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.     

生物浮动床处理电厂厂区生活污水

利用"生物浮动床-过滤-臭氧杀菌"技术处理电厂厂区生活污水,耐有机负荷冲击和水力冲击的能力强,对CODcr、氨氮、总磷有较好的去除效果.CODcr总去除率最高可达到95%,出水CODcr稳定在10～30 mg/L;总磷去除率达到50%以上,出水总磷质量浓度低于0.5mg/L;对NH3-N的去除率基本可以稳定在80%以上;浊度消减率可达到84%,细菌杀灭率大于99.9%,出水细菌浓度小于1/L.     

捷联寻的制导弹药的新型卡尔曼滤波器设计

针对捷联制导系统的自身特点,设计出用于估计导弹和目标在弹体坐标系中相对运动状态的卡尔曼滤波器,使滤波与制导在同一个坐标系即弹体坐标系内进行,避免了信息在弹体坐标系和惯性坐标系之间的多次转换,从而减少了信息损失.仿真结果表明,该方法能够满足捷联制导系统的要求.
