- I recently came across a leaflet printed by PETA.
- In bold type on the front it read:
-
- Their jaws clenched, reacting to the pain.
- Cats were injected with embalming fluid while still alive
-
- On the back: in bold type: unattributed quote
-
- "I watched as L cut open the rat. Blood was spraying out. He
- smiled and told me, 'It's still alive. The heart's pumping blood.'
- The rat was then hooked up to a formaldehyde tube. His legs were
- kicking."
-
- It sounds to me like this L character is quite the sadist. What cruelty!
- What inhumanity!
-
- I don't think so. What their describing here is a standard lab. procedure
- called perfusing or "fixing" an animal. What they conveniently forget to
- tell you is the entire procedure.
-
- First of all the animal is given near lethal doses of anesthetics
- (usually pentobarbital). Because the animal will not be recessitated after
- the procedure large quantities of the anesthetic can be used.
-
- Once the animal is clearly "under" the chest cavity is opened to expose
- the heart. Saline solution will be introduced through the atria of the
- heart in order to displace the blood. Thus it is beneficial if the heart
- is still beating in order to facilitate exchange of the fluids.
-
- Next formaldehyde (or another embalming fluid) is introduced through the
- heart. Again if the heart is still beating the embalming fluid is more
- efficiently dispersed through the body.
-
- Certain cells of the body function on ion generated
- electrical gradients (i.e. neurons, muscles etc...). When the membrane of
- the cell becomes permeable to ions (depolarizes) the cell fires. Muscle
- contract. Neurons pass action potentials (electrical signals).
-
- Formaldehyde permeablizes the cells. Thus, muscles contract. Jaws
- become "clenched". Legs start "kicking".
- Nerves responsible for encoding pain (nociceptors) fire.
- But the animal is unconscious. Perhaps even more so than a human
- undergoing surgery.
-
- Now, go back and read the quotes from the leaflet. Ask yourself,
- honestly, "Is this leaflet misleading?" and if so "Why does this
- organization need to rely on such tactics, if infact its cause
- is so correct already?"
-
- Think about it.
