Hypothesis
Does celecoxib improve functional recovery after sciatic nerve crush in rats?
Conclusion
Celecoxib treatment significantly accelerates functional recovery after sciatic nerve crush in rats.
Supporting Evidence
- Rats treated with celecoxib showed significantly better sciatic functional index scores compared to the control group on day 7.
- Motor and walking onset occurred earlier in the celecoxib group compared to the control group.
- All animals had normal SFI values before surgery, indicating no pre-existing impairment.
Takeaway
This study found that giving a medicine called celecoxib to rats with a hurt nerve helped them get better faster.
Methodology
The study involved 15 male Wistar rats divided into three groups: experimental (celecoxib treatment), control (saline), and sham (no crush). Functional recovery was assessed using the sciatic functional index (SFI) over 21 days.
Potential Biases
Potential bias due to the lack of histological or electrophysiological evidence to support the conclusions.
Limitations
The small sample size and large standard deviation limit the statistical power of the findings.
Participant Demographics
15 male Wistar rats, weighing 250–300 g.
