[Histonet] The Use of Plants in Histology Laboratories

[Mickley, Beth]

I found this great article about plants used in laboratories:

Plants That Can Clean Up Your Indoor Air

Plants clean indoor air in two ways—by absorbing contaminants through pores on the leaves, and by metabolizing contaminants through organisms living in the soil. In fact, plants are so effective that some stores, like Lowe’s and Home Depot, are starting to label the most effective ones with tags. 

Though it seems most plants will benefit indoor air, the following are those that have been shown in scientific studies and shown to work. These plants can also help maintain humidity levels and remove mold spores and bacteria from the air. 
1.Spider Plant: formaldehyde, xylene and toluene.
2.Golden Pothos: benzene, formaldehyde, trichloroethylene, xylene and toluene.
3.Snake Plant (Mother-in-Law’s Tongue): benzene, formaldehyde, trichloroethylene, xylene and toluene.
4.Bamboo Palm or Reed Palm: formaldehyde, xylene, and toluene.
5.Chinese Evergreen: benzene, formaldehyde.
6.Peace Lily: benzene, formaldehyde, trichloroethylene, xylene, toluene, and ammonia.
7.English Ivy: mold and mildew, formaldehyde, benzene, xylene, and toluene.
8.Gerbera Daisies: benzene, formaldehyde, trichloroethylene.
9.Red-Edged Dracaena (Dracaena Marginata): benzene, formaldehyde, trichloroethylene, xylene, and toluene. 
10.Warneck Dracaena: benzene, trichloroethylene, xylene, and toluene.
11.Weeping Fig: formaldehyde, xylene, and toluene.
12.Chrysanthemum: formaldehyde, benzene, trichloroethylene, xylene, toluene, and ammonia.
13.Boston fern: formaldehyde, xylene and toluene.
14.Philodendron: formaldehyde.

Hello all! Are there any labs out there using plants in their processing
rooms to reduce formaldehyde and xylene fumes? If so, please share how you
went about this and if there have been issues with contamination?

We didn't compare EDTA with formic acid. But heard that formic acid also
can do many IHC and ISH, if not all the antibodies and all probes. I always
have problem of bone falling off, no matter what kind of slides. Thinking
both PFA and EDTA affect on this issue. So trying frozen tape unfixed,
undecalcified bone now. If anyone has research paper regarding this, please
share.
Thanks.

With his permission I post pathologist Leon Metlay's Facebook obituary of
his wife's father:

My father-in-law, Dr. Bernard Leon Klionsky, died [November 11th, 2017] at
the age of 92. He was one of the unsung heroes of pathology. As a young
man, he invented the form of cryostat that we all use to this day, with the
microtome down inside the freezer. He was one of the greatest teachers I've
ever known. He was primarily known as a cytopathologist, but was also an
early member of the Pediatric Pathology Club.

As a child, during the Depression, he sold ice cream from a box on his
bicycle. He realized that the ice cream stayed cold with the opening on the
top. He applied that to cryostats. The paper was (I think) in AJCP. Some
time in the late '50s.

I asked him: What was his relationship to International / Damon / IEC (I
don't remember the exact name), that as far as I know brought out the first
practical refrigerated microtomes? I think they came along in 1960, and
were in common use by the time I got into pathology in 1964, though the old
"wet knife" method continued in common use into the 1970s.

He replied: He had no relationship with any manufacturer as far as I know.
As I heard it, he tried to put the idea in the public domain, so that
cryostats would be less expensive. I don't know what happened. The
University of Kansas got a free cryostat while he was there. When he moved
on to Pitt, the manufacturer took back the cryostat.

Does any of our old-timers remember any of this?
