16. Responses to reduced industrial metal emissions : An ecotoxicological study on Pied Flycatcher (Ficedula hypoleuca, Aves)
Sammanfattning : Metals have been used by humans for thousands of years, and this has resulted in increased concentrations in the biosphere. The environment around point-sources, such as mines and smelters, are of particular concern, as metals may accumulate to high concentrations, and potentially reach levels toxic to the local flora and fauna.

17. Tryptophan-related Neurotransmission in the Brain: Disturbances Associated with Experimental Hepatic Encephalopathy
Sammanfattning : In the present study, L-tryptophan (TRP)-related disturbances in the brain in experimental hepatic encephalopathy (HE) were investigated. The endogenous NMDA-receptor agonist and L-TRP metabolite quinolinic acid (QUIN) has been suggested to be involved in the pathogenesis of HE. LÄS MER
18. Evolving the Methodology for Detection of Primary DNA Damage : Development, adaptation and assessment of the single cell gel electrophoresis (comet) assay
Sammanfattning : Deoxyribonucleic acid (DNA) is one of the most important molecules in nature. It is the fundamental carrier of evolutionary information and constitutes the genetic blueprint of all living organisms. Being the sole source of information, it is vital for the cell to transmit the correct genetic information from generation to generation. LÄS MER
19. Pharmacokinetic and pharmacodynamic analysis of antidiuretic peptides
Sammanfattning : The clinical pharmacology of desmopressin and a new vasopressin analogue (F992) was investigated in healthy human subjects. The common procedure of overhydration of healthy volunteers when studying the antidiuretic effect of a drug, may affect the pharmacokinetics, in particular the volumes of distribution. LÄS MER
20. Effect of Cholecystokinin-B/Gastrin Receptor Antagonists on Rat Stomach ECL Cells
Sammanfattning : The histamine- and pancreastatin- containing ECL cells in the acid-producing mucosa of the rat stomach operate under the control of circulating gastrin. The present work examines how cholecystokinin (CCK)-B/gastrin receptors regulate the activity of the ECL cells. LÄS MER
