Objective To establish HPLC-UV method for determination of glycyrrhizin acid in compound nasal spray of glycyrrhizin and flower flos magnoliae,the chief active ingredient of formulation,glycyrrhizin acid,and to observethe therapeutic effect of this formulation on guinea pig's hypersensitive rhinitis.Methods A compound nasal spray formulation was prepared using extracts of glycyrrhizin and measured by HPLC-UV method.Mobile phase conˉsisted of methanol,0.2mol/L ammonium acetate and glacial acetic acid(67:33:1,v/v),analytical column was Zorbax ODS C 18 and wavelength250nm.

It all started in the 1920s, when a geologist from the University of Chicago named J Harlan Bretz concluded that the overblown topography in the Scablands was created by a sudden deluge, not the slow uniform processes of erosion and glacial scouring.
这些都开始于二十世纪二十年代,芝加哥大学一位名叫J.HarlanBretz的地质学家得出结论,疤地宏大的地形是由于突发的洪水所致,而不是徐缓而均匀的腐蚀和冰川过程。

We show that over timescales ranging from 500~10000 years, allele frequency data for polymorphic allozymes reveal a consistent loss of genetic diversity along invasion routes, confirming the role of glacial refugia as centres of genetic diversity over these timescales, and that populations in the invaded range are more subdivided genetically than those in the native range of each species.
从500~10 000年的时间尺度上,多态的等位酶位点上等位基因频率的数据表明:1)遗传多样性沿入侵路线呈不断下降的趋势,支持了冰河期避难所作为遗传多样性中心的作用;2)入侵地区的种群与该物种原产地的种群相比,遗传上的分化更为强烈。

Along the low altitudinal plateau edge, haplotypes A, B and C tended to be fixed or nearly fixed in different populations, indicating that the species may have survived the last glacial period in different refugia within this area, and the bottlenecks due to the repeated reduction and expansion of the population size resulted in the reduction of biodiversity.
在低海拔的高原边缘,Hap A、Hap B和Hap C高频率固定在不同的居群中,表明可能存在多个不同的避难所,居群反复缩小和扩张的瓶颈效应造成了遗传多样性的丢失。

Exposure ages of bedrock samples taken from two nunataks in the Grove Mountains, interior East Antarctica, are studied by dating in situ produced cosmogenic 10Be and 26Al. The results indicate that the minimum exposure time of the five samples are all about 2Ma, much older than that of Last Glacial Maximum.
采自东南极内陆格罗夫山地区两个冰原岛峰的五个基岩样品的原地生成宇宙成因核素1 0 Be和2 6Al测试结果表明,这五个样品的最小暴露年龄都在 2Ma左右,远远早于末次冰期极盛期。

The coral is thought to have formed initially on a flat surface: then as the sea-level rose in post-glacial times, thereby submerging the irregular wave-cut platform, the coral growth kept pace with the rising ocean level, so creating the great thickness witnessed today in such places as the Great Barrier Reef off the East coast of Queensland, Australia.
珊瑚被认为最初在平面上形成:然后随著冰河期海平面的上升,淹没了这不规则的波浪冲刷成的平台,珊瑚的生长和海平面的上升同步,因此造成了今天所看到的巨大的珊瑚礁,像澳大利亚昆士兰州东海岸线大堡礁。
