蝙蝠葛碱对肾上腺素所致药物性高血压大鼠的影响研究

目的研究蝙蝠葛碱对肾上腺素所致药物性高血压大鼠的影响.方法各组给药前均先给肝素钠500 U单位,模型组注射生理盐水(Saline)10 mL/kg、Ver组(0.98 mL/kg剂量给药组)、低剂量组(2 mg/kg)、中剂量组(4 mg/kg)、高剂量组(8 mg/kg)3个剂量给药组,在注射相应药物之后1~3 min之内,注射重酒石酸去甲肾上腺素注射液0.18 mL/kg.标记给药后各组大鼠的血压变化.结果Dau 2,4,8 mg/kg组和Ver组注射Dau及Ver后,血压下降明显,Dau 8 mg/kg组效果最显著平均动脉压均值降至12.9 kPa.Dau 4,8 mg/kg组和Ver组与Control组比较,统计学差异显著P<0.01.给予NA后,Dau 2,4 mg/kg组及Ver组血压均有所上升,Dau4 mg/kg组和Ver组升高幅度相似,Dau 8 mg/kg组血压上升幅度不足Control组一半(平均动脉压均值为17.6 kPa).且Dau 4,8 mg/kg组和Ver组与Control组比较,有显著差异P<0.01.结论提示Dau可以降低正常大鼠血压,不同浓度的Dau对NA引起的大鼠血压升高有明显的对抗作用.     

与极小非超可解群有关的群的不可约表示

本文讨论有限群在特征为0的代数闭域K上的表示。群G的表示φ称为单项表示,如果φ是G的某个子群的一次表示的诱导表示。如果G的每一个不可约表示都是单项表示,则称G是M一群。本文在§1用指标方法证明了有关群G的不可约表示由子群的不可约表示所诱导的两个定理。然后在§2证明了:极小非超可解群是M-群;可解外超可解群是M-群;若群G是abel正规子群与极小非超可解群的半直积,则G是M-群。     

关于电场推迟效应的讨论

在电磁学教材中,库仓电场E_库不存在推迟效应,感生电场E_库存在推迟效应而使得总电场E=E_库E_库存在推迟效应是作为结论写出的,并未加以证明。本文从电磁场的基本理论出发,证明了以上结论。     

关于分解分量的独立图与导出图的注记

通过反例否定了[1]中关于分解分量的独立图等于导出图的结论。另外,作者证明了分解分量的拟独立图等于它的导出图这一有用的结论。     

关于Finsler空间的子流形

通过对Ｆｉｎｓｌｅｒ内积的讨论，得到了子流形的Ｆｉｎｓｌｅｒ丛上的诱导联络，给出了Ｆｉｎｓｌｅｒ子流形的第二基本形式与法曲率     

张量空间中可合元素图的基本结构

应用诱导生成子图的方法,研究了可合张量的图论性质。通过讨论一个顶点和它的两个相邻顶点的诱导生成子图的结构,指出三角形和平形四边形结构是可合张量的图的基本结构,得到了由图论语言表达的可合张量的充分必要条件。     

Feeding in infancy: Short- and long-term effects on cardiovascular function

Cardiovascular responses of adult organisms to feeding are well characterized and, in general, are understood as acute adaptations required for processing and distributing nutrients. Research over the past several years has shown that infants also have important cardiovascular responses to nutrient intake and that these are regulated by changes in autonomic activity to the heart and vasculature. Recent studies have provided results that suggest these responses in infancy may make an important contribution to the long-term development of cardiovascular function, in particular, adult blood pressure (BP). The purpose of this presentation will be to review the evidence that has led to this conclusion, offer ideas about how this potential early-life shaping of subsequent cardiovascular function may come about, and suggest further studies that will be required in order to characterize the mechanisms responsible for these effects.

Genetic models in brain and behavior research,part IV

Four reviews on the the role of developmental factors in hypertension are introduced and set in historical context. Recent research in the laboratory rat has shown that the preweaning environment makes an important contribution to the level of blod-pressure reached in adult life in genetic models of hypertension. Both of the most commonly used models of hypertension, the SHR and SS/Jr rat strains, exhibit lower BP in adult life, if they are fostered shortly after birth to mothers from their normotensive control strains. It has been suggested that it is the idiosyncratic maternal behavior of the hypertensive mothers which contributes to the elevated BP of their offspring, and it has been amply demonstrated that there is an association between a constellation of behaviors emitted by rat mothers and the adult BP of their offspring in a wide variety of genetic groups (inbred hypertensive animals, F1's and F2's). In addition to the above, maternal environment has been demonstrated to have a significant impact on the pathophysiological response of hypertensive animals to a high salt diet. Being raised by an SHR mother, versus an SS/Jr mother, increases the magnitude of BP increases to a high salt diet, susceptibility to hemorrhagic stroke, body weight loss and the risk of mortality. A variety of physiological systems are undergoing rapid change during the preweaning period and may mediate the effects of differences in the maternal environment. These include the renin-angiotensin system and the peripheral sympathetic nervous system. Nutritional factors may be involved in all of the phenomena referred to above. Thus, any physiological mechanisms that are proposed to link maternal behavior to its effects on the physiology of adult animals should recognize the involvement of nutritional factors. Research on the role of developmental factors such as maternal behavior in genetic models of hypertension is at the interface of two growing disciplines: behavior genetics and developmental psychobiology. The methodological and conceptual contributions of these fields to advancing our understanding of these phenomena is emphasized.
