ZARINS, CHRISTOPHER K,, AND DAVID B, SKINNER. Hemodynamics and blood flow distributiun following prolonged circulation at 5°C. Am. J. Physiol. 229(Z) : 275-278. 1975 .-Circulation was maintained in profoundly hypothermic dogs for 8 h at temperatures below 10°C. During cooling to 5°C cardiac output and blood pressure decreased and peripheral resistance rose. Thereafter, circuIatory dynamics rema...

in the present study blood was collected from dogs (n=110) after clinical examinations and recording of necessary information(age, sex, breed and housing) examined by modified knott method. periodicity of the microfilaria in peripheral blood circulation, was determined through blood collection from a dog each hour for 72 hours. number of microfilaria in each ml of the blood samples was calculat...

BACKGROUND Rice vinegar (RV) and white vinegar (WV) as daily flavoring, have also used as accessory in traditional Chinese medicine processing. As we know, the promoting blood circulation efficiency could be enhanced when herbs processed by vinegar. Number of reports focused on health benefits derived by consumption of vinegar. However, few concerned the blood circulation bioactivity. METHODS...

In the face of an oversupplied world pig market only the most efficient producers will stay in business. By and large these will be the operations that are able to more successfully exploit the genetic potential of their animals. Similarly, only those breeders who are able to demonstrate sustained genetic improvement will sell stock to the smaller number of large producers who are left. Althoug...

A novel model of the leptomeningeal collateral circulation is created by combining data from multiple sources with statistical scaling laws. The extent varied defining a vessel probability. Blood flow and pressure are simulated using one-dimensional steady state blood model. vessels provide significant during stroke. drop over an occlusion predicted ranges between 60 85 mmHg depending on circul...

While health risks from smoking cigarettes are well known, little is known about the health risks of using smokeless tobacco (ST). The aim of this study was to evaluate the effect that ST in the form of oral use of snus with nicotine and snus without nicotine has on peripheral skin blood circulation. 21 young habitual users of snus with nicotine participated in this study. Under controlled cond...

RATIONALE Impaired endothelium-dependent vasodilation has been documented in patients with sleep apnea. This impairment may result in blood flow dysregulation during apnea-induced fluctuations in arterial blood gases. OBJECTIVES To test the hypothesis that hypoxic and hypercapnic vasodilation in the forearm and cerebral circulation are impaired in patients with sleep apnea. METHODS We expos...
