1. On the clinical use of digitalis : with reference to its prescription, maintenance therapy, intoxication and the patient's knowledge
Abstract : Digitalis in one of the most frequently prescribed drugs, especially to elderly people. The prescription of cardiac glucosides (1978) was studied by using statistics from Apoteksbolaget (the National Corporation of Swedish Pharmacies). READ MORE

2. The Ecology of Floral Signals in Penstemon digitalis
Abstract : In this thesis, I combined field observations and lab experiments to explore the ecological significance of floral signals in a North American wildflower, Penstemon digitalis. More specifically, to determine the potential mechanisms driving selection on floral scent, I studied how scent mediates interactions with pollinators and antagonists by (1) observing spatiotemporal variation in scent emission (2), floral volatile ability to suppress microbes (3) the honest advertisement of nectar, and (4) if scent could aid pollinator learning by reinforcing visual signals.

3. Studies on Cytotoxic and Neutrophil Challenging Polypeptides and Cardiac Glycosides of Plant Origin
Abstract : This thesis examines the isolation and characterisation (biological and chemical) of polypeptides from plants. A fractionation protocol was developed and applied on 100 plant materials with the aim of isolating highly purified polypeptide fractions from small amounts of plant materials. READ MORE

5. Cytotoxic Compounds of Plant Origin – Biological and Chemical Diversity
Abstract : The development of resistance by tumour cells to chemotherapeutic agents is a major problem in cancer treatments. One way to counter this is to find compounds with cytotoxic mechanisms other than those of drugs in clinical use today. READ MORE
