Affective modulation of the startle reflex in schizophrenic patients.

Startle-elicited blinks were measured during the presentation of affective slides in order to investigate emotional responsiveness in 24 male healthy subjects and 34 male schizophrenic patients. Although the two groups did not differ with regard to their subjective and autonomic responses to the slide stimuli, there was a significant difference between the groups in their responses to the startle probes. Patients rated low in affective expression showed a linear response pattern comparable to that of normal controls with largest amplitudes during unpleasant slides and smallest during pleasant slides.

Slow cortical potentials (SCPS) in schizophrenic patients during performance of the Wisconsin card-sorting test (WCST).

Fifteen schizophrenic patients (diagnosed according to DSM-III-R) and 15 age- and education-matched controls were tested on a computerized version of the Wisconsin card-sorting test (WCST). Slow Cortical Potentials (SCPs) were recorded throughout the performance from frontal, central and parietal electrode sites. As expected, the patients were impaired on the WCST, achieving fewer categories overall and incurring significantly more "unique" errors, although they were not significantly more perseverative than the controls.

[Bowel cleansing prior to colonoscopy. A prospective, randomized, blind comparative study].

A randomized, prospective, single blind study was performed in 90 hospital inpatients to compare the effect of three different bowel preparatory regimens prior to total colonoscopy. The extend of bowel cleansing, acceptance by the patients, side effects as well as body weight, blood pressure, pulse rate and various laboratory parameters served as major assessment criteria. Peroral colonic lavage was superior to a senna preparation and a combined laxative agent with regard to the extend of bowel cleansing (p less than 0.

Prajmaliumbitartrate-associated liver damage. Report on seven further cases with follow-up for two to five years.

Seven further cases with n-propyl-ajmaliumbitartrate (NPAB)-associated liver damage observed between 1976 and 1980 in two collaborating institutions are reported. The cause/effect relationship could be classified as probable in three cases and as potential in the remaining four patients. No drug rechallenge was carried out.
