> Hyernatremia and hyperchloremia:  what is it and what are the  
> possible effects?

Hypernatremia:  Levels of sodium in the blood are too high.

Hyperchloremia:  Levels of chloride in the blood are too high.

Possible effects?  Fluids are osmotically pulled out of other tissues to try to 
dilute the blood that contains the excesses of sodium and chloride, which can 
lead to serious central nervous system problems (such as happened to Bev Gray's 
horse in Dubai when she was forced by the management of our USA squad there to 
change her e-lyte protocol), digestive problems (messing up the ability of the 
cells in the GI tract to transport fluids--think ruptured stomachs, which we 
are seeing in the sport with increasing regularity), muscle issues (drawing 
fluid away from muscle causes local dehydration, which could lead to tying up), 
etc.  Bottom line is that other tissues become "dehydrated" despite the fact 
that the horse tries to drink more, because the horse can't get enough of the 
e-lytes out of the bloodstream fast enough.

This finding comes as no surprise to those who have been sufficiently observant 
to see the trends toward increasing problems in some of the horses subjected to 
high e-lyte dosing over the past few years.  It is always nice when science 
starts to look at such problems and begins to find the underlying reasons.
