小白鼠体温調节动态过程在X射线致死剂量照射前后的变化
射线 体温調节 小白鼠
2009/1/14
1.引言放射病的形成是一个复杂的过程。按一般概念,细胞或組織分化愈高,似乎愈不易受到損伤,但从机体統一的观点着眼,損伤也可能首先涉及分化最高的神經系統。闡明放射病的形成过程是探索其发病机制的必要基础。而放射病的发展及其是否会引起机体死亡,則根据目前的科学水平,还很难給以推断;因此,寻找适当指标来解决这些預后問題,显得非常重要。
应用示踪原子法研究猪、兔对小球藻消化吸收及在体内的运转和分布
小球藻 兔 猪 示踪原子法
2009/1/12
小球藻营养价值高,繁殖快,在我国南方整年都可以繁殖,是家畜的一种饲料。但是,家畜对小球藻能消化吸收多少呢?有的研究者认为小球藻细胞壁厚,不易被功物消化吸收,有的学者认为小球藻营养价值高是无价之宝。这次,我们利用了示踪放射性同位素P~(32),来研究猪和兔,对小
应用示踪原子研究青、草、鲢、鳙、鲤等鱼类对单细胞缘藻的消化吸收机制
单细胞缘藻 鱼类 示踪原子
2009/1/12
在鱼类对单细胞绿藻的消化机制方面,国内外学者都曾作过一些工作,但由于以往所采用的方法大部分都为一般生物学和化学分析方法,因此就必然产生了某些局限性。例如有关消化生理方面的消化速度和消化吸收后某些营养因子在体内的代谢分布,就很难用上述方法来获得确切的结论。应用示踪原子来解决和探索鱼类的消化生理机制具有独特的效能,同时这种方法也力研究鱼类的其他微观现象提供了客观的可能性。下面把我们在这方面所进行的...
用X射线处理家蚕卵对其生长发育的影响
生长发育 家蚕卵 X射线
2009/1/9
用X射綫在孵化前处理蚕卵,100伦者有加速孵化,提高孵化率的作用;500伦者略見抑制;1000伦者則有抑制作用。本文将继續探討射线处理蚕卵后,对其生长发育以及蚕茧的产量的影响。
电离辐射对动物代谢的影响
动物代谢 电离辐射
2008/12/29
一、引言 本文试图从动物的整体水平出发,用矛盾分析的方法来叙述和讨论那些和电离辐射对高待动物代谢影响有关的文献资料;并将着重讨论蛋白质代谢和代谢反应的协调问题。 我们评述文献资料时,力图用唯物辩证法作为指导思想,即认为外因是变化的条件,内因是变化的根据,外因通过内因而起作用。电离辐射对生物机体的作用是电离辐射这个外因通

C57BL/6小鼠听皮层脑片的长时程增强特性
C57BL/6 小鼠 听皮层脑片
2008/3/4
采用脑片细胞外记录群体细胞兴奋性突触后电位方法，在成年C57BL/6小鼠听皮层上，研究长时程增强（long-term potentiation, LTP）特征。用100 Hz高频电脉冲刺激听皮层白质，可在听皮层灰质Ⅱ/Ⅲ层记录到明显的LTP。根据条件刺激后LTP的变化特征，将其分为缓慢上升（A类）和短暂快速上升（B类）两种类型。使用模拟的θ节律刺激参数，可更有效地诱导听皮层LTP，其群体细胞兴...
100 Hz ~ 100 MHz蛙骨骼肌介电谱的椭圆壳理论解析
骨骼肌(Skeletal muscle) 介电谱(Dielectric spectroscopy) 浓厚系椭圆壳理论(Dense ellipsoidal-shell theory) 电导率(Conductivity) 介电常数(Permittivity)
2008/3/4
在100 Hz ~ 100 MHz频率范围内，应用浓厚系介电椭圆壳理论分析了蛙骨骼肌介电谱，提出了蛙骨骼肌细胞的椭圆壳模型参数。讨论了骨骼肌介电谱的高频段平行方向与垂直方向的电导率不相等的理论问题。明确了决定骨骼肌高频率段（106~108 Hz）介电数据的物质基础主要是骨骼肌细胞内部的肌原纤维，其次是胞浆内的微小颗粒（线粒体、肌质网）。
The dielectric spectroscopy...
