    A syndrome of multiple gastrointestinal atresias with intraluminal calcification (1979)
    Springer
    Pediatric radiology 8 (1979), S. 227-231

    Notes: Abstract An infant with multiple gastrointestinal atresias from the stomach to the rectum is reported and the literature concerning this syndrome is reviewed. The syndrome has been reported, to date, exclusively in infants born to families with a French-Canadian background. The radiological hallmark of this syndrome is extensive calcification of intraluminal content between the areas of atresia which appears as rounded or oval homogeneous radiopacities on abdominal radiographs. Inheritance is thought to be autosomal recessive and the etiology is uncertain. All previously reported cases have died. The significance of biliary gas, seen in postoperative films, is discussed.

    DDC-Induced amnesia and norepinephrine: A correlated behavioral-biochemical analysis (1979)
    Springer

    Notes: Abstract Diethyldithiocarbamic acid (DDC), a dopamine-B-hydroxylase inhibitor, when injected into rats 30 min to 6 h before training of a passive avoidance task, impaired formation of long-term memory as indicated by performance on a retention test 24 h later. Performance of the task was at its minimum when injection occurred 2 to 4 h prior to training; recovery was evident in animals trained 5 or 6 h after drug treatment. Catecholamine assay of brains of temporally yoked animals showed that norepinephrine depletion followed a time course paralleling that of the amnesia. These findings support the hypothesis that the degree of memory storage, as reflected in performance following training in a passive avoidance task, can be directly correlated with the level of norepinephrine existing at the time of training.

    Interaction between discrimination of drug states and external stimuli (1979)
    Springer
    Psychopharmacology 61 (1979), S. 105-106 
    Details
    ISSN: 1432-2072
    Keywords: Ethanol ; External stimuli ; Drug-induced stimulus control ; Discrimination
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract Rats learned a two-choice operant response by discriminating differences between external stimuli, internal (drug-produced) stimuli, or a combination of these two types of stimuli. Separate groups of rats were used for each stimulus condition. A tactile and visual external cue was superior to the ethanol-saline cue in producing stimulus control, but the group receiving both drug and external stimulus cues performed in a manner very similar to the external cue-only group. The two stimulus sources thus did not “add” to promote more rapid or complete discrimination. After acquisition of discrimination, previously coincident drug and external stimulus states were reversed to determine which stimulus source had more behavioral control. This test for stimulus selectivity indicated that the external stimulus had essentially complete control of response choice.
