Help With Blending/placement

So my site's inner pages have one google ad block per page. example of this is here:
http://www.dogflu.ca/10042007/16/fish_good_for_pregnant_women

Before my redesign, my ctr was much higher than it is now, any ideas of different colours relating to blending that I can try to bring up my ctr? Thanks.

 

I would take the ad rectangle and place it directly in your content.

 

hmmmm i find that the ecpn is better where it is, but my ctr is lower. any idea on ways to make it more intising

 

anybody else??
