1. Reactivity of human omental blood vessels. Effects of 5-hydroxytryptamine, substance P and the intravenous anaesthetic propofol
Sammanfattning : Regulation of blood flow involves several endogenous substances and mechanisms, and exogenous substances may also affect the blood flow. In the present thesis, human omental blood vessels were investigated in vitro concerning (i) characteristics of 5-hydroxytryptamine (5-HT) receptors; (ii) mediators of substance P (SP)-induced relaxation; (iii) direct and indirect (via effects on sympathetic neurotransmission) effects of the intravenous anaesthetic propofol.

2. Gene expression in human adipose tissue. Studies of leptin and genes selected by expression profiling
Sammanfattning : Obesity, and in particular the amount of visceral adipose tissue, is correlated to development of type 2diabetes and cardiovascular disease. The aim of this thesis was to study genes expressed in humanadipose tissue that could be involved in regional adipose tissue homeostasis and/or obesity-associateddisease. LÄS MER
3. Anaesthetics and the blood vessel wall. Actions of propofol and sevoflurane on sympathetic and endothelial control of smooth muscle function
Sammanfattning : The anaesthetics we use today dose-dependently decrease the mean arterial pressure partly due to direct or indirect effects on the blood vessels. In the present thesis human omental arteries and veins and rat femoral arteries were investigated in vitro concerning the effects of the intravenous anaesthetic propofol and the volatile anaesthetic sevoflurane on the function of the perivascular sympathetic nerves and the endothelial cells.

4. Interplay between hormones, nutrients and adipose depots in the regulation of insulin sensitivity : an experimental study in rat and human adipocytes
Sammanfattning : Obesity and specifically central obesity is related to insulin resistance, type 2 diabetes and other components of the so-called metabolic syndrome. The aim of this study was to elucidate the interplay between hormones, nutrients and adipose depots in normal and insulin-resistant fat cell metabolism. LÄS MER
5. A study of potassium channel activation as a pharmacological principle for vasodilation of cerebral blood vessels
Sammanfattning : Increasing [K+]o is intimately coupled to progressive ischemia and reduced CBF. In isolated cerebral and mesenteric arteries, it was found that significant differences in the vascular responses to [K+]o exist. Among the species studied, human cerebral arteries were the most sensitive artery to increasing [K+]o. LÄS MER
