I wasn't going to reply to this until I saw Larry's bit about rabbit heart
punctures. I can remember (I graduated in 73) doing a heart puncture on my
rabbit and killed the poor thing. When we cut open the chest it looked like
I used the needle to shred his heart. The only way to get enough blood for
our serology experiment was to siphon the chest cavity. My partner's blood
drawing was much better. Since my rabbit was our negative control I asked
the prof permission to clean it and take it home for dinner. He agreed -
actually he gave me the idea since he used to do it all the time until his
wife got sick from Staph toxins.
Our demonstration of anaphylaxis used a guinea pig and a massive injection
of histamine. We noticed all the symptoms as the poor thing died. We also
did a demonstration of gas gangrene by injecting the peritoneum of a
rabbit.with a little horse manure and then isolating the Clostridium
perfringens from the gut.
Parasitology was even more graphic. Every week we had a live animal to
dissect and collect the parasites.
