The effect of two macrolidic antibiotics, josamycin and erythromycin, on the primary immune response in cultures of human peripheral blood mononuclear cells (PBMC), were studied using a soft agar hemolytic plaque assay. Both compounds induced an appreciable reduction in the primary antibody response in total PBMC cultures. The removal of plastic-adherent cells, however, profoundly modified the effect of macrolides on the immune response. Both josamycin and, to a lesser extent, erythromycin enhanced, rather than suppressed, the antibody response. Furthermore, the macrolide-induced immunodepression in cultures of total PBMC was completely reversed by the addition of catalase (8000 U/ml). Taken together, these findings suggest that the macrolide-induced depression of the antibody response depends upon the presence of adherent monocytic cells and is mediated by the production of hydrogen peroxide. 相似文献

Zusammenfassung Es wird die M?glichkeit der experimentellen Erzeugung einer Fibrosklerose der Lunge mit Substanzen studiert, welche ein Minimum
an Sch?dlichkeit mit einer maximalen Anregung der Fibrose vereinigen und gleichzeitig eine Ablagerung von Kalkasalzen innerhalb
und in der Umgebung der Herde bewirken sollten. Damit verfolgten wir den Zweck, in weiterem Ausbau der Ergebnisse früherer
Untersucher ein wirksames Heilmittel gegen die Lungetuberkulose einzuführen. Die verwendete Substanz war Vitamin D2, dessen Calcium fixierende F?higkeit wir ausnützten und Calciumchlorid als Reizmittel zur Anregung der bindegewebigen Proliferation.
Die Resultate haben in sehr erfreulicher Weise unsere theoretischen Voraussetzungen best?tigt. Denn es entstanden ganze Herde
von bindegewebiger Sklerose mit starker Kalkapposition. Es werden zahlreiche und recht interessante histologische Bilder beschrieben,
darunter auch das Auftreten einer epithelialen Hyperplasie. Schlie?lich werden die gegenseitigen urs?chlichen Beziehungen
zwischen bindegewebiger Sklerose und Kalkablagerung in ihrem günstigen Effekt zur Hemmung des Fortschreitens des tuberkul?sen
Prozesses studiert und besprochen.

Purpose
To compare changes in inferior vena cava (IVC) filter positional parameters from insertion to removal and examine how they affect retrievability amongst various filter types.Materials and methods
A total of 447 patients (260 men, 187 women) with a mean age of 55 years (range: 13–91 years) who underwent IVC filter retrieval between 2007–2014 were retrospectively included. Post-insertion and pre-retrieval angiographic studies were assessed for filter tilt, migration, strut wall penetration and retrieval outcomes. ANCOVA and multiple logistic regression models were used to analyze factors affecting retrieval success. Pairwise comparisons between filter types were performed.Results
Of 488 IVC filter retrieval attempts, 94.1% were ultimately successful. The ALN filter had the highest mean absolute value of tilt (5.6 degrees), the Optease filter demonstrated the largest mean migration (?8.0 mm) and the Bard G2 filter showed highest mean penetration (5.2 mm). Dwell time of 0–90 days (OR, 11.1; P = 0.01) or 90–180 days (OR, 2.6; P = 0.02), net tilt of 10–15 degrees (OR 8.9; P = 0.05), caudal migration of ?10 to 0 mm (OR, 3.46; P = 0.03) and penetration less than 3 mm (OR, 2.6; P = 0.01) were positive predictors of successful retrievability. Higher odds of successful retrieval were obtained for the Bard G2X, Bard G2 and Cook Celect when compared to the ALN and Cordis Optease filters.Conclusion
Shorter dwell time, lower mean tilt, caudal migration and less caval wall penetration are positive predictors of successful IVC filter retrieval. 相似文献106.

Cleft hand is an uncommon congenital malformation, which is defined as a deficiency of the central part of the hand. It results from the absence or alteration of development of the central rays. Although the function of the hand is often excellent, the cosmetic appearance drives parents to seek consultation. The goal of this article is to define the different factors that dictate the classification of this anomaly and to facilitate choosing among many surgical procedures. Treatment improves aesthetic aspect of the hand and maintains excellent function. A retrospective review of 33 operated cases is presented. 相似文献

Stem cell populations have been shown to be extremely versatile: they can generate differentiated cells specific to the tissue in which they reside and descendents that are of different germ layer origin. This raises the possibility of obtaining neuronal cells from new biological source of the same adult human subjects. In this study, we found that epidermal growth factor (EGF) and basic fibroblast growth factor (bFGF) cooperated to induce the proliferation, self-renewal, and expansion of neural stem cell-like population isolated from several newborn and adult mouse tissues: muscle and hematopoietic tissues. This population, in both primary culture and secondary expanded clones, formed spheres of undifferentiated cells that were induced to differentiate into neurons, astrocytes, and oligodendrocytes. Brain engraftment of the somatic-derived neural stem cells generated neuronal phenotypes, demonstrating the great plasticity of these cells with potential clinical application. 相似文献
