Zusammenfassung Die Aktivität der alkalischen Ribonuklease in Peritonealzellen bei Mäusen ist 21-bzw. 7mal stärker als die Aktivität in Thymus- und Lymphknotenzellen. Die meisten ribonukleasereichen Peritonealzellen haften nicht an plastischen Oberflächen. Die Ribonuklease-Aktivität von nichtadhärenten Zellen wird erhöht, wenn Mäuse mit Cortison behandelt werden, und diese Wirkung ist besonders auffallend im Gesamtbestand der peritonealen Zellen. 相似文献

A method was developed which allowed for the isolation of lymphocytes (95% of leukocytes in the final suspensions) from small volumes of peripheral mouse blood (38% recovery). The method proved of value for studies of murine lymphocytes which required biochemical analysis of samples from individual animals on a serial basis. 相似文献

Summary 5 HT content of heart, brain, kidneys and liver in rats increases significantly after repeated exposure to electric shock followed by a trend of normalisation. These changes appear to be organ specific. 相似文献

PHA-activated lymphocytes release colony-stimulating activity (CSA) for macrophage-granulocyte precursor cells (colony forming units, CFUc) in the culture medium. Somatostatin, known to interfer with ribosomal protein synthesis, was demonstrated to reduce the release of CSA from PHA-treated mouse spleen lymphocytes. 相似文献

Different radiolabelled N-acyl-derivatives of D-glucosamine were synthesized using D-glucosamine and the respective carbonic acid anhydride. Metabolism of these sugar analogues could be shown in vitro as well as in vivo. After the intraperitoneal administration of these radiolabelled N-acyl-D-glucosamines to mice, their rate of incorporation into glycoproteins of different organs was found to increase markedly with the length of the N-acyl side chain. Highest incorporation was measured in the whole intestine using N-pentanoyl-D-glucosamine as label. 相似文献

Zusammenfassung Die Heterogeneität der alkalischen Phosphatase in der Rattenleber wird beschrieben. Anodische und kathodische Isoenzyme unterscheiden sich unter anderem durch ihre Reaktion auf die Neuraminidase Behandlung.

Summary Mice treated for 4 days with tolbutamide displayed decreased serum glucose values with a concomitant decrease of their islet insulin content. Mouse islets cultured for 1 week at a low (3 mM) or a high (28 mM) glucose concentration contained less insulin than non-cultured islets and islets cultured at a medium (11 mM) glucose concentration. All groups of cultured islets contained more glucagon than non-cultured islets. The somatostatin content of high- and medium-glucose cultured islets was higher than that of freshly isolated islets.The skilled technical assistance of Astrid Nordin, Ewa Forsbeck and Eva Törnelius is gratefully acknowledged. Financial support was received from the Swedish Medical Research Council (12X-109; 12X-2297), the Nordic Insulin Fund and the Swedish Diabetes Association. 相似文献

Summary An assay system is described that allows the presence of inflammatory factors in supernatants from stimulated tuberculin-sensitive human peripheral blood lymphocytes to be demonstrated, by the induction of an inflammatory exudate in the peritoneal cavity of normal C57 BL mice. 相似文献

Summary The numbers of sister chromatid exchanges in lymphocytes grown in varying concentrations of serum from different sources indicated that some sera contain a factor, probably introduced as a contaminant, which induces SCEs. Sera from 6 animals showed no evidence of a difference in baseline SCE levels due to the donor of the serum.Research sponsored by U.S. Department of Energy contract number DE-ACO5-760R00242 with The University of Tennessee. 相似文献
