- Background: Studies have reported that as many as 60 % of all students learn in a practical manner, rather than theoretically. However, Internet courses, tight budgets and increasing student numbers augments the demand for laboratory experiments carried out off the university premises. Methods: This pilot study was performed to investigate whether laboratory experiments in physiology performed at home are motivating for, stimulates depth understanding and increases student learning. Pharmacy students were recruited to the project from a five-week physiology course, and were given instruc tions on four stay-at-home experiments. These experiments were then discussed at a seminar. In conjunction to this seminar, a simple survey was filled in by the students. Comments: Our results indicated that this method of learning would be appreciated by the students. Stay-at-home laboratory experiments can never take the place of ordinary laboratory experiments, but could be beneficial as a supplement, not the least by introducing an everyday perspective to the students, allowing them to reflect on connections and relations in every day life.

- Overexpression of alpha(2A)-adrenoceptors contributes to type 2 diabetes in GK rats. We aimed to investigate if alpha(2)-adrenoceptor inhibition affected islet blood flow in these rats. Anesthetized GK and Wistar-F rats were given the alpha(2)-adrenoceptor inhibitor yohimbine (2.5 mg/kg BW) intravenously. The GK rats had higher blood glucose and serum insulin concentrations than WF rats. Yohimbine affected neither of these values in WF rats, but decreased blood glucose and increased serum insulin concentrations in GK rats. Total pancreatic and islet blood flows, measured with microspheres, were increased in GK when compared to WF rats. Yohimbine affected none of the blood flow values in WF rats, whereas islet blood flow in GK rats was reduced to values similar to those seen in WF rats. Overexpression of alpha(2)-adrenoceptors may contribute to the increased islet blood flow seen in GK rats, and may be eligible for pharmacologic intervention.
