The density of fluorescent processes in the pineal gland 2 months after bilateral crushing of the CST
| Density of fluorescent processes | % of respective sham-operated control | |
|---|---|---|
| Sham | 23 ± 3 | 100% |
| CST crush | 7 ± 2 | 30% |
| Sham + α-MNE | 20 ± 3 | 100% |
| CST crush + α-MNE | 15 ± 1 | 75% |
The density of fluorescent processes of sections of pineal glands was analyzed 2 months after bilateral crushing of the CST (CST Crush) or a sham operation (Sham). Two groups of animals were injected with α-methylnorepinephrine (α-MNE) 1 h before removal of their pineal glands (CST Crush + α-MNE; Sham + α-MNE). The density of fluorescent processes (±SEM) is the number of fluorescent processes counted divided by the number of grid points analyzed and multiplied by 100. Each group contains three to four pineal glands.
