We give some sufficient conditions for the Domnguez-Lorenzo condition in terms of the Jordan-von Neumann type constant, and the coefficient of weak orthogonality. As a consequence, we obtain some sufficient conditions for normal structure and fixed point theorems for multivalued nonexpansive mappings. These fixed point theorems improve some previous results in the recently papers.
