We donot have any language pack for Photoshop. However, i have an alternate for you which is only applicable if you have the latest version of PS i.e. CS6
So, You need to get the language swap done for your PS CS6 from Russian to English. Check this link for more details : http://helpx.adobe.com/x-productkb/policy-pricing/order-product-platform-language-swap.htm l
Hope that Helps.
