And other crazy stuff. RE: [Histonet] cutting honey bees

[Roberta Horner]

The oddest things I cut were the honey bee and yellow jacket stingers.  I've done plant stamen, reptiles, fish and I believe another insect.  I usually tell the students that are working on a research project to give me a sample they don't care about so I can see if I can do what they want.

But I had oddities that I didn't have to section like during hunting season a hunter killed a deer and there was a mass on the trachea that he wanted tested to make sure the deer was okay to eat.  I got the sample and when I tried to gross it I found a very hard shiny silver object.  I told the pathologist whose case it was that the mass was from a bullet did he still want histo done. No.

The other interesting one was the egg shell.
The conversation went something like this.
Pathologist:  Can you section this egg shell
Me: No it's too hard.
P: Can't you decal it
M: That's not going to work.
P: Did you try.
M: No
P: Don't you think you should try first.
M: Okay fine but it is no going to work.

Put a piece of eggshell (made of calcium) into some decal solution (that removes calcium) and watch the egg shell bubble and disappear.  I did get to tell the pathologist "I told you so"

You crazy research people...OK, so what is the craziest thing you ever had to cut, or were asked to cut?

For me, not too bad, but embedding for EM and sectioning a single oocyte that was nearly microscopic. I'll just say it took a LOT of thick sections too face down to it without actually cutting through it.


Open the floodgates....

for the whole bee I probably would process and embed it in glycol methacrylate (gma) it is much harder and would give better sections, we have done zebra fish and several other harder tissues including calcified bone in GMA.

> I sectioned and stained honey bee and yellow jacket stingers years ago.  They wanted to show the difference between the stingers.  I wasn't sure what to do so I processed and handled like everything else.  I was able to get some good sections.  I put 6 stingers in each block and cut several sections figuring there should be at least one good stinger in each block and it worked.
