[Solution] A bent product (10) that is formed by bending an integrally extrusion-formed body and has: a metal core material (20) provided with a tube-shaped peripheral wall (21) and a first partition wall (23) that extends in the longitudinal direction of the tube shape and divides the inner space of the peripheral wall in the direction of the major axis of the cross section perpendicular to the longitudinal direction of the tube shape; and a covering layer (40) that is formed on the outer surface of the core material and contains at least a thermoplastic resin. The thickness (t) of the peripheral wall is 0.8-2.3mm, and a reinforcing means is provided to the inner space side of the peripheral wall at a section (25) thereof to the inside of the bend.

A method for producing a coated sheet which involves an application step of applying a fluid containing a resin material and a solvent on a traveling base film continuously, and a drying step of drying a coating film applied on the base film in the above application step, wherein the above application fluid has a viscosity of 70 to 8,000 mPa sec, and the fluctuation rate for the speed of the traveling of the above base film is controlled to 3.0 % or less. The above method can be suitably employed for forming a coating film being free from the failure in its appearance and having a uniform thickness.

The invention provides a heatproof lyoprotectant for a live vaccine against pseudorabies. The heatproof lyoprotectant comprises, by weight, 3 to 10 parts of gelatin, 1 to 5 parts of trehalose, 5 to 15 parts of sucrose, 0.1 to 2 parts bovine serum albumin, 1 to 8 parts of tryptone, 2 to 10 parts of enzyme-hydrolyzed casein, 1 to 5 parts of thiourea, 0.8 to 2 parts of L-monosodium glutamate, 0.1 to 3 parts of arginine, 0.5 to 5 parts of polyvinylpyrrolidone (PVP-K30) and 0.1 to 2 parts of mannitol. The invention also discloses a preparation method of the heatproof lyoprotectant and a lyophilized vaccine prepared from the heatproof lyoprotectant. When the heatproof lyoprotectant is used for protecting the vaccine and a specific lyophilization process is employed, lyophilization loss of viruses can be effectively reduced, the temperature tolerance of the viruses can be improved, and the vaccine can still maintain good physical properties and titer after long-term storage; i.e., the vaccine has stable characters and has the characteristics of heat resistance and long storage time.

The invention discloses a freezing-drying method for live vaccine. The freezing-drying method comprises the steps that the eutectic point range of a to-be-frozen and to-be-dried vaccine is tested, then, the live vaccine is placed in a vacuum freezing-drying machine pre-cooled to 0+ / -1 DEG C, when the temperature of a plate layer of the vacuum freezing-drying machine is reduced to be higher than the eutectic point of the live vaccine by 1-2 DEG C, the current state is kept for 1-2 h, and continuous cooling is conducted with the rate of 1 DEG C / h till all vaccine is frozen; and cooling is immediately conducted to the temperature needed for sublimation, and finally vacuum sublimation is conducted according to the normal procedure. The product obtained through the method is not provided with large ice crystals, sublimation is easy, and after freezing-drying, a good product physical behavior can be obtained, and the freezing-drying titer losses are minimal.
