Welcome to HISTONET. This is an electronic mailing list for the exchange of
information pertaining to histotechnology and related fields.
PLEASE SAVE THIS MESSAGE.
It contains useful information about how to use the list and what to do if
experience problems. It also includes some basic rules for email etiquette
(Netiquette) which will be helpful to those who are new to this form of
WHAT IS A LISTSERVER?
A list server is a computer that runs software which will receive incoming
electronic mail (email) messages and reroute them automatically to everyone
the subscriber list. Email uses the vast expanse of the Internet to allow
almost instantaneous communication between networked computers around the
world. Our system uses the LISTSTAR software from Quarterdeck Corporation
(California) and can currently send about 30 messages a minute. With the
present number of subscribers, we are processing about 10,000 outbound
messages a day.
WHO SHOULD SUBSCRIBE?
Anyone interested in research or clinical applications of histology,
immunohistochemistry, in-situ hybridization pathology, and electron
may find Histonet informative and useful. Currently, there are more than 850
subscribers from all over the world. Subscribers include hospital employees
from major urban centers and obscure remote locales, university researchers,
botanists and the employees of commercial laboratories, government agencies,
veterinary facilities and a wide variety of commercial industrial ventures.
WHO RUNS HISTONET?
The list is run by Linda R. Margraf, M.D. and Herb K. Hagler, Ph.D. using
hardware and software owned by the University of Texas Southwestern Medical
School, Department of Pathology in Dallas, Texas. If you have any questions
problems with Histonet please contact Linda Margraf at
HOW DOES THE LIST WORK?
This server, unlike many systems, uses ONLY ONE ADDRESS to send commands to
the computer and to post messages. The server will recognize commands sent
the SUBJECT line of the message and only when they are spelled exactly as
listed below. Anything not identified as a command will be circulated to
EVERYONE on the list.
The following is a list of commands the server recognizes:
Your address will be added to the list of subscribers. You will then be
to send messages to this list that will be forwarded to all other list
subscribers. You will begin to receive all messages sent to the list by
Your address will be added to the list of subscribers who receive a digest
instead of each forwarded message. A digest is a compilation of all the
messages received in a 24 hour period. It is sent to the digest subscribers
every night after midnight. Digest subscribers can post and respond to
messages the same as "real-time" subscribers.
A list of available digests will be returned to you. Histonet stores old
messages as daily digests for approximately three months. To read previous
messages, copy the list of available digests, mark the dates of interest
return it to the server.
Your address will be removed from the list of subscribers.
You will no longer be able to send messages to the members
of the list.
A list of the commands recognized by the server will be returned to you.
WHAT ARE THE RULES?
You may post any questions you wish pertaining to histology, pathology,
in-situ hybridization, immunohistochemistry etc. Equipment and reagent
evaluations, laboratory management issues, government regulations, and job
opportunities are all appropriate topics. The University asks that we
the use of its hardware and software to business purposes only (occasional
jokes do slip through but PLEASE use restraint). Vendors and those with
commercial interests in histology products are welcome contributors however,
we ask that blatant advertisements be avoided at all times. It is fine to
refer to product that your company produces if it is pertinent to a topic
being discussed on the list. Unsolicited advertisements are poorly tolerated
by the members and you will likely receive a number of negative comments if
you overstep the boundaries. Please contact Linda Margraf at
LMargraf@childmed.dallas.tx.us if you are not sure about the appropriateness
if a message you wish to post.
BASIC HISTONET "NETIQUETTE"
It is most helpful to the list members if you post your responses to queries
to everyone on the list and not just as a personal reply to the person
the question. That way duplicate messages are minimized and we all learn
each other's comments.
Likewise, if you post a question and get a number of responses back directly
to you, it is helpful to everyone if you could send out a summary of the
replies you got to Histonet.
Please avoid abbreviations unless they are explained in your message. For
example: immunohistochemistry (IHC). This list circulates to a wide variety
individuals and what seems obvious to you may have no meaning on the other
side of the world.
Please sign your letter and include your institution or affiliation and
location. Not all email systems have headers which identify the sender.
Do use the subject line to indicate the topic of your message.
DON'T USE ONLY CAPITAL LETTERS -it is considered shouting.
Please send questions and problems about the list directly to Linda Margraf
LMargraf@childmed.dallas.tx.us and don't circulate them to the >850
subscribers on the list. Be careful when sending commands to the server to
the command in the SUBJECT LINE and spell it correctly.
Please do not send images as attachments with your message. We can now post
images at our web site (http://pathcuri1.swmed.edu). To have an image posted
send it to Herb Hagler at email@example.com.

Our xylene has been turning green recently....I have an idea as to what it
is...however my thoughts do not matter at this point......I will give you
the situation and ask for your advise.
1. The formalin is pretty clear[we do not handle many grossly bloody spec.]
2.The following alcohols are clear...
3.The xylene has a slight green tinge to it...occasionally a deeper
green..that looks like the counterstain of the gms.
4Occasionally the parrafin will take on the light green color also .
A coworker thinks this is a bilirubin effect...[fouts]that the
excess blood is being carried over to the xylene causing the xylene to turn
green.....she also states she thinks there is a backflow in our
processor..noting she thought the last 2 95% alcohols before the xylene were
clowdy when she dumped them....
I checked the alcohols today....they ran clear
2.The xylene was starting to look like it might have a tinge of green
3.I documented how many spec.I cut today that had been dyed in meth
blue..noting that the tissue when inked in this, turns light green to blue
green on completion of processing.
4.the formalin did not have that dirty rust color ..you know the one that is
brown and green and looks like swamp water!
All the rest of the reagents were clean...
I think...when the tissue goes thru the xylene..it pulls out
excess dye do to the vacume...[everyone knows you can take a swab of gauze
dip it in xylene and it will remove every so called permanent ink ever made
by man!]...I think that is where the color is coming from....] My coworker
says no....It is blood she knows this...She has told me she is smarter than
the average bear...she went to a very elite school...almost ivy league...and
she knows these things.....
So me..not as smart as the average bear...asks you...my fellow histotechs[ps
shes not certified]....If it is the bilirubin effect wouldnt it show up at
the begining of processing...shouldnt the formalins be swamp water [rusty
green]...long before the xylene?If it is blood why are all the reagent
clear?....Am I missing somthing? am usually open minded about these things
but lately i have been confronted with so much im not sure!!!!!!!!!!!1Send
your response to firstname.lastname@example.org or
email@example.com...................firstname.lastname@example.org will no longer be
available in two days....Please Please
