Intrathecal implants of bovine chromaffin cells alleviate mechanical allodynia in a rat model of neuropathic pain

Patrick Aebischer

Intrathecal implants of adrenal chromaffin cells are known to release analgesic substances such as catecholamines and opioid peptides. In the present study, bovine chromaffin cells were encapsulated in a permselective polymer membrane which protects the ce ...

Effects of the kappa opioid receptor antagonist MR-2266-BS on the acquisition of ethanol preference

Maria del Carmen Sandi Perez

Using a paradigm by which rats forced to drink a weak ethanol solution (2.5% w/v) (conditioning session) develop ethanol preference in consecutive retention testing days, the effects of the administration of the kappa opioid antagonist MR-2266-BS, prior to ...

Involvement of kappa type opioids on ethanol drinking

Maria del Carmen Sandi Perez

The effects of the administration of the kappa agonist dynorphin1-17 and/or the kappa antagonist MR-2266-BS on ethanol preference was investigated using a paradigm by which rats develop alcohol preference. Administration of dynorphin shortly before or afte ...
