It stated in your kind honor that, currently, I'm working on anti-inflammatory and analgesic effect of naturally occuring compound in vitro
and in vivo models using macrophages and randall selitto apparatus for analgesic activity.
I watched your video article in Journal of visualized experiments "The Spared Nerve Injury (SNI) Model of Induced
Mechanical Allodynia in Mice"
It is really very nice and impressive animal model for anti-nociceptive effect.
I'm very interested to follow your animal model for evaluation of anti-nociceptive effect of single component isolated
from natural products.
I have some question about this article, would you mind to answer me?
1. What if I use drug to evaluate the analgesic or anti-hyperalgesic effect,so what rout of administration will you
suggest (i.p, s.c or orally?
2. What if I use randall selitto apparatus to measure the withdraw effect?
3. Why you used the ointment in the eye?
Your answers will be highly appreciated.
I'll be very thankful to you.

Dear Salman
I'm happy to hear that you could benefit from your JoVE protocol!
Regarding your questions:
1) I believe this would depend solely on the drug used .. whether this needs to be administered orally or i.p depends on the specific properties of the drug. But in general, injection is preferable as this allows accurate dosage and consistent delivery.
2) We haven't used the randall selitto apparatus on the SNI model so I don't know if this works well. In the SNI model we ligate the main branches of the sciatic nerve and leave the sural nerve intact, this only the lateral part of the paw displays hypersensitivity whereas the rest of the paw is numb. Von frey filaments allow us to test only the hypersensitive area .. I'm not sure if this also is true with the paw pressure test?
3) We use eye ointment during surgery to prevent that the eye dry out during the procedure. The blink reflex is impaired during anesthesia thus we need to protect the eye (especially during longer procedures).
