We conducted a paleo-parasitological study on soil samples from the ancient moat ruins of Weolseong palace, of the Silla Dynasty (BC 57–AD 935) of Korea. Based on the cultural remains found in the mud-soil layer, the layer was precipitated onto the floor of a moat between the 5th and 8th centuries AD. We found Trichuris trichiura eggs only in that mud-soil layer, whereas no parasite eggs were identified in the other archaeological strata of the ruins. As T. trichiura eggs are shed only in human feces, we speculated that palace toilet contents were continually drained into the moat; therefore, at a certain point in time after construction, the moat finally became a ditch around the palace. Structures in the stone embankments of the moat, possibly designed to make the water flow continuously in one direction, might reflect the Silla people's efforts to alleviate the ever-increasing problems inherent in a moat. 相似文献

自1799年《反结社法》颁布至《1974年工会和劳资关系法》出台的近两百年间,英国工会的法律地位经历了从非法状态到被有限承认再到享有法定特权的漫长历程,伴随着工会地位的这种转换,英国政府的劳资政策也相应发生了从立法打压到建立仲裁调解制度再到确立集体谈判制度的历史嬗变。 相似文献

Despite high prevalence of Trichuris trichiura infection, PCR-based analysis on T. trichiura from archaeological samples has not been established so far. In the present study, we sought to perform PCR-based amplification of T. trichiura aDNA using the sediments from medieval tomb of Korea. The presence of Trichuris eggs were first detected by microscopic observation; then confirmed by PCR-based aDNA analysis. Obtained sequence showed 100% homology to that of the small subunit ribosomal RNA (SSUrRNA) gene of T. trichiura but distinct from that of other Trichuris species. PCR-based aDNA analysis in this study can serve as effective method to confirm the presence of T. trichiura eggs in the soils or coprolites collected from archaeological sites. 相似文献

本文通过西汉王朝的辖区设治与军事戍防的探述,揭示该王朝经邦治国的若干层面及其利弊得失。文中探述表明,西汉更秦而立,开创了早期我国统一多民族国家形成和发展的非凡业绩,作为经邦治国的重要领域,其辖区设治与军事戍防的建树和成功的一面,直接促进了国内经济、文化和科学技术等方面的繁荣发展,在我国统一多民族国家前进的历史上,留下了光辉的一页。同时也应该看到,西汉王朝弊政的产生和积累,最后加速其灭亡的教训也是深刻的,值得加以总结、吸取。 相似文献
