125 years ago, a physiologist named Sidney Ringer discovered that a solution of saline prepared by his assistant seemed to keep excised rat hearts beating longer than normal saline.
It turns out this is because the assistant was a lazy slob and used London tap water instead of distilled. Good thing, too - the water, being hard, had a substantial amount of Ca2+, which we now appreciate is important in muscle function.
A derivative of the solution (invented only 50 years later) still lives on, Ringer's Lactate.

We like to think of boundaries as being clear-cut borders, but at least in the biological world they generally turn out to be fuzzy zones of change. The line between land and sea is my own favorite example. Last summer my wife and I would sometimes take our oldest daughter Charlotte to the beach.…
As long as I'm stranded in a snowstorm (thankfully fading right now) and unable to teach my human physiology class this morning, I thought I'd at least put a small part of the story I was going to tell on the web. We're currently talking about muscle physiology, and I've already gone over the…
It is literally very difficult to mend a broken heart. Despite its importance, the heart is notoriously bad at regenerating itself after injury. If it is damaged - say, by a heart attack - it replaces the lost muscle with scar tissue rather than fresh cells. That weakens it and increases the chance…
So why isn't it called [Assistant's Name]'s Solution?
I didn't know this and it's so amusing. I was searching for some info on Ringer's solution for my practical exams coming up. Great blog!
They would always mention this substance in the TV show Emergency! back in the '70's - good to know what iit is....
My cat gets lactated Ringers twice a week. I got that it contained lactate but never understood what was meant by Ringers. Now I know.
