Long-lasting effects of escalating doses of d-amphetamine on brain monoamines, amphetamine-induced stereotyped behavior and spontaneous nocturnal locomotion
(Elsevier, 1987-04)
The repeated intermittent administration of relatively low doses of amphetamine (AMPH) produces an enduring hypersensitivity to the motor stimulant effects of AMPH (behavioral sensitization), and this accompanied by enhanced ...
Behavior maintained by intravenous injection of codeine, cocaine, and etorphine in the rhesus macaque and the pigtail macaque
(Springer-Verlag, 1980-10)
Lever-pressing behavior of two species of macaque, the rhesus macaque ( M. mulatta ) and the pigtail macaque ( M. nemestrina ) was maintained by intravenous injection of codeine, etorphine, or cocaine. Monkeys responded ...
Phobic anxiety does not affect plasma levels of thyroid stimulating hormone in man
(Elsevier, 1982)
(1) The effect of anxiety on plasma levels of thyroid stimulating hormone (TSH) is not clear, despite a number of relevant studies. (2) Nine human subjects with severe phobias had blood samples taken for TSH assay every ...
Impact of urban nature: A theoretical analysis
(Elsevier, 1984-10)
The stresses and strains of the urban environment are widely acknowledged. The means for recovery, for recuperation, are perhaps less evident. In particular, the role of environmental configurations in this process is often ...
Similarity of the discriminative stimulus effects of ketamine, cyclazocine, and dextrorphan in the pigeon
(Springer-Verlag, 1981-05)
Separate groups of pigeons were trained to discriminate the IM injection of ketamine, cyclazocine, or dextrorphan from saline. Each of the training drugs and phencyclidine produced dose-related, drug-appropriate responding ...
A tail withdrawal procedure for assessing analgesic activity in rhesus monkeys
(Elsevier, 1986-06)
Rhesus monkeys were restrained in chairs from which their tails hung free so that their tails could be immersed into a thermos of water. Monkeys consistently kept their tails in 38-40[deg]C water for at least 20 sec, but ...
Onchocerca volvulus heat shock protein 70 is a major immunogen in amicrofilaremic individuals from a filariasis-endemic area
(Elsevier, 1989-03-15)
Infestation with organisms causing lymphatic filariasis (i.e. Wuchereria bancrofti and Brugia malayi) results in a variety of clinical presentations. It is possible that some of the variation is due to differences in host ...
Sensitization of rotational behavior produced by a single exposure to cocaine
(Elsevier, 1985-05)
In rats with a unilateral 6-OHDA lesion of the substantia nigra a single exposure to cocaine significantly enhanced the ipsiversive rotational behavior produced by a second injection given one week later. It is concluded ...
Discriminative stimulus effects of etorphine in rhesus monkeys
(Springer-Verlag, 1981-03)
Two rhesus monkeys were trained to discriminate the IM injection of etorphine (0.001 mg/kg) from saline in a task in which 20 consecutive responses on one of two levers resulted in food delivery. In both monkeys, etorphine ...
Differential recognition of two cloned Brugia malayi antigens by antibody class
(Elsevier, 1989-07)
The humoral and cellular immune response to filarial parasites is complex. Numerous studies have shown that antibodies to a large number of protein and non-protein antigens may be produced over the course of infection and ...
