Stimulation of glucagon and inhibition of insulin secretion evoked from carotid baroreceptors.

The influence from carotid baroreceptors on portal immuno-reactive glucagon and insulin levels and on arterial plasma glucose concentration was studied in vagotomized cats by sectioning of the sinus nerves. Such a complete elimination of the afferent baroreceptor discharge caused a prompt and pronounced increase in the glucose and glucagon levels, whereas the insulin concentration significantly decreased. The role of vascular barorecptors in the hyperglycemic response to hemorrhage is discussed.     

Genetic control by the HLA region of the immune response to factor VIII in hemophilic patients]

In 10 sibships of haemophilic A patients, every one including 1 haemophilic brother with an antibody to factor VIII and 1 haemophilic brother without antibody, pattern of HLA segregation was analysed. All sibships were HLA haploidentical or different and not HLA identical. This fact suggested a linkage between the major histocompatibility complex and an "Ir" gene to factor VIII.     

Effect of insulin on immunological phagocytosis by macrophages.

It was shown that, in physiological concentrations, insulin enhances, in vitro, the immunological phagocytosis of sensitized sheep erythrocytes by cultured mouse peritoneal macrophages. Insulin seems to stimulate macrophage phagocytosis as a cholinomimetic agonist by increasing the intracellular levels of cyclic GMP.     

Pyrogen fever in rabbits pretreated with p-chlorophenylalanine or 5, 6-dihydroxytryptamine.

The hyperthermic effect of a bacterial pyrogen has been studied in rabbits pretreated or not with p-chlorophenylalanine or 5, 6-dihydroxytryptamine. The results obtained indicate that a selective reduction of cerebral 5-hydroxytryptamine levels by these drugs do not significantly affect pyrogen hypertermia.     

片状化石燃料的循环流化床燃烧(Ⅰ)--片状颗粒的形貌描述和流态化阻力特征描述

比较了不同球形度概念对片状化石燃料的描述效果,研究了片状化石燃料球形度变化对其流态化特征的影响.分析了Krumbein球形度为0.1～0.4的京西无烟煤在一台50MW循环流化床锅炉上表现出来的特殊现象,如运行床温和炉膛压力大幅度波动、依靠排放冷渣保持稳定运行,揭示了这些现象发生的原因.     

浸泡法制备吸附制冷用复合吸附剂

以分子筛为基材通过浸泡CaCl2和SrCl2溶液的方法制备复合吸附剂.在模拟制冷条件下,对以不同浓度溶液制备的复合吸附剂的吸附、解吸性能进行了测定,并将吸附解吸性能最好的复合吸附剂在自制的模拟制冷装置上进行了制冷实验.结果表明,复合吸附剂具有良好的吸附、解吸性能,最大吸附量达51.6%,解吸率可达69.3%,在模拟制冷装置上系统的制冷系数达0.25,单位吸附剂的制冷功率为0.072 W/g,符合太阳能吸附制冷的要求.     

红毛五加多糖的分离纯化和表观分子质量测定

红毛五加经热水浸提，用Sevag法脱蛋白，经DEAE—cellulose 32离子交换层析和Sephacryl S-200HR凝胶层析纯化得到3个主要多糖组分：AHP-Ⅰ、AHP-Ⅱ、AHP-Ⅲ，经HPLC和Sephacryl S-300HR凝胶层析鉴定，3种多糖均为均一组分，HPLC测定AHP-Ⅰ、AHP-Ⅱ、AHP-Ⅲ的表观分子质量分别为：7．0kD、59．5kD和12．9kD，Sephacryl S-300HR凝胶层析进行验证，得到相似结果．

高校校园景观设计之我见

校园景观规划设计是高校整体形象的关键,是校园文化的重要部分,对于学生德智体全面发展、树立教育品牌、提高教育质量、增强校园的凝聚力、向心力都具有重要现实意义。要做好大学校园景观规划需要抓住三个关键:主体建筑体系(出入口、校园中心区、开敞空间)、交通系统(步行和自行车交通系统、机动车及其停放系统)、景观系统(植物景观系统、文物和纪念物规划)。
