从尚艳到崇雅——论《御览诗》、《极玄集》在中晚唐诗风衍变历程中的座标意义

《御览诗》和《极玄集》分别编成于宪宗元和后期和文宗开成初年。前者喜尚轻艳,追摹齐梁;后者推崇清雅,回归大历。不同的风格特征、相异的审美追求,清晰地透现出中晚唐之际士人心态的变化及诗风衍变的动态历程,在唐诗发展史上极具座标意义。     

企业合并中商誉的会计处理方法

随着我国经济体制改革的深化，企业间的合并活动日益频繁，但对与企业合并密切相关的商誉问题的处理却不够规范，为此从商誉的含义入手对合并商誉进行了研究，通过对商誉在企业合并后的会计处理方法的探讨，认乌拿兰商誉是由购买价格超过拥有的净资产公允价格的差额确认，确认后的商誉应在规定的年限内用直线法摊销。

Evaluation of the hepatotoxicological effects of a drug in an in vivo/in vitro model

Both in vivo and in vitro models have certain disadvantages for the study of the chronic hepatotoxicity of drugs. The aim of this work was to evaluate a new approach based on an in vivo/in vitro model. After chronic in vivo treatment of rats with Vincamine and Vindeburnol (an eburnamenine derivative which exhibits hepatotoxic properties in man) liver cells were isolated, and functional and metabolic disorders (metabolic utilization of fructose and protein biosynthesis) were studied to determine injury. The results showed no modification of blood parameters, but a direct relationship between the dose of Vindeburnol administered in vivo and the metabolic disorders observed in vitro, evidencing the high sensitivity and reliability of this model.     

Suitability of urethane anesthesia for physiopharmacological investigations in various systems Part 1: General considerations

Summary The suitability of urethane anesthesia for physiopharmacological investigations is reviewed. Total dose administered and route of administration are recognized as factors having a great influence on both resting parameters and biological responses to drugs. A peculiar characteristic of urethane is represented by its ability to induce a surgical plane of anesthesia without affecting neurotransmission in various subcortical areas and the peripheral nervous system. This makes urethane a suitable general anesthetic for studying neural function in both central and peripheral nervous systems and accounts for the preservation of a number of reflex responses in urethane-anesthetized animals.     

The in vivo expression of the globin genes of theβ cistron in γ-,δ-, andδβ-thalassemia heterozygotes

There is considerable evidence suggesting that the switch from to and chain production after birth is due, in part, to silencing of the genes by stage-specific factors which bind to their promoters and to the competition from the adult ( and ) genes for a common enhancer element located in the locus control region. As a consequence one can expect that the increased Hb F production in adults with hereditary persistence of fetal hemoglobin or -thalassemia is directed mainly by -globin genes in cis to the deletion(s) responsible for these conditions. Here we review data on heterozygotes with -, -, or -thalassemia, who also had an^AT mutation, in cis or in trans, which was used as a marker of gene expression. The results show that a deletion affecting adult genes favors the expression of genes in cis, while the deletion of a single gene does not affect the expression of the gene in cis but leads to a faster switch postnatally.
