But it's work only user logged in not when I use sudo.

Answer 1

Could you please explain better what are you trying to achieve? .profile is executed with a user privileges, when the user logs on.
So in order to use sudo in .profile you have to put user/group, user belongs to in /etc/sudoers

ok, sudo strips environment variables for various security reasons. In order to do what you want, you have to put in /etc/sudoers

Defaults        env_reset  
Defaults        env_keep += "MYVARIABLE YETANOTHER"
