山西黎城楷侯墓地出土祭祀动物骨骼鉴定与分析

黎城楷侯墓地M10出土祭祀动物57具,包括马、狗、羊、牛、猪五种动物,有马马牛、马马猪和狗羊祭祀组合。M8出土3副狗骨架,其中椁盖板下狗体型巨大。M7出土狗和猪的骨架共4副,M2、M4和M6三座墓各出土1副狗骨架。黎城楷侯墓地出土的这批祭祀动物为研究西周时期畜牧史、用牲礼制等提供了重要考古资料。

三种判定骨龄方法的比较

我们运用李果珍“百分计数法”,哈尔滨医科大学制成的标准图谱法和Tanner-TW2法对哈尔滨市553名7—12岁汉族小学生分别进行骨龄判定,比较了这三种方法估计骨龄的差异,结果表明:李果珍法判定骨龄比其余两种方法准确;图谱法估计的骨龄与李果珍法接近;TW2法不适用于中国北方汉族儿童骨龄判定。

关中地区新石器时代动物遗存研究

关中地区作为中华文明的重要发祥地之一,包含着丰富的新石器时代文化遗存.本文在前人研究的基础上搜集了大量关中地区新石器时代遗址的动物遗存信息,特别是有动物骨骼鉴定报告或相关论文出版的遗址,通过对典型遗址动物群的分析和比较,进一步阐述关中地区新石器时代的气候特征、自然环境以及环境与文化发展的关系,对不同时期农业、家畜饲养、狩猎经济的发展变化以及人类对动物骨骼的开发利用进行探讨.

Culture and Identification of Myoblasts Isolated from Duck Embryos

Using embryonic myoblasts to research the formation and de-velopmental mechanisms of skeletal muscle is becoming a research hotspot. This study aimed to establish a method of isolation, culture and identification of my-oblasts in duck embryos. [Method] Pectoral and leg muscle samples were isolated from the embryos of Gaoyou duck at 13 d of hatching, then disassociated with col-lagenase and trypsin and purified via differential adhesion. The isolated cells were cultured in vitro and detected for the expression of Pax7 protein using immunofluo-rescence technique. [Result] Myoblasts were obtained successful y both from pectoral and leg muscles in duck embryos and these cells proliferated strongly and differen-tiated wel . Immunofluorescence staining showed that more than 95% cells could express Pax7 protein. [Conclusion] In summary, we report the successful establish-ment of a complete system for the isolation, purification, identification and culture of myoblasts from duck embryos.

关于华南古代鳄类问题的一点澄清

古代文献中关于华南地区曾分布有不少凶猛鳄类的描述,许多学者对此抱怀疑态度。70年代珠江三角洲连续出土了大量鳄类骨骼后,这些记载得到了证实。但在鳄类属种的报道上,却又出现了一些混乱现象。最初多数学者认为华南大型鳄鱼属于Crocodilusporosus(学名),中文传统译名为“湾鳄”。
