ABSTRACT
OBJECTIVE: It was hypothesized that binge eating (bulimia nervosa [BN]) may be caused by the anticipatory and immediate anxiety associated with certain types of food. Consequently, an extinction schedule should reduce binge eating. METHODS: Cue exposure was carried out with 6 bulimic women who had responded poorly or not at all to the usual pharmacologic or cognitive-behavioral treatments. RESULTS: Binge eating and vomiting were almost totally suppressed in the 6 patients. Symptom suppression was maintained at two follow-ups, one at 4-20 months and another at 2.5-3 years. DISCUSSION: Cue exposure may be effective with BN that is resistant to conventional treatments. The anxiety associated with food plays an important role in provoking and/or maintaining binge eating. Motivation to change is likely to be an important mediator.

The system formed by 2-mercapto-3-phenylpropanoate (MPP), nickel(II) and hydrogen ions in 30% (v/v) ethanol-water at 25 degrees and I = 100mM (nitrate) has been characterized by means of glass-electrode potentiometry. Protonation constants for 2-mercapto-3-phenylpropanoate and formation constants for the complexes Ni(3)(MPP)(2-)(4) and Ni(MPP)(2-)(2) are reported.
ABSTRACT
The dissociation constants of 3-phenyl- and 3-cyclohexyl-2-mercaptopropenoic acids have been determined spectrophotometrically (I = 0.01M) in aqueous medium, and potentiometrically for both reagents and for 3-phenyl-2-mercaptopropanoic acid in water-ethanol medium. The analytical properties of the three compounds have been studied and also the compositions of some of their insoluble metal chelates.
