Summary Cortisol induces a migration of eosinophil leukocytes from the blood to several lymphoid organs, such as the spleen, lymph nodes and thymus, but not to other tissues. This migration explains the cortisol-induced blood eosinopenia, which is much more pronounced in intact than in splenectomized animals.Acknowledgments.

The effect of prolonged food deprivation on the triglyceride level in different types of skeletal muscle was studied in the rat. It has been found that fasting gradually reduces the triglyceride content in each muscle type. It is concluded that i.m. triglycerides play an important role as energy fuel during fasting. 相似文献

An enhancement effect of mouse erythrocyte rosette forming (MERF) cells on the production of migration inhibitory factor, chemotactic factor for neutrophils and skin reactive factor in T-lymphocyte cultures stimulated with the purified protein derivative of tuberculin was observed. We consider it likely that the MERF cells, possessing the appropriate cell surface constituents to construct an immunogenic moiety, present antigen on their surfaces to elicit lymphokine production. 相似文献

Zusammenfassung Mutter-Sohn-Kreuzung bei der südamerikanischen HummelBombus atratus Franklin ergab diploide Männchen mit normalen Arbeiterinnen im Verhältnis von 3 zu 1. Tur Interpretation des genetischen Mechanismus wurden 2 geschlechtsgebundene Loci angenommen, als bisher angenommen wurde, was für einen älteren Mechanismus bei Apiden spricht.

Polycationic modified derivatives of polyglutamic acid are at least as good enhancers of poly I:C induced viral resistance in various cell cultures as are DEAE-dextran or poly-L-lysine. 相似文献

Résumé L'absence d'un Tm lors de perfusion en quantité croissante de bilirubine non conjuguée chez le rat Gunn, ainsi que la diminution de la concentration biliaire de la bilirubine totale lors d'infusion simultanée de bilirubine non conjuguée et de Novobiocine, suggèrent la possibilité d'un transfert passif de la bilirubine non conjuguée du sang dans la bile, à travers la cellule hépatique. 相似文献

Summary Chemotactic responsiveness and random movement of cord-blood granulocytes were studied with a modified Boyden's method. Cord-blood granulocytes were less active chemotactically than granulocytes from healthy children and adults, whereas the random filter movement of the cells from all three sources was about the same. In cord sera, concentrations of cell directed chemotaxis inhibitors were equal to those in sera from other age groups. Compared with the situation in healthy children and adults, the generation of chemotactic factors in cord-blood sera was impaired. This impairment was not related to an increased activity of chemotactic factor inactivators. Measurement of the cyclic nucleotide levels in granulocytes from cord-blood and from children belonging to various age groups revealed that the cord granulocytes have significantly lower concentrations of cAMP and cGMP, which could have been responsible for the decreased chemotactic responsiveness. 相似文献

Summary Depressor responses evoked by single volleys in the aortic nerve are more facilitated by conditioning volleys exciting C fibers in the same aortic nerve than in the contralateral one. Conditioning volleys in A fibers do not facilitate the testing depressor responses. 相似文献
