Studies from our laboratory have previously shown that two opioid agonists (morphine and [D-Met2,Pro5]enkephalinamide) aggravate, whereas naloxone inhibits cold-restraint stress-induced ulceration in rats. In the present study the effects of these substances were examined using the Shay-model. Contrary to expectations, both naloxone and the opioid agonists(More)
The aim of the present investigation was to examine which areas of the brain might mediate the anti-apomorphine action of some opioids, which were found previously to be active upon subcutaneous application. As the first step, the substances were injected intracerebroventricularly or into the nucleus accumbens, a mesolimbic region which is rich in dopamine,(More)
Fifteen patients with refractory B-cell lymphoma were treated in a Phase I dose escalation clinical trial with a highly potent immunotoxin consisting of the Fab' fragment of a monoclonal anti-CD22 antibody (RFB4) coupled to chemically deglycosylated ricin A chain. All patients had low, intermediate, or high grade non-Hodgkin's lymphoma. The immunotoxin was(More)
The effects of D-Met2, Pro5-enkephalinamide (EA) on pain tolerance and some cognitive functions have been examined in healthy male volunteers. Dihydrocodeine (DC) was used as reference substance. Applying the submaximum effort tourniquet technique EA (10 mg SC) was found to elevate the pain threshold similarly to DC (20 mg SC). Neither DC nor EA impaired(More)
