an inner hollow portion, an insert core fitted into the inner hollow portion of the blade body with a space therebetween, and a plurality of projections formed on the insert core so as to project towards an inner surface of the blade body. The projections are formed with impingement holes through which cooling air flows from an inside of the insert core towards the space between the insert core and the blade body. The blade body is provided with a plurality of partitioning members partitioning the space into a plurality of sectioned chambers between the insert core and an inner surface of the blade body. The insert core member is formed with a number of impingement holes at portions other than the partitioning members, and the partitioning members extend in a span direction of the blade body. Cooling air flows from an inside of the insert core towards the chambers through the impingement holes, and the blade body is provided with a plurality of film cooling holes each penetrating the blade body from the chambers to an outer atmosphere side of the blade body and extending in a radial direction the blade body.
