[Smoking habits of medical students. Smoking habits of Danish medical students and their knowledge about and attitudes to the tobacco problem].

In 1987, 74 Danish first-year and 90 final-year medical students from Aarhus University participated in a global questionnaire investigation concerning the smoking habits of medical students and their attitudes to the tobacco problem. This investigation was initiated by the International Union Against Tuberculosis and Lung Disease. In order to observe particular characteristics or unexpected findings, the Danish percentage replies were calculated and compared with corresponding average figures for the other European medical students and Danish doctors and the normal population.

On making laboratory report work more meaningful through criterion-based evaluation.

The purpose of this work was to encourage students to base their laboratory report work on guidelines reflecting a quality criterion set, previously derived from the functional role of the various sections in scientific papers. The materials were developed by a trial-and-error approach and comprise learning objectives, a parallel structure of manual and reports, general and specific report guidelines and a new common starting experiment. The principal contents are presented, followed by an account of the author's experience with them.

Factors determining residual volume in normal and asthmatic subjects.

We have studied the mechanisms determining the residual volume (RV), by inducing temporary changes in RV through respiratory manoeuvres and bronchodilation. Four asthmatic and 5 normal subjects inhaled placebo, salbutamol, and ipratropium bromide, and performed maximum expiratory manoeuvres after partial and maximal inspiration. RV and static lung pressure-volume measurements were made in each experiment.
