小鼠表皮生长因子对鸡胚角膜上皮组织的增殖效应

鸡胚角膜上皮组织离体培养试验表明，小鼠表皮生长因子对１０日龄鸡胚角膜上皮组织有显著的增殖效应。培养２４ｈ的实验组角膜上皮厚度较正常胚胎角膜上皮厚度增殖９．４３倍，提示鸡胚角膜上皮组织离体培养可作为评价表皮生长因子制剂活性的生物检定法。     

解读短篇小说《献给爱米丽的玫瑰》中的创作特色

威廉·福克纳是美国文学史上久负盛名的小说家之一,他善于运用多种艺术手法表现深刻的社会内涵。其短篇小说名篇《献给爱米丽的玫瑰》通过爱米丽的爱情悲剧揭示了美国南北内战后社会历史的变迁。本文试图从时序颠倒、叙事视角、象征等方面简要分析福克纳在这篇小说中的创作特色,并由此来探讨该小说的深刻内涵及其艺术性。

Occurrence of polyploidy and multinuclearity in the differentiating liver of chick embryo

Summary Increase in nuclear size in liver has been used as an index of polyploidy. It has long been considered that the occurrence of polyploidy and multinuclearity are characteristics of mammalian liver. The present study shows the occurrence of these phenomena in the liver of birds, so these features are not confined to mammals. 3 classes of nuclear size groups have been identified. The simultaneous occurrence of polyploidy and binuclearity indicates some sort of interrelationship between them.     

Teratogenicity screening in standardized chick embryo culture: Effects of dexamethasone and diphenylhydantoin

Summary Teratogenic and toxic effects of DXM and DPH were tested using a standardized chick embryo culture. Survival, growth and malformations were scored with respect to the drug concentrations used. DXM (>10^–8 mol/l) inhibited the differentiation of the extraembryonic blood circulation and induced craniofacial anomalies. DPH (>1.5 10^–5 mol/l) induced cardiomegaly, craniofacial and somitic anomalies. Both drugs were lethal at 10^–3 mol/l. Comparison of results obtained with 8 drugs shows that the method has a good discriminative power and specificity and that it can be used as a simple, reliable and economical primary screening test, making it possible to reduce the use of animals in toxicological studies.Supported by the grant 4.790.0.84.17 from the Swiss National Science Foundation.
