(sounds like the 2-year-old in training sales, doesn't it?)

24 hours after their breezes, 23 had evidence of microscopic bleeding down in the lung. 14 did not.

Now, they also found that the horses that bled? Had increased inflammation in the lung, and decreased immune response capability against bacteria and other particles that can get down in the lung. All at the microscopic level.

That's a respiratory infection waiting to happen.

That is a good reason why lasix should be permitted as a race day therapeutic medication.

Even in the 14 that didn't bleed? Did horses in the 70s and 80s have a rash of respiratory infections? I sure don't remember it. Do we even no if this microscopic bleeding causes poorer performance?
