Propionic acid (PPA) is a dietary short chain fatty acid and a metabolic end-product of enteric bacteria. Intracerebroventricular (ICV) injections of PPA can result in brain and behavioral abnormalities in rats similar to those seen in humans suffering from autism. To evaluate cognition and sensorimotor ability in the PPA model, male Long-Evans hooded rats(More)
Rats in a runway avoidance task responded to a test shock probe with a period of immobility lasting from 2 to 6s. The shock avoidance-trained group displayed hippocampal theta during the immobility response. The inescapable shock group, in contrast, displayed large amplitude irregular activity (LIA). Following reversal training to escapable shock, all shock(More)
Abstract The plasma immunoreactive adrenocorticotropin and cortisol responses to oral fenfluramine hydrochloride (1.5mg/kg body wt) or placebo were examined in 11 patients with myotonic dystrophy, 4 controls with facioscapulohumeral dystrophy, a similarly debilitating muscle wasting disease, and 14 normal controls in single-blind studies performed in(More)
Abstract We administered intramuscular arginine vasopressin (AVP) to ten normal controls and eight myotonic dystrophy patients. By measuring plasma AVP levels in five of the myotonics and all the normals, we showed that absorption and distribution of AVP was not delayed or significantly reduced in myotonics. The magnitude of the mean plasma(More)
