The white blood cell count plummets.

They attack like white blood cells fighting an infection.

Now, let me draw a plaque there. and we've been studying plaque since the video on heart attacks.

Elevated whiteblood cell count, lowgrade fever.

There's definitely an increased white blood count, with an absolute increase in lymphocytes having an atypical appearance.

It was terribly dangerous. (Laughter)

Leukemia cells treated with this compound turn into normal white blood cells.

When it ruptures, now it sudden i am doing a simplification of the process right over here.

Oh, and, uh, Dylan Simcoe's white count spiked to 19.

Um, the white blood cell count was normal, but there was a high level of the enzyme creatine kinase.

You're dead.

And the plaques, the material inside of them are lipids, so things like fat, cholesterol and also dead white blood cells, which is this kind of messy substance right over here.

Your blood count's dropping.

40 Watt incandescent lamp

100 Watt incandescent lamp

200 Watt incandescent lamp

But for the sake of demonstration ... I think we should turn on the lights.

Baseball is an interesting sport.

Part of the human immune system.

I don't know what to say exactly... but you've known all along how precarious this type of leukemia is.

It's a few cell layers thick. On the inside you have some red blood cells bumping along.

While we're waiting the analysis, let's get the blood count. So, place a small amount of blood on your slide.

To rule out fetal blood cells.

What's so interesting about baseball?

And so I placed one more element of each one of them.

And it doesn't have any mitochondria, no mitochondria.

Get me a CBC and tox screen.

Not very exciting.

End to end, that would form a line that would circle the earth twice.

Incidences of leukaemia, tuberculosis and meningitis have dropped considerably.

I'm just gonna kind of try to target a couple of the tissues that I think people sometimes might have questions about.

And it's in every cell.

What's so interesting about baseball?

Now, I have one last, two last little stories to tell you, in finishing off this business.

So that has no mitochondria, and it's not really using oxygen.

It's more fun to play baseball than to watch it.

He died from acute lymphoblastic leukemia.

He didn't recognize that at the time, and he contracted leukemia.

And, there are other frequently dividing cells in your body

And so they walk the Earth, feeding.

So you draw a little stick diagram like that and in the far left you'd put the number 5.

They found these red circular looking objects, and they looked, for all the world,

I have no way of taking his blood pressure or getting a blood count.

A red ball is mixed in with the white ones.

Presumably we'll ban them, but then we'll have the specter of teenagers in their high schools gyms routinely out performing the Olympic athletes.
