    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.
