We administered extracts of the horn of the African Black rhinoceros intragastrically to 7 rabbits, at the same time as injecting bacterial lipopolysaccharide (LPS) intravenously into the rabbits to produce fever. At a dose of horn (50 mg/k...
Heat acclimation: cardiovascular response to hot/dry and hot/wet heat loads in rats [0.03%]

D Moran,Y Shapiro,U Meiri et al.
D Moran et al.
Body temperature, blood pressure (BP) and heart rate (HR) of rats before and after acclimation to heat were studied in chronically cannulated sedentary conscious rats in different hot environmental conditions [hot/dry: 40 degrees C, 20% rel...

M Cengiz
In vivo effects of methyl nitrosourea (MNU) on rat liver glutathione, glutathione S transferase and glutathione reductase have been studied. MNU was injected (20 mg per kg i.r.) weekly for 10 weeks. The animals were killed by decapitation 6...
Blood pressure effects of hydrochlorothiazide, applied to the rat hypothalamus [0.03%]
盐酸氢氯噻嗪对大鼠下丘脑血压的影响
F Bergmann,R Altshuler
F Bergmann
In the search for central actions of hydrochlorothiazide (HCTZ), the drug was injected directly into the hypothalamus (HTH) of hypertensive rats. This caused regular fall of blood pressure (BP) and development of a flat dose-response curve-...
Human red blood cell shape and volume are changed by physiological levels of hydrostatic pressure [0.03%]
生理水平的静水压可改变人红细胞的形状和体积
G Barshtein,L Bergelson,E Gratton et al.
G Barshtein et al.
Application of hydrostatic pressure of several atmospheres (atm), such as that applied in diving or hyperbaric treatment, has been previously shown to induce the release of membrane components into the extracellular medium. As the shape of ...
Distribution of deaths from ischemic heart disease and stroke. Environmental and aging influences in men and women [0.03%]
缺血性心脏病和卒中的死亡分布：环境因素及老龄化对男性和女性的影响

E Stoupel et al.
The goal of this study was to check: 1) links between month of the year (1-12), monthly solar activity (SA) and monthly geomagnetic activity (GMA) with the temporal distribution of deaths from ischemic heart disease (IHD) and stroke in Isra...
Irradiation induced blood flow changes in the breast during radiotherapy--a pilot study [0.03%]
放射治疗过程中胸部血流变化的辐照诱导研究——一项初步研究
M Nitzan,Z Weshler,Z Gimmon et al.
M Nitzan et al.
Skin blood flow and underskin temperature were measured in breasts during the complementary radiotherapy following lumpectomy, using the noninvasive transient thermal clearance method. On average, blood flow and tissue temperature increased...

Y Abend et al.
In this study we show that the pathophysiology of anaphylaxis includes generation of nitric oxide (NO), a very powerful, short-acting vasodilator. Guinea-pigs sensitized to ovalbumin were treated with 200 microgram/kg diphenylene iodonium (...
