Zusammenfassung Vergleich von Glykogenfraktionen aus Ventrikeln männlicher Albinoratten, die 24 h gefüttert wurden, mit Nichgefütterten. Letztere verbrauchten meistens TCA (ungebundenes Glykogen) nach Bewegung, während gefütterte Ratten sowohl Rest-Glykogen (gebundenes) wie auch TCA Glykogen verbrauchten. Die Glykogenabnahme war im linken Ventrikel nach Bewegung grösser als im rechten.

本文调查了上海市百岁老人的性别、职业和谱系,并绘制了57个完整的寿命谱系图,其中男性10名(占总数的17.5%),女性47名(占82.5%).男性中脑力劳动者4名(占男性总数的40%),体力劳动者6名(占60%);女性中脑力劳动者1人(占女性总数的2.1%),体力劳动者3人(占6.4%),操持家务者43人(占91.5%).有长寿家族史者40人(占寿命家族史清楚者的70.2%),无长寿家族史者17人(占29.8%).百岁老人配偶寿长≥70岁者,其已故子女的平均寿命高于配偶<70岁的.作者认为长寿是遗传的,并着重从遗传和环境两方面分析了女寿星数明显多于男寿星数的原因. 相似文献

Cytoimmunotherapy for persistent virus infection reveals a unique clearance pattern from the central nervous system 总被引:36,自引:0,他引:36
The mechanism(s) by which infectious or malignant material is cleared by the host has long been an area of intensive study. We have used the murine model of infection with lymphocytic choriomeningitis virus (LCMV) to look at immune clearance during persistent infection. LCMV was selected because the mouse is its natural host, it easily induces acute or persistent infection in vivo, and the mechanism by which it is cleared in vivo during acute infection is now well understood. Clearance, although associated with several antiviral immune effector mechanisms, is primarily dependent on the activity of virus-specific cytotoxic T lymphocytes (CTL) restricted by H-2 molecules of the mouse major histocompatibility complex (MHC). If these cells fail to generate or are depleted, progression from acute to persistent infection occurs. Here, using molecular probes, we show that viral nucleic acid sequences, viral proteins and infectious materials can be efficiently and effectively cleared by adoptive transfer of antiviral H-2-restricted lymphocytes bearing the Lyt 2+ phenotype. Viral materials are cleared from a wide variety of tissues and organs where they normally lodge during persistent infection. Unexpectedly, the mode by which viral materials are removed from the central nervous system (CNS) differed markedly from the mechanism of clearance occurring at other sites. These observations indicate the possible use of adoptive lymphocyte therapy for treatment of persistent infections and suggest that immune clearance of products from the CNS probably occurs by a process distinct from those in other organs. 相似文献

Neoplasms are thought to progress to cancer through genetic instability generating cellular diversity and clonal expansions driven by selection for mutations in cancer genes. Despite advances in the study of molecular biology of cancer genes, relatively little is known about evolutionary mechanisms that drive neoplastic progression. It is unknown, for example, which may be more predictive of future progression of a neoplasm: genetic homogenization of the neoplasm, possibly caused by a clonal expansion, or the accumulation of clonal diversity. Here, in a prospective study, we show that clonal diversity measures adapted from ecology and evolution can predict progression to adenocarcinoma in the premalignant condition known as Barrett's esophagus, even when controlling for established genetic risk factors, including lesions in TP53 (p53; ref. 6) and ploidy abnormalities. Progression to cancer through accumulation of clonal diversity, on which natural selection acts, may be a fundamental principle of neoplasia with important clinical implications. 相似文献
