[Histonet] von kossa

I did a von kossa day the other since it was sunny out and never thought to use a hema counterstain.  I will try that next time!  I use ammonia water too as a bluing agent.

Hi   Jan,
Thanks for your input! I have two A. S. degrees. One in veterinary nursing/technology and one in histology. And I have an AA where all my electives were biology,chemistry and micro. Then I'll have a BS in veterinary nursing/management. I'm starting a molecular program in January. So, I have a strong skills in courses you mentioned. I'm sure I want to do the R & D techniques but not so sure about the management!
The other thing about a histology career is learning how vast the field is. Did anyone ever have a counselor in their program that explained the different types of positions? I'm looking forward to attending the NSH convention in October. It will be my first one!
Carrie

Hello,
I work in a derm lab and we do all the grossing.  We hand write on all of our blocks and slides, so you can imagine we have mislabelings from time-to-time.  I was wondering if other labs have acceptable limits set for errors such as these, and if so what are they like? I am working on setting standards and corrective actions for errors in the lab.  Thank you for any input.

There is NO margin of error acceptable in mislabeling blocks or slides. I expect 100% compliance with this in my department. When you have like specimens all day like derm, you cannot make labeling errors.

There are no acceptable "standards" for mistakes. The present tendency of implementing the "6σ method" in the lab is to precisely eliminate mistakes, not to set an "acceptable" limit.

Hi Carrie,

The NSH convention in Alabama will also be my first.
It has only taken me 30 years to finally get to one.

Assuming I don't get lost I hope to see you all there (?turn right at
Honolulu, left at Los Angeles, then second exit on the left?)

I'll be the short tubby man with the funny accent.

I also run a derm lab where we gross and write cassettes. The doctors medical assistants make mistakes every week so I set up a double checking system where one tech accessions and check numbers and writes slides. Then I gross and make one final qc check.  this is only possible since I have low volume - not too sure about specific setups for larger lab qc

Hi, 

When doing a VonKossa stain in order to demonstrate calcium in tissue,
does it matter much if I use Mayer's hematoxylin instead of Ehrlich's
hematoxylin (which takes 6 months to ripen) ? 

Also, can I simply use homemade scott's tapwater for blueing instead of
using a lithium carbonate solution ? 

 

Thank you for your help,

Karine,

Either Hx will do, though I would not have used a haematoxylin since it
will lake with the calcium forming a blue stained deposit. I would
expect it to mask the silver of the von-kossa stain.

I would recommend 1% neutral red, ethylene green or even a light eosin
counterstain.
The silver "stained" calcium deposits should then stand out quite well.

What is your tissue of interest? Why not do the Von Kossa stain first  
and then counterstain with MacNeal's tetrachrome. This way you employ  
the use of a metachromatic stain for the rest of the tissue instead of  
just a nuclear staining hematoxylin.

Jack

Dear experts of histonet,

Given my formal background (chemistry synthesis) and current experience (cardiovascular research) my question may seem either too simple of not well directed. Please forgive my inexperience in these matters. 
 
In short, I am looking for a simple method that enhances the fluorescence of the cardio myofibers. 

In our institution, we have constructed a special setup allowing for investigation of vessel morphology. This is carried out by infusing a fluorescent plastic that polymerizes into an organ and then serially slicing the specimen while after each slice a high resolution image is taken of the remaining bulk material. As such, we can create high resolution 3D images of the vasculature, e.g. of a heart or kidney. 

Recently we have extended our setup (we are using a 16mpixel cooled camera which also allows very long exposure times) and are now trying to visualize the muscle fibers of the heart. For this we use a powerled (around 400nm) and image at around 600nm which seems to generates images that show autofluorescence of either collagen or muscle (I am unsure which this may be). Given these initial promising results, I would like to visualize the muscle fibers in more detail by using a staining protocol that would allow to stain post mortem hearts. I have gathered information so far that includes the use of ALA or Bouin's solution but there may be much better protocols suitable for this problem. 
I appreciate all feedback, thank you in advance,
