We investigated the effects of intense magnetic fields on the blood platelet aggregation process with and without static magnetic fields of up to 14 T. A rabbit plasma and collagen mixture was used as the model system for a wounded blood vessel. Platelet aggregation was activated by the stimulation of acid soluble collagen. The platelet aggregates in strong magnetic fields were larger than the aggregates in an ambient field. An optical transmission of blood plasma during platelet aggregation also indicated that strong magnetic fields enhanced blood platelet aggregation in plasma.

derived diazoniumsalts are unstable compounds at neutral pH unless they are able to be deprotonated to the corresponding diazo form. As such, the 2-diazoimidazole-4(5)-acetic acid (3b) is stable in neutral medium and recognizes the GABA receptor (IC50 = 70 microM). The homocyclic aromatic diazoniumsalts showed sufficient stability to be tested in binding experiments. The diazoniumsalts derived from

Die Säurenatur des Diazoniumions wird diskutiert. Am Beispiel von p-Chlorphenyldiazoniumion und m-Sulfophenyldiazoniumion lässt sich zeigen, dass das Diazoniumion sich wie eine zweibasische Säure verhält, deren erste Dissoziationskonstante sehr viel kleiner ist als die zweite.
