Please format your code and show your erros. What are you trying to do with your loop, just display slices of your image set?
Why not just:
for iii = 1:10 %or however many slices there are
imshow(uint8(xy(:,:,:,iii)));
pause(0.5);
end

Well which is it: iii or jjj? Regardless, learn to use the debugger (so you can solve things quickly without waiting on us), set a breakpoint on the imshow() line, and then do this in the command window:
iii
jjj
size(xy)
min(xy(:))
max(xy(:))
Then, if you can't figure out what's wrong, come back here for help.
