| 1. | Levels of beta-carbolines and hordenine have also been reported.
|
| 2. | More detailed discussions of hordenine pharmacology and toxicology are given below this section.
|
| 3. | Furthermore, hordenine is localized primarily in the roots.
|
| 4. | The potency of tyramine in this receptor preparation was slightly higher than that of hordenine.
|
| 5. | However, the cardiac symptoms of " sudden death " could not be evinced by hordenine.
|
| 6. | The labelled C in the hordenine is thus the C which is ?-to the N.
|
| 7. | The cardiovascular and other effects of hordenine were reviewed in detail by Reitschel, writing in 1937.
|
| 8. | The same dose of hordenine given orally did not produce any of the effects seen after parenteral administration.
|
| 9. | The investigators concluded that hordenine acted as an inhibitor of NE re-uptake in rat vas deferens.
|
| 10. | However, the response to NE of isolated vas deferens taken from rats chronically pre-treated with guanethidine was not affected by hordenine.
