超氧物歧化酶对糖尿病模型大鼠血液和晶状体中自由基及其清除剂的影响

本工作发现糖尿病大鼠晶状体和血液中的ＬＰＯ、ＭＤＡ水平高于正常大鼠，而Ｔ－ＳＯＤ、Ｃｕ·Ｚｎ－ＳＯＤ水平降低（Ｐ＜Ｏ．０１）．观察用不同剂量ＳＯＤ及不同时间的治疗方案，结果大剂量比小剂量，长时间比短时间更能改善自由基和清除剂的状况，提示糖尿病患者晶状体中自由基代谢异常，这可能和糖尿病性白内障有关；表明ＳＯＤ可能是防治糖尿病性白内障的良药．     

Erosion and Sediment Production in Small Watershed in Purple Hilly Areas and Prevention Techniques

Purple Soil distributes extensively and mainly in China. Because of abundant easily weatherable parent rocks/materials and unstable soil structure, and also influenced by parent materials, usage systems, and slope gradients, erosion and sediment production of purple soils are very severe with main fashions of water erosion and gravitational erosion. Basing on observed data in small watersheds, rainfall erosivity,vegetation coverage, previous soil water content, flow and relating factors such as climate, topograph of small watershed,land usage, and soil kinds are all the influence factors of erosion and erodibility of purple soil as well as sediment production and transport in small watershed of purple hilly areas.The effective technological countermeasures of ecosystem restoration, agricultural tillage for water conservation and erosion prevention, agriculture project, and soil changing for fertility and anti-erosion were provided.     

政治学视野中的依法治国与权力制约

近年来“依法治国”的口号响遍神州大地，这在某种程度上反映出中国对法治的重视和需求。然而，口号并不等于实际，法治口号与法治实践之间尚存较大差距，尽管法治口号震天响．公共权力腐败问题仍十分严重，如何防止滥用公共权力和遏制权力腐败，成为当代民主与法治的重大课题，因此要着重从权力制约的价值基础，权力制约在依法治国中的意义及完善我国法治的权力制约机制三方面进行探讨。

Studies on the Dd antigen-antibody system. I. The nature of antigen Dd and its antibodies

Summary The nature of antigen Dd, an antigen present in the extracts of human dandruff which precipitates human sera selectively, and antibodies reacting with it are reported.This work was supported through U.G.C. Grant No. F.23-230/75/SR II. H.K. participated in this study, first as J.R.F. of U.G.C. and then as S.R.F. of I.C.M.R. We are grateful to Dr Baruch S. Blumberg for his invaluable suggestions and to Professor H. Walter for the gift of IgG, IgM and IgA immune sera.     

Energetic landscape of alpha-lytic protease optimizes longevity through kinetic stability.

During the evolution of proteins the pressure to optimize biological activity is moderated by a need for efficient folding. For most proteins, this is accomplished through spontaneous folding to a thermodynamically stable and active native state. However, in the extracellular bacterial alpha-lytic protease (alphaLP) these two processes have become decoupled. The native state of alphaLP is thermodynamically unstable, and when denatured, requires millennia (t1/2 approximately 1,800 years) to refold. Folding is made possible by an attached folding catalyst, the pro-region, which is degraded on completion of folding, leaving alphaLP trapped in its native state by a large kinetic unfolding barrier (t1/2 approximately 1.2 years). alphaLP faces two very different folding landscapes: one in the presence of the pro-region controlling folding, and one in its absence restricting unfolding. Here we demonstrate that this separation of folding and unfolding pathways has removed constraints placed on the folding of thermodynamically stable proteins, and allowed the evolution of a native state having markedly reduced dynamic fluctuations. This, in turn, has led to a significant extension of the functional lifetime of alphaLP by the optimal suppression of proteolytic sensitivity.
