Subject: Do any elements besides sodium cause hypertension in a cell?

We have just finished a chapter on hypotension and hypertension in our 
biology class. We learned that hypertension occures when the concentration 
of a disolved substance is higher outside of the cell.  THe water diffuses 
out of the cell, causing it to shrink, and you get thirsty b/c you need to 
rehydrate.  The main example was sodium. I was wondering if any other 
elements had the same effect of making you thirsty as sodium.  Thank you 
for your time.
