    Notes: Abstract The responsiveness of the hepatic supernatant NAD+-dependent aldehyde dehydrogenase with a high Km value (high Km-AldDH) to phenobarbital (PB) and 3-methylcholanthrene (3-MC) treatment was studied in male rats of three strains; Wistar, Long-Evans, and Sprague-Dawley. A remarkable strain difference in the response of the enzyme to PB or 3-MC was observed. In rats of the Wistar strain the enzyme activity remained unchanged (“non-responsive”) in all rats after treatment with PB while it increased (“responsive”) 5- to 19-fold in all rats after treatment with 3-MC. The enzyme activity increased 8- to 20-fold and 2- to 8-fold respectively after treatment with PB and 3-MC in all rats of the Long-Evans strain. In rats of the Sprague-Dawley strain the enzyme activity remained unchanged in half of all the rats treated with PB or 3-MC and increased 2- to 7-fold over the basal level in half of the treated rats. The non-responsive rats to PB were all responsive to 3-MC treatment while the responsive rats to PB were responsive in 65% and non-responsive in 35% to 3-MC treatment.

    Esophageal motor abnormalities in scleroderma and related diseases (1966)
    Springer
    Digestive diseases and sciences 11 (1966), S. 522-535

    Notes: Summary Esophageal motor activity was measured by intra-esophageal pressure recordings in 53 patients with scleroderma and 29 patients with other collagen diseases. The purpose of the study was to determine the relationship of motor abnormalities to esophageal symptoms, to compare the abnormalities in scleroderma with those in other collagen diseases, and to try to increase understanding of the responsible mechanism. Methacholine was given to 36 of the 53 patients with scleroderma to confirm that the Mecholyl test is negative in scleroderma and to see whether intraluminal pressure changes accompany the resulting improvement in esophageal emptying. Abnormalities in the intraluminal pressure response of the esophagus to deglutition were seen in 79% of the patients with scleroderma. Of those with an abnormal swallowing pattern, 62% showed diminution or absence of the lower esophageal sphincter pressure zone. Although changes in swallowing pattern did not correlate with esophageal symptoms, absence of lower esophageal sphincter pressure did. The 29 patients with other collagen diseases had similar but less severe abnormalities in the motor response to deglutition. Usually there was better preservation of the lower esophageal sphincter. Neither abnormality correlated with esophageal symptoms in this group. The Mecholyl test was negative in patients with scleroderma. No significant change was found in the pressure studies after methacholine. Of the 66 patients who had both X-ray and manometric studies of the esophagus, intraluminal pressure studies showed aperistalsis in all patients without peristalsis on X-ray studies as well as in 18 patients who appeared to show normal esophageal peristalsis on X-ray studies.

    Behavioral parasitology and perspectives on miracidial host-finding (1979)

    Notes: Summary This paper proposes and outlines a new interdiscipline, ‘behavioral parasitology,’ and presents some interpretations in one of the leading themes of this field, miracidial chemosensitivity to snails. Controversies over miracidial attraction and species-specificity are considered from the standpoints of the distinction between taxis and kinesis, the need for a stimulus gradient, and the possibility of an early phase in a miracidium's behavior adapted for dispersal rather than host-finding. Some of the many possible organic stimulants are discussed with regard to quantitative production by snails, sensory thresholds of the parasites, and possible interaction with inorganic ions. Organic and inorganic stimulants are considered to possibly from qualitative as well as quantitative gradients. A thermodynamic interpretation of miracidial klinokinesis as a function of stimulant concentration suggests the existence of two or more separate types of receptors for the same stimulant, one with a higher affinity for the stimulant and mediating a weaker klinokinesis (possibly a long-range receptor as compared to the other).
