荞麦花粉抗贫血作用的实验研究

用荞麦花粉的水提取液进行了抗大白鼠缺铁性贫血的研究，结果表明：荞麦花粉具有和硫酸亚铁相似的抗缺铁性贫血作用．饮用荞麦花粉提取液３５ｄ的大白鼠，生长发育良好，主要脏器未见损害．该研究为荞麦花粉的开发利用提供了实验依据．     

常山县华枝睾吸虫第二中间宿主——鱼类调查

肝吸虫病系人畜共患的寄生虫病,在我省一些地区业已证实某些淡水鱼是该寄生虫的第二中间宿主。我县淡水鱼类品种繁多,淡水鱼中是否也有肝吸虫的囊蚴存在?为此,我们于1992年3～5月对本县淡水鱼类进行了调查,结果如下: 一、调查方法 县城所在地农贸市场采购得鲜活小鱼,经查询系捕于常山外港溪,按不同鱼种分别进行检查,取鱼肉,按每克鱼肉加人工消化液5ml的比例进行消化置于37℃孵育箱内消化5小时至6小时,隔一段时间搅拌一次,然后经120目筛于过滤,留滤液沉淀物,每30分钟换水一次,直至清晰止,以解剖镜或显微镜、寻找沉淀物中的肝吸虫囊蚴。     

不同持续时间的周期性压力对构建组织工程软骨的影响

Objective To determine the best duration for exerting the cyclic pressure under which the tissue-engineered cartilage is constructed. Methods Free chondrocytes isolated from rabbit articular cartilage were seeded into polylactic acid-co-glycolic acid(PLGA) scaffolds after expansion in vitro, and ran-domized into 4 groups. In Groups 1 to 3, chondrocytes were cultured under daily cyclic pressure (0 ～ 200 kPa, 0.1Hz) for 4 hours, 8 hours, 12 hours respectively; Group 4 was a control in which no pressure was exerted. In each group, after 2 weeks of culture, the tissue engineered cartilages were observed in vitro and assessed by his-tological staining of liE. Next, the content of DNA and the secretion of type Ⅱ collagen and GAG in cartilages were detected quantitatively. Results Under the daily cyclic pressure (0 ～200 kPa, 0.1 Hz), the scaf-fold-chondrocytes complex in the group of 8 hours got the largest volume, smooth, lucidus, and elastic surface, the most queuing chondrocytes, and the highest content of type Ⅱ collagen and GAG (P < 0.01). Conclusions Since chondrecytes are baro-senstive, the metabolism of chondrocytes can be affected by the time of cyclic pressure. Under the effect of 0 ～200 kPa, 0.1Hz, the daily cyclic pressure of 8 hours may be optimal for chondrocytes to multiply and synthesize extracellular matrixes such as type Ⅱ collagen and GAG.
