Refresh single asset

Basically, I need a **[AssetDatabase.Refresh][1]** but which refresh a single Asset. I'm editing an asset with an EditorWindow component, and to reflect the changes I'm calling **AssetDatabase.Refresh**, but it takes too long. Is there any way I can do the same thing as when you right-click an asset and then *Refresh*? [1]: http://docs.unity3d.com/Documentation/ScriptReference/AssetDatabase.Refresh.html
