Zusammenfassung Menschliche Blutplättchen in Zitratplasma wurden mit Serotonin-14C inkubiert und danach mit ADP zur Aggregation gebracht. Die spezifische Aktivität des freigesetzten Serotonins war gleich der des in den Plättchen verbliebenen Serotonins.

In a first experiment, cells were cultured in media supplemented by nickel sulphate, irradiated in same media and cultured in same media after irradiation. In a second experiment, cells were cultured during 18 hrs. in media supplemented by nickel sulphate, and then cells were washed and cultured in normal media where they were irradiated. The nickel sulphate toxicity appears as a creasing function of the nickel sulphate concentration and the nickel sulphate action endurance. The nickel sulphate toxic effect is amplified by X-Rays. This amplification is a time function that depends on the X-Ray dose, nickel sulphate concentration and period of time from the outset of culture to the irradiation. The nickel sulphate toxic effect appears faster when nickel works after X-Rays. 相似文献

Glycosaminoglycans isolated from culture medium conditioned by human endothelial cells showed heparin-like anti-thrombin III cofactor activity measured by Xa inhibition. Their activity was relatively weak, 0.1% of the potency of heparin, but was approximately 5-fold more potent than that of glycosaminoglycans derived from vascular smooth muscle cells. 相似文献

Summary The growth characteristics of human leukemic cell lines in serum supplemented medium and in serum free medium with and without the addition of insulin were investigated. No relation was found between the insulin binding capacity of the cells and their hormone-dependence for growth.This work has been supported by grant CT82.00191.04 of CNR Rome and by Regione Piemonte. 相似文献

Summary Cell-free supernatants were harvested from cultures of human skin fibroblasts, were applied on to DEAE-cellulose columns, and the first fraction eluted with phosphate-buffered saline contained the growth-stimulating agent. The eluted fraction was then passed through a series of amicon membranes. After passing through PM-10, the filtrate stimulated growth of bovine vascular endothelial, canine myocardial, and human mammary carcinoma cells. 相似文献

Zusammenfassung CBA Mäuse zeigen nach der Infektion mit dem Rauscher Virus einen starken Anstieg hömopoetischer Stammzellen («colony-forming units») im peripheren Blut. Nach 21 Tagen wird im Zustand der peripheren Erythroblastose eine 50-fache Zunahme gefunden.

Zusammenfassung Der in Form eines hochmolekularen Komplexes von den Plättchen freigesetzte, heparinneutralisierende Faktor (PF 4) konnte reversibel in ein Träger-Material und ein aktives Protein (Molekulargewicht ca. 30000) aufgespalten werden.

Summary Plasminogen activator produced in organ culture of human kidney, i.e. in the histotypical arrangement of the tissue, was partially purified by affinity chromatography on para-aminobenzamidine coupled to Sepharose by a 6-carbon spacer, followed by gel chromatography on Sephadex G-100. The molecular weight of 2 active peaks were 27,000 and 52,000 daltons respectively. It was inhibited by DFP and by IgG antiurokinase.This study was supported by grant from the Swedish Medical Research Council (B77-17X-04523-03B). 相似文献

Zusammenfassung Eine verbesserte Technik zur Gewinnung der ersten Einzelschichtbildungen von Froschnierenzellen wurde entwickelt. Die Zellen werden in neuem auflösendem Nährboden isoliert und wachsen auf modifiziertem Eagle-Nährboden mit 13% Kalbsserum. Nach 10 Tagen zeigt sich stark aktives mitotisches Zellwachstum in der Kultur. 相似文献
