To provide pellets, a molded article formed from the pellets, and a method for producing pellets. The Pellets contain: a thermoplastic resin; and a bundle of 2000 to 30000 rayon fibers arranged in parallel in the fiber length direction, wherein at least a portion of the thermoplastic resin is impregnated into the bundle of 2000 to 30000 rayon fibers, the thermoplastic resin has a melt flow rate (MFR) of 70 to 200 g/10 min when measured at a temperature of 230 C. and a load of 2.16 kg according to JIS K 7210, rayon fibers of the bundle have a number average fiber diameter of 5 to 30 m, and a number average length of the pellets is from 3 to 30 mm.

A urinary system catheter is covered by an ethanol extract of propolis on a surface of the urinary system catheter. The EEP is used as a coating material of the urinary system catheter to prepare an antimicrobial urinary system catheter. The EEP serving as a surface coating can enhance surface hydrophilicity of the urinary system catheter, and clinical operation of the urinary system catheter is facilitated. Meanwhile, the EEP serving as the surface coating can prevent a bacterial biofilm from being formed on the surface of the urinary system catheter, thereby possessing antimicrobial and anti-infective effects, and a high anti-scab capacity. In addition, propolis is a natural substance, has the advantages of good biocompatibility and low cost, and is suitable for mass production. The urinary system catheter prepared by using the EEP as the coating has a good application prospect.

Tissue and other body structures may be protected using a dry, free-flowing, sterilized mixture of chitosan particles and oxidized polysaccharide particles in sealed packaging. The mixture may assist in returning an injured, inflamed or surgically repaired surface to a normal state, e.g., through one or more healing mechanisms such as modulation of an inflammatory response, phagocytosis, mucosal remodeling, reciliation or other full or partial restoration of normal function.
