Hey, Dr Bernard here. This case was recorded inÂ
October 1841. It was published in a book in 1908.  Humans react to chemicals the sameÂ
way today, as they did back then.  Parts of I’ve adapted for today, butÂ
I’ve preserved as much of the original  description as possible. The poisoningÂ
still happens today, in a working space  that didn’t exist in the 1800s, all of which,Â
I will tell you about later in this video. A Scientist Inhaled 3 Liters of Gas he made inÂ
a balloon. This Is what happened to his kidneys. MB is a 31 year old man, presenting to theÂ
emergency room with a pain between his legs.  He tells the admitting nurseÂ
that over the last four hours,  he kept emptying his stomach intoÂ
the laboratory sink. At first,  it was forcefully projectile, but as theÂ
time continued, it became green in color. MB was a scientist writing a book about chemicals.  He had a good career and aÂ
good reputation as a teacher. MB loved to make jokes in the lab. Science isÂ
supposed to be fun, he thought. He would make  gases from chemical reactions and inhale them.Â
This would change his voice for a short amount  of time. All of his students found thisÂ
hilarious. His voice could become high,  his voice could become low. HeÂ
found this effect funny. And  he kept thinking of new ways to inhaleÂ
different gases, to “find his voice.” One day, MB mixed some metal shavings withÂ
sulfuric acid. He collected the resulting hydrogen  gas in a ballon, knowing that it would make hisÂ
voice an exceptionally high pitch, and because  this gas is light, it would just make its way outÂ
of his lungs, and it’ll be no problem he thought. Immediately after inhaling what wasÂ
supposed to be hydrogen gas in the balloon,  MB felt light like a feather. His voice wasÂ
high pitched and he could hear the resonance  ring throughout his skull as he felt like he wasÂ
floating around in the air. Looking at the ballon,  he saw there was enough for one more, as heÂ
breathed it in, and he felt on top of the  world. He was seized with giddiness and his visionÂ
felt lightweight, as it started turning dark. But  then he started to notice that he was shiveringÂ
and shaking. At first it was subtle, but then he  noticed that his legs started to hurt. The painÂ
got worse and worse as he could start to feel his  heart beating in his feet, as his hands startedÂ
tingling and going numb. He went into the bathroom  and noticed that his urine could only trickleÂ
out, and what did come out was a deep red color. As the hours passed, contents from MB’sÂ
stomach kept coming up. It was projectile  before it became green and it brought him downÂ
to the floor. He struggled to call for 911,  and he’s brought to theÂ
emergency room where we are now. At examination, the medical team noticed that MB’sÂ
skin felt cold to the touch, his heart rate was  high and his stomach contents that came up wereÂ
green, maybe a little yellow. When he could talk,  his voice seemed weak. His face and the whitesÂ
of his eyes were also a greenish-yellow color  meaning he’s jaundiced. The color comesÂ
from a chemical called bilirubin something  that makes feces brown and is produced fromÂ
breaking down red blood cells in the liver,  all of this meaning that there could be someÂ
liver damage happening to MB. He told them  about the hydrogen gas that he inhaled before thisÂ
happened, but he was unsure if it really was the  gas causing all these problems becauseÂ
hydrogen doesn’t just do something like this. As the night continued, theÂ
team noted that every hour,  on the hour, MB would have a stomach movementÂ
come up out his mouth. They noticed that his  urine was still red. But as the hours passed,Â
they noticed t hat MB stops urinating. He seems  bloated. His face and his belly are swollen asÂ
if he’s retaining the fluid that should be urine. A blood test finds that MB has anemia. An-Â
meaning without and -emia meaning presence of  blood. Something called hemoglobin was low inÂ
his blood, which is the protein that carries  oxygen throughout the body. Without oxygenÂ
going to vital parts like the brain,  bad things can start to happen.Â
But examining his red urine,  they find that what’s making itÂ
red is huge amounts of hemoglobin. Clearly, something is happening toÂ
his liver if he appears jaundiced.  And if he had hemoglobinuria before heÂ
completely stopped making urine altogether,  then it means something happened to his kidneysÂ
too, but why? MB inhaled what should have been  hydrogen gas. Typically you don’t get sickÂ
like this just by breathing that in, but  everything started to go wrong after thatÂ
particular moment. If he inhaled something,  then why are bad things happening toÂ
his liver and kidneys and not his lungs? In the lungs, the oxygen from the air, isÂ
exchanged for carbon dioxide from the blood.  If inhaled gas from the lungs goes directlyÂ
into the blood, and MB noticed blood in his  urine before he presented to the emergencyÂ
room, then it means that gas may have done  something to his blood. That “bad blood” couldÂ
have flown into his kidneys and become his urine,  and this gives the medical teamÂ
some clues as to what’s happening. As the days pass, MB’s vomiting episodes becomeÂ
less frequent. His jaundice disappeared. It  looked like he was getting better. But thenÂ
doctors noticed that he was bloated like he  was holding on to water. They noticed thatÂ
he hadn’t urinated for several days now.  When they inserted a catheter in to his bladderÂ
to drain it hoping there’d be a bunch of urine  in there, they find that it’s completelyÂ
empty. MB’s kidneys have completely stopped  working. But he didn’t appear to have anythingÂ
wrong with his brain. He could respond to  commands, he could hold conversation, he knewÂ
where he was, but as the fifth day of being  in the hospital continued, he started to becomeÂ
drowsy, and tired. There could be something wrong  with his brain, but that’s not likely given heÂ
could speak, and move. But all of that could mean  that not enough oxygen might be gettingÂ
to his brain for some reason, bringing  us back to his anemia, his hemoglobinuria,Â
and the idea of gas exchange in the lungs. Analysis of the metal shavings and the sulfuricÂ
acid that MB used to create the hydrogen gas  that he packed into his lungs finds substantialÂ
contamination of the element arsenic. If the  mixture reacted to form gas, then it meansÂ
that the “hydrogen” MB thought he inhaled,  was arsine. This toxic gas exchanged in his lungsÂ
and started pushing into his blood. It started  spreading everywhere all throughout his body,Â
and this explains everything happening to him.
 Air that we breathe in is not mostly oxygen,Â
it’s almost 80% nitrogen. On the periodic table,  nitrogen is a light element, it’s one ofÂ
the most abundant elements in living beings,  it’s mostly a gas on earth, but when it’s combinedÂ
with hydrogen, it becomes ammonia. In a column,  known as a group, on the table, elements haveÂ
similar features. They’re not exactly the same  because as you go down the column, elements getÂ
heavier. They become more unstable, meaning they  could be more reactive. If Nitrogen and hydrogenÂ
make up ammonia, then phosphorous, which is also  abundant in the body can combine with hydrogenÂ
and make Phosphine, which is a poison gas that  can cause spontaneous human combustion when inÂ
the body. This also means arsenic can combine with  hydrogen to make Arsine, which is what MB inhaledÂ
when he produced the gas in his balloon from  contaminated reagents. These chemical propertiesÂ
don’t tell us directly how and why bad things  happen when someone inhales arsine gas. It’sÂ
not immediately obvious and experiments haven’t  given us a better idea at the moment. But we doÂ
know WHAT happens, because it’s happening to MB. In the blood cells, arsine weakensÂ
the globin chains holding down heme.  We know this because this only happensÂ
to regular hemoglobin that’s found in  all healthy humans. It doesn’t happen toÂ
hemoglobin exposed to carbon monoxide,  the chemical known to bind stronger to hemoglobinÂ
than oxygen and can cause someone to suffocate  when it’s present. Arsine strips out the hemeÂ
in regular hemoglobin of a red blood cell,  and sends the heme to float around in the body andÂ
this is one part of where the problems come from. Heme contains iron. The form of iron that arsineÂ
strips out is reactive. It can cause damage to  all different parts of the body. One of the placesÂ
in the body that can’t handle this reactive iron  is the kidneys. The heme lodges into theÂ
tubules and this pigment causes oxidative damage  necrosis as the tissue dies. In MB, this is whatÂ
happened to him because he started urinating a red  color. It explains his anemia because theÂ
hemoglobin was getting cut out by arsine. And it  explains the hemoglobin in the urine beforeÂ
his kidneys completely stopped working  and he no longer made any urine forÂ
days while he was in the hospital. The idea of poison arsenic goes back toÂ
ancient times. It was used as a pesticide,  and the Romans knew it as the King of Poisons,Â
it was a poison of Kings because it was an  untraceable way to get rid of someone. EnglishÂ
sources say that the French at one point  knew arsenic as the Powder of Inheritance,Â
where it was used in untraceable deaths of  the elderly. “I totally have no idea whatÂ
happened to them, they just got sick from  the food!” would be brought up to insurers,Â
and wealth and an estate would be passed on. But while the ancient world knew arsenic asÂ
a poison, it also knew it as a medicine. In  Han Dynasty China 2000 years ago, a publishedÂ
book titled the Shennong Bencao Jing 神農本草經 is  an ancient pharmacopoeia, still availableÂ
in print today. It recorded the use of an  arsenic compound to treat jaundice, ulcers,Â
parasitic infections and malignant growths. What’s poison becomes medicine, and what’s oldÂ
becomes new again, bringing us to today. In 1971,  in Harbin city in the north of China,Â
the local government caught wind of an  herbalist dispensing cancer treatments.Â
They sent an official to inspect  what exactly these treatments were and theyÂ
discovered it was a mix of toad extract,  mercuric oxide, and arsenic trioxide. This mixtureÂ
was tested in a particular blood cancer called  Acute Promyelocytic Leukemia. Promyelocyte beingÂ
a young, immature type of blood cell. Leuk from  Greek Leukos meaning white referring to the kindÂ
of blood cell and -emia meaning presence in blood.  Immature white blood cell presence in blood. ThisÂ
appears in the body as a cancer. Arsenic trioxide  was used to achieve complete remission in 21 outÂ
of 32 patients with this particular blood cancer,  published in Chinese medical literature in 1992Â
with study rational deriving from a fusion of  traditional and modern medical ideas. TheÂ
idea of arsenic as a treatment for Acute  Promyelocytic Leukemia crossed over from China toÂ
one of the largest cancer centers in the United  States, Memorial Sloan Kettering. And published inÂ
English literature in 1998, 11 of 12 patients with  Acute Promyelocytic Leukemia were in remissionÂ
after treatment containing, Arsenic Trioxide. Today, we see this in the news. American FootballÂ
player playing for the Houston Texans was recently  diagnosed with Acute Promyelocytic Leukemia,Â
his treatment may contain therapeutic arsenic as  it is a standard of care. SemiconductorÂ
manufacturing to make computer chips relies  on a step that needs ion implantation, whereÂ
a gas is used to implant a metal on the wafer,  and it’s here where arsenic is depositedÂ
on chips through the use of Arsine gas,  as it’s used today. This is an occupationalÂ
hazard for people working in this space  that happens today, in a workspace that didn’tÂ
exist in the 1800s, bringing us back to MB. On his 6th day in the hospital, MB passed 7Â
stools that were likely a watery consistency  consistent with arsenic poisoning. The medicalÂ
team found that he did make some urine,  but all of it was red. As the day passed, heÂ
became weak and bloated as the sun started set. Arsine gas was discovered in 1775. The firstÂ
recorded case of poisoning was in 1815 in Germany,  where the chemist accidentally exposed himself toÂ
the gas. These accidents would happen around the  time the hot air balloon was invented, becauseÂ
to inflate the balloon with hydrogen gas,  sulfuric acid was mixed with iron, andÂ
because both would be contaminated with  arsenic, people exposed would suffer illnessÂ
and be found not alive days later, just like MB. At autopsy, doctors tested MB’s body fluids. TheyÂ
found the same concentration of arsenic that was  found in the sulfuric acid, and the metal shavingsÂ
that he used to make the gas that he inhaled. The test that doctors used to find theÂ
arsenic in MB is the same test that put a  stop to the French calling arsenic the powderÂ
of inheritance, because it’s easily provable  once the arsenic can be detected. But asÂ
sophisticated as doctors were at the time  to detect arsenic after the fact, they didn’tÂ
know how to treat arsine gas poisoning back then. Today, we can try to stop the kidney damage fromÂ
arsine by exchange transfusion. This will take  out the patient’s broken blood, and replaceÂ
it with donor blood that doesn’t have arsenic  in it. Today, Sulfuric acid doesn’t, shouldn’t,Â
have arsenic contamination in it, iron still does  sometimes. In everyday life, regular people aren’tÂ
typically going to come into abundant contact with  arsenic and arsine gas. General rule of thumbÂ
in line with MB’s case, if you don’t need to put  it in your lungs, don’t put it in your lungs. IfÂ
recognized early and if the arsine exposure wasn’t  too much, patients can come out OK. For MB, givenÂ
that he was alive 6 more days in the hospital  after he accidentally inhaled that 3 liters ofÂ
Arsine gas, he could have been saved if his case  happened today, but they didn’t know how or haveÂ
the tools to do so back then on October 23, 1841. Thanks so much for watching. TakeÂ
care of yourself and be well.
Class, I snorted a ballon full of poisonous gas and I'm starting to feel the effects hahahahahaha... man.
And he would make a full recovery
