Effects of pregnancy on the mean optical density per area unit (OD) and integrated optical density (IOD = OD × cytoplasmic area) of TrkA and p75 in Fluorogold-positive uterine-projecting sympathetic neurons of the rat thoraco-lumbar sympathetic chain
| Receptor | Stage | n | OD – Median | IQR | IOD Median | IQR |
|---|---|---|---|---|---|---|
| TrkA | Control 16W – DO | 104 | 149 | 144–163 | 48049 | 49009–59031 |
| Pregnant | 71 | 187a | 164–189 | 51418 | 46022–58878 | |
| p75 | Control 16W – DO | 74 | 102 | 105–127 | 35697 | 36113–47503 |
| Pregnant | 60 | 79b | 78–98 | 25122c | 26182–38798 |
Results are expressed as median (interquartile ranges, IQR). Data pairs were compared by the Mann–Whitney non-parametric test. n = number of neurons.
a
Significant difference in TrkA OD (P < 0.005) against the adult control in dioestrus (DO).
b
Significant difference in p75 OD (P < 0.001) against the adult control in dioestrus (DO).
c
Significant difference in p75 IOD (P < 0.01) against the adult control in dioestrus (DO).
